Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a postoperative sitz bath device for patients with perianal abscess. Background Technology

[0002] A perianal abscess is an acute or chronic suppurative infection occurring around the anus and rectum. Most perianal abscesses originate inside the anus, approximately 3 centimeters inward, in a normal anatomical structure called the anal crypt. When bacteria cause infection in this area, leading to blockage of the crypt and bacterial proliferation, inflammation and suppuration occur, affecting the surrounding tissues and spaces, thus resulting in a perianal abscess. A smaller percentage of perianal abscesses are secondary to infections outside the anus, such as infections secondary to perianal eczema or anal fissures. These are all perianal infections caused by inflammation outside the anus.

[0003] Existing sitz bath devices consist of a seat and a sitz bath basin, with a relatively simple structure. They are only for sitz baths and require manual cleaning and disinfection of the patient's anus before use. However, traditional cleaning and disinfection methods often involve manually applying medicated solution to the anus, which is inefficient and unhygienic. Furthermore, patients with perianal abscesses require sitz baths for 1-2 weeks post-surgery, 2-3 times daily for 15-20 minutes each time. The sitz bath basin is exposed to the external environment, resulting in rapid heat loss and inability to retain heat. Additionally, patients cannot clean other parts of their body while sitz bathing, making it inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a sitz bath device for postoperative cleaning of patients with perianal abscesses, which covers the sitz bath basin and part of the patient's limbs to reduce heat dissipation and facilitate cleaning of other parts of the body.

[0005] To achieve the above objectives, the basic solution of the present invention is: a sitz bath device for postoperative cleaning of patients with perianal abscess, including a seat and a sitz bath basin disposed on the seat, and also including a shielding mechanism, wherein the shielding mechanism includes a rotating shaft, an airbag and a curtain;

[0006] The rotating shaft is vertically arranged, and one end of the rotating shaft is connected to a power source that controls its rotation. The power source is installed on the back of the seat.

[0007] One end of the airbag is connected to the rotating shaft, and the airbag is wound around the rotating shaft. A clamping mechanism is provided on one side of the rotating shaft, and the other end of the airbag passes through the clamping mechanism. When the clamping mechanism clamps, it divides the airbag into two parts. A slot is provided at the clamping mechanism. The end of the airbag that is not connected to the rotating shaft is connected to a card block that engages with the slot, and the end of the airbag is connected to an integrated inflation and deflation mechanism.

[0008] One side of the curtain is connected to the bottom of the airbag. The curtain is made of waterproof and flexible material, and the bottom of the curtain is located below the sitz bath.

[0009] The working principle and beneficial effects of this basic solution are as follows: This technical solution utilizes airbags to surround the armpits of the body. When the airbags inflate, they press against the body, thus achieving a barrier and protective function. The curtain is connected to the airbags, which can cover the body below the airbags, achieving a waterproof effect. This allows the patient to wash the body above the airbags and the legs during a sitz bath. At the same time, it covers the sitz bath basin below the body, reducing heat loss.

[0010] The clamping mechanism divides the airbag into two parts. The airbag located outside the clamping mechanism inflates and surrounds the body. The clamping mechanism clamps the airbag to prevent gas from entering the airbag wrapped around the rotating shaft. By controlling the length of the airbag located outside the clamping mechanism, the size of the airbag that can be wrapped around can be controlled to accommodate patients of different body types.

[0011] Furthermore, the side of the airbag that contacts the human body is provided with several first pressure sensors. The output end of the first pressure sensor is connected to the first input end of the first pressure comparator. The second input end of the first pressure comparator is connected to the first pressure threshold memory. The output end of the first pressure comparator is connected to the inflation control end of the inflation and deflation mechanism.

[0012] The first pressure sensor collects the pressure signal between the airbag and the human body and transmits it to the first pressure comparator. The first pressure comparator compares the collected pressure signal value with the magnitude of a first pressure threshold to determine whether the airbag and the human body are tightly connected, ensuring that the airbag and the human body resist pressure and play a role in blocking water flow.

[0013] Furthermore, the seat has an annular groove around its periphery, and the curtain has a slider on the side near the end of the airbag that is not connected to the pivot, and the slider is slidably connected to the annular groove.

[0014] The curtain slides within the annular groove via a slider, allowing it to encircle the seat and ensure its concealment of the sitz bath tub.

[0015] Furthermore, it also includes a cleaning mechanism, which includes a movable plate, a baffle, and a cleaning sprayer;

[0016] The movable plate is placed on top of the sitz bath, the movable plate is set horizontally, the movable plate is slidably connected to the seat, and the movable plate is set from bottom to top from the side where the back of the seat is located.

