Slow Release Needles

technical field

The invention relates to the technical field of medical equipment, in particular to a slow-release needle.

Background technique

Acupuncture point embedding therapy refers to a method in which needles are inserted into the skin, fixed and left for a certain period of time to use their continuous stimulating effect to treat diseases.

In the clinical treatment of modern Chinese medicine, acupoint embedding therapy has become a very routine treatment method. For example, acupoint embedding therapy can be used for nervous headache, migraine, stomach pain, biliary colic, hypochondriac pain, wrist and ankle sprain, etc. Moreover, it has a good curative effect on certain chronic diseases, such as: neurasthenia, high blood pressure, asthma, irregular menstruation, hemifacial spasm, eyelid movement, enuresis, frequent urination, arthralgia syndrome, etc. In modern medical cosmetology, acupoint embedding therapy is popular because of its weight loss effect.

Traditional acupoint embedding devices are mainly divided into four types:

1. Granular intradermal needle: also known as wheat grain intradermal needle, the needle body is about 1 cm long, the needle handle is shaped like a wheat grain or circular, and the needle body and the needle handle are in a straight line; operation method: after skin disinfection, apply granular When embedding the intradermal needle, hold the needle body with tweezers first, and insert it horizontally along the subcutaneous side. Generally, the direction of the needle is perpendicular to the direction of the meridian, and the needle body penetrates about 0.8 to 1.3 cm, and then fixed with adhesive tape along the direction of the needle body.

2. Push-pin type intradermal needle: also known as thumbtack type intradermal needle, the needle body is about 0.2-0.3 cm long, the needle handle is circular, and the needle body and the needle handle are vertical; after skin disinfection, use tweezers or fingers to hold the needle Aim the needle at the selected acupoint, open the skin where the needle is located with the thumb and index finger of the left hand, quickly twist and press the right hand to push the needle in, and then apply it with adhesive tape to fix it. Another method is to first pick up the needle with tweezers, stick the needle loop on a small piece of adhesive tape, and then hold the adhesive tape and press the adhesive tape together with the needle into the acupoint.

3. Ordinary filiform needles or elongated needles: Operation method: for ordinary filiform needles, first cut the handle of the needle short (to facilitate fixing with tape). On the basis of the general needling method, after deep puncturing, lift the needle under the skin, and then puncture horizontally with a flat needle; after inserting the needle 0.5 to 1.5 inches along the skin, fix it with an external adhesive tape.

4. Catgut embedding: Cut the catgut to a suitable length and place it in 75% alcohol for later use. After selecting the acupuncture points on the patient's body to be embedding. Disinfect the needle of the No. 8 syringe, insert the catgut into the needle, and use the No. 8 syringe to pierce the selected acupoint to a certain depth after the equipment is prepared, then push the catgut out of the needle with an acupuncture needle, and then pull out the needle.

Traditional acupuncture (thread) therapy also has its own shortcomings, such as:

1. Granular type intradermal needles and push nail type intradermal needles are smaller in size and shorter in length, and oblique pricking techniques are often used during operation, which greatly limits the scope of application of this type of needle. Acupuncture points (such as Tianshu) are not effective;

2. Ordinary filiform needles or elongated needles: In this treatment, ordinary filiform needles are embedded in the skin and then fixed with adhesive tape, which makes the wound unable to close and the long-term exposure of the needles also increases the possibility of wound infection;

3. Catgut embedding:

This type of therapy uses No. 8 injection needles, which are thicker, and different from acupuncture needles, the needles of the syringes have an oblique cutting surface, so this cutting surface may scratch blood vessels during the operation. Nerve damage caused by bleeding or cutting into the nerve.

Contents of the invention

The object of the present invention is to provide a slow-release needle, which can conveniently complete needle-buried injection, and has simple operation and small wound.

In order to solve the above technical problems, an embodiment of the present invention provides a slow-release needle, including a sleeve with a cylindrical cavity inside, and the cavity is used to hold a frozen needle. Wherein, the head end of the cannula has a needle port with a diameter greater than or equal to the cavity, and the needle port communicates with the cavity; the tail end of the cannula is provided with an ejection mechanism for ejecting the frozen needle from the needle port and detaching from the slow-release needle.

