Lumbar cistern drainage tube stealthy indwelling guide device

Abstract

The invention discloses a lumbar cistern drainage tube stealthy indwelling guide device. The device solves the problem that drainage tube indwelling has short crouchonecm and cannot be maintained fora long time in the prior art, and has the advantages that a lumbar puncture needle is convenient to withdraw, and the crouchonecm of a drainage tube in subcutaneous tissue can be lengthened. Accordingto the technical scheme, the lumbar cistern drainage tube stealthy indwelling guide device includes an outer sleeve needle, a first member and a second member, wherein one end of the outer sleeve needle is sharp and facilitates puncture, and the outer sleeve needle is internally provided with a tube cavity and is provided with a side seam that is perpendicular to the tube cavity; one end of the first member is provided with a hook, and the hook can hook the lumbar puncture needle and / or the lumbar cistern drainage tube; the second member cooperates with the first member, the two members can enter the tube cavity together, and one end of the second member can be abutted against the inner wall of the tube cavity.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a submerged indwelling guide device for a lumbar drainage tube. Background technique [0002] At present, there are two methods of clinically indwelling the lumbar drainage tube: 1. Direct puncture: After the lumbar puncture needle is successfully punctured into the lumbar pool, the needle core is withdrawn, and the drainage tube is inserted through the needle cavity of the puncture needle. This method is currently the most widely used general method at home and abroad. The operation is simple and convenient, but the disadvantage is that there is no lateral sneak distance. 2. Other methods: a. On the basis of successful direct puncture and catheter placement, make a skin incision next to the original skin puncture hole, use vascular forceps to poke out the subcutaneous tunnel, and then lead out the tail section of the drainage tube at the original puncture hole through the incisi...

AI Technical Summary

Problems solved by technology

This method looks simple to operate and has a stealth effect from the outside. In fact, because the curved and shaped puncture needle can only poke through the original puncture hole, there are four obvious disadvantages: easy to damage the drainage tube, insufficient skin coverage at the puncture hole and even lead to The drainage tube is partially exposed, the overall sneak is too shallow and the sneak distance is limited

Because the nurses often push the skin and subcutaneous soft tissue to move to a certain extent before turning the patient's body as a whole when assisting to turn over. As a result, the drainage tube in the body is loosened due to tension or relative movement between the drainage tube and the surrounding tissue due to traction. Even some parts of the drainage tube "sway" in the subcutaneous soft tissue, which is prone to secondary exudation and retrograde infection; in addition, for patients who are obviously emaciated, due to the lack of sufficient fat layer protection between the skin and the lumbar supraspinous ligament, the drainage tube is very likely to occur Loosening and leakage of cerebrospinal fluid along the space around the drainage tube, even in the process of conventional direct puncture catheterization, cerebrospinal fluid leaks through the tube, even if the skin around the puncture hole is sutured, it is still easy to leak

Although emaciated patients are not prone to "movement" of the drainage tube in the body when turning over, they are also prone to retrograde infection due to the short barrier distance and easy seepage

Therefore, it is more difficult to maintain the lumbar drainage tube for significantly obese patients and significantly emaciated patients.

[0004] The above-mentioned methods are obviously not ideal for the indwelling effect of the lumbar drainage tube: the maintenance of the lumbar drainage tube is difficult and the maintenance time is short, which not only increases the difficulty of nursing, but also requires frequent wound dressing changes or even re-puncture the tube to increase the medical workload. It also increases material loss, economic burden and patient suffering

The key point is that the defects of the traditional indwelling method make the drainage tube easy to loosen, leak and even cause retrograde infection. As a result, the maintenance time of drainage is shortened and the risk of retrograde infection is increased, which ultimately affects the treatment effect and even causes new infections.

For those with poor skin conditions on the lower back, such as skin inflammation and scars near the puncture area, the difficulty of avoiding them also seriously affects the implementation of these methods of indwelling lumbar drainage tubes.
