Description

Elements and System for Wound Treatment

TECHNICAL FIELD

[001] The present disclosure relates to a field of medical devices. More particularly, the present disclosure relates to systems, methods and kits for use in wound treatment.

BACKGROUND

[002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

[003] References considered to be relevant as background to the present disclosure are listed below:

US 9,180,142

WO 2019/058375 WO 2019/150355 WO 2021/205457 WO 2022/168099

[004] Acknowledgement of the above references herein is not to be inferred as meaning that these are in any way relevant to the patentability of the device/ system/ method disclosed in the present disclosure.

[005] US patent publications 9,180,142 and 10,111,979 disclose a wound treatment procedure by which blood is coagulated and the so-formed blood coagulant is applied onto a wound with a dressing material. Further, PCT publications WO 2019/058373, WO 2019/058375 and WO 2019/150355 disclose methods, devices, and systems for dressing wounds with a blood coagulant-comprising dressing. The blood clotcomprising dressing is, typically, prepared from blood taken from a patient. As the blood sample to be withdrawn is of a relatively small amount (as compared to that of a blood donation to a blood bank), e.g., 10-20 ml, the blood sample is typically drawn into a vacuum -holding test tube that is sealed by an elastic, typically rubber, stopper, of the kind used in blood tests, and then has to be withdrawn from the test tube. As the test tube is sealed, the blood withdrawal, typically with a syringe has to be against the vacuum inside the tube and this may be challenging. [006] PCT publication WO 2021/205457 discloses a device that allows extraction of the blood from a test tube by pumping a gas, e.g., air, into the test tube through one conduit, whereupon blood is extracted out of another conduit into a blood coagulation molding device. Use of coagulated blood mass in the healing process of an abnormal hollowed space, such as an annal fistula. Method and a kit for treating an abnormal hollowed space of a subject, such as a fistula, pilonidal sinus or a stoma are disclosed in PCT publication WO 2022/168099.

[007] Withdrawing blood from a test tube by a syringe is challenging as there is a need to overcome the vacuum that develops within the test tube.

The connector device 100 is further adapted to couple with a syringe containing a coagulating agent, such as syringe 400 of FIG. 4, at a second end 104 of the connector device 100. In said embodiment, when the connector device 100 is coupled with the test tube and the syringe, the connector device 100 facilitates a fluid communication between the test tube and the syringe, such that the blood mass contained in the test tube is drawn into the syringe, by a movement of a plunger of the syringe, to mix at least a portion of the blood mass with the coagulating agent contained in the syringe, and form a coagulating blood mass.

[100] The coagulating blood mass formed in the syringe may be applied or injected onto a wound for treating the wound by forming a blood coagulant in or on the wound. Without derogating from the general teaching of the present disclosure, a subject may be a patient suffering from the illness or wound, and may be a human or a non-human animal. Further, the wound may be a wound formed on the surface of a skin or another exposed surface, may be a penetrating wound, such as an abnormal cavity that is formed in human or non-human animal due to or in a result of a certain medical condition. For example, the wound may be a fistula, e.g., an anal fistula, a stoma opening, or a pilonidal sinus. Also, the wound may be naturally occurring as a result of a certain medical condition, may be a consequence of an injury, may be a by-product of a surgical procedure, etc.

[101] In accordance with the present disclosure, the blood mass is whole blood, typically, an autologous blood, withdrawn from the subject. The blood mass is collected in a blood-collection test tube that typically holds a vacuum, maintained by a stopper of the test tube. An exemplary test tube 200 containing the blood mass 202 is shown in FIG. 5.