Compared with the prior art, the embodiment of the present invention puts the freezing needle in the cannula, and when the cannula is inserted into the human body, it is ejected by the pop-up mechanism, so that the freezing needle can stay in a deeper position in the human body. Since only two steps of insertion and ejection are required during operation, the operation is simple and can even be operated by the patient himself, which is suitable for home health care use. Since only a wound with the diameter of the casing is left on the skin surface, the wound is small and is not easy to cause wound infection.

Preferably, the ejection mechanism includes an elastic piece connected to the tail end of the cavity and a blocking piece for blocking the elastic piece, and the blocking piece can move relative to the elastic piece. Wherein, the elastic member is initially in a compressed state and resists the blocking sheet, and after the blocking sheet is removed, the elastic member restores its deformation and ejects the freezing needle. The elastic member is blocked by the blocking sheet, so that the deformation of the elastic member can be controlled.

Preferably, the blocking piece runs through two opposite side walls of the sleeve. In this way, by pushing the blocking sheet inwardly from one of the side walls, the blocking sheet can be extruded from the casing, thereby recovering the deformation of the elastic member.

Preferably, the blocking piece is connected to the outer wall of the sleeve through a pivot shaft, and the blocking piece can pivot radially relative to the sleeve through the pivot shaft. At this time, the blocking piece can not only stagger the deformation direction of the elastic member by rotation, but also return to its original position by rotation. And the blocking sheet is not easy to fall off or lose, which will enable the slow-release needles provided by the embodiments of the present invention to be reused, greatly reducing the cost and reducing environmental pollution.

Based on the arrangement of the above two blocking pieces, preferably, at least a part of the blocking piece protrudes from the outer wall surface of the casing, wherein the protruding part is used to move the blocking piece. At this point, the barrier sheet can be manipulated without the aid of external tools. Certainly, preferably, the slow-release needle device may also include a thimble connected to the outer wall of the cannula through a flexible belt, and the thimble is used to push the blocking sheet.

In addition, preferably, the slow-release needle further includes a hub detachably connected to the cannula, a needle groove communicating with the cavity is provided in the hub, and the diameter of the needle groove gradually decreases from the direction toward the cavity to the direction away from the cavity . The needle groove in the sleeve can be directly frozen to form the needle after the liquid of the frozen needle component is perfused. Further, preferably, the diameter of the connecting portion between the needle groove and the cavity is greater than or equal to the diameter of the cavity. When the diameter of the connecting part of the needle groove and the cavity is equal to the diameter of the cavity, the freezing needle can enter the patient's body more smoothly; when the diameter of the connecting part of the needle groove and the cavity is larger than the diameter of the cavity, the barb formed at the needle It can prevent the frozen needle from being carried out by the cannula.

In addition, preferably, the slow-release needle further includes a cleaning rod, the diameter of which is smaller than that of the cavity, and the cleaning rod is used to reset the ejection mechanism.

Further, preferably, the ejection mechanism includes an elastic piece connected to the tail end of the cavity and a blocking piece for blocking the elastic piece, and the blocking piece can move relative to the elastic piece. The elastic part is initially in a compressed state and against the blocking sheet, and after the blocking sheet is removed, the elastic part resumes its deformation and ejects the freezing needle. The cleaning rod includes a body section and a replacement section located at the top of the body section, and the thickness of the replacement section is the same as that of the blocking sheet.

Preferably, the freezing needles can be chitin freezing needles, physiological saline freezing needles or antibiotic freezing needles.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

The first embodiment of the present invention relates to a sustained-release needle, as shown in FIG. 1 , which includes a sleeve 2 with a cylindrical cavity 21 inside, and the cavity 21 is used to hold a frozen needle. Wherein, the head end of cannula 2 is provided with the needle mouth 22 that diameter is greater than or equal to cavity 21, and needle mouth 22 is communicated with cavity 21; Ejection mechanism for slow-release needles 1.

