Problems solved by technology

[0002] Although there are many types of existing thoracentesis tube inserters, they have a single function and cannot cope with comprehensive rescue of multiple injuries and multiple site injuries in emergencies. Comprehensive rescue devices such as pressure suction, closed drainage, etc., including a thoracocentesis tube inserter, although it has been simplified to the first-line comprehensive rescue approach, but the invention does not solve the following problem: how can the Quickly solve the problems of ventilation, sputum suction and foreign body removal in upper airway obstruction and suffocation? How to solve the pain problem of cricothyroid membrane and thoracoabdominal wall incision and puncture in an emergency without anesthesia?

Embodiment Construction

[0016] figure 1 , figure 2 A schematic diagram of the structure of the present invention is shown. The bracket 5 is inserted on both sides of the top of the drainage tube 1. The two are detachable structures. The bracket 5 is the main carrier of the structure. 6. The blade 7 embedded in it is covered with a protective cap 8 on its outside, which acts like holding a sword handle; the lower end of the bracket 5 is inlaid with a puncture guide needle 3, and the puncture guide needle 3 is flat and sword-shaped as a whole, and its cross section is rhombus, and the four sides of the rhombus The corners are blunt and smooth, and the front end of the puncture guide needle 3 is a flat needle point 4 such as a "convex". The blind hole 2 matched with the "" shape makes the central part of the needle tip 4 protrude outside the blind hole 2, and the drooping shoulders 11 on both sides suddenly widen and are located in the blind hole 2. When the drainage tube 1 is inserted into the sword-...

Abstract

The invention relates to a sword-type coelocentesis catheterization device, and belongs to the field of medical aid. A guide needle of the device is sword-shaped and flat as a whole; the sword-shaped needlepoint is flat and convex; the convex tip protrudes out of a blind hole of a coelomic drainage tube, and dropped shoulders on the two sides are broadened and positioned in the blind hole; and the cross section of the sword-shaped guide needle is a rhombus, of which the four edges and corners are in blunt and smooth transition with one another. The device has the advantages of simple structure, convenient operation, small volume, light weight and strong emergency reaction, can provide thyrocricocentesis catheterization for aeration and aspiration of sputum and acute puncture catheterization of chest, abdomen and pelvic cavity for drainage at a top speed, meet the requirements of anatomical physiology and reduce the damage of tissues.

Description

technical field [0001] The invention relates to a puncture tube inserter, in particular to a sword-type body cavity puncture tube inserter suitable for on-site emergency cricothyroid membrane puncture tube placement, thoracic closed drainage, abdominal cavity and abscess cavity puncture drainage. Background technique [0002] Although there are many types of existing thoracentesis tube inserters, they have a single function and cannot cope with comprehensive rescue of multiple injuries and multiple site injuries in emergencies. Comprehensive rescue devices such as pressure suction, closed drainage, etc., including a thoracocentesis tube inserter, although it has been simplified to the first-line comprehensive rescue approach, but the invention does not solve the following problem: how can the Quickly solve the problems of ventilation, sputum suction, and foreign body removal in upper airway obstruction and suffocation? How to solve the pain problem of cricothyroid membrane ...
