Abstract
Operation negative-pressure suction pipe relates to medical apparatus and instruments.It comprises sucking head 1, sucking head connects negative pressure catheter 2, negative pressure catheter connects liquid storage container and negative pressure produces source.Described negative pressure catheter is provided with negative pressure adjusting device 3, described negative pressure adjusting device is be combined with the internal threaded nut 5 that can move left and right adjustment on the tube wall that a section of negative pressure catheter has external screw thread 8, the ventilative seam 6 that the negative pressure catheter tube wall at the internal and external screw thread place of screwing is provided with longitudinally, communicate with tube chamber 7, can local or whole coverings or expose ventilative seam when screwing mobile when about nut.The beneficial effect that utility model produces: the ventilative seam of this utility model because being provided with at the threaded engagement place of suction catheter longitudinally, communicating with tube chamber, can local or whole coverings or expose ventilative seam when screwing mobile when about nut, thus have adjusted negative pressure pressure, reach the technical requirement of suction process.Structure is simple, and effect is good.
Description
Technical field:
This utility model relates to medical apparatus and instruments, relates generally to a kind of operation negative-pressure suction pipe.
Background technology:
Often produce hydrops at the internal lesions place of patient, in medical procedure, also constantly can produce blood and slime, tissue fluid etc., above-mentioned all need adopts negative-pressure suction pipe to be drawn out.Existing suction catheter comprises sucking head, negative pressure catheter, fluid reservoir and negative pressure generating device, during use, sucking head is inserted into focal zone or operative site, opens negative pressure generating device, blood and slime, hydrops etc. is drawn out by the suction nozzle of sucking head.During the defect of existing negative-pressure suction pipe, the negative pressure that suction process produces is constant, when negative pressure is large or suction nozzle is too close organize time, often tissue has been attracted, have impact on normally carrying out of suction operation.And when little, the capture velocity of negative pressure hour suction is too slow, so, be badly in need of the adjustable negative-pressure suction pipe of a kind of negative pressure.
Utility model content:
The purpose of this utility model, be to provide a kind of operation negative-pressure suction pipe of adjustable pressure, according to circumstances can regulate the attraction negative pressure of suction catheter at suction process at any time, with hurtless measure, fast the hydrops of focal zone or field of operation, blood and slime, bad tissue etc. be drawn out.
Content of the present utility model is, operation negative-pressure suction pipe, comprises sucking head 1, sucking head connects negative pressure catheter 2, negative pressure catheter connects liquid storage container and negative pressure produces source.Described negative pressure catheter is provided with negative pressure adjusting device 3, described negative pressure adjusting device is be combined with the internal threaded nut 5 that can move left and right adjustment on one section of tube wall that negative pressure catheter has external screw thread 8, the ventilative seam 6 that the negative pressure catheter tube wall at the internal and external screw thread place of screwing is provided with longitudinally, communicate with tube chamber 7, can local or whole coverings or expose ventilative seam when screwing mobile when about nut.
The beneficial effect that utility model produces:
The ventilative seam of this utility model because being provided with at the threaded engagement place of suction catheter longitudinally, communicating with tube chamber, can local or whole coverings or expose ventilative seam when screwing mobile when about nut, thus have adjusted negative pressure pressure, reach the technical requirement of suction process.Structure is simple, and effect is good.

Detailed description of the invention:
As shown in figure 1 and 2, a kind of operation negative-pressure suction pipe, comprises sucking head 1, sucking head connects negative pressure catheter 2, negative pressure catheter connects liquid storage container and negative pressure produces source.Negative pressure catheter 2 is provided with negative pressure adjusting device 3, described negative pressure adjusting device is be combined with the internal threaded nut 5 that can move left and right adjustment on one section of tube wall that negative pressure catheter has external screw thread 8, the ventilative seam 6 that the negative pressure catheter tube wall at the internal and external screw thread place of screwing is provided with longitudinally, communicate with tube chamber 7, can local or whole coverings or expose ventilative seam when screwing mobile when about nut.The right side negative pressure catheter of adjustable nut being provided with a fixed handle 9, holding it for attracting during operation.The left side negative pressure catheter wall of adjustable nut fixes a bulge loop 4, using the left limit as nut movement.