Wherein, the freezing needle can be chitin freezing needle, physiological saline freezing needle or antibiotic freezing needle, etc., and the appropriate freezing needle can be selected according to actual needs. It is worth mentioning that although the present invention focuses on acupoint embedding therapy and its application, it is obvious that the embodiments of the present invention can also be applied to other drug sustained-release injection treatments.

In this embodiment, the ejection mechanism 1 includes an elastic piece 11 connected to the tail end of the cavity 21 and a blocking piece 12 for blocking the elastic piece 11 , and the blocking piece 12 can move relative to the elastic piece 11 . Wherein, the elastic member 11 is initially in a compressed state and against the blocking sheet 12, and after the blocking sheet 12 is removed, the elastic member 11 resumes its deformation and ejects the freezing needle. Using the blocking piece 12 to block the elastic member 11 can make the deformation of the elastic member 11 controllable.

Obviously, the pop-up mechanism 1 formed by the combination of the blocking piece 12 and the elastic piece 11 may not be used. Other forms of ejection mechanism 1 can also achieve the inventive goal of the present invention. For example, we can also use a spring-type ejection mechanism 1 provided with a trigger button to replace the ejection mechanism 1 mentioned in this embodiment.

Specifically, the blocking sheet 12 runs through two opposite side walls of the casing 2 . In this way, by pushing the blocking piece 12 inward from one of the side walls, the blocking piece 12 can be extruded from the casing 2 , and then the deformation of the elastic member 11 can be restored.

In addition, in this embodiment, the slow-release needle set further includes a hub 3 detachably connected to the cannula 2, and a needle groove 31 communicating with the cavity 21 is provided in the hub 3, and the diameter of the needle groove 31 is from toward the cavity 21. The direction of the direction gradually decreases toward the direction away from the cavity 21 . The needle groove 31 in the hub 3 can be used to directly freeze and form the needle after the liquid of the frozen needle component is perfused. In this embodiment, the diameter of the connecting portion between the needle groove 31 and the cavity 21 is equal to the diameter of the cavity 21, which enables the freezing needle to enter the patient's body more smoothly.

An implementation scenario of this embodiment is as follows:

1. Fill the cannula 2 and the sleeve 3 with the liquid to be injected into the patient's body, such as chitin solution. Since the diameter of the cavity 21 is very small, the liquid in the casing 2 can be contained by the siphon principle.

2. Freeze the slow-release needle provided in this embodiment to obtain the slow-release needle containing the frozen needle.

3. Select Tianshu acupoint as the patient's operation site, and mark the acupoint with a marker pen. Position: It is located in the abdomen, at the center of the umbilical cord, 2 inches away from the anterior midline.

4. Routinely disinfect the operation site with alcohol, hold the cannula 2 with the index finger and thumb of the right hand, hold the needle of the frozen needle with the middle finger, and quickly penetrate the acupuncture point to a depth of about 15mm;

5. Pull out the blocking piece 12, the elastic member 11 pops out, and the freezing needle breaks away from the cannula 2;

6. The cannula 2 is pulled out, and the freezing needle is left deep in the patient's body.

Compared with the prior art, the embodiment of the present invention puts the freezing needle in the cannula 2, and when the cannula 2 is inserted into the human body, it is ejected by the pop-up mechanism 1, so that the freezing needle can stay in the human body for a relatively long time. deep position. Since only two steps of insertion and ejection are required during operation, the operation is simple and can even be operated by the patient himself, which is suitable for home health care use. Owing to only leaving the wound of sleeve pipe 2 diameter size on skin surface, so its wound is little, is difficult to cause wound infection.

The second embodiment of the present invention relates to a slow-release needle device, and the second embodiment is different from the first embodiment, the main difference is that in the first embodiment of the present invention: the blocking piece 12 runs through the cannula 2; and in the second embodiment of the present invention: as shown in FIG. The sleeve 2 pivots radially.

