Description
Technical field
The present invention relates to a kind of disposable uterine cavity and organize suction pump.
Background technology
When doing early pregnancy induced labor operation or extraction uterine cavity tissue chemically examines, need to use suction apparatus for uterine cavity tissues.Traditional suction apparatus for uterine cavity tissues is made up of suction device or pull bar and suction catheter.Suction device complex structure, troublesome poeration, cost is higher; Although pull bar cost is low, the negative pressure that pull bar causes when twitching is more weak, and operating time is long, weak effect; Suction catheter is rustless steel Integral hollow pipe, needs first to expand palace mouth during operation, and operation process needs anesthesia, and patient keenly feels strongly, and this suction catheter repeatedly uses, if cleaning is unclean or sterilization is not strict, is easy to cause patient's cross infection.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, cost is low, easy to operate, can 360 ° without the comprehensive cleaning in dead angle uterine cavity tissue, without the need to expanding palace mouth, operation process organizes suction pump without the need to anesthesia, the painless disposable uterine cavity of whole process.
The technical scheme realizing the object of the invention is: a kind of disposable uterine cavity organizes suction pump, comprises syringe, connecting device and suction catheter; Described connecting device is provided with the first port, the second port and the 3rd port; The first check valve and the second check valve is respectively equipped with in second port of described connecting device and the 3rd port; Described first check valve only allows the second port air inlet, and the second check valve only allows the 3rd port to give vent to anger; Described syringe is connected with the first port of connecting device; The rearward end of described suction catheter is connected with the second port of connecting device, and the front portion of suction catheter is provided with import.
Described syringe comprises cylindrical shell, push rod, sealing ring and draw ring; The front portion of described push rod is arranged in cylindrical shell; Described sealing ring is fixed on push rod front end, and the gap between sealed cylinder and push rod; Described draw ring is fixed on the rearward end of push rod.
The front portion of described suction catheter is to lopsidedness.
The angle of inclination of the front portion of described suction catheter is 0 ~ 45 °.
The axial length of the sloping portion of described suction catheter is 5 ~ 10mm.
The import of described suction catheter front portion comprises the opening being arranged on anterior side and the aperture be arranged on front end face.
The caliber of described suction catheter is 2.1 ~ 5mm.
The surface of described suction catheter is provided with scale.
Have employed technique scheme, the present invention has following beneficial effect: (1) structure of the present invention is simple, cost is low, single use, there is not the cross infection problem produced because cleaning is clean or sterilization is strict; Syringe diameter larger than suction catheter go out many, the negative pressure that this structural rate causes by the twitch of suction catheter draw-in bar is purely obvious, and the holding time is more of a specified duration, more convenient doctor taking to the searching of embryonal tissue or uterine cavity tissue in uterine cavity; Vacuum magnitude in suction catheter can be controlled by the speed controlling syringe pull as required by doctor, and operation is very easy.
(2) rearward end of the push rod of syringe of the present invention arranges draw ring, and doctor can one-handed performance, more laborsaving during operation.
(3) front portion of suction catheter of the present invention is to lopsidedness, make suction catheter can in uterine cavity 360 ° extract operation without dead angle painless enforcement early pregnancy induced labor or uterine cavity tissue.
(4) caliber of suction catheter of the present invention is 2.1 ~ 5mm, this size and uterine cervical mouth size similar, therefore when operating without the need to expanding palace mouth, operation process is without the need to anesthesia, omnidistance painless, is applicable to each age group women and uses.
(5) surface of suction catheter of the present invention is provided with scale, is convenient to the degree of depth of observing when stretching into uterine cavity, avoids damaging inner membrane of uterine cavity because stretching into dark, avoids misoperation to form palace and wears phenomenon.
