Problems solved by technology

There are the following defects during puncture: 1. After the puncture needle is punctured, the indwelling sheath is placed on the chest wall to establish an air outlet channel, and the needle seat is not protected vertically on the chest wall of the human body.
2. Although it plays the role of exhaust, it is connected internally and externally. It can be used for short-term first aid, but when the wounded are left in place for a long time and cannot be transported in time, it needs to be connected to the manual valve to open and close.

Embodiment 1

[0017] Such as figure 1 , 2 Shown is the first tension pneumothorax puncture set, which is used during puncture. It includes a puncture needle 2 and an indwelling sheath 1. The puncture needle 2 is inserted into the indwelling sheath 1. The indwelling sheath 1 includes a sheath body 1-1 and a needle hub 1-2. One end of the sheath body 1-1 is connected to the needle The seat 1-2 is connected, the needle seat 1-2 is fitted with a fixed patch 3, and the fixed patch 3 is provided with a self-adhesive 4, and the self-adhesive 4 and the sheath body 1-1 are respectively arranged on the fixed patch 3 on the same side. The other end of the needle seat 1-2 is connected to the one-way check valve 7, the one-way check valve 7 includes a valve body 7-1, the valve body 7-1 is connected to the valve seat 7-2, and the valve seat 7-2 is connected to the check valve. The return piece 7-3 and the check piece 7-3 are arranged on the side of the valve seat 7-2 facing away from the needle seat 1...

Embodiment 2

[0019] Such as figure 2 , 3 As shown in . and 4, it is used during rapid infusion. The present invention mainly includes a puncture needle 2 and an indwelling sheath 1, the puncture needle 2 is inserted in the indwelling sheath 1, and the indwelling sheath 1 includes a sheath body 1-1 and a needle hub 1-2, one end of the sheath tube body 1-1 is connected to the needle hub 1-2, and a fixed patch 3 is fitted outside the needle hub 1-2, and the fixed patch 3 is provided with self-adhesive 4 and self-adhesive 4 It is respectively arranged on the same side of the fixing patch 3 as the sheath tube body 1-1.

Abstract

The invention discloses a tension pneumothorax puncture component, and relates to the field of medical equipment, in particular to a structure of a puncture needle component. The tension pneumothorax puncture component comprises a puncture needle and an indwelling sheathing canal, wherein the puncture needle is penetratingly arranged in the indwelling sheathing canal which comprises a sheathing canal body and a needle seat, one end of the sheathing canal is connected with the needle seat, a fixing paster is sleeved outside the needle seat in a matched manner, self-adhesive glue is arranged on the fixing paster, and the self-adhesive glue and the sheathing canal body are arranged on the same side of the fixing paster. During puncture, a puncture needle kit is taken out after a puncture needle protecting sleeve is opened, a glue face of the fixing paster is fixed towards the puncturing direction and the needle seat of the indwelling sheathing canal, the puncture needle punctures at an appointed thoracic cavity position after a skin is routinely disinfected and is pulled out after air exhaust is confirmed, and a protecting film of the glue face of the fixing paster is peeled off and fixed on a human body. Since the fixing paster for fixing the needle seat is added, the needle seat is fixed on the paster and adhered on the skin of a thoracic cavity via the self-adhesive glue, the functions of adhesive tape in dressing and fixing are realized, and the needle seat can be well fixed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the structure of a puncture needle assembly. Background technique [0002] The existing pneumothorax puncture assembly mainly includes a puncture needle and an indwelling sheath. The puncture needle is inserted into the indwelling sheath. The indwelling sheath includes a sheath body and a needle hub. One end of the sheath body is connected to the needle hub. There are following defects during puncture: 1. After the puncture needle is punctured, the indwelling sheath is placed on the chest wall to establish an air outlet channel, and the needle seat is vertically unprotected on the chest wall of the human body. 2. Although it plays the role of exhaust, it is connected internally and externally, and it can be used for short-term first aid, but when the wounded who are left for a long time cannot be transferred in time, it needs to be connected with the manual valve to open and cl...
