A uterine perfusion device

technical field

The utility model relates to the field of medical equipment used in obstetrics and gynecology, in particular to a uterine cavity perfusion device.

Background technique

Intrauterine perfusion, that is, injecting medicinal liquid into the patient's uterine cavity through a uterine perfusion device, has been widely used in clinical treatment as a common treatment method in obstetrics and gynecology.

Existing intrauterine perfusion devices such as the "disposable intrauterine perfusion device" disclosed in Chinese patent CN206792790U include syringes, perfusion tubes and detachable needles. piston push rod.

When in use, the operator inserts the perfusion tube and the detachable needle into the patient's uterine cavity, and pushes the medicine in the syringe into the uterine cavity by pushing the piston push rod ahead of time, so as to achieve the purpose of uterine cavity treatment. The medicine may be liquid It may also be a creamy semi-fluid.

The existing problems of this uterine perfusion device are: 1. After injecting the medicament into the uterine cavity, the medicament may flow out from the cervix. 2, the needle may stab the fundus of the uterus, and the medicament outlet in the prior art is relatively single, which cannot guarantee the even application of the medicament and the uterine wall; 3, the uterine cavity perfusion device in the prior art also The depth of the uterine cavity cannot be recorded.

Detailed ways

In order to facilitate the understanding of the utility model, the utility model will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present utility model are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used in the description of the utility model are only for the purpose of describing specific embodiments, and are not used to limit the utility model.

An embodiment of a uterine cavity perfusion device in the present utility model is shown in Figures 1 to 6: it includes an injection tube 1 whose front end is used to extend into the uterine cavity, and the front end of the injection tube 1 is a ball head structure 11 to avoid Damage to the fundus. A plurality of medicament outlets 12 are opened on the side wall of the front end of the injection tube, and the medicament outlets 12 are distributed on opposite sides of the injection tube, and the medicament outlets 12 on the same side of the injection tube are arranged at intervals along the front-rear direction.

The outer periphery of the injection tube 1 is provided with the graduation marks of the injection tube for measuring the depth of the uterine cavity arranged along the front-back direction.

The tail end of the syringe 1 is connected with a syringe 5, and the syringe 5 includes a syringe sleeve 6 and a syringe piston 7 that guides and moves with the syringe sleeve 6. The front end of the syringe sleeve 6 is provided with an injection nozzle 8, and the injection nozzle 8 is connected to the injection tube. 1 end threaded connection.

A drug inlet 13 is provided at the front end of the side wall of the syringe sleeve 6, a drug feeding check valve is arranged at the drug inlet, and a drug feeding hose 14 is connected to the drug inlet.

The outer peripheral guiding movement of the injection tube is equipped with an outer sleeve 3, the outer sleeve 3 is located at the front side of the syringe 5, and the rear end of the outer sleeve is provided with an outer sleeve handle 4 for the operator to hold, and the outer sleeve handle is formed by the rear end of the outer sleeve. Composition of the peripheral surface. The front end of the outer cannula is provided with a plug 2 made of flexible material for blocking the outer cervix. The plug 2 is a tapered structure with a small front and a large rear.

In this embodiment, the plug is made of rubber material. The inner hole of the plug 2 includes a sealing section 9 for sealing and sliding fit with the outer casing and a threaded section 10 for realizing threaded connection with the outer casing. The sealing section 9 is located at The front side of the threaded segment 10. The sealing section 9 can prevent the medicament from leaking outward through the space between the outer sleeve and the injection tube, and the threaded section realizes the detachable connection between the plug and the outer sleeve, which facilitates the disassembly and replacement of the plug.

The injection tube 1 is preferably made of plastic material. When in use, the injection tube is inserted into the fundus of the patient's uterine cavity. The operator holds the outer tube handle of the outer tube and pushes the outer tube forward along the injection tube until the outer tube The plug at the front end of the tube is offset against the outer cervix of the patient's uterine cavity. At this time, the scale value on the injection tube corresponding to the rear end of the plug is the depth of the uterine cavity.

The shape and flexibility of the plug ensure that the plug can be deformed to block the outer cervix. The plug can change with the different shapes of the cervix to solve different needs such as cervical laceration and external os relaxation. Then the syringe plunger of the syringe can be pushed forward, and the syringe plunger squeezes the medicament in the syringe into the injection tube, and then smears it on the inner wall of the uterine cavity through the medicament outlet. Multiple medicament outlets ensure that the medicine can be evenly applied to the inner wall of the uterine cavity. The syringe and the injection tube are detachably connected by threads. When used for the first time, the syringe can first suck the medicament into the syringe through the injection nozzle, then connect the injection tube to the syringe, and then inject the medicament into the uterine cavity through the injection tube. When the medicine bottle is deep, it is not convenient to extend the injection nozzle into the medicine bottle to suck the medicine. When using it for the first time, you can insert the medicine feeding hose into the medicine bottle to block the injection nozzle of the syringe. The medication is drawn into the plunger chamber of the syringe through the inlet hose. In this embodiment, the intrauterine perfusion device is preferably a disposable intrauterine perfusion device.
