Problems solved by technology

[0003]Another problem related to the aspirator during the operation is the blockage problem. Because sometimes there are blood clots or tissues in the aspirated liquid, it is often easy to cause the aspirator to be blocked. There are a variety of anti-blocking designs, which have achieved certain results. However, blockages still occur in clinical practice. It often takes a lot of precious time to unblock the blocked suction device during surgery. Sometimes the only way is to replace the suction device. solve

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0019] The novel sucker head of the present invention has a length of about 20-30cm and an inner diameter of about 5-10mm. Its end has a smooth flow regulating and flushing device 2, and the suction device has a flushing side hole 1 on the side of the device position. It can be used for dredging and flushing when the device is blocked, so that the suction head has an adjustable flow rate and can be quickly dredged and flushed when it is blocked, and can achieve the purpose of completely closing the suction. At the same time, because of its sleek design, it does not affect the sutures in the operation.

[0020] After the new suction head is connected to the negative pressure suction device, the purpose of adjusting the suction flow can be achieved by rotating the flow adjustment knob 5 at the end, and can be completely closed ( figure 2 , im...

Abstract

The invention discloses a suction apparatus head. The end of the head is provided with a flow adjusting and flushing device. A flushing side hole is arranged at one side of a suction apparatus at the position of the device. The flow adjusting and flushing device is of smooth structure, the middle of which is provided with a main cavity and an auxiliary cavity, and the main cavity and the auxiliary cavity are both of 'T'-shaped structure. A knob is arranged on the flow adjusting and flushing device and can change the positions of the main cavity and the auxiliary cavity, thus realizing the flow adjustment by the communicating rate of the main cavity and a suction tube cavity and flushing the blocked suction apparatus by the communication between the auxiliary cavity and the flushing side hole to solve the blocking problem.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a suction device head. Background technique [0002] Aspirator is one of the essential surgical instruments in surgery, it can absorb bleeding and other fluids during surgery, and keep the surgical field of view clear. It is required that the suction force should be appropriate during the operation. If the suction force is too small, the operation field of view will not be clear enough. Especially in the case of massive bleeding, the surgeon will not be able to see clearly and cannot stop the bleeding. In severe cases, it will cause The patient died. If the suction force is too large, the tissue contacted by the suction device will be damaged, causing an accident or blockage of the suction device. At present, clinically, the suction power of the aspirator is mainly controlled by the nurse adjusting the wall-type suction outlet switch, which is very inconvenient. At the same time, the suctio...
