Description

Technical Field

[0001] The utility model belongs to the technical field of gynecological diagnosis and treatment instruments, and specifically relates to an expansion-type vaginal flushing device. Background Art

[0002] Gynecological diseases are usually accompanied by symptoms such as increased vaginal discharge and vaginal inflammation. Take cervical cancer as an example. Cervical cancer is a common gynecological malignancy. The main treatment methods are surgery, radiotherapy and chemotherapy. For patients with advanced cervical cancer who receive chemoradiotherapy and close-range afterloading therapy, when the radiotherapy dose reaches a certain range, the patient's vaginal wall mucosa and endocervical canal lining will fibrose due to radiation inflammation, leading to vaginal stenosis and adhesions, resulting in poor drainage of the uterine cavity and causing pus and fluid accumulation in the uterine cavity.

[0003] In view of the above problems, vaginal douching is usually used to relieve symptoms such as vaginal mucosal congestion and edema. It also prevents vaginal adhesion and stenosis, and can promptly remove tumor necrotic tissue after radiotherapy and chemotherapy, increasing the sensitivity of radiotherapy and chemotherapy. After radiotherapy, the cervical and vaginal mucosa form a white pseudomembrane covered with fibrous exudate and leukocytes, which generally disappears about 3 months after radiotherapy. If vaginal douching is not continued at this stage, the vaginal secretions will increase and the necrotic exfoliated material cannot be completely discharged from the body, causing or aggravating the symptoms of adhesive vaginitis and (or) vaginal stenosis. Therefore, all patients with advanced cervical cancer need to do vaginal douching during hospitalization except during heavy bleeding and menstruation.

[0004] For patients with vaginal adhesions, the most commonly used flushing method in clinical practice is vaginal dilation and flushing, which uses the pressure generated by the height difference to flush through an external flushing solution through a flushing tube. The operator needs to hold the dilator in one hand and the flushing tube in the other hand to complete the clinical operation, which is cumbersome, time-consuming and laborious. In addition, during the process of flushing the patient's vagina using conventional means, the dilator and the flushing tube are prone to interference, causing the flushing tube to fit tightly against the vaginal wall or even rub against it, which not only causes discomfort to the patient, but also is not conducive to the discharge of secretions after flushing, seriously affecting the flushing effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0030] Figures 1 to 7 The first embodiment of the utility model is shown: an expansion-type vaginal flushing device, comprising a hand-held handle 1 and a vaginal expansion component 2 arranged on the outside of the hand-held handle 1; the hand-held handle 1 is a hollow structure, and its internal cavity serves as a flushing liquid flow channel 3; the outlet of the flushing liquid flow channel 3 is connected to the flushing component 4; a switch valve component 5 is also arranged in the flushing liquid flow channel 3; the switch valve component 5 is mechanically linked with the vaginal expansion component 2 to start vaginal flushing while achieving vaginal expansion.

[0031] See also Figure 2 , Figure 3 , Figure 4 and Figure 7In a specific implementation, the vaginal expansion component 2 includes two jaws 201 arranged opposite to each other, and the two jaws 201 are respectively hinged to the hand-held handle 1 through a pin 202. One of the jaws 201 is used as an active jaw 201a, and its end is bent upward to form a hand-held portion 203; the other jaw 201 is used as a driven jaw 201b, which can move in the opposite direction with the action of the active jaw 201a. A toothed ring structure 204 that meshes with each other is provided between the pin 202 of the active jaw 201a and the pin 202 of the driven jaw 201. A U-shaped spring sheet 205 is also abutted between the hand-held portion 203 and the hand-held handle 1. Specifically, the toothed ring structure 204 includes a first toothed ring 204a that moves with the active jaw clamp 201a and a second toothed ring 204b that moves with the driven jaw clamp 201b. When the user applies a gripping force to the hand grip 203, the U-shaped spring sheet 205 is compressed. At this time, the hand grip 203 of the active jaw clamp 201a rotates toward the hand grip rod 1, and its head rotates away from the hand grip rod 1. Since the first toothed ring 204a and the second toothed ring 204b are meshed with each other, the head of the driven jaw clamp 201b also rotates away from the hand grip rod 1 under the action of the toothed ring structure 204. The active jaw clamp 201a and the driven jaw clamp 201b work together to achieve the purpose of expanding the vagina. On the contrary, when the user releases the grip 203, the U-shaped spring sheet 205 resets and drives the grip 203 of the active jaw 201a to rotate away from the hand-held grip 1. At this time, the head of the active jaw 201a rotates toward the hand-held grip 1, thereby driving the head of the driven jaw 201b to rotate toward the hand-held grip 1, so that both the active jaw 201a and the driven jaw 201b return to their initial positions. Preferably, in order to facilitate the user to apply grip force, a grip 206 is also provided on the grip 203.