[102] Further, without derogating from the general teaching of the present disclosure, FIG. 4 illustrates an exemplary syringe 400. The syringe 400 is adapted to be coupled with the connector device 100, the coupling being, for example, as illustrated, through a Luer fitting - the syringe having an exemplary illustrated female-type Luer adapter for coupling to an illustrated male-type Luer adapter of a syringe port of the connector device 100. As can be appreciated, in other embodiments the syringe may have a male- type Luer adapter and the syringe port a female one; or the coupling may be by a different type of fitment. The syringe 400, shown in Fig. 4, comprises a hollow syringe barrel 402 with a front end 404 and an opposite rear end 406. A plunger 410, with a piston 412 is disposed within the syringe barrel 402, the plunger 410 typically made of or comprises an elastomeric material to secure a fluid-tight seal with walls 408 of the syringe barrel 410. Further, the front end 404 of the syringe 400 is also configured to be coupled with a needle or an application tube, by a similar type of fitment as noted above. Said needle may be any suitable needle used in medical procedures for applying or injecting or transferring or administering contents contained in the syringe barrel 402 to the subject. In some embodiments, the front end 404 of the syringe barrel 402 is configured to be coupled or fixed with an elongated application tube, e.g., a plastic tube, suitable for applying or injecting or transferring or administering the contents contained in the syringe barrel 402 to the subject or the patient.

[103] Referring again to FIG. 4, the syringe 400 further comprises a coagulating agent 420. The coagulating agent 420 is contained in the syringe barrel 402 between the piston 412 and the front end 404 of the syringe barrel 402, as shown in FIG. 4. The coagulating agent 420 may be a dry particulate matter, for example, a finely ground or milled solid, a powder form, a lyophilizate, etc. The coagulating agent 420 may be one or more first agents that induce blood coagulation and/ or one or more second anti-anticoagulants that counteracts action of anti -coagulants. Exemplary coagulating agents 420 include Kaolin, Calcium salts, Magnesium salts, negatively charged phospholipid and protamine sulfate.

[104] Referring again to FIG. 1, the connector device 100 is shown. The connector device 100 comprises an adapter body 110, a test tube port 120, a syringe port 130 and a gas inlet port 140. Within the general scope of teachings of the present disclosure, the test tube port 120 is adapted to be coupled with a stopper-sealed test tube, for example, the test tube 200, seen in FIGS. 5 and 6. In an embodiment, the adapter body 110 comprises a test tube adapter 122 at the test tube port 120 that is configured to facilitate coupling of the test tube port 120 with the test tube 200. The test tube 200, as can be seen in FIGS. 5 and 6, is a stopper-sealed test tube that includes or has a closure 208, as seen in FIG. 7, that includes an elastomeric stopper 210, seen in FIG. 7, sealing the test tube’s opening, typically, but not exclusively, made from rubber. The test tube 200 that may contain a blood mass (for example, the blood mass 202) under vacuum 204 held by the stopper 210. In an embodiment, the test tube adapter 122 is formed in the general shape of a hollow cylinder 124 having an open end 126. In this embodiment, the inner diameter of cylinder 124 corresponds to the outer diameter of the closure 208, which ensure tight fitting when the test tube 200 is coupled with the connector device 100, and hence supports the test tube 200 and holds it in a desired position.

[105] The syringe port 130 is adapted to be coupled with a syringe, for example, the syringe 400, as shown in FIG. 4. In an embodiment, the adapter body 110 comprises a syringe adapter 132 at the syringe port 130. The syringe adapter 132 is configured to facilitate coupling of the syringe port 130 with the syringe 400, for example it may comprise a Luer-type fitment for coupling with a counterpart Luer-type fitment of the syringe 400.

[106] The gas inlet port 140 opens to the atmosphere . If desired, it may also be coupled with an external source of gas (not shown). The gas inlet port 140, that can best be seen in FIG. 3, defines a channel 144 within a body 142. The channel 144 is fluidically linked at its inner end to a second fluid conduit 160 of the connector device 100. Further, in some embodiments, the gas inlet port 140 comprises a filter 146 for filtering inflowing gas. In the illustrated embodiment, the gas inlet port 140 includes a Luer-type fitment while there may be other type of fitments in other embodiments or where port 140 intends to be open to the external atmosphere, it may include no fitment at all.

