Description

Puncture training teaching aid for venous indwelling needle

Technical Field

The utility model belongs to the technical field of teaching aids, and relates to a puncture training teaching aid for a venous indwelling needle.

Background

The venous indwelling needle consists of a stainless steel core, a soft outer sleeve and a plastic needle seat. When the cannula is sent into the blood vessel, the needle core is withdrawn, and only the soft cannula is left in the blood vessel for transfusion. The use of the intravenous needle can reduce pain of the patient caused by repeated venipuncture and reduce fear of the patient for multiple venipuncture. And after multiple venipuncture, patients are easy to become silted due to improper pressing, so that the subsequent venipuncture observation of medical staff is difficult.

Usually, during teaching, students need to simulate puncture with a teaching aid instead of directly adopting a real person to perform experiments, and the existing teaching aid is as in chinese patent application [ authorized bulletin number ]: CN210804940U discloses a keep somewhere needle puncture arm teaching model, including with the arm module of human arm shape similarity, rubber tube, elasticity sticky tape and a pair of perfusion device, the elasticity sticky tape is pasted on the surface of arm module, and the rubber block is arranged along the length direction of arm module, and the interlude of rubber tube links firmly between arm module and elasticity sticky tape, and a pair of perfusion device can dismantle with the both ends of rubber tube respectively and be connected.

The rubber tube is stuck on the arm module through the elastic adhesive tape, but the blood vessel of the human body can move left and right, and the skin of the arm also moves, so that the rubber tube is directly fixed, the teaching mould is not simulated enough, and after long-time teaching, a large number of injection holes are concentrated at the corresponding positions of the rubber tube and the arm module, so that the subsequent use cannot be realized, and the service life of the teaching mould is shortened.

Disclosure of Invention

The utility model aims at solving the problems in the prior art, and provides a puncture training teaching aid for a venous indwelling needle, which aims at solving the technical problems that: how to solve the problem of lower service life of the existing teaching aid.

The aim of the utility model can be achieved by the following technical scheme:

the utility model provides a vein keep somewhere needle puncture training teaching aid, includes arm module, rubber tube and the elasticity sticky tape similar with human arm shape, the rubber tube sets up along the length direction of arm module and pastes on the arm module through the elasticity sticky tape, its characterized in that, the cladding has the skin piece on the arm module, rubber tube and elasticity sticky tape all are located the below of skin layer, the skin piece can be moved about relative arm module, the connection can be dismantled at the both ends of skin piece.

Working principle: through pasting with the rubber tube with the elastic adhesive tape on the arm module, the cladding has the skin piece on the arm module again, the both ends of skin piece are detachable cover on the arm module this moment, the skin piece can be along the arm module left and right sides removal, because human arm has certain slippage when the puncture, through increasing the skin piece, make when the puncture, can furthest promote emulation degree, and because the syringe needle passes the skin piece earlier when training, and after a large amount of training, the skin piece can leave more pinholes on being close to rubber tube department, directly move the skin piece a distance back to the left or right, make the position that the skin piece is close to rubber tube department have the pinhole, thereby make the student can continue training use, the life of teaching aid has been promoted greatly.

In the venous indwelling needle puncture training teaching aid, the rubber tube is arranged on the arm module in a U-shaped mode, two ends of the rubber tube are located at one end of the arm module, and the two ends of the rubber tube can be connected with the perfusion device.

Through being the U-shaped setting with the rubber tube, can make the perfusion apparatus place in the one end of arm module, place such as transfusion bottle when the simulation people of as far as, and when the rubber tube of one side goes up the pinhole more, dismantle skin piece earlier, trade the rubber tube of opposite side again to the infusion side, thereby make the student promote the life of rubber tube when guaranteeing the emulation effect when using.

In the venous indwelling needle puncture training teaching aid, the rubber tube is provided with two parallel sections arranged along the length direction of the arm module and a connecting section which is arranged in an arc shape and connects the two parallel sections, the elastic adhesive tape is arranged along the width direction of the arm module and positions the two parallel sections on the arm module, and the parallel sections can move in the elastic adhesive tape.

Because the parallel section can move in the elastic adhesive tape, and when in actual puncture, the vein of a person can also move in a small amplitude, the design can simulate the vein of a human body as much as possible, and the simulation performance of the whole teaching aid is better.

In the venous indwelling needle puncture training teaching aid, two elastic adhesive tapes are arranged, and the two elastic adhesive tapes are distributed along the length direction of the arm module.

The elastic adhesive tape is only provided with two, so that the parallel sections of the same adhesive tape move more smoothly, the received resistance is smaller, the rubber tube can be stably attached to the arm module, and the use stability and the simulation of the training teaching aid are further improved.

In the venous indwelling needle puncture training teaching aid, magic tapes are arranged at two ends of the skin piece, and the two ends of the skin piece are attached through the magic tapes to form a ring shape.

Through the laminating of magic subsides for the loading and unloading of skin piece are more convenient, the adjustment of follow-up rubber tube and the adjustment of skin piece position of being convenient for promote the life of training teaching aid.

In the venous indwelling needle puncture training teaching aid, the two ends of the skin piece are connected with buckles, and the two ends of the skin piece are buckled through the buckles to form a ring shape.

Through the setting of buckle for the assembly of skin piece is convenient, the adjustment of follow-up rubber tube and the adjustment of skin piece position of being convenient for promotes the life of training teaching aid.

Compared with the prior art, the venous indwelling needle puncture training teaching aid has the advantages that: after a large amount of training, more needle eyes are left on the positions of the skin pieces, which are close to the rubber tube, and after the skin pieces are directly moved leftwards or rightwards for a certain distance, the positions of the skin pieces, which are close to the rubber tube, are free of the needle eyes, so that students can continue training and use, and the service life of the teaching aid is greatly prolonged; the skin has a certain slippage, and the rubber tube also has a certain slippage in the elastic rubber belt, so that the simulation degree can be improved to the greatest extent when the skin is punctured by adding the skin piece.
