Description

It is a kind of to be used for pleural effusion and the drainage system of exhaust

Technical field

The invention belongs to the field of medical instrument technology, and in particular to a kind of for pleural effusion and the drainage system of exhaust.

Background technology

Have 3~15ml liquid in normal person's pleural cavity, in respiratory movement from lubricating action, but the hydrops amount in pleural cavity It is not changeless.Even normal person, it is every 24 it is small when also have 500~1000ml liquid formed and absorb.Pleural cavity Interior liquid is being absorbed from the vein end of capillary, remaining liquid is recycled to blood by lymphatic system, and filtration is in absorption Dynamic equilibrium, if since whole body or local patholoic change destroy such dynamic equilibrium, cause pleura intracavity liquid formed it is too fast or Absorbed it is slow, clinic generate pleural effusion, oppress lung or the hydrops time it is long, the easy machine of celloglobulin therein and send out Raw two layers of pleaural adhesion, so as to influence lung's respiratory function, at this moment we need to puncture and take out hydrops, and when patient is in the wall of the chest Either have in the case of defect Pulmonary Function poor at lung surface or during a large amount of pneumothoraxs, tension gas especially occurs During chest, it must just carry out effective pneumothorax closed drainage treatment rapidly.In most cases, pneumothorax patient needs to carry out continuation chest Chamber closed drainage, in a few cases, if failing to make pleura cut to heal after water-sealed drainage bottle drains, lung still cannot again, can be It is drained after drainage tube plus with negative pressure device.Thoracentesis is one relatively common in clinical position, and is convenient simple A kind of diagnostic and therapeutic method, when in pleural effusion puncture drainage or pneumothorax drainage, pleural effusion or gas it is continuous Drainage, lung tissue expansion, it is possible to cause needle point damage alveolar and trigger iatrogenic pneumothorax, clinically due to being in fear of needle point to the heart Dirty or lung tissue damage can only usually terminate relevant drainage in advance.In the prior art simply individually to product in thoracic cavity Liquid or gas are drained, and whole process is infectious high, and after drainage, when needing to clean extraction location or drug During treatment, it is punctured again, it is impossible to carry out effective drug-treated to extraction location in time, making patients' state of an illness is suffered from Person's healing time lengthening, is unfavorable for physical recovery.Therefore, be now badly in need of a kind of design rationally, accurate positioning, it is safe and reliable, Drainage system small to patient's irritation, easy to operate.

Step 3：It is fixed by puncture positioning device (3) to puncturing needle body (1) into row position, adjusts fixed plate one (108) and exist The position of resilient mounting (1b), opens the solenoid valve trigger switch (604) of propeller (6), and motor push rod (602) forward movement pushes away Dynamic needle core (106), the resilient mounting that needle core (106) is made up of fixed plate one (108), fixed plate two (107), spring (110) It is quickly sprung back, prevents needle core (106) from causing to damage to thoracic cavity；

Step 4：When carrying out hydrops drainage in thoracic cavity, adjust No.1 triple valve (404) and be communicated to negative pressure bag (405), opening is drawn Hydrops is drained into negative pressure bag by stream device (4) by casing one (101), oblique drainage trough (105), No.1 drainage tube (401) (405) in, the flow of hydrops can be adjusted by adjusting medical flow velocity speed governing valve (402) during drainage, works as negative pressure bag (405) when the pressure in reaches certain value, open negative pressure generator (403) and drainage processing, negative pressure generator are carried out to hydrops (403) negative pressure absorbing power is 50~200ml；

Step 5：When needed in thoracic cavity exhaust when, thoracic cavity becomes positive pressure by negative pressure, by adjusting No.1 triple valve (404) with Receiving flask (406) connects, and opens drainage system (4) and drains gas by casing one (101), oblique drainage trough (105), No.1 Pipe (401) drains into receiving flask (406), and receiving flask (406) is by being collected a small amount of liquid being mingled in gas, then by gas Body flows to water-sealed drainage bottle (407) by conduit, by the way that the number of underwater bubble in water-sealed drainage bottle (407) observed, adjusts medical flow velocity tune Fast valve (402) is adjusted gas flow rate, and negative pressure generator (403) is opened when thoracic cavity pressure is to certain value to gas It is drained；

Step 6：After hydrops or gas have drained in thoracic cavity, infusion device (5) is opened, when thoracic cavity is cleaned, passes through rotation No. two triple valves (503) connect cleaning solution storage bottle (505), complete 300~400ml cleaning solutions and the thoracic cavity after having drained is carried out Cleaning when needing drug therapy, adjusts No. two triple valves (503) and connects administration injection device (504), by drawing 3~5ml medicines Object, then adjust No. two triple valves (503) be switched to cleaning solution storage bottle (505) draw 10~20ml cleaning solution mixed, Mixed liquor is sent in thoracic cavity by adjusting the medical flow control valve (502) on No. two diversion pipes (501), infusion is completed Afterwards, take out and puncture needle body (1) progress wound hemostasis processing.