[0032] like Figure 2 , Figure 5 , Figure 6As shown, in this embodiment, the switch valve assembly 5 includes a valve body 501 and a valve needle 502 that cooperate with each other. A section of the valve needle 502 extends out of the hand-held handle 1 and is restricted in a strip through groove 504 by a roller 503. The strip through groove 504 passes through the surface wall of the head of any of the jaw clamps 201. When the head of the jaw clamp 201 is forced to move away from the hand-held handle 1, under the action of the roller 503 and the strip through groove 504, the valve needle 502 is pulled up in the vertical direction, so that the valve hole on the valve body 501 is in an open state, and the flushing liquid can flow from the flushing liquid flow channel 3 to the flushing assembly 4; on the contrary, when the head of the jaw clamp 201 is forced to move close to the hand-held handle 1, under the action of the roller 503 and the strip through groove 504, the valve needle 502 is pressed in the vertical direction, so that its end closes the valve hole on the valve body 501, and the flushing liquid cannot flow from the flushing liquid flow channel 3 to the flushing assembly 4. In short, when the vaginal expansion component 2 is in an open state, the switch valve component 5 is also in an open state, and when the vaginal expansion component 2 is in a closed state, the switch valve component 5 is also in a closed state, so that the vaginal expansion is achieved and the vaginal irrigation is performed at the same time. Preferably, a limit block 505 for limiting the position is also provided at both ends of the roller 503.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, the flushing assembly 4 includes a flexible telescopic flushing tube 401 and a flushing head 402 connected to the outlet of the telescopic flushing tube 401. Preferably, the flushing head 402 is made of flexible silicone material, and a plurality of flushing holes are evenly distributed on its surface to ensure the flushing effect while avoiding damage to the patient's vaginal wall.

[0034] from Figure 2 It can be seen that in order to facilitate the delivery of flushing liquid, a liquid inlet pipe 6 is connected to the inlet of the flushing liquid flow channel 3, and a joint 7 is installed at the inlet of the liquid inlet pipe 6.

[0035] To sum up, the switch valve assembly 5 is mechanically linked with the vaginal expansion assembly 2. When the user applies grip force, vaginal expansion and vaginal flushing can be achieved simultaneously. It can be operated with one hand, which is convenient to use, and is conducive to improving the efficiency of vaginal cleaning. It is also convenient for patients to perform vaginal flushing operations independently. The vaginal expansion assembly 2 is arranged on the periphery of the flushing assembly 4. During the flushing process, there will be no interference between the two, so as to effectively avoid the flushing tube from excessively fitting the patient's vaginal wall, which is conducive to alleviating the patient's discomfort, and also promotes the discharge of secretions after flushing, thereby improving the vaginal flushing effect.

[0036] The utility model uses specific examples to illustrate the principle and implementation of the utility model. The above examples are only used to help understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, according to the idea of ​​the utility model, there will be changes in the specific implementation and application scope. In other words, the content of this specification should not be understood as limiting the utility model.
