Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a disposable negative pressure vaginal douche. Background Art

[0002] Vaginal irrigation is a common procedure in women's daily health care and the auxiliary treatment of some gynecological diseases. However, existing vaginal irrigation devices have many shortcomings. For example, some irrigators cannot effectively control the flow rate of the irrigation liquid, which may lead to uneven irrigation force, affect the cleaning effect, and even cause discomfort to the user; some irrigators are not reasonably designed, and liquid reflux is prone to occur, which is not only unhygienic but also may cause cross-infection risks; in addition, the reusable nature of traditional irrigators will pose a health hazard when shared by multiple people, which does not meet the high requirements of modern medical hygiene and safety.

[0003] Based on these problems, the present invention designs a disposable negative pressure vaginal lavage device to better meet the actual needs of vaginal lavage. Summary of the invention

[0004] The purpose of the present invention is to provide a disposable negative pressure vaginal irrigator, which has a unique structural design and uses the negative pressure principle to achieve effective spraying of flushing liquid. It also has a flow limiting function to accurately control the flushing flow rate and effectively prevent liquid reflux. The device is disposable as a whole, ensuring the hygiene and safety of use, providing convenient and reliable instrument support for female vaginal irrigaton, so as to solve the problems of uneven flushing force and easy liquid reflux in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] The technical solution provided by the present invention is: a disposable negative pressure vaginal irrigator, comprising a negative pressure flushing bottle (1), a connecting device (2) is threadedly provided on the upper side of the negative pressure flushing bottle (1), a negative pressure air bag (3) is fixedly provided on the upper side of the connecting device (2), a flushing head (4) is fixedly provided on the upper side of the connecting device (2), a one-way valve (5) is movably provided on the inner wall of the flushing head (4), a plurality of flushing holes (7) are provided on the upper side of the flushing head (4) and around the one-way valve (5), and a plurality of cleaning holes (6) are evenly provided on the side of the flushing head (4);

[0007] The negative pressure flushing bottle serves as a container for storing flushing liquid. Its material is made of plastic that meets medical hygiene standards. It has good sealing and a certain degree of pressure resistance. It can perform negative pressure work repeatedly to ensure that there will be no leakage during use. A threaded port is fixed on the top of the negative pressure flushing bottle. The design of the threaded port facilitates reliable connection with subsequent connecting devices, ensuring that it can be tightly screwed in and easy to install and disassemble.

[0008] Furthermore, a threaded opening is fixedly provided above the negative pressure flushing bottle.

[0009] Furthermore, the connecting device includes a connecting thread ring threadedly mounted on the inner wall of the threaded opening, a connecting pipe is fixedly arranged above the connecting thread ring, the upper part of the connecting pipe is fixedly connected to one end of the negative pressure airbag, and a fixing pipe is fixedly arranged above the negative pressure airbag;

[0010] The connecting device connects the negative pressure flushing bottle, the negative pressure air bag, the flushing head and other components, so that the entire irrigator forms a complete fluid passage and ensures that the connection between the components is stable and the sealing is good;

[0011] The connecting threaded ring is installed on the inner wall of the threaded opening of the negative pressure flushing bottle through threads. Its material is compatible with the material of the negative pressure flushing bottle, has good wear resistance and sealing properties, and ensures that the flushing liquid can be effectively prevented from leaking from the connection after tightening.

[0012] The connecting tube is fixed above the connecting threaded ring. It is a hollow tubular structure. The inner diameter is designed according to the required flushing liquid flow rate and the connection compatibility with other components. The material is medical-grade flexible plastic, which is convenient for bending and adjustment during operation while ensuring a certain strength and will not be easily damaged. The main function of the connecting tube is to guide the flushing liquid in the negative pressure flushing bottle to transmit upward, and at the same time connect the negative pressure airbag so that the effect of the negative pressure airbag can effectively act on the flushing liquid.

[0013] The fixed tube is located above the connecting tube and is fixedly connected to one end of the negative pressure airbag. The other end is used to fix the flushing head. The structure of the fixed tube is firmly and reliably connected to the flushing head and the negative pressure airbag, which ensures the smooth flow of the flushing liquid and the normal use of the device.

[0014] The negative pressure airbag is a key component for achieving negative pressure flushing. It is made of medical rubber or silicone with good elasticity and durability. When in use, the air pressure inside the negative pressure airbag can be changed by manually squeezing and releasing the negative pressure airbag, thereby forming a negative pressure environment inside the entire irrigator, causing the flushing liquid in the negative pressure flushing bottle to be sucked out and flow to the flushing head through the connecting device, thereby realizing the spraying of the flushing liquid. The size and elastic design of the negative pressure airbag have been optimized, allowing the user to operate it more easily, while generating a suitable negative pressure intensity to ensure the flushing effect.

[0015] Furthermore, the flushing head is fixedly installed above the fixed pipe, the flushing head is of hemispherical design, and a circular arc is provided on the side of the flushing head;

[0016] The flushing head directly acts on the inside of the vagina for flushing. Its overall hemispherical design conforms to the physiological structure of the human body, can better fit the internal environment of the vagina, reduce discomfort, and facilitate the even spraying of the flushing liquid to various parts. The flushing head has an arc on the side to make it smoother during insertion and use, avoiding damage to the vaginal tissue. The flushing head is fixedly installed above the fixed tube to ensure a firm connection and will not fall off during use.

