Abstract
This utility model relates to medical instruments field, particularly a kind of special negative pressure suction catheter for being connected with gynecological suction tube.For connecting the negative-pressure suction pipe of gynecological suction tube, comprise suction catheter, the front end of described suction catheter is fixedly connected with piecing devices, and piecing devices comprise the connecting hole inserted for gynecological suction tube, and the tube wall of described piecing devices is embedded with support spring.This utility model structure is simple, easy to operate, piecing devices in the past and negative-pressure suction pipe are designed in aggregates, the inner side tube wall of whole negative-pressure suction pipe is smooth, obviously can reduce the stopping state inhaled in the process of palace, avoid and in suction palace process, carry out dismounting because of the blocking of negative-pressure suction pipe and remove contamination, and the uterine cavity infection risk brought therefrom increases, intraoperative blood loss increases and the prolongation of operating time.
Description
Technical field
This utility model relates to medical instruments field, particularly a kind of special negative pressure suction catheter for being connected with gynecological suction tube.
Background technology
Gynecological suction tube is a kind of metal medical appliance that department of obstetrics and gynecology are conventional, for stopping early pregnancy, can also be used in the multiple pathological changes situations such as endometrial hyperplasia, suspected tumor, infertility, cervical polyp for the in utero thing of sucking-off from uterus.As shown in Figure 1, general gynecological suction tube 1 has strip suction port for one end sidewall, and the other end of gynecological suction tube 1 connects negative-pressure suction pipe 3 by joint 2.Also do not have clinically at present to be a kind ofly specifically designed to the negative-pressure suction pipe be connected with gynecological suction tube, existing common negative-pressure suction pipe 3, owing to there is caliber and material difference with gynecological suction tube 1, need carry out transition by joint 2 pairs of gynecological suction tubes 1 with negative-pressure suction pipe 3 and be connected.
As shown in Figure 2, existing joint 2 existence is connected situation loosely with negative-pressure suction pipe 3, when joint 2 is connected with negative-pressure suction pipe 3, owing to being placed on negative-pressure suction pipe 3 in joint 2, caliber difference is there is in joint 2 with the expanding channels place 4 of negative-pressure suction pipe 3, and then cause the inner side tube wall at expanding channels place 4 rough, expanding channels place 4 be easy to by endometrium or other in utero thing block, medical worker has to repeatedly from uterine cavity, take out gynecological suction tube 1 in attraction process, again to gynecological suction tube 1, joint 2, the operation of removing tamper is carried out in the junction of negative-pressure suction pipe 3 three, this considerably increases uterine cavity infection risk, too increase intraoperative blood loss and extend operating time, also bring inconvenience to operator simultaneously.
Utility model content
The purpose of this utility model is the above-mentioned deficiency overcoming prior art, provides a kind of simple and practical, minimizing blocking, the easy to operate negative-pressure suction pipe for connecting gynecological suction tube.
For achieving the above object, this utility model provides following technical scheme:
For connecting the negative-pressure suction pipe of gynecological suction tube, comprise suction catheter, the front end of described suction catheter is fixedly connected with piecing devices, and piecing devices comprise the connecting hole inserted for gynecological suction tube, and the tube wall of described piecing devices is embedded with support spring.
Above-mentioned for connecting in the negative-pressure suction pipe of gynecological suction tube, on described piecing devices, the size of connecting hole and the match of pipe diameter of gynecological suction tube joint, connect gynecological suction tube by piecing devices, can ensure the air-tightness of junction.
Above-mentioned for connecting in the negative-pressure suction pipe of gynecological suction tube, described suction catheter is elastic hose.
Above-mentioned for connecting in the negative-pressure suction pipe of gynecological suction tube, described suction catheter and piecing devices are transparent material and make, and are convenient to observe in negative-pressure suction pipe whether have foreign matters from being blocked.
Above-mentioned for connecting in the negative-pressure suction pipe of gynecological suction tube, the making material of described piecing devices is rigid plastics, the piecing devices with certain degree of hardness are convenient to insert gynecological suction tube, the piecing devices with certain degree of hardness are not yielding under negative pressure condition yet, can avoid causing attraction pipeline obstructed because of joint distortion.
compared with prior art, the beneficial effects of the utility model:this utility model structure is simple, easy to operate, piecing devices in the past and negative-pressure suction pipe are designed in aggregates, the inner side tube wall of whole negative-pressure suction pipe is smooth, obviously can reduce the stopping state inhaled in the process of palace, avoid and in suction palace process, carry out dismounting because of the blocking of negative-pressure suction pipe and remove contamination, and the uterine cavity infection risk brought therefrom increases, intraoperative blood loss increases and the prolongation of operating time.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only for explaining this utility model, and be not used in restriction this utility model.
embodiment 1
As shown in Figure 3, the present embodiment is for connecting the negative-pressure suction pipe of gynecological suction tube, comprise suction catheter 5, the front end of described suction catheter 5 is fixedly connected with piecing devices 6, piecing devices 6 comprise the connecting hole 61 inserted for gynecological suction tube 1, the size of described connecting hole 61 and the match of pipe diameter of gynecological suction tube 1 joint, gynecological suction tube 1 is connected by piecing devices 6, the air-tightness of junction can be ensured, the tube wall of piecing devices 6 is in addition embedded with support spring 62, to ensure hardness and the deformation restoring force of piecing devices 6.
As shown in Figure 4, the present embodiment structure is simple, easy to operate, joint 2 is in the past designed in aggregates with negative-pressure suction pipe 3, the inner side tube wall of whole negative-pressure suction pipe is smooth, obviously can reduce the stopping state inhaled in the process of palace, avoid and in suction palace process, carry out dismounting because of the blocking of negative-pressure suction pipe and remove contamination, and the uterine cavity infection risk brought therefrom increases, intraoperative blood loss increases and the prolongation of operating time.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
