Abstract

The invention discloses a negative pressure drainage device capable of continuously resisting backflow. The negative pressure drainage device capable of continuously resisting backflow comprises a negative pressure suction device (1). The upper end port of the negative pressure suction device (1) is connected with a drainage tube (2), and the lower end port of the negative pressure suction device (1) is connected with a honeycomb duct (3). A liquid storage bag (4) with a waterproof and gas-permeable membrane is connected on the honeycomb duct (3). Connectors where the upper end port and the lower end port of the negative pressure suction device (1) are connected with the drainage tube (2) and the honeycomb duct (3) are respectively connected with a one-way inlet one-way valve (5) and a one-way outlet one-way valve (6). The negative pressure drainage device capable of continuously resisting backflow has the advantages that negative pressure forming and liquid waste discharging are synchronous, operation steps are simplified greatly, a plurality of one-way valves exist, backflow resistant effect is good, and infection probability is reduced obviously. In addition, negative suction and liquid waste storage are separated, so that the device can be used continuously in a short period (3-5 days), does not need to be changed every day, and effectively reduces medical cost.

Description

A kind of counterflow-proof negative pressure drainage device continuously

Technical field

The present invention relates to a kind of counterflow-proof negative pressure drainage device continuously, belong to technical field of medical instruments.

Background technology

Along with the continuous progress of medical science, use clinically the field of drainage technology more and more wider at present, drain comprises negative pressure drainage and non-negative pressure drainage, wherein, negative pressure drainage is mainly used in gastrointestinal decompression, wound drainage etc.

Existing negative pressure drainage device is to be connected and composed by drainage tube and spring-ring type inserting depression drainage device, be provided with upper port on depression drainage device, upper port is connected with drainage tube, in upper port and drainage tube junction, is provided with valve, first closes upper port place valve before use, open again the drain tap on depression drainage device, push negtive-pressure implement simultaneously, then close drain tap, make it to form negative pressure, open upper port place switch simultaneously, can be by the hydrops sucking-off in affected part.Need again to repeat above operation and could form negative pressure after negtive-pressure implement becomes normal pressure.The drainage device of said structure is widely used in each hospital, but in use finds that there is following problem in it:

The liquid of 1, drawing with enter in depression drainage device after gas mixes, be subject to its volume restrictions, cause drainage flow limited;

2, just can not continue drain when depression drainage device after normal pressure, and it is more loaded down with trivial details again to form the operating process of negative pressure, has strengthened clinical workload, has also increased the probability infected;

3, patient and medical worker can't quick and precisely measure the liquid drained;

4, on depression drainage device, fixture is not set, in long-time drain process and go out to check etc. and be inconvenient to fix;

5, because the hydrops drained is arranged in depression drainage device, can't discharge, causing depression drainage device is disposable apparatus, need often change, and causes medical treatment cost higher, simultaneously inconvenient sample reception.

Summary of the invention

For the above-mentioned defect existed in prior art, the technical problem to be solved in the present invention be to provide a kind of can realize vacuum suction and drainage-fluid store separate, the continuous operation of depression drainage device energy, easy to use, the counterflow-proof negative pressure drainage device continuously that can reduce medical treatment cost, can overcome the deficiencies in the prior art.

The present invention is by the following technical solutions: counterflow-proof negative pressure drainage device continuously, comprise vacuum extractor, and be connected with drainage tube in the upper port of vacuum extractor, be connected with mozzle in the lower port of vacuum extractor, be connected with liquid storing bag on mozzle; The seam that connects drainage tube and mozzle at the upper and lower port of vacuum extractor is respectively arranged with and unidirectionally advances valve and unidirectionally go out valve.

Be provided with exhaust apparatus on liquid storing bag.

Described exhaust apparatus is waterproof ventilated membrane.

Bottom on liquid storing bag is provided with leakage fluid dram, is provided with tapping valve on leakage fluid dram.

Be connected with side pipe on drainage tube, be connected with three-way valve on side pipe.

Be provided with fixation clamp at vacuum extractor; Be provided with fixture on liquid storing bag.

Described vacuum extractor is that translucent silica-gel sphere, capacity are 300-400ml.

Be provided with metering scale on vacuum extractor and liquid storing bag.

Be provided with the unidirectional flap valve that advances in the import of liquid storing bag.

Describedly unidirectionally advance check valve and unidirectional to go out check valve be unidirectional valve .

Compared with the prior art, the present invention connects mozzle in the lower port of vacuum extractor, connects liquid storing bag on mozzle; And arrange unidirectionally advance unidirectional valve and unidirectionally go out unidirectional valve at the upper and lower port of vacuum extractor, particularly importantly use waterproof ventilated membrane to replace traditional air bleeding valve, make like this in producing the negative pressure process without manual exhaust, again push when vacuum extractor forms negative pressure and drain directly can be expressed in measurable liquid storing bag simultaneously, because of the reason of unidirectional valve, can make vacuum extractor again form the negative pressure continuous operation; Thereby making multi-step simplified control in the past is that a step completes.The Yin Ben device is provided with three place's unidirectional valves, has guaranteed the anti-reflux effect, greatly reduces the possibility that retrograde infection occurs.Be connected with side pipe on drainage tube, be provided with three-way valve on side pipe, can be rinsed like this or the operation such as enteral nutrition.Be connected with holder on vacuum extractor and liquid storing bag, be convenient to like this fix.Be provided with leakage fluid dram in the liquid storing bag bottom, be provided with tapping valve on leakage fluid dram, be convenient to like this discharge opeing or specimen collection.Can use continuously because of this device simultaneously, thereby can reduce medical treatment cost and can be completed by patient's Self-operating, simple and practical.
