Abstract
The utility model discloses a disposable anti-blocking uterine cavity tissue suction tube. The disposable anti-blocking uterine cavity tissue suction tube comprises a plastic catheter and a connector connected with a negative pressure suction device, wherein the front portion of the plastic catheter is bent, the angle of bending alpha of the plastic catheter is 10-25 degrees, a main suction hole and a secondary suction hole which are communicated with an inner cavity of the catheter are formed in the wall of the front portion of the plastic catheter, and the secondary suction hole is composed of a plurality of small holes. According to the disposable anti-blocking uterine cavity tissue suction tube, the catheter is formed by plastic in a squeezing and injection mode, the hardness and the angle of bending of the front portion of the catheter can be determined according to clinical requirements, and the catheter is disposable. The disposable anti-blocking uterine cavity tissue suction tube has the advantages of being simple in structure, convenient to use, free of cross infection, and capable of enabling a patient to feel comfortable. The secondary suction hole can prevent the main suction hole from being blocked by tissue in a uterine cavity in a suction process.
Description
Technical field
This utility model relates to a kind of area of medical devices, particularly a kind of disposable blockage resisting uterine cavity tissue suction catheter.
Background technology
At present, the uterine cavity tissue suction catheter that clinical artificial abortion is mainly used is metal material, and the repeated use of sterilization back, life-time service, and interior pipe can get rusty or gather foreign body, and may cause the human body cross infection in the use.And when being cold, metal is terribly cold, causes patient's muscular tone in the operation engineering, brings discomfort to the patient, increases doctor's operation easier.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, disposable blockage resisting uterine cavity tissue suction catheter easy to use.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of disposable blockage resisting uterine cavity tissue suction catheter, comprise plastic catheter and the joint that links to each other with negative pressure suction device, be characterized in: described plastic catheter front curvature, bent angle alpha is 10 °-25 °, anterior tube wall in plastic catheter is provided with main hole and time attraction hole of attracting that is communicated with conduit cavity, and inferior attraction hole is made up of several apertures.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the main front side that attracts the hole to be located at the anterior tube wall of plastic catheter, and inferior attraction hole is located at the rear side of the anterior tube wall of plastic catheter.
Technical problem to be solved in the utility model can also further realize that plastic catheter front curvature angle [alpha] is 13 °-15 ° by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the tube wall upper edge catheter body direction of described plastic catheter is provided with graduation mark, makes things convenient for the doctor to operate by following technical scheme.
Compared with prior art, conduit of the present utility model is extruded and injection moulding by plastics, its soft durometer and conduit front curvature angle can be determined according to clinical needs, and be disposable use articles for use, simple in structure, easy to use, can cross infection, the patient feels comfortable, inferior attraction hole can prevent in the attraction process that the main hole that attracts is stopped up by uterine cavity inner tissue.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to structural representation.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not constitute the restriction to its right.
See figures.1.and.2, a kind of disposable blockage resisting uterine cavity tissue suction catheter, the joint 1 that comprises plastic catheter 2 and link to each other with negative pressure suction device, described plastic catheter 2 front curvature, bent angle alpha is 10 °-25 °, and preferred bent angle alpha is 13 °-15 °, is provided with main hole 4 and time attraction hole 5 of attracting that is communicated with conduit cavity at the anterior tube wall of plastic catheter 2, inferior attraction hole 5 is made up of several apertures, is preferably three apertures and forms.The main front side that attracts hole 4 to be located at the anterior tube wall of plastic catheter 2, inferior attraction hole 5 is located at the rear side of the anterior tube wall of plastic catheter 2.The tube wall upper edge catheter body direction of described plastic catheter 2 is provided with graduation mark 3.
During use, the joint 1 of suction catheter is linked to each other with negative pressure suction device, plastic catheter 2 is slowly sent into uterine cavity, simultaneously judge the degree of depth of sending into according to the graduation mark 3 on the plastic catheter 2, the main hole 4 that attracts is faced toward the tissue that needs absorption, can operate, inferior attraction hole 5 can prevent from stopping up the main hole 4 that attracts at the process of attraction Middle Palace intraluminal tissue.
