Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a safe irrigation device for clinical use in anorectal surgery. Background Technology

[0002] In clinical diagnosis and postoperative care of anorectal surgery, medical staff need to adjust irrigation parameters according to the location of the anorectal lesion, the size of the wound, and the tolerance of the rectal mucosa. The accuracy of these adjustments often relies on manual judgment and intermittent observation of the irrigation status. Currently, the industry commonly uses manual or electric irrigation devices in conjunction with basic waste fluid collection devices as the standard irrigation method.

[0003] According to experimental data in the paper "Safety Study of Clinical Irrigation Equipment Application" (Beijing Friendship Hospital, Capital Medical University, 2023), "Direct-insertion irrigation heads have risks such as delayed irrigation pressure regulation and local mucosal impact damage, and there are fluctuations in irrigation pressure, which can easily cause mucosal damage."

[0004] In practical clinical scenarios, it is evident that existing direct-insertion irrigation devices struggle to match the insertion depth with the irrigation flow rate, and insufficient experience among medical staff can easily lead to certain diagnostic and treatment risks. Therefore, the fundamental deficiency of existing anorectal irrigation techniques lies in their insufficient ability to adapt and control the irrigation to local lesions in the anorectal area, and the lack of adaptive protective design, resulting in irrigation safety issues. Therefore, it is necessary to propose a novel safe irrigation device for clinical use in anorectal surgery to address these problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a safe irrigation device for clinical use in anorectal surgery. This device is used to safely irrigate the anorectal area of ​​patients during clinical diagnosis and treatment and postoperative care in anorectal surgery. It enables adaptive matching and control of the irrigation tube insertion depth and irrigation flow rate, thereby improving the safety and effectiveness of the irrigation operation and reducing mucosal damage caused by human experience-based judgment bias and insufficient equipment adaptability.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A safe irrigation device for clinical use in anorectal surgery includes a base, a controller, and an irrigation tube. A support is provided on the base, and a storage tank and a support are fixedly connected to the side wall of the support. A collection assembly for collecting cleaning waste liquid is provided on the base. An irrigation tube for irrigating the rectum is provided on the support. A pump assembly is provided on the side wall of the storage tank. The inlet of the pump assembly is connected to the bottom of the storage tank, and the outlet of the pump assembly is connected to a connecting pipe, which is connected to the irrigation tube. The controller is used to control the operation of the pump assembly. A flow control assembly is provided on the irrigation tube for automatically adjusting the irrigation flow rate according to the depth of the irrigation tube inserted into the rectum. The flow control assembly includes a sleeve, with the irrigation tube slidably fitted onto the inner wall of the sleeve. An adjustment groove is opened on the outer wall of the irrigation tube, and the depth of the adjustment groove decreases from top to bottom. An annular protrusion is fixedly connected to the inner wall of the sleeve, and the annular protrusion is sleeved around the irrigation tube and slidably fitted with the adjustment groove. A protection assembly is provided inside the sleeve for automatically reducing the irrigation tube pressure when the irrigation tube pressure is too high.

[0007] The technical principles of the above solution are as follows: The controller regulates the pump assembly to draw flushing fluid from the storage tank, which is then delivered to the flushing tube via the connecting pipe to complete the rectal flushing. Waste fluid is collected by the collection assembly. The flow control assembly, through the sliding fit between the flushing tube and the sleeve, utilizes the gradual depth characteristic of the adjusting groove to cause the annular protrusion to squeeze the flushing tube with the insertion depth, achieving adaptive flow adjustment. When the pressure inside the flushing tube is too high, the protection assembly automatically triggers to reduce the flow orifice diameter to release pressure and prevent high pressure damage to the mucosa.

[0008] The above approach has the following beneficial effects: 1. This solution achieves adaptive matching between the insertion depth of the irrigation tube and the irrigation flow rate through a flow control component, eliminating the need for manual judgment and adjustment by medical staff. This solves the problem of difficulty in matching the insertion depth and flow rate in existing equipment, reduces the risk of mucosal damage due to lack of experience, and improves the safety of irrigation operations.