[107] The connector device 100 further comprises at least one first fluid conduit 150 that extends through the adapter body 110 between the test tube port 120 and the syringe port 130. In an exemplary embodiment shown in FIGS. 1 to 3, the at least one first fluid conduit 150 is embodied as one first fluid conduit 150 that comprises a first end projection 152 at the test tube port 120 of the adapter body 110, configured to pierce through a pierceable seal of an entity, when the entity is being coupled to the connector device 100. For example, the first end projection 152 of the at least one first fluid conduit 150 is configured to pierce through the elastomeric stopper 210 of the test tube 200, when the test tube 200 is being coupled to the connector device 100. In an embodiment, the first end projection 152 comprises a tapered or sharpened tip 154 for piercing the elastomeric stopper 210 of the test tube 200. In a further embodiment, the first end projection 152 comprises a bevelled end, for example, shaped like a needle, for piercing the elastomeric stopper 210 of the test tube 200.

[108] The connector device 100 further comprises at least one second fluid conduit 160 that extends through the adapter body 110 between the test tube port 120 and the gas inlet port 140. In the exemplary embodiment shown in FIGS. 1 to 3, the at least one second fluid conduit 160 is embodied as one second fluid conduit 160. In accordance with the present disclosure, the at least one second fluid conduit 160 comprises a second end projection 162 formed at the test tube port 120 of the adapter body 110. The second end projection 162 is also configured to pierce through the pierceable seal of the entity, when the entity is being coupled to the connector device 100. For example, the second end projection 162 of the at least one second fluid conduit 160 is configured to pierce through the elastomeric stopper 210 of the test tube 200, when the test tube 200 is being coupled to the connector device 100. In an embodiment, the second end projection 162 comprises a tapered or sharpened tip 164 for piercing the elastomeric stopper 210 of the test tube 200. In a further embodiment, the second end projection 162 comprises a bevelled end, for example, shaped like a needle, for piercing the elastomeric stopper 210 of the test tube 200.

[109] In this embodiment, the first fluid conduit 150 and the second fluid conduit 160 are arranged parallel to each other. Further, one or both of the at least one first fluid conduit 150 or the at least one second fluid conduit 160 may be constituted by a metal tube.

[HO] The test tube port 120 and the syringe port 120 of the adapter body 110 are, respectively, adapted for coupling with the test tube 200 and the syringe 400. When the test tube 200 is coupled to the test tube port 120, as seen in FIGS. 5 to 7, the first end projection 152 of the at least one first fluid conduit 150 and the second end projection 162 of the at least one second fluid conduit 160 pierce the elastomeric stopper 210 of the test tube 200 such that the first end projection 152 and the second end projection 162 are received in the test tube 200. The at least one second fluid conduit 160 enables the fluid communication between the test tube 200 and the gas inlet port 140 through channel 144.

[Hl] Further, as also seen in FIG. 5, when the syringe 400 is coupled to the syringe port 130 of the connector device 100 (to which the test tube 200 is coupled), the at least one first fluid conduit 150 enables the fluid communication between the test tube 200 and the syringe 400. When the plunger 410 of the syringe 400 is actuated to draw the blood mass 202 contained in the test tube 200, the at least one first fluid conduit 150 facilitates drawing the blood mass 202 from the test tube 200 into the syringe 400 so as to mix the blood mass 202 with the coagulating agent 420 contained in the syringe 400, thereby forming the coagulating blood mass 206, as seen in FIG. 6. Simultaneously, the at least one second fluid conduit 160 facilitates the fluid communication between the atmosphere/ external source of gas and the test tube 200 so that the gas is introduced into the test tube 200 when the blood mass 202 is drawn from the test tube 200.

