Negative-pressure drainage apparatus

Abstract

The invention discloses a negative-pressure drainage apparatus which comprises a shell, a spiral vane and a motor, wherein the motor is arranged in the shell, and the front end of the motor is provided with driving teeth; the driving teeth are meshed with driven teeth; the end part of the shell is provided with a connector and a motor joint; the connector is matched with a liquid passage; the motor joint is used for connecting an external power supply and the motor; the negative-pressure drainage apparatus further comprises expansion foam arranged in an anti-refluence opening, and a one-way valve. The negative-pressure drainage apparatus is reasonable in design, is simple and compact in structure, and is capable of easily and rapidly stirring and draining possibly-solidified liquid; the shell is provided with a hydrops bag, and the hydrops bag is vacuumized into a negative pressure state by use of vacuumizing equipment; the connector is connected with a blood waste tube, and blood waste is drained into the blood waste tube by virtue of suction force generated by negative pressure, and is stirred by virtue of the spiral vane with reasonable design, so that circulation of the blood waste is facilitated; when in use, the negative-pressure drainage apparatus is convenient and rapid, is capable of improving the working efficiency of working personnel, reducing the operation time and reducing operation risks, and is suitable for large-range popularization and use.

Description

Technical field [0001] The invention relates to a medical device, in particular to a negative pressure drain used for treatment of waste liquid in surgery. Background technique [0002] A hospital is a medical institution whose main purpose is to provide people with medical care services. It can help the recipients relieve their pain, but only with the advanced and convenient hospital equipment can they better reduce the pain of the patients; when performing operations in the hospital, the operating room The equipment often can give medical staff higher work efficiency, shorten the operation time, and at the same time reduce the pain of patients. [0003] For example, when a doctor performs an operation, there will be granular muscle tissue and bleeding at the incision. Many liquids are used to clean the patient’s wound, so bloody sewage will be produced; and the bloody sewage is processed through Negative pressure device and catheter are used for suction, during this process, the...

Problems solved by technology

[0003] For example: when a doctor performs an operation, there will be granular muscle tissue and bleeding at the incision, and many of them will use some liquid to wash the patient's wound, so bloody sewage will be produced; and the treatment of these bloody sewage is through In this process, the port of the negative pressure device is easily blocked, and when the negative pressure device is not used for a period of time, the bloody sewage is easy to coagulate, and it is easy to block the catheter and the negative pressure device It is very inconvenient for medical staff to use it, which will cause catheter blockage, prolong operation time and increase operation risk
