Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a screwing type efficient hemostatic vascular access.
Background
Long term vascular access is a common medical procedure used in a variety of medical contexts, and the use of peripheral blood vessels to access the cardiovascular system has been developed in recent years to avoid invasive open chest surgery.
Dacron grafts are commonly used in long term vascular access and remain in the patient for up to several days, and these grafts are basically used by suturing to the vessel at one end and closing the other end with a different method to ensure hemostasis. Once blood has entered the graft, the porous dacron mesh is permeated and blocked by blood, a common treatment is to use a regular medical silicone plug, secured with ordinary medical sutures to ensure hemostasis, and grafts made of other materials such as silicone may also be used.
Considering that these procedures involve one of the main vascular vessels, bleeding is a major concern; thus, hemostasis is an important aspect of these procedures, and any failure to stop bleeding at any time during or after insertion of the device can result in substantial blood loss and even patient death, with existing vascular one-way valves being essentially blocked with rubber sheets, having poor hemostatic effects, and being prone to reverse leakage.
Disclosure of Invention

And triangular hollow parts are arranged on the membrane rigid body at intervals along the radial direction of the membrane rigid body, so that the medical device is allowed to be inserted through the membrane rigid body and the membrane flexible body in sequence, and blood is prevented from penetrating from one side of the membrane flexible body to the side of the membrane rigid body.
In a further aspect, the membrane flexible body has a central bore for passage of a medical device, and a plurality of slits arranged to extend radially to allow the central bore to expand to accommodate passage of the medical device.
In a further technical scheme, the slits on the membrane flexible bodies are staggered with the joints between adjacent membrane rigid bodies.
In a further technical scheme, 3-8 membrane rigid bodies are arranged.
In a further aspect, the artificial blood vessel is screwed with the hemostatic valve.

And triangular hollow parts 24 are arranged on the membrane rigid body 23 at intervals along the radial direction of the membrane rigid body, so that the medical device is allowed to be inserted through the membrane rigid body 23 and the membrane flexible body 25 in sequence, and blood is prevented from penetrating from one side of the membrane flexible body 25 to the side of the membrane rigid body 23.
Referring to fig. 2, the artificial blood vessel 10 of the present invention is a soft tube made of a medical material commonly used at present, and has a first port 11 and a second port 12; wherein, the port one 11 is used for being inserted into a blood vessel to carry out suture interface, and the port two 12 is arranged outwards.
In the present invention, the membrane rigid body 23 has the following working principle: due to the triangular hollow portion 24, the membrane rigid body 23 has unidirectional conductivity, that is, when the medical device passes from the membrane rigid body 23 side to the membrane flexible body 25 side, the triangular hollow portion 24 can be extruded to bend the membrane rigid body 23, so that the medical device can pass through; when blood on the side of the membrane flexible body 25 adjacent to the artificial blood vessel 10 is to pass through, the pressure generated by the membrane flexible body cannot cause the triangular hollow part 24 to be extruded, that is, the membrane rigid body 23 cannot bend at the moment, so that a reliable hemostatic effect is achieved.
In the technical scheme provided by the invention, the hemostatic effect is ensured by arranging the matching of the membrane flexible body 25 and the membrane rigid body 23 in the tubular shell of the hemostatic valve 20.
Further, in the present invention, the membrane flexible body 25 has a central hole for the passage of a medical device, and a plurality of slits arranged to extend in a radial direction to allow the central hole to be enlarged to accommodate the passage of the medical device. As shown in fig. 3 and 4, the flexible membrane body 25 of the present invention extends inward from the inner wall of the tubular housing, and has a central hole and a plurality of slits connected to the central hole and extending in the radial direction, and when the medical device passes through, the central hole is pressed and enlarged, and the hole edge of the central hole is closely attached to the outer surface of the medical device, thereby preventing the exudation of blood.
In the present invention, in order to further secure the hemostatic effect, the slit on the membrane flexible body 25 is offset from the seam between the adjacent membrane rigid bodies 23, so that blood is effectively prevented from penetrating to one side of the membrane rigid bodies 23 through the slit on the membrane flexible body 25 and leaking out through the seam between the adjacent membrane rigid bodies 23.
In the present invention, the round surface is formed by splicing the plurality of membrane rigid bodies 23, and the triangular hollow portion 24 provided in the membrane rigid body 23 provides a pressing space for stably inserting the medical device while ensuring the hemostatic effect when the medical device is inserted through the center position thereof by splicing the plurality of membrane rigid bodies 23. In particular, the membrane rigid bodies 23 are provided with 3-8, for example as can be seen in fig. 3, comprising 8 membrane rigid bodies 23.
In the present invention, the artificial blood vessel 10 and the hemostatic valve 20 are connected by screw threads. The hemostatic valve 20 is connected with the artificial blood vessel 10 through threads, so that the hemostatic valve 20 is connected with the artificial blood vessel 10 more stably.
In a further embodiment, the artificial blood vessel 10 is provided with a connecting section 15 arranged coaxially at one end adjacent to the hemostatic valve 20, and a first tearing seam 13 is arranged at the connecting position of the connecting section 15 and the artificial blood vessel 10 to allow the connecting section 15 to be separated from the artificial blood vessel 10;

In the present invention, the tubular housing is provided with a third tear seam 26 extending along its length to allow separation into at least two parts.
In the present invention, at least two handholds 22 are provided on the outer wall of the tubular housing for an operator to tear and separate the tubular housing into at least two parts.
Taking a heart pump as the medical device as an example, when the hemostatic vascular access provided by the invention is used, the hemostatic valve 20 is firstly in threaded connection with the artificial blood vessel 10 with the connecting section 15, then the port I11 of the artificial blood vessel 10 is sutured with the blood vessel, and the artificial blood vessel 10 is internally provided with blood but prevented by the membrane flexible body 25 and the membrane rigid body 23;
The medical staff inserts the heart pump from diaphragm rigid body 23 one side, and the triangle hollow 24 in the diaphragm rigid body 23 provides the space and is extruded, and the diaphragm rigid body 23 takes place to bend and supplies heart pump to insert, and diaphragm rigid body 23 and diaphragm flexible body 25 all laminate on the surface of heart pump, guarantees that when heart pump removes, and blood can not flow, and after the heart pump got into the blood vessel and accomplished, bind together vascular prosthesis 10 and heart pump through the string, then separate hemostatic valve 20 along third tear seam 26 through hand-held part 22, then separate connecting section 15 along second tear seam 14 again, and two parts of connecting section 15 are separated from vascular prosthesis 10 along first tear seam 13 again.
The foregoing has outlined and described the basic principles, main features and features of the present invention.
