Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to an organ adapter pipe capable of automatically separating air bubbles. BACKGROUND

[0002] In the conventional scheme, see Figure 1 , a perfusion system is usually connected to the arterial wall of an organ to be repaired using a T-shaped adapter pipe, which is usually connected to a perfusion circulation loop at a first luer head A1, connected to the arterial wall of the organ at a connection end B, and provided with a perfusion gas outlet second luer head A2 at the rear of the adapter pipe. The perfusion liquid flows in from the first luer head A1 inlet, and the perfusion gas is pushed out from the rear gas outlet second luer head A2 under the pressure in the pipeline. When the air in the adapter pipe is completely discharged, the gas outlet second luer head A2 is closed by a luer plug seal cover in a manual manner, the perfusion liquid flows from the connection end B into the organ, and the perfusion mode is entered.

[0003] In US9642625B2, a perfusion system is usually connected to the arterial wall of an organ to be repaired using a repeatable open adapter pipe, which is connected in a clamped manner. The adapter pipe is usually provided with a perfusion inlet at the front and a perfusion gas outlet at the rear. The adapter pipe has two layers, and a passage is formed at the bottom for clamping and sealing connection with the organ to be repaired. The perfusion liquid flows in from the inlet, and the perfusion gas is pushed out from the rear gas outlet under the pressure in the pipeline. When the air in the adapter pipe is completely discharged, the gas outlet is closed by a seal cover in a manual manner, and the perfusion mode is entered.

[0004] The existing problems are: (1) In the conventional scheme and US9642625B2 scheme, since the gas outlet of the adapter pipe is in the axial direction, it is difficult to avoid that all the gas at the top of the cavity is discharged in time and fully in the initial state of perfusion. Small air bubbles remaining at the top of the adapter pipe have the risk of forming embolism to the organ during subsequent perfusion; (2) The US9642625B2 scheme needs to be repeatedly opened and closed by manual operation, which is complex and affects the timeliness of organ perfusion repair, and also increases the risk of organ contamination; (3) In the conventional scheme, the organ is usually fixed on the adapter pipe by lacing with a lacing wire. The operation is complex, and the lacing wire is too tight, which can easily damage the organ tissue and affect the subsequent transplantation surgery. If the lacing wire is too loose, the organ can easily fall off during perfusion and cannot be effectively perfused. Moreover, the lacing wire directly acts on the blood vessels of the organ, which can cause irreversible damage to the organ. SUMMARY

[0005] The organ adapter pipe of the application can automatically separate bubbles, is convenient to operate, reliable in connection, and can automatically remove bubbles.

[0006] In order to achieve the above-mentioned purpose, the application adopts the following technical scheme: an organ adapter pipe capable of automatically separating bubbles, characterized in that the organ adapter pipe comprises a base support, a through hole is arranged on the base support, and a flexible gasket is arranged at the through hole;

[0007] A flip cover is arranged on the base support, one side of the flip cover is rotatably connected to one side of the base support, a water-blocking and air-permeable film mounting port is arranged on the flip cover, a water-blocking and air-permeable film is arranged at the water-blocking and air-permeable film mounting port, a pipe leading into the flip cover is arranged on the flip cover, a clamping end surface is arranged at the inner bottom of the flip cover, and the clamping end surface and the flexible gasket clamp the renal artery wall to perform perfusion after the flip cover and the base support are closed.

[0008] Further, a flexible gasket mounting groove for mounting the flexible gasket is arranged on the base support.

[0009] Further, a clamping opening is arranged on the other side of the base support, a clamping block is arranged on the other side of the flip cover, and the clamping block and the clamping opening are matched.

[0010] Further, a shaft portion is arranged on one side of the flip cover, and a hanging ear is arranged on one side of the base support, the hanging ear and the shaft portion being rotatably connected.

The bayonet and the clamping block can improve the stability of the bottom support and the flip cover after being closed.

[0033] In the embodiment, one side of the flip cover 21 is provided with a shaft part 216, and one side of the bottom support 11 is provided with a hanging ear 114, which are rotatably connected.

[0034] In the embodiment, a support is further included, which has a support main body 31, the support main body 31 is provided with a transverse mounting groove 311, and the top of the support main body 31 is provided with a top notch 312, and the closed bottom support and flip cover are mounted at the transverse mounting groove.

[0035] The organ connection is sealed: the upper surface of the organ artery wall and the clamping end surface of the flip cover form a seal under pressure, and the lower surface forms a seal with the flexible sealing gasket, which is an elastomer material (including but not limited to rubber material), so as to adapt to the differences in organ artery walls of different individuals and not to damage the artery walls of the organ.

[0036] Automatic exhaust: under the initial condition of perfusion, there is a small amount of air in the internal of the adapter pipe and the end of the perfusion loop, under the action of pump pressure, the liquid in the perfusion loop flows into the cavity formed by the adapter pipe and the organ, and under the action of gravity, the liquid gradually fills the entire cavity from low to high, at the same time, under the action of buoyancy, the air at the end of the circulating pipeline and the end of the adapter pipe gradually rises, flows through the water-blocking and air-permeable membrane of the adapter pipe, and is completely exhausted until the liquid fills the cavity of the adapter pipe; thus, the automatic exhaust function of the circulating pipeline and the end is completed.

[0037] The perfused organ is connected with the adapter pipe (the artery wall 10a of the organ 10 passes through the through hole of the bottom support), the pretreated artery wall of the organ is clamped between the flip cover and the bottom support, forming a sealed cavity (the perfusion liquid flows into the sealed cavity formed by the bottom support, the flip cover and the organ from the adapter pipe), and the perfusion liquid in the circulating system can enter the sealed cavity through the adapter pipe of the flip cover under the action of pump pressure Figure 4The middle arrow F represents the perfusion liquid flow direction, the artery wall upper surface forms a seal with the flip inner wall, and the artery wall lower surface forms a seal with the flexible sealing pad, so that under the action of the pump pressure, the perfusion liquid will further flow through the blood vessels into the internal blood vessels of the organ (the perfusion liquid flows out of the organ veins).

[0041] The tray can accommodate the organ to protect the organ (limiting and covering), the sliding clamping buckle can be adjusted by sliding in the sliding clamping groove, and the appropriate position is selected according to the length of the artery of different organs (after adjustment, the sliding clamping buckle is clamped on the sliding clamping groove). The liquid in the tray can flow out of the overflow port at the top of the tray.

[0042] It should be noted that after the first disc body and the second disc body are closed, the stable closing mode can refer to the prior art, including but not limited to the following forms: the first mode can be to make the two disc bodies (trays) stably closed by rope winding and binding; the second mode can be to stably close the first disc body and the second disc body (tray) by arranging a reverse U-shaped clamp at the top of the tray; and the third mode can be to put the tray between two oppositely arranged clamping walls in the accommodating cavity of the organ, so that the tray is clamped between the two clamping walls to achieve stable closing.
