[0019] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0020] Example

[0021] The anorectal care applicator described in this embodiment is as follows: Figures 1 to 3 As shown, it includes a shell 1, which is made of plastic. In order to facilitate the installation of its internal components, the shell 1 is divided into two halves in front and back during production.

[0022] The housing 1 houses an air cylinder 8, an air bag 5, and a liquid storage bottle 2, arranged sequentially from right to left. A piston 9 is located within the air cylinder 8. The air bag 5 is made of rubber, which maintains stability under high pressure and provides reliable support and cushioning. It also possesses excellent anti-swelling strength and flexibility, adapting to various operating conditions. The air cylinder 8 and the liquid storage bottle 2 are also made of plastic.

[0023] A push rod 7 is fixed on the piston 9, and a first through hole communicating with the inside and outside is opened at the top of the shell 1 corresponding to the push rod 7. The upper end of the push rod 7 independently passes through the first through hole and is fixed with a push plate 6; when in use, the piston 9 is controlled to move up and down repeatedly in the cylinder 8 by the push plate 6 and the push rod 7.

[0024] An air inlet hole communicating with the inside and outside is provided on the side wall of the air cylinder 8 below the corresponding piston 9. A first one-way valve 10 is installed in the air inlet hole, which only allows external air to enter the air cylinder 8. An air vent hole communicating with the inside and outside is provided on the outer shell 1 corresponding to the air inlet hole. When the piston 9 moves upward in the air cylinder 8, negative pressure is generated inside the air cylinder 8. External air enters the air cylinder 8 through the first one-way valve 10, but cannot escape from the first one-way valve 10.

[0025] The gas cylinder 8 and the airbag 5 are connected by a first connecting pipe 12 so that the interiors of the two are communicated. A second one-way valve 11 is installed in the first connecting pipe 12 to limit only the gas in the gas cylinder 8 to enter the airbag 5. When in use, the piston 9 moves downward to compress the gas, and the gas in the gas cylinder 8 enters the airbag 5 through the first connecting pipe 12. The second one-way valve 11 set in the first connecting pipe 12 prevents the gas entering the airbag 5 from returning to the gas cylinder 8.

[0026] The first connecting pipe 12 is connected to a position near the bottom of the gas cylinder 8. A distance is reserved between the piston 9 and the bottom of the gas cylinder 8. The first one-way valve 10 and the second one-way valve 11 are both located at this distance. They are close to the bottom of the gas cylinder 8 to prevent the piston 9 from moving downward excessively and blocking the first one-way valve 10 and the second one-way valve 11.

[0027] The airbag 5 is connected to the liquid storage bottle 2 through a second connecting tube 4 so that the interiors of the two are communicated; the second connecting tube 4 is connected to the liquid storage bottle 2 near the bottle mouth to prevent the liquid from flooding the second connecting tube 4 and entering the airbag 5 from the second connecting tube 4 when the liquid is injected into the liquid storage bottle 2.

[0028] A second through hole communicating with the inside and outside is opened on the top of the shell 1 corresponding to the bottle mouth of the liquid storage bottle 2. The bottle mouth of the liquid storage bottle 2 passes through the second through hole and is connected to a bottle cap 3. The bottle cap 3 is connected to the bottle mouth of the liquid storage bottle 2 through a thread.

[0029] The liquid storage bottle 2 is connected to an infusion catheter 13 for draining liquid. The infusion catheter 13 communicates with the interior of the liquid storage bottle 2. During use, the other end of the infusion catheter 13 is connected to a medication delivery tube, which is inserted into the patient's anus and rectum. The liquid medicine in the liquid storage bottle 2 is delivered to the patient's anus and rectum through the infusion catheter 13 and the medication delivery tube. The infusion catheter 13 is connected to the bottom of the liquid storage bottle 2 and can drain the liquid medicine in the liquid storage bottle 2 as cleanly as possible.

[0030] The infusion catheter 13 is provided with a regulating valve 14 for controlling its opening and closing; the regulating valve 14 is a prior art, such as the regulating valve 14 on the infusion tube. When in use, the roller on the regulating valve 14 rolls to squeeze the infusion catheter 13 to control the passage of liquid. The regulating valve 14 is closed when injecting liquid medicine into the liquid storage bottle 2 or inflating the air bag 5; when the drug delivery tube is inserted into the anal canal, the regulating valve 14 is opened, and the liquid medicine in the liquid storage bottle 2 is delivered through the infusion catheter 13 under the pressure provided by the air bag 5.

[0031] An observation window communicating with the inside and outside is provided on the side wall of the housing 1 corresponding to the liquid storage bottle 2. The liquid storage bottle 2 is made of transparent plastic, which is convenient for medical staff to observe the liquid in the liquid storage bottle 2 through the observation window.

[0032] A first partition is fixed between the gas cylinder 8 and the air bag 5, and a second partition is fixed between the gas bag 5 and the liquid storage bottle 2. The first partition and the second partition provide better stability for the gas cylinder 8, the air bag 5 and the liquid storage bottle 2 inside the housing 1.

[0033] A valve is installed on the second connecting tube 4, with its control switch located outside the housing 1. During production, a microvalve is installed on the second connecting tube 4 between the airbag 5 and the liquid storage bottle 2. A corresponding slot is provided in the housing 1, connecting the inside and outside of the microvalve. The control switch of the microvalve is located outside the housing 1 through the slot. During use, the user controls the opening or closing of the second connecting tube 4 by controlling the valve, thereby opening or closing the passage from the airbag 5 to the liquid storage bottle 2. When filling the airbag 5 with gas, the valve can be closed to prevent gas leakage.

[0034] In actual use:

[0035] The user pre-fills the airbag 5 with gas through the cooperation of the gas cylinder 8 and the piston 9. The airbag 5 expands under air pressure until it fills the space between the first and second partitions. If the second connecting tube 4 is not equipped with a valve, the liquid medicine must first be filled into the liquid storage bottle 2 before the gas is added. At this time, the regulating valve 14 must be closed. The gas is present in the liquid storage bottle 2 and the airbag 5. When the regulating valve 14 is opened, the liquid medicine in the liquid storage bottle 2 is delivered to the patient's anus and rectum through the cooperation of the infusion catheter 13 and the drug delivery tube under the action of air pressure. If the second connecting tube 4 is equipped with a valve, the valve can be closed, and the airbag 5 can be filled with gas before the liquid medicine is added to the liquid storage bottle 2. Filling the liquid storage bottle 2 with sufficient liquid medicine before delivering the medicine avoids repeated filling of the liquid medicine and improves work efficiency. At the same time, the airbag 5 is pre-filled with gas. During drug delivery, the liquid medicine is automatically delivered by air pressure, reducing the number of steps in the delivery process and leaving more time for medical staff to complete other tasks and observe the patient's condition.
