Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a vaginal function exerciser. Background Art

[0002] The main treatment for gynecological cervical cancer, endometrial cancer, and vaginal cancer is radiotherapy, which includes external irradiation and intravaginal close-range irradiation. The vast majority of patients with gynecological tumors such as cervical cancer, endometrial cancer, and vaginal cancer require close-range radiotherapy, which is a radiotherapy technique that directly applies radiation to the corresponding part of the vagina according to the location of the lesion. However, while achieving good local control, it is also easy to cause vaginal mucosal atrophy, adhesion, and stenosis, especially for patients with a good prognosis. It will seriously affect the subsequent quality of life, especially the quality of sexual life. Therefore, it is necessary to use vaginal douches and vaginal dilators for long-term vaginal rehabilitation within 1 to 2 years after close-range radiotherapy to reduce the impact of late vaginal toxic reactions.

[0003] According to diagnosis and treatment practice, vaginal rehabilitation is required after vaginal radiotherapy or treatment of other gynecological diseases. During the vaginal rehabilitation process, correct vaginal dilation operation directly affects the rehabilitation effect, including the control of dilation position, dilation amount, and dilation process. However, since it involves gynecological treatment, patients are willing to complete vaginal rehabilitation operations by themselves, but the existing rehabilitation equipment makes it difficult for patients to accurately perform vaginal rehabilitation operations.

[0004] Although the existing vaginal douches allow patients and their families to douche by themselves, they do not have a dilation function. The commonly used vaginal dilators are vaginal specula used for gynecological examinations. Such vaginal dilators require high medical literacy of the operator. It is difficult for general patients and their families to perform them by themselves at home. The operation is inconvenient and it is difficult to achieve vaginal rehabilitation exercises. Therefore, a vaginal function exerciser is urgently needed to solve this problem. Summary of the invention

[0063] As an optional embodiment, the pump assembly includes:

[0064] A bottle support 106 is fixedly connected to one side of the main housing 101. A bottle cap 107 is placed in the bottle support 106. The bottle cap 107 is used to be threadedly connected to the bottle. The bottle is used to contain liquid medicine or saline.

[0065] The first pump body 104 is fixedly connected in the main housing 101 , one end of the first pump body 104 is connected to the bottle body, and the other end of the first pump body 104 is connected to the first hose 3 . The first pump body 104 is used to pump the liquid in the bottle body to the first hose 3 .

[0066] As an optional embodiment, the first pump body 104 is an air pump, the air inlet end of the first pump body 104 is connected to the atmosphere, the air outlet end of the first pump body 104 is connected to one end of a connecting hose 105, the other end of the connecting hose 105 is connected to the interior of the bottle body through a bottle cap 107, and a liquid outlet pipe 108 is provided on the bottle cap 107, one end of the liquid outlet pipe 108 is connected to the interior of the bottle body, and the other end of the liquid outlet pipe 108 is connected to the first hose 3.

[0067] The bottle body contains physiological saline or liquid medicine, and then the bottle cap 107 is screwed into the bottle body and placed upside down in the bottle body bracket 106. When the first pump body 104 is an air pump, the first pump body 104 is started to pump air into the bottle body, and the air gathers at the top of the inverted bottle body, squeezing the physiological saline or liquid medicine into the liquid outlet tube 108, and then the liquid is pumped to the liquid nozzle 209 for flushing or medication.

[0073] The heating temperature of the heating ring 111 does not exceed 37° C., which can avoid damage to the insertion rod 206 and the expansion unit 207 and prevent high-temperature burns in the vagina.

[0074] When the second pump body 109 is an air pump, the second pump body 109 pumps air to expand the expansion unit 207, and then the second pump body 109 exhausts air to shrink the expansion unit 207, and this is repeated to achieve the vaginal exercise function.

[0075] The expansion amount of the expansion unit 207 can be changed by controlling the second pump body 109, and the patient can select a suitable expansion diameter according to actual conditions. Generally, the expansion diameter of the expansion unit 207 does not exceed 3.5 cm.

[0076] When the second pump body 109 is a liquid pump, the liquid enters the insertion rod 206 to expand the expansion unit 207, and then the second pump body 109 is reversed to make the liquid flow back and the expansion unit 207 contract, and this is repeated to achieve the vaginal exercise function.

[0077] When the pumped fluid is liquid, the end of the second pump body 109 away from the second hose 4 is connected to the liquid storage tank 110, and an exhaust port is provided on one side of the connecting seat 202. When in use, the exhaust port needs to be opened in advance, and the second pump body 109 is started to allow the liquid to fill the insertion rod 206.

[0084] One end of the crankshaft connecting rod 10911 is hinged to the rack 1097, and the other end of the crankshaft connecting rod 10911 is hinged to the crankshaft 10910, the crankshaft 10910 is rotatably set in the pump body shell 1091, one end of the crankshaft 10910 is axially connected to the output shaft of the motor 1099, and the fixed end of the motor 1099 is fixedly connected to the pump body shell 1091.

[0085] When in use, by starting the motor 1099, the crankshaft 10910 and the crankshaft connecting rod 10911 drive the rack 1097 to reciprocate in the guide block 1098, so that the rack 1097 drives the turntable 1093 through the gear 1094 to drive a number of extrusion bearings 1096 to move the extrusion pump body hose 1095. One end of the pump body hose 1095 is connected to the atmosphere or the liquid storage tank 110, and the fluid is pumped into the insertion rod 206 to expand the expansion unit 207. The reciprocating motion of the rack 1097 changes the rotation direction of the turntable 1093, thereby changing the pumping direction, realizing the expansion and contraction of the expansion unit 207, and the expansion and contraction frequency of the expansion unit 207 can be changed by changing the rotation speed of the motor 1099.