[112] Without derogating from the general scope of the teaching of present disclosure, the connector device 100, along with the components thereof, for example, the adapter body 110, the gas inlet port 140, the at least one first fluid conduit 150 and the at least one second fluid conduit 160, facilitates easy and convenient withdrawal of the blood mass 202 from the test tube 200, against the vacuum 204 that is present and/ or develops within the test tube 200. Particularly, the at least one second fluid conduit 160 permits withdrawal of the blood mass 202 from the test tube 200 while introducing gas, for example, atmospheric air, thereinto.

[113] As illustrated in the exemplary embodiment of FIGS. 1, 2, 5 and 6, the test tube port 120 and the syringe port 130 of the adapter body 110 of the connector device 100 are disposed opposite to each other. Further, in an embodiment, the test tube adapter 120 is aligned co-axially with the syringe adapter 130. However, without derogating from the general scope of teachings of the present disclosure, a person skilled in the art can modify the constructional features of the connector device 100 such that the test tube port 120 and the syringe port 130 can be provided at any angle with respect to each other, not necessarily 180 degrees apart (i.e., opposite to each other). In said modifications, the test tube 200 and the syringe 400 can be coupled with the connector device 100 at any desired angle, not necessarily 180 degrees apart (i.e., opposite to each other).

[114] Further, in the embodiment where the test tube adapter 122 is formed in shape of the hollow cylinder 124 having the open end 126, the first end projection 152 and the second end projection 162 of the at least one first fluid conduit 150 and the at least one second fluid conduit 160, respectively, project into an interior of the hollow cylindrical test tube adapter 122. Further, when the test tube 200 is coupled with the connector device 100, the test tube adapter 122 receives the stopper-sealed end of the test tube 200 in a manner such that the first and second end projections 152, 162 pierce the elastomeric stopper 210 of the test tube 200. Also, the hollow cylinder of the test tube adapter 122 provides support to the test tube 200 and holds the test tube 200 in a desired position.

[115] While the coupling of the syringe 400 and the test tube 200 to the connector device 100 and the drawing of blood into the syringe is described in FIGS. 5-6 in relation to the embodiment thereof shown in FIG. 1, use may also be made with a connector device 100A of the embodiment shown in FIGS. 2 and 3, which differs from device 100 in that test tube port 120A of connector device 100A does not have a cylindrical tube receptacle such as cylinder 124, but rather a screw-threaded adapter 122A that is configured for coupling with a matching closure with an internal (femaletype) screw threading that can be screw-fitted thereto. Other elements of connector device 100A are substantially the same as those of connector device 100 and are indicated by the same reference numerals.

[116] In other embodiment, the coupling between the test tube 200 and the test tube port 120 may be achieved by a variety of different means and, even just through permitting only the first and second end projections 150,160 to pierce the stopper with the coupling being achieved in this manner without any other coupling element.

[117] Further, in accordance with the present disclosure, a system 501 for coagulating a blood mass, for example, the blood mass 202, is disclosed. An exemplary system 501 for coagulating the blood mass 200 is shown in FIGS. 5 and 6. In an embodiment, the system 501 comprises a test tube, for example, the test tube 200, a syringe 600 and a connector device 500 couplable with the test tube 200 and the syringe 600. The test tube 200 may comprise any known test tube known in the medical field. Typically, the test tube 200 is formed of a medical grade material (for example, glass, plastic, another polymeric mater, etc.) and in shape of a cylindrical tube having an open end. The open end of the test tube is sealed by a closure 208 that includes an elastomeric stopper 210 that may be made of any suitable medical grade elastomeric material such as rubber. Further, the test tube 200 is adapted to contain the blood mass 202 and hold a vacuum 204 (as known, the vacuum being the driving force for drawing blood therein, e.g., for venous blood withdrawal from a subject). The test tube 200 may be such used for blood collection. The blood mass 202 is whole blood, typically, an autologous blood, withdrawn from a subject, for example, a human or non-human animal. The blood mass 202 is collected in the test tube 200 that typically holds the vacuum 204, maintained by the elastomeric stopper 210 of the test tube 200.

