Abstract
A disposable aspiration catheter for the induction of labor (8-12 weeks) is provided. It comprises a catheter tube having one smooth round end and another aspiration end connected to pipes of an electric aspiration apparatus, scale marks provided on the outer wall of the catheter tube, and an opening provided in the catheter wall closely to the round end. A retractable cannula is further provided inside the catheter tube and has a front end in sharp tooth shape and extending to the opening of the catheter body, and a rear end in handle shape and extending from a slant hole out of the catheter body. The cannula inside the catheter tube is of good rigidity, can support the soft catheter tube and guide it into the uterine cavity properly, and then it is retracted for further aspiration.
Description
[technical field]
This utility model is relevant with the artificial abortion apparatus, specifically, is that the matched disposable uterine cavity of a kind of and electronic or manual suction pump is organized suction catheter, is used for 8 to 12 all early pregnancy induced labor operations.
[background technology]
Traditional artificial abortion apparatus is improved, reduce artificial abortion and bring pain, guaranteed that the safety of operation is the target that people pursue always to patient.Chinese patent CN2488478Y and CN2675062Y disclose a kind of disposable uterine cavity of 4 to 8 all very early pregnancies that is applicable to and have organized suction catheter, a kind of improvement that conventional art is made exactly, but be not suitable for 8 to 12 all early pregnancy induced labor operations.This is that tissue substance is more because the pregnant capsule of 8 to 12 all early pregnancies is bigger, needs to use the bigger suction catheter of diameter.And the suction catheter made from the flexibility material, along with diameter increases, its rigidity descends, and it directly can't be inserted in the uterine cavity.
[summary of the invention]
In order to overcome the deficiency of technique scheme, the utility model proposes following new improvement project: a kind of disposable uterine cavity is organized suction catheter, the outer tube wall of body is provided with scale, one end is slick round end, and the tube wall of nearly round end is provided with an opening, and the other end is the suction inlet head that is connected with the electric abortion suction unit conduit, it is characterized in that, body is built-in with the piston rod that can twitch, and the front end of piston rod is stretched and reached opening part, and the rear end is one handle and stretches in outside the body.
In above-mentioned technical scheme, the piston rod that body is built-in with has favorable rigidity, can support softish body, and body is introduced in the uterine cavity, wait to arrive needed position after, pinch handle and extract the piston rod out, just can implement induced labor.
As further, do not interfere with each other in order to make the piston rod and the suction inlet head of body, in becoming an angle that gradient is arranged near suction inlet head punishment fork-shaped, the handle of piston rod stretches out from angle.
Further again, the piston nose is spine and the bonded shape of sawtooth, is convenient to auxiliary colluding and draws pregnant capsule and the tissue substance that stops up the body opening.

Fig. 2 is the structural representation of Fig. 1 middle tube body.
Fig. 3 is the structural representation of piston rod among Fig. 1.
Fig. 4 is the view that the angle among Fig. 1 is furnished with seal closure.
[specific embodiment]
Describe concrete embodiment in detail below in conjunction with this utility model embodiment.
Consult shown in each accompanying drawing, disposable uterine cavity is organized suction catheter, and it is slick round end that the outer tube wall of body 10 is provided with scale 12, one ends, and the tube wall of nearly round end is provided with an opening 13, and the other end is the suction inlet head 14 that is connected with the electric abortion suction unit conduit.Body 1 is built-in with the piston rod 20 that can twitch, and the front end of piston rod 20 is stretched and reached opening 13 places, and the rear end is one handle 21 and stretches in outside the body.
For the piston rod 20 and the suction inlet head 14 of body 10 are not interfered with each other, become an angle 15 that gradient is arranged near suction inlet head 14 punishment fork-shapeds, the handle 21 of piston rod 20 stretches out from angle 15, and piston rod 20 front ends are spine 22 and sawtooth 23 bonded shapes.
Come into effect induced labor when operation, body 10 and piston rod 20 stretched into uterine cavity together, wait to arrive needed position after, pinch handle 21 and extract piston rods 20 out, with a seal closure 16 of configuration angle 15 shutoff after the induced labor of enforcement negative pressure.Blocked as taking place in the operation process in opening 13 or the body 20, can open seal closure 16, piston rod 20 is inserted from angle 15, to collude with spine 22 and sawtooth 23 and draw pregnant capsule and tissue substance, and can repeatedly come and go mediation body 20, the assurance operation is carried out smoothly.
