Abstract
The utility model discloses a uterine cavity hemostasis anti-adhesion thermo-sensitive hydrogel injection device, and relates to a medical instrument. The injection device comprises an injector and an injection rod, the injection rod is sleeved on the injector in a sealing manner, the top of the injection rod is solid, vertically staggered holes are arranged at a position on the wall of the injection rod, and the distance from the position to the top of the injection rod ranges from 0.5cm to 2cm. The injection device has the advantages that the injection device is simple in structure and convenient to use, a scale and soft rubber are arranged on the injection rod, the depth of a uterine cavity of a patient can be accurately positioned, the injection rod is effectively prevented from excessively extending into the uterine cavity to pierce a uterus, the holes are arranged on the wall of the injection rod, hydrogel can cover a wound surface by 360 degrees, the holes are vertically staggered, breakage of the injection rod can be effectively prevented, and the rod head cannot be reserved in the body of the patient.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically belongs to a kind of uterine cavity bleeding stopping and adherence preventing thermosensitive hydrogel injection device.
Background technology
Intrauterine adhesion is a kind of common gynaecopathia, be common in the pedestrian worker's abortion or the spontaneous abortion dilatation and curettage after.The Therapeutic Method of intrauterine adhesion adopts dilator bar expansion back to place intrauterine device more at present, and this method blindness is big, can not recover original uterine cavity shape, and the incidence rate of adhesion once more is high.In recent years, along with the progress of medical skill, the monitoring of use hysteroscope or B ultrasonic occurred and carried out exclusion, but operation is comparatively complicated, still needs placement of intrauterine devices to prevent adhesion again.Also the someone advocates in uterine cavity to place the pyriform support, prevents adhesion again, but this support costs an arm and a leg, and needs to take out after one month, has increased less patient suffering and financial burden.
The Chinese patent of Granted publication CN101318036B discloses a kind of medical antiblocking intelligent gel rubber material and method for making thereof; This gel can effectively be kept apart wound surface and surrounding tissue, but does not have a kind of device ability accurate with this gel injection to intrauterine wound surface position.
Summary of the invention
Said defective above the purpose of this utility model is to be directed against provides a kind of ability accurate with the gel injection locational uterine cavity bleeding stopping and adherence preventing of wound surface thermosensitive hydrogel injection device in the uterine cavity.
The purpose of this utility model is achieved through following technical scheme.
A kind of uterine cavity bleeding stopping and adherence preventing thermosensitive hydrogel injection device is characterized in that be made up of syringe and injection rod, the injection rod sealing shroud is on syringe, and the injection rod top is solid, on the injection rod wall at top 0.5-2cm place, has the hole of dislocation up and down.
Said injection rod is provided with scale.
Be equipped with on the said injection rod and can slide up and down soft strand.
The outer diameter of said injection rod is 3mm, and the inner diameter of injection rod is 2mm.
During use; In uterine cavity bleeding stopping and adherence preventing thermosensitive hydrogel inhalation syringe; Injection rod is enclosed within on the syringe, soft thigh is slided to the corresponding scale of patient's uterine cavity degree of depth position, injection rod is stretched in the uterine cavity; Extremely soft thigh stops to stretch into during the place, the gel in the syringe is injected in the uterine cavity through the hole on the injection rod wall get final product on the wound surface.
The beneficial effect of this utility model is: this utility model is simple in structure, and is easy to use, and injection rod is provided with scale and soft strand, and the accurate position patient uterine cavity degree of depth prevents effectively that injection rod from stretching into excessively to pierce through the uterus; Perforate on the injection rod rod wall can overlay on the wound surface by 360 degree gel, and the hole misplaces up and down, can effectively prevent the injection rod fracture and caput is retained in the human body.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
Among the figure, 1 syringe, 2 injection rod, 3 holes, 4 scales, 5 soft thighs.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model done further describing.
As shown in Figure 1, a kind of uterine cavity bleeding stopping and adherence preventing thermosensitive hydrogel injection device is made up of syringe 1 and injection rod 2, and injection rod 2 sealing shrouds are on syringe 1, and injection rod 2 tops are solid, on injection rod 2 walls at top 0.5-2cm place, has the hole 3 of dislocation up and down.
Said injection rod 2 is provided with scale 4.
Be equipped with on the said injection rod 2 and can slide up and down soft strand 5.
The outer diameter of said injection rod 2 is 3mm, and the inner diameter of injection rod 2 is 2mm.
During use; In uterine cavity bleeding stopping and adherence preventing thermosensitive hydrogel inhalation syringe 1; Injection rod 2 is enclosed within on the syringe 1, soft thigh 5 is slided to the corresponding scale of patient's uterine cavity degree of depth 4 positions, injection rod 2 is stretched in the uterine cavity; Extremely soft thigh stops to stretch into during 5 places, the gel in the syringe 1 is injected in the uterine cavity through the hole 3 on injection rod 2 walls get final product on the wound surface.