[0017] The baffles are located on both sides of the movable plate and connected to the movable plate. The cleaning sprayer is located between the two baffles. Both the baffles and the cleaning sprayer are mounted on the connector. The connector is connected to a moving mechanism that controls its reciprocating movement. The moving mechanism is mounted on the seat.

[0018] The moving mechanism controls the movement of the baffle and the cleaning sprayer. Since the baffle is connected to a moving plate, the moving plate moves synchronously. During use, the baffle, cleaning sprayer, and moving plate are moved towards the side closest to the buttocks. The moving plate is positioned under the buttocks to catch any splashing liquid during washing, preventing it from falling into the sitz bath. The baffle is positioned on both sides of the moving plate to prevent liquid from splashing outwards. Falling liquid lands on the moving plate, which is tilted so that liquid can slide down its slope to the outside.

[0019] Furthermore, it also includes a control mechanism, which comprises a camera, a horizontal rotating wheel, a vertical rotating wheel, a display screen, and a remote control;

[0020] The camera and the cleaning sprayer are both mounted on the horizontal rotating wheel, which is mounted on the vertical rotating wheel, and the vertical rotating wheel is mounted on the connecting piece;

[0021] The display screen is mounted on the remote control, and the output end of the camera is connected to the input end of the display screen. The remote control is equipped with a horizontal rotating wheel forward rotation control button, a horizontal rotating wheel reverse rotation control button, a vertical rotating wheel forward rotation control button, and a vertical rotating wheel reverse rotation control button. The output ends of the horizontal rotating wheel forward rotation control button and the horizontal rotating wheel reverse rotation control button are respectively connected to the forward rotation control end and the reverse rotation control end of the horizontal rotating wheel. The vertical rotating wheel forward rotation control button and the vertical rotating wheel reverse rotation control button are respectively connected to the forward rotation control end and the reverse rotation control end of the vertical rotating wheel.

[0022] The camera captures images of the patient's buttocks, which are then displayed on a screen so the patient can check the condition of the affected area. Using corresponding buttons on the remote control, the rotation of the horizontal and vertical rollers is controlled, directing the cleaning spray towards the affected area for targeted cleaning.

[0023] Furthermore, the side of the baffle facing the human body is arc-shaped, and a second pressure sensor is provided on the side wall. The output end of the second pressure sensor is connected to the first input end of a second pressure comparator. The second input end of the second pressure comparator is connected to a second pressure threshold memory. The output end of the second pressure comparator is connected to the motion control end of the moving mechanism.

[0024] The second pressure sensor collects the pressure signal between the baffle and the buttocks and transmits it to the second pressure comparator. The second pressure comparator compares the collected pressure signal value with the magnitude of a second pressure threshold to determine whether the baffle is in contact with the buttocks. When the baffle is in contact with the buttocks, the moving mechanism stops.

[0025] Furthermore, a liquid receiving box is provided on the side of the movable plate near the movable mechanism. The liquid receiving box is located below the movable plate and is detachably connected to the seat.

[0026] Liquid that slides off the moving plate is collected by a liquid receiving box for easy use. Attached Figure Description

[0028] The reference numerals in the accompanying drawings include: seat 1, sitz bath 2, shielding mechanism 3, curtain 4, annular groove 5, slider 6, moving plate 7, baffle 8, moving mechanism 9, liquid receiving box 10. Detailed Implementation

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0032] This invention discloses a postoperative sitz bath device for patients with perianal abscess, such as... Figure 1 As shown, it includes a seat 1 and a sitz bath 2 disposed on the seat 1, and also includes a shielding mechanism 3, which includes a pivot, an airbag and a curtain 4.

[0033] The rotating shaft is vertically positioned, with one end connected to a power source that controls its rotation. This power source is fixedly mounted (welded, glued, riveted, etc.) to the backrest of seat 1 via elastic telescopic components (such as springs, elastic sponge layers, telescopic rods, etc.). One end of the elastic telescopic component is welded to the backrest, and the other end is welded to the power source. This allows the patient to move within a certain range via the elastic telescopic component, meeting their movement needs while ensuring a stable connection between the airbag and the body. Alternatively, the power source can be detached from the backrest. In use, the power source is removed from the backrest, and the airbag surrounds the body. The airbag inflates and presses against the body, achieving clamping and positioning between the airbag and the body.

[0034] The power source is an electric motor, which is welded to the back of the seat 1. The bottom of the back of the seat is connected to the upright of the seat 1. There is a gap between the back of the seat 1 and the back of the seat so that the curtain 4 can surround the seat 1. The bottom of the back of the seat is located below the curtain 4.

