Background

In the experiment operation of biological functions, rabbits are often used as experimental objects. In order to measure the rabbit arterial blood pressure, venous transfusion and other operations, the rabbit carotid artery and vein intubation is needed. The operation of inserting the jugular arteriovenous tube is often a key step of the experiment in the experiment operation.

The present chinese utility model patent, for example with patent number CN209301374U, discloses a novel experimental rabbit neck arteriovenous cannula, which is described basically as: the intubation tube head end movable device clamping strip is arranged on the intubation tube head end inherent device, the left end of the intubation tube body is connected to the right end of the intubation tube head end inherent device, and the intubation tube tail joint is connected to the tail end of the intubation tube body; the inherent device of the intubation head end comprises a line recess, a clamping recess and a plastic connecting band, wherein the number of the line recess is 3, the number of the line recess is 1 respectively on the upper surface and two side surfaces, the number of the clamping recess is 9, the number of the clamping recess is 3 respectively on the upper surface and two side surfaces, the length, the width and the depth of the line recess and the clamping recess are the same, and are respectively 2mm, 1mm and 0.25mm, the plastic connecting band is designed into an inverted U shape, and the plastic connecting band is made of plastic materials with toughness and durability and can be turned over; the inserting tube head end movable device clamping strip comprises a clamping protrusion and a wire groove.

Based on the description of the patent, it can be seen that when the arteriovenous intubation tube in similar patent is used, the arteriovenous intubation tube is often fixed at the arteriovenous incision of the neck of the rabbit by means of the needle-thread matching fixing component, so that the arteriovenous intubation tube and the arteriovenous neck of the rabbit are prevented from slipping.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a fixed subassembly of biological function experiment rabbit neck arteriovenous intubate, when using with the arteriovenous intubate that the solution is similar to that the above-mentioned current patent structure provided, often need fix the arteriovenous intubate in rabbit neck arteriovenous incision department with the help of the fixed subassembly of needle line cooperation, avoid arteriovenous intubate and rabbit neck arteriovenous slippage, this scheme is high to the manual technical requirement of needle line, practice operating personnel who is not skilled to the manual technique of part needle line, very easily lead to actuating between vein intubate and the rabbit neck arteriovenous to take place to drop, if do not take timely effectual measure, can influence the accuracy of experimental result lightly, the person of heaviness leads to the rabbit because of the too much dead problem of blood loss.

The utility model relates to a purpose and efficiency of fixed subassembly of biological function experiment rabbit neck sound arteries and veins intubate are reached by following specific technological means:

a fixing component of an arteriovenous intubation of a neck of a rabbit for biological function experiment comprises an intubation; the periphery of the insertion tube is connected with a pulling block in a sliding manner; the periphery of the intubation is sleeved with an independently detachable fixed sleeve, and the fixed sleeve is of a conical sleeve structure; the fixed sleeve and the pull block are detachably connected together through a snap.

Furthermore, T-shaped sliding grooves distributed in an annular array are formed in the periphery of the insertion pipe.

Furthermore, the pulling block is of a circular ring plate-shaped structure, and T-shaped sliding blocks distributed in an annular array are machined on the inner ring of the pulling block.

Furthermore, round hole-shaped buckling holes distributed in an annular array are formed in the pulling block.

Furthermore, the larger end of the opening of the fixed sleeve is provided with fastening heads distributed in an annular array.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model is provided with a fixed sleeve which can sleeve and lock the rabbit neck artery and vein and the intubation tube which are spliced together, and has simple structure and convenient operation;

the utility model is provided with a pulling block, after the experiment is finished, a user can pull the fixed sleeve in an auxiliary way through the fixed pulling block to disassemble the fixed sleeve, and secondary extrusion damage to the artery and vein of the rabbit neck is avoided when the fixed sleeve is directly pinched, pulled and disassembled;

the series of structures effectively solve the problem that the artery and vein intubation and the rabbit neck artery and vein are unstable to be fixed and to fall off due to the fact that an operator is not skilled in needle thread manual technology, and use convenience and practicability of the fixed assembly are improved.