[0017] Furthermore, a one-way valve is arranged on the inner wall of the flushing head, which is mainly used to control the flow rate of the flushing liquid so that the liquid medicine can only enter but not exit, thereby ensuring the infusion pressure of the surrounding cleaning holes and flushing holes, making the liquid medicine evenly distributed, and ensuring the stability and comfort of the flushing process.

[0018] Furthermore, there are four groups of cleaning holes, each group of cleaning holes has two cleaning holes installed in parallel on the side of the flushing head. A number of cleaning holes are evenly opened on the side of the flushing head. These cleaning holes are the outlets for the flushing liquid to be sprayed out, which can make the flushing liquid spray inside the vagina in a more uniform manner, thereby improving the cleaning effect.

[0019] The beneficial effects of this technical solution are:

[0020] (1) This irrigator is a disposable product, which avoids the risk of cross infection caused by sharing by multiple people and meets the high standards of hygiene and safety in modern medicine. It can be discarded directly after use by the user without complicated cleaning and disinfection, which is convenient and quick.

[0021] (2) By setting a one-way valve, the flow rate of the flushing liquid can be accurately controlled according to the actual needs and feelings of the user, so that the liquid medicine can only enter but not exit, ensuring the infusion pressure of the surrounding cleaning holes and flushing holes, and making the liquid medicine evenly distributed, thereby ensuring that the flushing process is more comfortable and stable, avoiding adverse effects on vaginal tissue due to too fast or too slow flow rate, and improving the cleaning effect and user experience.

[0022] (3) Reasonable connection structure design between various components, such as threaded connection and sealing, can effectively prevent the leakage of flushing liquid during use; at the same time, the one-way valve not only realizes flow rate control, but also has the function of preventing liquid backflow, which further ensures the hygiene and safety of use.

[0023] (4) The hemispherical design of the flushing head and the rationally arranged cleaning holes on the side enable it to better fit the internal environment of the vagina, achieve all-round and uniform flushing, reduce the user's discomfort during the flushing process, and improve the effectiveness of flushing. In addition, the aperture setting is sufficient, the angle is large, the pressure is appropriate, and it also has a significant adsorption effect on large particles of secretions.

[0024] (5) The negative pressure flushing bottle has a large capacity, which can clean more thoroughly and prevent excessive secretions from remaining due to capacity problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The specific implementation process is as follows:

[0034] Confirm that the product packaging is intact, open the package, take out the disposable negative pressure vaginal douche, and check whether the components are damaged, deformed, or otherwise abnormal, to ensure that the device is in normal usable condition;

[0035] According to the flushing situation, prepare an appropriate amount of special vaginal flushing liquid, slowly pour the flushing liquid into the negative pressure flushing bottle 1, and be careful not to overflow the flushing liquid. The filling amount is generally not more than two-thirds of the volume of the negative pressure flushing bottle 1, so as to reserve a certain amount of air space for the subsequent formation of negative pressure;

[0036] Align the connection device 2 of the irrigator with the threaded opening 101 above the negative pressure flushing bottle 1, and rotate the connection thread ring 201 in a clockwise direction until the connection device 2 and the negative pressure flushing bottle 1 are tightly screwed together, ensuring that there is no looseness or leakage at the connection;

[0037] Afterwards, the user can take a comfortable standing or lying posture, such as squatting slightly when standing, with legs apart, and then hold the douche and gently and slowly insert the douche head 4 into the vagina. The insertion depth is adjusted according to personal physical condition and doctor's advice. Generally, it is sufficient to insert the douche head 4 to a suitable depth so that the cleaning hole 6 can fully act on the area that needs to be doucheed.

[0038] Hold the negative pressure airbag 3 with your hand, and start to squeeze and release the negative pressure airbag 3 slowly and rhythmically. Pay attention to using moderate force when squeezing, and observe the flushing liquid spraying out from the cleaning hole 6 and the flushing hole 7 of the flushing head 4. According to the actual feeling and flushing effect, control the flow rate and spraying amount of the flushing liquid by adjusting the force and frequency of squeezing the negative pressure airbag 3 to achieve comfortable and effective flushing.

[0039] Working principle: When using the disposable negative pressure vaginal douche, first put an appropriate amount of douche liquid into the negative pressure douche bottle 1, and then screw it tightly with the threaded opening 101 of the negative pressure douche bottle 1 through the connecting threaded ring 201 of the connecting device 2 to ensure that the entire device is well sealed. The user holds the douche and slowly and gently inserts the douche head 4 to a suitable depth in the vagina. Then, manually squeeze the negative pressure airbag 3, at this time, the gas in the negative pressure airbag 3 is discharged, the internal air pressure is reduced, and under the action of negative pressure, the douche liquid in the negative pressure douche bottle 1 is sucked into the connecting tube 202 and flows along the fixed tube 203 toward the douche head 4, and finally evenly sprayed inside the vagina through the cleaning hole 6 on the side of the douche head 4 and the flushing hole 7 above, achieving the purpose of flushing and cleaning. The one-way valve 5 can effectively prevent the douche liquid from flowing back, ensuring the hygiene and safety of use.
