Abstract

The utility model provides a pen type multifunctional thoracic decompression and ventilation drainage puncture needle which comprises a barrel (1), a decompression and ventilation puncture needle and a drainage cannula, wherein the decompression and ventilation puncture needle consists of a decompression and ventilation puncture needle seat (2b) and a needle body (2a), the drainage cannula consists of a drainage cannula seat (3b) and a cannula body (3a), the decompression and ventilation puncture needle is positioned in the drainage cannula, and the decompression and ventilation puncture needle and the drainage cannula are assembled into a whole to be put in the barrel (1). A one-way valve chamber is arranged on the decompression and ventilation puncture needle seat, and a valvular one-way valve is arranged in the one-way valve chamber. The front part of the decompression and ventilation puncture needle seat is inserted into the central hole of the drainage cannula seat. The pen type multifunctional thoracic decompression and ventilation drainage puncture needle adopts barrel-type packaging, is convenient to carry, has good damage resistance, can be repeatedly disinfected, can complete thoracic decompression and ventilation at one time, has a drainage function, and is very suitable for quickly rescuing the wounded under the condition of field operations.

Description

Pen type thoracic cavity decompression exhaust drain puncture needle

Technical field

This utility model belongs to technical field of medical instruments, specifically, relates to the aerofluxus of a kind of thoracic cavity, drain puncture needle.

Background technology

In existing thoracic surgery; Thoracic cavity aerofluxus and chest drainage are to accomplish with thoracic cavity aerofluxus puncture needle and chest drainage puncture needle respectively; Can not disposable completion thoracic cavity decompression exhaust and drain, that be because thoracic cavity aerofluxus puncture needle and chest drainage puncture needle be independently, the apparatus of function singleness.On packing, existing thoracic cavity aerofluxus puncture needle and chest drainage puncture needle adopt carton box or plastic bag packaging more, take inconvenience, are difficult for directly sterilization, and anti-damage property is relatively poor.

The utility model content

The purpose of this utility model provides a kind of have the thoracic cavity decompression exhaust of completion and drain function; Easy to carry; Can sterilize repeatedly, anti-damage property is good, can guarantee under field condition the wounded are realized the pen type multifunctional thoracic cavity decompression exhaust drain puncture needle of quick thoracic cavity decompression exhaust and drain.

For this reason; The pen type multifunctional thoracic cavity decompression exhaust drain puncture needle of this utility model; Include the shaft of a writing brush, decompression exhaust puncture needle and drain sleeve pipe, the decompression exhaust puncture needle is made up of decompression exhaust puncture needle base and needle body, and the drain sleeve pipe is made up of drain sleeve pipe base and union body; Plug-inly between decompression exhaust puncture needle and the drain sleeve pipe do as a whole being positioned in the shaft of a writing brush, the needle body of decompression exhaust puncture needle is positioned in the telescopic union body of drain.

During use, open the shaft of a writing brush, take out as a decompression exhaust puncture needle and drain sleeve pipe whole; Carry out the thoracentesis operation; When aerothorax was pressed greater than ambient pressure, pneumatosis excreted through the check valve on the decompression exhaust puncture needle, when intrathoracic pressure power and ambient pressure balance; Closed check valve on the decompression exhaust puncture needle, ambient atmos gets in the thoracic cavity in the resistance.When there is hydrops in the thoracic cavity, extract the decompression exhaust puncture needle, stay the drain sleeve pipe in body, use syringe to extract hydrops in the thoracic cavity out, or connect the drainage bag drain.

Decompression exhaust puncture needle base is provided with the Non-return air valve chamber, and Non-return air valve is indoor to have valve formula check valve; Insert in the centre bore of drain sleeve pipe base the front portion of decompression exhaust pin base.Decompression exhaust pin and drain sleeve pipe are assembled together like this, use with dismounting all very convenient, extract the decompression exhaust puncture needle after, the drain sleeve pipe is as the passage of extraction and drain hydrothorax, thus disposable completion thoracic cavity decompression exhaust and drain function.

This utility model adopts shaft of a writing brush formula packing, and is easy to carry, and anti-damage property is good, can sterilize repeatedly, and ability disposable completion thoracic cavity decompression exhaust and drain function are very suitable for suing and labouring fast to the wounded under the field condition.

The specific embodiment

Through specific embodiment this utility model is elaborated below.

Extremely shown in Figure 4 like Fig. 1; The pen type multifunctional thoracic cavity decompression exhaust drain puncture needle of this utility model has the shaft of a writing brush 1, decompression exhaust puncture needle and drain sleeve pipe; The decompression exhaust puncture needle is made up of decompression exhaust puncture needle base 2b and needle body 2a, and the drain sleeve pipe is made up of drain sleeve pipe base 3b and union body 3a, plug-inly between decompression exhaust puncture needle and the drain sleeve pipe does as a whole being positioned in the shaft of a writing brush 1; The needle body 2a of decompression exhaust puncture needle is positioned in the telescopic union body 3a of drain; The shaft of a writing brush 1 is two parts fabricated structure, is similar to the shaft of a writing brush of pen, can be hung in the coat pocket.

Participate in Fig. 2, Fig. 4, decompression exhaust puncture needle base 2b is provided with Non-return air valve chamber 4, and valve formula check valve 5 is arranged in the Non-return air valve chamber 4, and needle body 2a is a stainless steel material, and decompression exhaust puncture needle base 2b is cylindrical, and front end has collar.

Referring to Fig. 1, Fig. 3, the front portion of decompression exhaust puncture needle base 2b is that collar inserts in the centre bore 6 of drain sleeve pipe base 3b, and union body 3a is a macromolecule transparent material, and drain sleeve pipe base 3b is cylindric, and its outer peripheral face has an annular groove.

During use, open the shaft of a writing brush 1, take out and make as a whole decompression exhaust puncture needle 2 and drain sleeve pipe 3; Carry out the thoracentesis operation; When aerothorax was pressed greater than ambient pressure, pneumatosis excreted through the check valve on the decompression exhaust puncture needle 2, when intrathoracic pressure power and ambient pressure balance; Check valve 5 on the decompression exhaust puncture needle is closed, and ambient atmos gets in the thoracic cavity in the resistance.When there is hydrops in the thoracic cavity, extract decompression exhaust puncture needle 2, stay drain sleeve pipe 3 in body, use syringe to extract hydrops in the thoracic cavity out, or connect the drainage bag drain, thereby accomplish thoracic cavity decompression exhaust and drain once.
