Description

Simple and easy suction device of manual negative pressure

Technical Field

The utility model relates to the field of medical equipment, more specifically the theory that says so, it relates to a simple and easy suction device of manual negative pressure.

Background

Ovarian cyst: is a sac-like structure formed in the ovary or on the surface of the ovary, contains liquid or solid substances, is a common gynecological disease and has higher prevalence rate in women in the childbearing age. Most ovarian cysts can disappear by themselves and cannot cause damage to human bodies. However, ovarian cysts of some patients can grow continuously, which causes discomfort of lower abdomen, abnormal menstruation and the like, and secondary diseases such as cyst rupture, pedicle torsion, infection and the like can occur when the treatment is not in time.

Ovarian endometriosis cyst: meaning that the ectopic endometrium grows within the ovary. There may be one or more cysts, which have grayish blue surface and different sizes, and the diameter is about 5cm mostly and can reach 10-20 cm. Typically, the capsule contains coffee-like viscous liquid, which is chocolate-like, and is commonly called an ovarian chocolate cyst.

The ovarian cyst of a patient is clinically found, the patient has no subjective symptoms, when the cyst is small, the patient generally does not need treatment, and the patient is required to be reviewed regularly according to medical advice. However, when the cyst has a large volume and a diameter of more than or equal to 5cm, the persistent existence of the cyst is observed for 3 to 6 months, the growth of the cyst is fast, and the influence on the ovarian function is large, the medicine or the operation treatment can be recommended.

For women in the reproductive age, after ovarian cysts are found, the properties of the ovarian cysts are observed and determined, and the ovarian cysts are divided into physiological cysts and pathological cysts. Physiological ovarian cysts are usually the most common follicular cysts and corpus luteum cysts, are mostly single-chamber and thin-walled, have the diameter of less than or equal to 8 cm, and generally disappear by themselves after observation or oral administration of the contraceptive for 2-3 months. Pathological ovarian cysts require early detection of tumor markers because ovarian cysts are classified as benign and malignant. Small benign cysts can be reviewed regularly by following medical advice, large benign cysts, which are larger than or equal to 5cm in diameter, require surgical treatment, and should be operated once malignant ovarian tumors are found.

However, chocolate cyst is regarded as an extra type of cyst, which is not a true ovarian cyst but a cyst formed by the invasion of endometriosis and the growth of ectopic endometrium on the ovary and in the ovarian cortex. The surface of the chocolate is grayish blue, and the inside of the chocolate is old blood like coffee viscous liquid and chocolate like to obtain the name of the chocolate. Since endometriosis is a major factor in infertility, many patients with chocolate cysts are accompanied by infertility symptoms, and need to be treated in accordance with the requirements for endometriosis. If necessary, surgical treatment or assisted reproduction technology is carried out to assist pregnancy.

When the patient is subjected to an operation or assisted pregnancy by an assisted reproduction technology, the patient is often recommended to carry out an ovarian cyst dissection under a laparoscope or a cyst puncture under the guidance of a vaginal B ultrasonic. When carrying out cyst puncture under the guidance of vagina B ultrasonic, negative pressure electric pump suction can be adopted to some hospitals, but can often meet the big cyst of chocolate cyst and grow for a long time and lead to the condition that the inner liquid is very viscous, often this time negative pressure pump suction just more difficultly and operate not nimble enough, need carry out manual suction with 50ml syringe. Continuous acting force is needed to maintain the negative pressure state in the manual suction process, and if the suction time is long, the physical consumption of an operator is extremely high.

SUMMERY OF THE UTILITY MODEL
