Description

Technical Field

[0001] The utility model relates to the technical field of drainage tubes, in particular to a double-cavity uterine drainage tube with a compression air bag. Background Art

[0002] Intrauterine drainage tubes are relatively common medical devices in clinical practice, mainly used to discharge fluid, blood, pus and other liquids in the uterine cavity through the drainage tubes; there are many types of intrauterine drainage tubes on the market, and most of them are provided with two inner and outer chambers. The inner chamber is connected to the outside world and is used to drain the accumulated fluid or blood in the uterine cavity out of the body to reduce the risk of infection and promote wound healing. The outer chamber is connected to the compression airbag on its top, and the compression airbag is expanded by ventilating into the compression airbag to achieve compression and hemostasis operation in the uterine cavity.

[0003] However, this type of double-lumen uterine drainage tube with a compression balloon can only perform compression and drainage operations during use. When medication needs to be injected, it is also injected through the inner cavity, which can cause the accumulated fluid in the inner cavity to flow back into the uterine cavity and cause secondary infection. This type of double-lumen uterine drainage tube lacks a channel for independent medication injection, which is not conducive to promoting aseptic medication injection operations and affects the treatment effect. In view of this, we proposed a double-lumen uterine drainage tube with a compression balloon. Utility Model Content

[0004] The purpose of the present utility model is to provide a double-cavity uterine drainage tube with a compression airbag to solve the defects mentioned in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] Preferably, a sealing sleeve is fixedly mounted on the plug-in tube, and the sealing sleeve is threadedly connected to the threaded joint.

[0012] Preferably, the size of the plug-in tube matches the size of the threaded joint, and the end of the threaded joint abuts against the inner wall of the sealing sleeve.

[0013] Preferably, a sealing plug is fixedly connected to the end tube body of the injection tube away from the insertion tube through a pulling belt, and the sealing plug is snap-fitted to the injection tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model has an inner cavity for drainage, and an outer cavity is used in conjunction with a compression airbag. The compression airbag can be expanded to perform compression operations. In addition, the provided injection tube can be used to inject liquid medicine alone, which is convenient to use and can achieve the effect of being portable and used for separate injection of liquid medicine.

[0016] 2. The utility model provides a plug-in tube, and since a medicine liquid filter cotton net is provided in the plug-in tube, the medicine liquid filter cotton net can filter out particulate impurities in the medicine liquid. At the same time, as the medicine liquid filter cotton net is soaked, the medicine on the medicine liquid filter cotton net can block the entry of external bacteria. Each time the medicine liquid is injected subsequently, the plug-in tube is replaced as a whole, which can avoid the injection of external bacteria into the uterine cavity and the effect of secondary infection.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-6 The utility model provides a technical solution: a double-cavity uterine drainage tube with a compression airbag, comprising a drainage tube body 1, wherein an inner cavity 10 and an outer cavity 11 are provided inside the drainage tube body 1, and both ends of the inner cavity 10 are connected to the outside for drainage operation; a compression airbag 12 is integrally formed at the front end of the drainage tube body 1, and the compression airbag 12 is connected to the outer cavity 11; an inflation tube 13 connected to the inner part of the outer cavity 11 is fixedly installed at the rear end of the drainage tube body 1, and is used to inflate the compression airbag 12 to expand the compression airbag 12, and the expanded compression airbag 12 can be used to achieve the effect of compression and hemostasis;

[0028] Specifically, a drug injection tube 2 is fixedly installed on the inner wall of the inner cavity 10, and the bottom end of the drug injection tube 2 passes through the drainage tube main body 1 and is fixedly installed with a threaded joint 21. A plug-in tube 23 is inserted into the threaded joint 21, and a drug liquid filter cotton mesh 231 is fixedly installed on the inner wall of the tube body at the rear end of the plug-in tube 23, and an injection tube 22 is fixedly installed at the front end of the plug-in tube 23. The drug liquid filter cotton mesh 231 can filter out large impurities in the drug liquid, and as the drug liquid filter cotton mesh 231 is soaked, the drug liquid on the drug liquid filter cotton mesh 231 can block the entry of external bacteria, thereby achieving the effect of safe and hygienic use.

[0029] In this embodiment, a threaded tube 14 is fixedly installed at the end of the inflation tube 13, and a threaded cap 15 is threadedly connected to the threaded tube 14. Tightening the threaded cap 15 on the threaded tube 14 can prevent air leakage.

[0030] Specifically, a first one-way valve 141 is fixedly installed on the smooth section of the tube body at the rear end of the threaded tube 14. The first one-way valve 141 can be an air nozzle structure on a tire, which can realize inflation and deflation operations. The first one-way valve 141 is an existing conventional technology and will not be repeated here.

[0031] Furthermore, a drainage bag connector 16 is fixedly installed at the bottom end of the drainage tube body 1, and the drainage bag connector 16 is connected to the inner cavity 10, so that a drainage bag can be installed at the drainage bag connector 16 to contain the accumulated fluid.

[0032] In addition, a second one-way valve 20 is fixedly installed on the top tube body of the injection tube 2. The second one-way valve 20 is located near the compression airbag 12, which only allows the internal liquid to flow out and prevents the accumulated liquid from entering the injection tube 2.

[0033] It is worth noting that a sealing sleeve 24 is fixedly installed on the plug-in tube 23, and the sealing sleeve 24 is threadedly connected to the threaded joint 21; the size of the plug-in tube 23 is adapted to the size of the threaded joint 21, and the end of the threaded joint 21 rests on the inner wall of the sealing sleeve 24 to improve the sealing performance.

[0034] It is worth noting that a sealing plug 25 is fixedly connected to the end tube body of the injection tube 22 away from the insertion tube 23 through a pulling belt 251. The sealing plug 25 is snap-fitted to the injection tube 22 to achieve a sealing operation on the end of the injection tube 22.

[0035] When using the double-cavity uterine drainage tube with compression airbag of the present invention, the drainage tube body 1 is placed in the uterine cavity, and the drainage bag connector 16 is connected to the external drainage bag. The drainage operation can be performed normally, and the compression airbag 12 is inflated by the inflation tube 13. As the compression airbag 12 expands, the compression airbag 12 can perform compression to stop bleeding, etc.

[0036] In addition, insert the plug tube 23 into the threaded joint 21, and tighten the sealing sleeve 24 on the threaded joint 21, use an external syringe to inject the medicine into the injection tube 22, and the medicine can flow out from the end of the injection tube 2 into the uterine cavity for treatment. The medicine filter cotton mesh 231 can filter out large impurities in the medicine, and as the medicine filter cotton mesh 231 is soaked, the medicine on the medicine filter cotton mesh 231 can prevent the growth of external bacteria. When injecting the medicine for the second time, the injection tube 22 will be disassembled and replaced as a whole, and then the medicine injection operation will be performed.