[0009] 2. This solution is equipped with protective components that can provide protection when the pressure inside the flushing tube is too high, forming a dual safety protection mechanism to further avoid impact damage to the anorectal mucosa and meet the clinical needs of patients with different mucosal tolerance levels.

[0010] 3. This solution integrates waste liquid collection components with an automated flushing control structure, which simplifies clinical operation procedures, reduces the operational burden on medical staff, and prevents flushing waste liquid from leaking and contaminating the treatment environment.

[0011] Furthermore, the end of the flushing pipe is arc-shaped, and flushing ports are opened circumferentially on the side wall of the flushing pipe.

[0012] Beneficial effects: The curved end can avoid scratching the anal mucosa during insertion, improving insertion safety; the circumferential irrigation port allows the irrigation fluid to be sprayed out evenly in a ring, avoiding single-point impact damage to the mucosa, while expanding the irrigation range.

[0013] Furthermore, the collection component includes a sewage basin fixedly connected to the bracket, a collection box fixedly connected to the bottom of the sewage basin, the collection box fixedly connected to the top of the base, a drain outlet at the bottom of the sewage basin, and the sewage basin and the collection box connected through the drain outlet.

[0014] Beneficial effects: The wastewater basin can quickly collect the flushing waste liquid, which flows into the collection box through the drain outlet, realizing centralized collection of waste liquid.

[0015] Furthermore, the protection assembly includes conduits symmetrically connected to the side wall of the flushing pipe, and L-shaped channels symmetrically opened inside the side wall of the casing; the ends of the conduits away from the flushing pipe are connected to the adjacent channels; pistons are slidably fitted inside the transverse ends of the channels, and tension springs are fixedly connected to the pistons, with the ends of the tension springs away from the pistons fixedly connected to the inner side wall of the adjacent channels; connecting rods are fixedly connected to the pistons, with the ends of the connecting rods away from the pistons extending into the casing and fixedly connected to clamping blocks.

[0016] Beneficial effects: Overpressure protection is achieved through a mechanical structure, which can respond without electrical control; under high pressure, the clamping block is hydraulically driven to clamp the flushing pipe, and after the pressure is restored, the tension spring drives the structure to reset, which is highly reliable and improves flushing safety.

[0017] Furthermore, the drain outlet is equipped with an overflow prevention component to prevent sewage from overflowing from the sewage basin; the overflow prevention component includes a plug hinged to the bottom wall of the sewage basin, a traction rope fixedly connected to the top of the plug, and a float fixedly connected to the end of the traction rope away from the plug; a drain valve is connected to the side wall of the collection box.

[0018] Beneficial effects: The float automatically triggers the anti-overflow mechanism with the liquid level, and the traction rope drives the plug to open the drain outlet, allowing sewage to flow into the collection tank and preventing sewage from overflowing.

[0019] Furthermore, a first solenoid valve is connected inside the flushing pipe, and a controller is used to control the opening and closing of the first solenoid valve.

[0020] Beneficial effects: The controller can control the opening and closing of the first solenoid valve to achieve rapid on / off control of the flushing pipe.

[0021] Furthermore, a perianal irrigation branch tube is fixedly connected to the side wall of the support. The perianal irrigation branch tube is connected to the connecting tube, and a second solenoid valve is connected inside the perianal irrigation branch tube. The controller is used to control the opening and closing of the second solenoid valve.

[0022] Beneficial effects: By switching between the first and second solenoid valves using the controller, independent control of rectal irrigation and perianal irrigation can be achieved, adapting to different diagnostic and treatment scenarios.

[0023] Furthermore, a back plate is fixedly connected to the side wall of the bracket, and a flexible pad is fixedly connected to the side wall of the back plate.

[0024] Beneficial effects: The backrest provides support for the patient, and the flexible pad conforms to the patient's body curves, improving the patient's positional comfort during rinsing.