[0035] One end of the airbag is connected to a rotating shaft (e.g., by bonding), and the airbag is wound around the rotating shaft. A clamping mechanism is provided on one side of the rotating shaft, which can be an existing electric clamp. The other end of the airbag passes through the clamping part of the clamping mechanism. When the clamping mechanism clamps, it divides the airbag into two parts. A slot is provided at the clamping mechanism. The end of the airbag not connected to the rotating shaft is connected to a locking block that engages with the slot. This end of the airbag is also connected to an integrated inflation and deflation mechanism, which can be a fan. The integrated inflation and deflation mechanism is fixedly installed (e.g., by welding, riveting, etc.) at the bottom of the seat 1.

[0036] One side (i.e. the top) of the curtain 4 is connected to the bottom of the airbag (e.g., by adhesive). The curtain 4 is made of a waterproof and flexible material (e.g., a plastic rubber waterproof layer). The bottom of the curtain 4 is located below the sitz bath 2, which is placed in the middle of the seat 1.

[0037] This technical solution utilizes an airbag surrounding the body under the armpits (such as the waist or chest area). The airbag inflates and presses against the body, providing a barrier and protection. A curtain 4 connects to the airbag, shielding the body below and providing waterproofing. The patient's legs extend directly beneath the curtain 4. During a sitz bath, the patient washes the area above the airbag and their legs. Water flows to the airbag and slides down the outside of the curtain 4 to the ground, preventing water from entering the sitz bath basin 2. Simultaneously, it shields the area below the body, reducing heat loss from the sitz bath basin 2.

[0038] The clamping mechanism divides the airbag into two parts. The airbag located outside the clamping mechanism inflates and surrounds the body. The clamping mechanism clamps the airbag to prevent gas from entering the airbag wrapped around the rotating shaft. By controlling the length of the airbag located outside the clamping mechanism, the size of the airbag that can be wrapped around can be controlled to accommodate patients of different body types.

[0039] Preferably, the side of the airbag that contacts the human body is provided with several first pressure sensors (which can be connected by bonding or embedding). The output end of the first pressure sensor is electrically connected to the first input end of the first pressure comparator. The second input end of the first pressure comparator is electrically connected to the first pressure threshold memory. The output end of the first pressure comparator is electrically connected to the inflation control end of the inflation and deflation mechanism.

[0040] The first pressure sensor collects the pressure signal between the airbag and the human body and transmits it to the first pressure comparator. The first pressure comparator compares the collected pressure signal value with a first pressure threshold to determine whether the airbag and the human body are tightly connected. When the collected pressure signal value is less than the first pressure threshold, the first pressure comparator outputs a control signal to the inflation control terminal of the inflation and deflation mechanism. The inflation and deflation mechanism continuously inflates the airbag, causing it to expand and press against the human body, thus acting as a water flow barrier.

[0041] More preferably, the seat 1 has an annular groove 5 around its periphery, and the curtain 4 has a slider 6 fixedly attached (e.g., by bonding, welding, etc.) on the side near the end of the airbag that is not connected to the rotating shaft. The slider 6 is slidably connected to the annular groove 5. When the airbag is controlled to surround the human body, the curtain 4 moves with the airbag. The curtain 4 slides in the annular groove 5 through the slider 6, so that the curtain 4 surrounds the seat 1, ensuring the shielding effect on the sitz bath 2.

[0042] In a preferred embodiment of the present invention, the postoperative sitz bath device for patients with perianal abscess further includes a cleaning mechanism, which includes a movable plate 7, a baffle 8, and a cleaning sprayer. The movable plate 7 is placed on top of the sitz bath 2, and is arranged horizontally. The movable plate 7 is slidably connected to the seat 1, and is inclined from bottom to top from the side where the backrest of the seat 1 is located.

[0043] The baffles 8 of the cleaning mechanism are located on both sides of the movable plate 7 and connected to the movable plate 7. The bottom of the baffles 8 is welded to the top of the movable plate 7. The cleaning sprayer is located between the two baffles 8. Both the baffles 8 and the cleaning sprayer are fixedly installed (e.g., welded, riveted, etc.) on the connecting parts (such as frames or rods). The connecting parts are connected to a moving mechanism 9 that controls its reciprocating movement. The moving mechanism 9 is fixedly installed (e.g., welded, riveted, etc.) on the seat 1 via a bracket, with a gap between it and the seat back so that the curtain 4 can enclose the entire equipment. The cleaning mechanism is placed inside the curtain 4 and is thus concealed. The cleaning sprayer can be an existing electric nozzle and a liquid storage container. The electric nozzle is connected to the liquid storage container. The moving mechanism 9 uses an electric push rod, cylinder, hydraulic cylinder, rodless cylinder, etc.

