Description

A human organ perfusion tube

technical field

The invention relates to the technical field of medical equipment, more specifically, to a human organ perfusion tube.

Background technique

At present, organ transplantation is the best way to treat patients with organ failure (such as liver and kidney failure, etc.).

Because isolated organs tend to lose viability within a short period of time at normal temperatures (warm ischemia), cryopreservation of isolated organs is required (cold ischemia). The method is to quickly lavage the organ with the organ lavage fluid at a temperature of 0-4°C, and then place the organ in a container containing the lavage fluid at a temperature of 2-4°C for preservation.

At present, there is no human organ perfusion tube specially used for organ transplantation. When organ perfusion is performed, a urinary catheter or other drainage tubes are usually used to modify the perfusion tube. Although the perfusion tubes modified by themselves can complete the perfusion operation, due to the different modification methods of the manufacturers, the perfusion tubes are quite different and the specifications are not uniform, which not only affects the control of perfusion speed and perfusion time during perfusion operations, but also affects perfusion. However, there are also problems such as complicated operation and time-consuming.

Detailed ways

The embodiment of the invention discloses a human organ perfusion tube, which improves and enhances the perfusion operation effect and simplifies the perfusion operation.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to FIG. 1 , the human organ perfusion tube provided by the present invention includes a tube body 1 on which an air bag 10 , a water outlet hole 11 , a snap ring 12 , an outer port 13 of the air bag and a water inlet hole 14 are arranged.

Wherein, the air bag 10, the water outlet hole 11 and the snap ring 12 are arranged successively along the direction from the head of the pipe body 1 to its tail; The outer port 13 is connected, and the water outlet hole 11 is connected with the water inlet hole 14 .

The human organ perfusion tube provided by the present invention is mainly used for perfusion in surgical operations for harvesting organs from cadaveric transplant donors. When in use, place the front end of the human organ perfusion tube on the proximal end of the organ artery to be perfused in the abdominal aorta; then inflate the airbag 10 to block the proximal end of the abdominal aorta to the organ to be perfused; Fix the blood vessel and the clasp 12 outside the blood vessel corresponding to the clasp 12 of the perfusion tube, so that the blood vessel and the clasp 12 are tightly bonded and in a sealed state to prevent the perfusate from leaking out of the blood vessel; finally inject the perfusate through the water inlet 14 , implement the perfusion operation.

Compared with the existing perfusion tube obtained through transformation, the perfusion tube provided by the present invention has a unified structure, and there is no difference between perfusion tubes of the same specification, so that the operator can control the perfusion speed and time more accurately, Therefore, the effect of the perfusion operation is improved; at the same time, the same structure is conducive to improving the operator's proficiency in using the perfusion tube, and the purpose of simplifying the perfusion operation is realized.

Preferably, in the human organ perfusion tube provided in the above embodiments, the head of the tube body 1 is a solid cone. Since the blood vessels in different parts of the human body have different curved shapes, the perfusion tubes of human organs must be made of relatively soft materials to produce sufficient deformation to adapt to the direction of blood vessels. However, when the perfusion tubes of human organs are soft, when a little force is applied That is, it deforms and it is more difficult to penetrate it into the blood vessel. By setting the head of the tube body 1 as a solid cone, this problem is effectively solved: the solid part can enhance the hardness of the perfusion tube of human organs and avoid the difficulty of tube penetration caused by force deformation; the shape of the cone can play a role The guiding function further assists the operation of passing through the pipe.

Those skilled in the art can understand that since each organ of the human body has a different structure, if different human organ perfusion tubes are made for different organs, the size and relative position of each component on the human organ perfusion tube will also change accordingly. A preferred size of the perfusion tube for human organs is described below as an example, but it should be understood that the perfusion tube for human organs provided by the present invention is not limited to the size in the following examples.

In the human organ perfusion tube provided by an embodiment of the present invention, the distance between the air bag 10 and the head of the tube body 1 is 1 cm, the length of the air bag 10 is 1.5 cm, the distance between the water outlet hole 11 and the air bag 10 is 1 cm, and the snap ring 12 is 15 centimetres, and the length of snap ring 12 is 1.5 centimetres.

In the human organ perfusion tube provided in another embodiment of the present invention, a plurality of water outlet holes 11 are provided. By providing a plurality of water outlet holes 11, the injection speed of the perfusate can be increased during perfusion. Preferably, as shown in FIG. 2 , three water outlet holes 11 with a diameter of 0.5 cm are arranged spirally along the axial direction of the pipe body 1 at an interval of 0.8 cm.

Further, in order to facilitate the fixing of the perfusion tube for human organs, the snap ring 12 is slidably sleeved on the tube body 1 . It is conceivable that by setting the clasp 12 as a slidable structure, the operator can flexibly adjust the position of the clasp 12 on the tube body 1 according to actual needs, thereby reducing the difficulty of implanting the perfusion tube of human organs, reducing the At the same time, since the pipe body 1 and the snap ring 12 need to be sealed and connected, the pipe body 1 and the snap ring 12 should be an interference fit, or use elastic materials, such as medical rubber, etc. The snap ring 12 is made, and the snap ring 12 can be tightened on the pipe body 1 by its own elasticity.

Furthermore, in order to simplify the connection between the human organ perfusion tube and the human blood vessel, so that the blood vessel and the snap ring 12 are tightly sealed, the human organ perfusion tube provided by another embodiment of the present invention also includes a snap ring clip 2 . Please refer to FIG. 3 , the structure of the snap ring clip 2 is similar to that of common clips, and consists of two left and right half snap ring clips 20 connected by hinges. In particular, an annular jaw 21 is arranged at the head of the snap ring clip. The inner diameter of the annular jaw 21 is not smaller than the diameter of the snap ring 12 . When fixing, it is only necessary to clamp the snap ring clip 2 on the blood vessel at the position corresponding to the snap ring 12. Since the inner diameter of the jaws 21 is not smaller than the diameter of the snap ring 12, the blood vessel can be clamped on the snap ring 12. outside, and make the two close to each other.

Preferably, the snap ring clamp 2 further includes a torsion spring or buckle to keep it in a clamped state.

Each embodiment in this specification is described in a progressive manner, each embodiment focuses on the difference from other embodiments, and the same and similar parts of each embodiment can be referred to each other.

The above description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
