Description
Technical field
This utility model is related to a kind of serous cavity negative pressure drainage device, belongs to technical field of medical instruments.
Background technology
Serous cavity paracentesis are the conventional diagnosis of a clinic and therapeutic procedure technology, including pleurocentesiss, abdominal cavity
Paracentesis, pericardiocentesises etc..Pleurocentesiss (thoracentesis) typically refer to hydrothorax tapping.Work as thoracic cavity
Hydrops amount can cause respiratory dysfunction, patient the uncomfortable even circulatory disturbance performance such as dry cough, uncomfortable in chest, out of breath occur when more,
Hydrops need to be extracted to solve pressure symptom.In addition, used as the reflection of primary disease, extraction hydrothorax is carried out checking and can be appreciated that hydrops
Property, assists the cause of disease of clear and definite hydrothorax.Equally, peritoneocentesises (abdominocentesis) are primarily referred to as entering abdominal cavity
Row punctures, extracts the operating process of hydrops.For example：Some are high because of malnutrition, right heart function exhaustion, nephrotic syndrome, portal vein
Pressure, peritonitis, the transfer of malignant tumor peritoneum etc. can cause abnormal accumulation or hemoperitoneum of peritoneal cavity liquid etc..So serous cavity is punctured
Diagnosis of the art to clinical disease, relief of symptoms, or even treatment are very helpful.
Traditional tapping method is all from the method that national institution of higher learning diagnosticss teaching material is introduced, and the method is used
For many years, it is successful to majority of cases.But for encapsulated effusion or Small Amount hydrops, fat patient, using tradition puncture
Method, puncture success rate is not high, complication easily occurs.Generally conventional tapping method needs two or more than two doctors
Teacher completes, and operates relatively complicated.Recently there is document report, using central negative-pressure suction device, carry out splanchnocoel puncture
Drainage, clinical effectiveness is preferable.U.S. Pneumology Department doctor also with Sterile vacuum bottle (Baxer) vacuum suction, for pleura
Chamber puncture drainage.
But serous cavity puncture drainage is used as a traumatic operation, with certain risk.Sometimes some are had simultaneously
Send out disease to occur.By taking pleurocentesiss as an example, such as：Pleura reaction, patient shows as giddy, perspiration, pale complexion, cardiopalmus, extremity
Send out cool, the symptom such as blood pressure drops, caused by polyphyly vagus reflex is hyperfunction.If after a large amount of quick drawing liquids, or even there is multiple extensional
Pulmonary edema, at once after surgery often or in 1 hour, occurred at the latest less than 24 hours.Early symptom is coughed for play, rapid breathing, breast
Bitterly, dysphoria, cardiopalmus.A large amount of whites or pink foam sample expectorant are followed by coughed, can occur together heat, Nausea and vomiting, severe patient occurs
Shock and stupor.Pulmonary checks and finds the extensive moist rale of the lung of patient two.Rabat is shown in large stretch of obscurity boundary patch shadow.The side of its prevention
Method is that requirement drawing liquid is unsuitable too fast.At present because negative pressure suction device control is poor, patient is easily set above-mentioned untoward reaction occur.
Therefore, those skilled in the art is devoted to developing a kind of i.e. achievable easy, the negative pressure scalable of one man operation
Serous cavity negative pressure drainage device.
