Description

A gynecological disinfection drug delivery device

technical field

The utility model relates to a medical appliance, in particular to a gynecological disinfection drug delivery device.

Background technique

The diseases of the female reproductive system are gynecological diseases, including vulvar diseases, vaginal diseases, uterine diseases, fallopian tube diseases, ovarian diseases, etc. Gynecological diseases are common and frequently-occurring diseases in women. However, because many people lack proper understanding of gynecological diseases, lack of health care for the body, and various bad living habits, etc., their physical health is deteriorating, resulting in some women suffering from diseases that cannot be cured for a long time. Big inconvenience. In clinical practice, it is generally necessary to deliver the medicinal liquid to the inner wall of the vagina, and it is of great significance to study a gynecological medicinal device.

In clinical treatment, doctors or nurses are generally required to disinfect and administer drugs to the patient's vagina. At present, obstetricians and gynecologists mostly use tweezers to hold a cotton ball dipped in liquid medicine and probe it into the patient's vagina for disinfection, or use a drug delivery device to sterilize the vagina. Disinfectant is injected into the patient's vagina for disinfection. At present, the common single-channel drug injection, gynecological disease drug delivery device is mainly composed of a piston, a push rod, a sleeve and a drug delivery head. It cannot effectively and accurately wash the infected site, and the treatment effect is not good. , patients with long treatment cycles have been troubled for a long time. Therefore, in the treatment of gynecological diseases, there are still some problems that cannot be solved in the process of drug application and disinfection, as follows:

1. At present, there is no special device for the disinfection and application of medicine on the inner wall of the vagina, which makes the operation of drug delivery and disinfection inside the vagina difficult, and the treatment effect is not good. There is an urgent need for a medicine application device for gynecology.

2. When using tweezers to pick up cotton balls for drug administration and disinfection, it is difficult for the tweezers to enter the inner wall of the vagina, which can easily cause pain to the patient, or poke the patient's inner wall of the vagina or cervix, and it is easy to cause secondary damage to the damaged inner wall of the vagina. , increasing the difficulty of medical staff's work, is not conducive to the treatment of diseases.

3. When using cotton balls for drug administration, the cotton wool on the cotton balls is easy to remain in the vagina, which will bring adverse effects on the patient's body.

4. Directly use the syringe to inject the medicinal liquid into the vagina, and the medicinal liquid flows naturally to the affected area. Often the medicinal liquid cannot be fully applied to the affected area, and some medicinal liquid will flow out along the vagina. The dripping medicinal liquid not only causes waste, but also pollutes the affected area. The environment, safety and hygiene are poor, a large amount of medicinal liquid is consumed, and the treatment cost is increased. In addition, the use of a syringe to administer medicine is inconvenient and has certain dangers.

5. If the patient's vagina is seriously inflamed, the inner wall of the vagina or the cervix is often damaged, the inner wall of the patient's vagina is accompanied by lochia or other mucus, which is not conducive to the flow of liquid medicine, and the existing drug delivery methods and devices cannot be used to remove lochia, Affects the treatment of liquid vaginal lesions.

At present, during the treatment of gynecological diseases, the above problems cannot be solved in the process of disinfection of the inner wall of the vagina and drug application. It is of great medical significance and practical value to study a gynecological drug application device to solve the above problems.