[0044] The moving mechanism 9 controls the movement of the baffle 8 and the cleaning sprayer. Since the baffle 8 is connected to the moving plate 7, the moving plate 7 moves synchronously. During use, the baffle 8, cleaning sprayer, and moving plate 7 are moved towards the side closest to the buttocks. The moving plate 7 is positioned under the buttocks to catch any splashing liquid during the cleaning process, preventing it from falling into the sitz bath 2. The baffle 8 is positioned on both sides of the moving plate 7 to prevent liquid from splashing outwards. Falling liquid lands on the moving plate 7, which is tilted, allowing the liquid to slide down its slope to the outside.

[0045] After cleaning, the moving mechanism 9 controls the moving plate 7, baffle 8 and cleaning sprayer to return to the rear side of the sitz bath 2, so as not to affect the patient's use of the sitz bath.

[0046] In a preferred embodiment of the present invention, the postoperative sitz bath device for patients with perianal abscess further includes a control mechanism, which includes a camera, a horizontal rotating wheel, a vertical rotating wheel, a display screen, and a remote control.

[0047] Both the camera and the cleaning sprayer are mounted (e.g., by welding, snap-fitting, riveting, screw connection, etc.) on the horizontal roller, which in turn is mounted on the vertical roller, which is then mounted on a connector. Motors are connected to the central shafts of both the horizontal and vertical rollers; the motor for the vertical roller is welded to the connector, and the motor for the horizontal roller is welded to the vertical roller. The camera is a high-definition waterproof camera with its own light source, or an additional searchlight can be installed on the camera.

[0048] The display screen is fixedly mounted on the remote control. The output of the camera is electrically connected to the input of the display screen. The camera captures images of the patient's buttocks and transmits them to the display screen. The remote control has forward and reverse rotation control buttons for the horizontal and vertical rotation wheels. The outputs of the forward and reverse rotation control buttons for the horizontal and vertical rotation wheels are electrically connected to the forward and reverse rotation control terminals of the horizontal and vertical rotation wheels, respectively. Similarly, the forward and reverse rotation control buttons for the vertical and vertical rotation wheels are electrically connected to the forward and reverse rotation control terminals of the vertical rotation wheels, respectively.

[0049] The camera captures images of the patient's buttocks, which are then displayed on a screen so the patient can check the condition of the affected area. Using corresponding buttons on the remote control, the rotation of the horizontal and vertical rollers is controlled, allowing the cleaning sprayer to rotate horizontally or vertically towards the affected area for targeted cleaning.

[0050] More preferably, the side of the baffle 8 facing the human body is arc-shaped, and a second pressure sensor is provided on this side wall. The output of the second pressure sensor is electrically connected to the first input of a second pressure comparator. The second input of the second pressure comparator is electrically connected to a second pressure threshold memory, and the output of the second pressure comparator is electrically connected to the movement control terminal of the moving mechanism 9.

[0051] The second pressure sensor collects the pressure signal between the baffle 8 and the patient's buttocks and transmits it to the second pressure comparator. The second pressure comparator compares the collected pressure signal value with a second pressure threshold to determine whether the baffle 8 is in contact with the buttocks. When the collected pressure signal is less than the second pressure threshold, it indicates that the baffle 8 is not in contact with the buttocks, and the second pressure comparator outputs a control signal to the movement control terminal of the moving mechanism 9, controlling the moving mechanism 9 to move continuously, so that the baffle 8, the cleaning sprayer, and the moving plate 7 gradually approach the patient's buttocks; otherwise, the baffle 8 is in contact with the buttocks, and the moving mechanism 9 stops.

[0052] A reset button can also be set on the remote control. The reset button is electrically connected to the reset control terminal of the moving mechanism 9 to control the moving mechanism 9 to reset.

[0053] In a preferred embodiment of the present invention, a liquid receiving box 10 is provided on the side of the movable plate 7 near the movable mechanism 9. The liquid receiving box 10 is located below the movable plate 7 and is detachably connected to the seat 1, such as by snap-fit ​​or screw connection. When it is inconvenient to directly drain the liquid on the movable plate 7, the liquid receiving box 10 is installed to collect the liquid that slides off the movable plate 7, which facilitates liquid collection, avoids environmental pollution, and also prevents liquid from splashing onto the curtain 4.
