Abstract

The utility model discloses a thorthorax closed drainage device comprising a liquid trap, a valva one-way valve, a drainage bag, a clamp valve and a matched puncture needle and a drainage tube; wherein, the liquid trap is a bilayer structure; a funnel liquid trap in an upper layer is sleeved in to the liquid trap in a lower layer, and both are combined as a whole and are sealed. An inlet pipe is arranged on the liquid trap in the upper layer and is matched with a C-shaped thorax puncture needle and the drainage tube with a fixing lug; the drainage tube is positioned into the C-shaped thorax puncture needle and is sleeved on the inlet pipe; the liquid trap in the lower layer has an outlet pipe and a negative pressure ball sucking interface; the liquid trap in the upper layer is connected with the liquid trap in the lower layer through the valva one-way valve; the liquid trap in the lower layer is connected with the valva one-way valve in the drainage bag; the clamp valve is arranged on the drainage bag. The thorthorax closed drainage device can prevent the retrograde infection completely because the whole system works under the fully enclosed condition, so that the utility model is applicable to the complicated field operations and the clinical works, and is safer and more reliable when matching with a water-sealed bottle.

Description

A kind of pleural cavity closed drainage device

This utility model relates to medical wound drainage device technical field and is applied to thoracic trauma, especially perforating wound.

Existing pleural cavity closed drainage device, be at the long otch of chest corresponding site work-2CM, cut skin and subcutaneous tissue, separate thoracic wall muscle, wear pleura with the pincers spine with the curved hemostat passivity, if promptly proving, the gas inlet and outlet wound reached the thoracic cavity, insert backward downwards, conduit enters length and generally is no more than 7CM, performs earlier mark on pipe, managed deeply or shallow excessively in order to avoid put, connect the drainage bottle of containing a certain amount of normal saline then.Its deficiency is under the complex environment of battlefield in the open air: method of intubation requires high process complexity; Get before the inlet pipe and on pipe, perform mark earlier, guarantee the inlet pipe degree of depth; The fixing of drainage tube also is a great problem for the wounded that need shift; Drainage bottle must inject a certain amount of normal saline before use to play the effect of closed system, and this will be very limited under the situation of battlefield; Water-sealed drainage bottle and inlet pipe mouth will have certain drop, and the placement of water-sealed drainage bottle height can't guarantee under the situation of first aid in the open air; When the wounded need shift, the water in the motion in the water-sealed drainage bottle can rock, and may cause the thoracic cavity air inlet, and can't use.

The purpose of this utility model is to provide a kind of suitable complicated field environment, is equally applicable to clinically, and the pleural cavity closed drainage device more safer than water-sealed drainage bottle is to overcome above-mentioned deficiency.

The purpose of this utility model can reach like this: by liquid trap, the valve check valve, drainage bag, cassette valve and the puncture needle of attaching troops to a unit and drainage tube are formed, liquid trap is a double-decker, upper strata funnel type liquid trap is inserted in lower floor's liquid trap, both combine as a whole and seal, the upper strata liquid trap has inlet pipe, the C type of attaching troops to a unit on inlet pipe thoracentesis needle and band be the drainage tube of ear fixedly, drainage tube is put into C type thoracentesis needle, and be enclosed within on the inlet pipe, lower floor's liquid trap has the pipe of going out and negative pressure to inhale the ball interface, the upper strata liquid trap connects with the lower floor liquid trap by the valve check valve, and lower floor's liquid trap goes out to manage with the interior valve check valve of drainage bag and connects, and drainage bag is provided with the cassette valve.

Adopt the pleural cavity closed drainage device of said structure simple in structure, easy to use, with low cost, whole system is worked under totally-enclosed environment, has prevented retrograde infection fully, is not only applicable to complicated field environment, also is applicable to clinical.

Below in conjunction with accompanying drawing and instantiation this utility model pleural cavity closed drainage device is described in further detail.

Fig. 4 is the fixedly drainage tube structural representation of ear of this utility model band

As shown in Figure 1, this utility model pleural cavity closed drainage device is by liquid trap 4,6,

valve check valve

5,8, drainage bag 9, cassette valve 10 and attach troops to a unit puncture needle 1 and drainage tube 2 compositions, liquid trap 4,6 is double-decker, upper strata funnel type liquid trap 4 is inserted in lower floor's liquid trap 6, both combine as a whole and seal, upper strata liquid trap 4 has inlet pipe 3, its degree of depth enters apart from three minutes one to 1/2nd positions, upper strata liquid trap 4 tops, lower floor's liquid trap 6 is provided with negative pressure interface 11, when needing vacuum suction, opening stopper connects negative pressure and inhales ball and get final product, upper strata liquid trap 4 connects with lower floor liquid trap 6 by valve check valve 5, know from Fig. 2,

valve check valve

5,8 adopt the thin film of the special material of good toughness to make, and both sides are pressed to be incorporated in and are coated special lubricant between two valves, can make between two valves closed, can guarantee again as long as at valve check valve 5, but there is just conducting of pressure differential at 8 two ends, liquid trap 4,6 purpose is in order to guarantee when blood viscosity is excessive, can collect a certain amount of blood, utilize the weight of himself to come by

valve check valve

5,8, drainage bag 9 is provided with hanger 7 and cassette valve 10, in the bag valve check valve 8 is arranged, hanger 7 is to be fixing drainage bag 9, cassette valve 10 is opened when simple pneumothorax and is got final product, drainage bag 9 is disposable use during hemothorax, also can by valve arrange repeated use in the time of can not in time changing in the open air, lower floor's liquid trap 6 goes out valve check valve 8 connections in the Tube Drain bag 9, simultaneously for ease of putting pipe, the C type of attaching troops to a unit thoracentesis needle 1 and band be the drainage tube 2 of ear fixedly, drainage tube 2 is enclosed within on the upper strata liquid trap inlet pipe 3, C type thoracentesis needle 1 internal diameter is thicker slightly than the external diameter of drainage tube 2, drainage tube 2 is put into C type thoracentesis needle 1, fixedly ear is in the breach of C type thoracentesis needle 1, fixedly ear is that drainage tube 2 is fixed on usefulness on the thoracic wall, also as the inlet pipe sounding mark.

From Fig. 3 and Fig. 4 as can be known, C type thoracentesis needle is a C type hollow pipe, the jagged head inclination in limit, and band is the drainage tube of ear fixedly, and head has conduction hole, and there is fixedly ear at about 7CM place apart from the top.

During use, earlier in the long notch depth of thoracic cavity corresponding site work-2CM, cut skin and subcutaneous tissue, after penetrating thoracic wall simultaneously with C type puncture needle 1 and drainage tube 2 then, pinch fixedly ear on the other hand, one holds C type puncture needle 1 needle tubing, the withdraw of the needle and inlet pipe carry out simultaneously, at this moment the vim and vigour of coming from the thoracic cavity arrive upper strata liquid trap 4 by inlet pipe 3, at two liquid traps 4, produce pressure reduction between 6, arrive lower floor's liquid trap 6 by valve check valve 5, simultaneously produce pressure reduction between lower floor's liquid trap 6 and the drainage bag 9, make vim and vigour pass through valve check valve 8 and arrive drainage bags 9, cassette valve 10 opened during pneumothorax merely and both can, drainage bag 9 is disposable use during hemothorax, also by cassette valve 10 arrange back repeated use in the time of can not in time changing in the open air, minority has been needed the wounded of vacuum suction, by the negative pressure suction ball interface 11 of lower floor's liquid trap 6 top band stoppers, open stopper and connect negative pressure suction ball, can manually carry out vacuum suction.