At this time, the blocking piece 12 can not only stagger the deformation direction of the elastic member 11 by rotation, but also return to its original position by rotation. Moreover, the blocking sheet 12 is not easy to fall off or be lost, which will enable the slow-release needle provided by the embodiment of the present invention to be reused many times, greatly reducing the cost and environmental pollution.

It is worth mentioning that if the slow-release needle is disposable, it can be made of plastic or glass to reduce costs. And if the slow-release needle is recyclable for many times, it is better to use stainless steel.

The third embodiment of the present invention relates to a sustained-release needle device. The third embodiment is an improvement of the first and second embodiments. The main improvement is that in the third embodiment of the present invention: the blocking sheet 12 is at least A part protrudes from the outer wall surface of the sleeve 2 , wherein the protruding part is used to move the blocking piece 12 .

Referring to FIG. 3 or FIG. 4 , at this time, the blocking sheet 12 can be operated without external tools. It greatly simplifies the difficulty of operation in actual use. It makes it easy for patients to inject themselves, which greatly reduces the burden on patients in seeking medical treatment.

The fourth embodiment of the present invention relates to a slow-release needle device. The fourth embodiment is different from the third embodiment. The main difference is that in the third embodiment of the present invention, at least a part of the blocking sheet 12 Protrude the outer wall surface of the sleeve 2, and use this protruding part to move the blocking piece 12; and in the fourth embodiment of the present invention: see Fig. 5 and Fig. 6, the slow-release needle includes a flexible belt 4 The thimble 5 connected with the outer wall of the sleeve 2 is used to push the blocking piece 12 .

Since the thimble 5 is bound by the lace, the thimble 5 in this embodiment is not easy to fall off, and it is convenient to use. In addition, compared with the technical solution in which the blocking piece 12 is partially protruding in the third embodiment, it is not easy to bend the protruding blocking piece 12 due to external force and make the slow-release needle fail.

It is worth mentioning that, in the above-mentioned first to fourth embodiments, the size of the blocking piece 12 shown in FIGS. 1 to 6 is similar to that of the elastic member 11 . However, in the process of actual use, since the sleeve 2 is relatively small, thickening treatment can also be performed on the sleeve 2 where the blocking piece 12 is located, and the radial cross-sectional area of the blocking piece 12 is much larger than the diameter of the elastic member 11. to the cross-sectional area.

The fifth embodiment of the present invention relates to a slow-release needle. The fifth embodiment is different from the first embodiment. The main difference is that, in the first embodiment of the present invention, the needle groove 31 is connected 21 is equal to the diameter of the cavity 21; and in the fifth embodiment of the present invention: as shown in FIG.

When the diameter of the joint between the needle groove 31 and the cavity 21 is larger than the diameter of the cavity 21, the freezing needle forms a javelin shape, and the barb formed at the needle can prevent the freezing needle from being taken out by the sleeve 2.

The sixth embodiment of the present invention relates to a slow-release needle device. The sixth embodiment is an improvement of the above-mentioned first to fifth embodiments. The main improvement is that, in the sixth embodiment of the present invention, see FIG. 8 As shown, the slow-release needle further includes a cleaning rod 6 , the diameter of which is smaller than that of the cavity 21 , and the cleaning rod 6 is used to reset the ejection mechanism 1 .

After the elastic member 11 is restored to deformation, use the cleaning rod 6 to insert into the cavity 21 and press the elastic member 11 until the elastic member 11 is in a compressed state, and then reset the blocking piece 12 to complete the reset of the slow-release needle .

In this embodiment, the cleaning rod 6 further includes a main body section 61 and a replacement section 62 located at the top of the main body section 61 , the thickness of the replacement section 62 is the same as that of the blocking piece 12 . When the blocking piece 12 is reset, the replacement section 62 is extruded, and the slow-release needle can be reset. Utilizing the replacement segment 62 can make the reset operation of the blocking piece 12 easier.

Those of ordinary skill in the art can understand that the above-mentioned embodiments are specific examples for realizing the present invention, and in practical applications, various changes can be made to it in form and details without departing from the spirit and spirit of the present invention. scope.
