Description
Technical field
The present invention relates to a kind of disposable uterine cavity tissue attractor.
Background technology
When doing early pregnancy induced labor operation or extraction uterine cavity tissue is chemically examined, it is necessary to use suction apparatus for uterine cavity tissues.Pass
The suction apparatus for uterine cavity tissues of system is made up of suction device or pull bar with suction tube.Suction device is complicated, troublesome in poeration, into
This is higher；Although pull bar cost is low, pull bar negative pressure caused by when twitching is weaker, operating time length, and effect is poor；Suction tube
Need first to expand palace mouth for stainless steel Integral hollow pipe, during operation, surgical procedure needs to anaesthetize, and patient's pain is strong, this attraction
Pipe repeatedly uses, if cleaning is not clean or sterilization is not strict, it is easy to cause patient's cross-infection.
The content of the invention
It is an object of the invention to provide one kind is simple in construction, cost is low, easy to operate, 360 ° of energy is without the comprehensive cleaning in dead angle
Uterine cavity tissue, palace mouth, surgical procedure need not be expanded without anesthesia, whole painless disposable uterine cavity tissue attractor.
Realizing the technical scheme of the object of the invention is：A kind of disposable uterine cavity tissue attractor, including syringe, attachment means
And suction tube；The attachment means are provided with first port, second port and the 3rd port；The second port of the attachment means and
The first check valve and the second check valve are respectively equipped with 3rd port；First check valve only allows second port air inlet, the
Two check valves only allow the 3rd port outlet；The first port of the syringe and attachment means connects；The rear end of the suction tube
The second port of portion and attachment means connects, and the front portion of suction tube is provided with import.
The syringe includes cylinder, push rod, sealing ring and draw ring；The front portion of the push rod is arranged in cylinder；It is described close
Seal is fixed on push rod front end, and the gap between sealed cylinder and push rod；The draw ring is fixed on the rearward end of push rod.
The anterior of the suction tube tilts to side.
The anterior angle of inclination of the suction tube is 0~45 °.
The axial length of the sloping portion of the suction tube is 5~10mm.
The anterior import of the suction tube includes the aperture for being arranged on the opening of anterior side and being arranged on front end face.
The caliber of the suction tube is 2.1~5mm.
The surface of the suction tube is provided with scale.
Above-mentioned technical proposal is employed, the present invention has following beneficial effect：(1) present invention is simple in construction, cost is low,
It is disposable, in the absence of because clear up it is unnet or sterilization it is not strict and caused by cross-infection problem；Syringe diameter is than attracting
Pipe goes out greatly many, and the structure is more obvious than negative pressure caused by the twitch purely by attracting tube pull rod, and the holding time is more long, is more convenient
Searching or uterine cavity tissue of the doctor in uterine cavity to embryonic tissue are taken；Vacuum magnitude in suction tube can by doctor according to
Need to control by controlling the speed of syringe pull, operation is very easy.
(2) rearward end of the push rod of syringe of the invention sets draw ring, and doctor can more save with one-handed performance, during operation
Power.
(3) the anterior of suction tube of the invention tilts to side so that suction tube can in uterine cavity 360 ° without dead angle without
Pain implements early pregnancy induced labor or uterine cavity tissue extraction operation.
(4) caliber of suction tube of the invention is 2.1~5mm, and the size and uterine cervical mouth size are similar, therefore are grasping
Palace mouth need not be expanded when making, surgical procedure is without anesthesia, and whole painless, suitable each age group women uses.
(5) surface of suction tube of the invention is provided with scale, is easy to observe depth when stretching into uterine cavity, avoids because stretching into
Inner membrane of uterine cavity is damaged deeply, avoids misoperation from forming palace and wears phenomenon.
Brief description of the drawings
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail, wherein
Fig. 1 is the structural representation of the present invention.

Embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the disposable uterine cavity tissue attractor of the present embodiment, including syringe 1, attachment means 2 and suction tube
3。
Attachment means 2 are provided with first port 21, the port 23 of second port 22 and the 3rd.The second port 22 of attachment means 2
With the first check valve 24 and the second check valve 25 are respectively equipped with the 3rd port 23.First check valve 24 only allows second port 22
Air inlet, the second check valve 25 only allow the outlet of the 3rd port 23.
Syringe 1 is connected with the first port 21 of attachment means 2.Syringe 1 includes cylinder 11, push rod 12, sealing ring 13 and drawn
Ring 14.The front portion of push rod 12 is arranged in cylinder 11.Sealing ring 13 is fixed on the front end of push rod 12, and sealed cylinder 11 and push rod 12
Between gap.Draw ring 14 is fixed on the rearward end of push rod 12.
The rearward end of suction tube 3 is connected with the second port 22 of attachment means 2, and the front portion of suction tube 3 is provided with import.Attract
The anterior import of pipe 3 includes being arranged on the opening 31 of anterior side and the aperture 32 being arranged on front end face.The caliber of suction tube 3