[118] The system 501 comprises the connector device 500, that in an exemplary embodiment, have all the structural and functional features similar to that of the connector device 100, 100A described above, and elements in FIGS. 5-6 with a similar function to those of FIGS. 1-3, are indicated by the same reference numeral shifted by 400. For example, the elements 510, 550 and 560 in FIGS. 5 and 6 have the same functionality as elements 110, 150 and 160 in FIGS. 1-3, respectively. Similarly, elements of the syringe 600 with a similar function to those of FIG. 4, are indicated by the same reference numeral shifted by 200. For example, the elements 602 and 620 have the same functionality as elements 402 and 420 in FIG. 4, respectively. The reader can thus refer to the description above for explanation of structure or function of such elements.

[119] In an embodiment, the system 501 comprises an elongated application tube or a needle 690, as shown in FIG. 8, adapted to be coupled or fixed to an outlet port 630 of the syringe 600. Said elongated application tube or the needle 690 may be any suitable tube or needle used in medical procedures for applying or injecting or transferring or administering the contents, for example, the coagulating blood mass 206, contained within the syringe 600 to a site of need, for example, a wound, in a body of the subject. In a typical embodiment, the coagulating blood mass 206 is applied or transferred to the wound while the coagulating blood mass 206 is still flowable, and hence injectable out of the syringe 600. The coagulating blood mass 206, depending on the nature and concentration of the coagulating agent 620, may become too viscous for injection after a time period of about 4 to 15 minutes, and accordingly, the coagulating blood mass 206 is applied or transferred out of the syringe 600 within a time period of about 1 to 10 minutes, or up to about 3 or 4 minutes, from mixing of the blood mass 202 with the coagulating agent 620. In an embodiment, the system 501 further comprises one or more blood mass collection elements (not shown), for example, needles, etc., for withdrawing the blood mass 202 from the subject and transferring the blood mass 202 to/ into the test tube 200.

[120] Further, the present disclosure provides a method of coagulating the blood mass 202. Without derogating from the general scope of teachings of the present disclosure, the method of coagulating the blood mass 202 may be performed by the system 501 of coagulating the blood mass 202 described above. The method comprises coupling the syringe 600 containing the coagulating agent 620, to the syringe port 530 of the connector device 500. The method further comprises coupling the stopper-sealed test tube 200 containing a volume of the blood mass 202, to the test tube port 520 of the connector device 500, such that the first and second end projections 552, 562 of the at least one first fluid conduit 550 and the at least one second fluid conduit 560, respectively, pierce the elastomeric stopper 210 of the test tube 200. The method furthermore comprises drawing the blood mass 202 from the test tube 200 into the syringe 600, through the at least one first fluid conduit 550, for mixing the blood mass 202 with the coagulating agent 620 to form the coagulating blood mass 206. In an embodiment, the method comprises, prior to coupling the test tube 200 with the connector device 500, withdrawing the blood mass 202, by one or more blood mass collection elements known per se, from the subject and transferring the blood mass 202 to/ into the test tube 200.

[121] The coagulating blood mass 206 so formed in the syringe 600, by the method of coagulating the blood mass 202, may be applied or injected onto a wound of the subject for treating the wound by forming a blood coagulant on the wound. The coagulating blood mass 206 is applied or injected through the elongated application tube or the needle 690 couplable with the syringe port 630.

[122] Further, in accordance with the present disclosure, a wound treatment system is disclosed. By an embodiment of the present disclosure, the wound treatment system comprises the elements of the system 501 of FIGS. 5 to 6.

[123] Further, the present disclosure provides a method of treating a wound. Without derogating from the general scope of teaching of the present disclosure, the method of treating the wound may be performed by the wound treatment system described above.

[124] The elements of the system 501 of FIGS. 5-6 and 8 may also be part of a kit of parts also provided by this disclosure. The kit of parts may also comprise blood withdrawal elements for withdrawing a blood mass from the subject as well as others.