[0025] Furthermore, handrails are symmetrically fixed to the side walls of the support frame.

[0026] Beneficial effects: Symmetrical handrails make it easier for patients to grasp and maintain a stable position, reducing body swaying during rinsing.

[0027] Furthermore, the bottom of the base is equipped with a movable component for moving the base.

[0028] Beneficial effects: The mobile component allows the device to be flexibly moved to different scenarios such as the treatment bedside and wards, adapting to diverse clinical treatment needs. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The following detailed description illustrates the specific implementation method: Example 1:

[0038] As attached Figure 1 The image shows a safe irrigation device for clinical use in anorectal surgery, comprising a base 1, a controller, and an irrigation pipe 5. A support 2 is mounted on the base 1, and a storage tank 3 and a support member 4 are bolted to the side wall of the support 2. In this embodiment, a filling pipe is connected to the top of the storage tank 3 for adding irrigation fluid to the storage tank 3. The bottom of the base 1 is equipped with a movable component for moving the base 1. In this embodiment, the movable component consists of several casters 28 bolted to the bottom of the base 1.

[0039] A pump assembly 6 is provided on the side wall of the liquid storage tank 3. The inlet of the pump assembly 6 is connected to the bottom of the liquid storage tank 3, and the outlet of the pump assembly 6 is connected to a connecting pipe 7. The connecting pipe 7 is connected to the flushing pipe 5. The controller is used to control the operation of the pump assembly 6.

[0040] like Figure 2 As shown, the end of the flushing pipe 5 is arc-shaped, and the side wall of the flushing pipe 5 has a flushing port circumferentially open.

[0041] The flushing tube 5 is equipped with a flow control component for automatically adjusting the flushing flow rate according to the depth of insertion of the flushing tube 5 into the rectum.

[0042] like Figure 2As shown, specifically, the flow control component includes a sleeve 8, a flushing pipe 5 that slides on the inner wall of the sleeve 8, and an adjustment groove 9 on the outer wall of the flushing pipe 5, the depth of the adjustment groove 9 decreasing from top to bottom.

[0043] An annular protrusion 10 is integrally formed on the inner wall of the sleeve 8. The annular protrusion 10 is sleeved on the outside of the flushing tube 5 and slides in conjunction with the adjusting groove 9. In this embodiment, several scale lines are engraved on the side wall of the flushing tube 5, and the values ​​of the scale lines gradually increase from top to bottom. The flushing tube 5 is made of silicone material, which gives the flushing tube 5 a certain deformation capability.

[0044] The sleeve 8 is equipped with a protective component that automatically reduces the pressure of the flushing pipe 5 when the pressure of the flushing pipe 5 is too high.

[0045] The base 1 is equipped with a collection component for collecting cleaning waste liquid.

[0046] The flushing pipe 5 is connected to a first solenoid valve 24, and the controller is used to control the opening and closing of the first solenoid valve 24. The perianal flushing branch pipe 25 is fixedly connected to the side wall of the bracket 2 by screws. The perianal flushing branch pipe 25 is connected to the connecting pipe 7. The perianal flushing branch pipe 25 is connected to a second solenoid valve, and the controller is used to control the opening and closing of the second solenoid valve.

[0047] Combination Figure 2 As shown, when rectal irrigation is required, the patient sits on the support 4. Medical staff determine the insertion depth of the irrigation tube 5 according to the patient's clinical needs (such as the type of surgery). Since the irrigation tube 5 slides on the inner wall of the sleeve 8, the operator holds the sleeve 8 with one hand and pulls the irrigation tube 5 upward with the other hand. The length of the part of the irrigation tube 5 protruding from the sleeve 8 is adjusted by the scale line, which is the preset insertion depth of the irrigation tube 5 into the rectum. If a 2cm insertion depth is selected, the irrigation tube 5 is pulled so that the top of the sleeve 8 is aligned with the scale line on the irrigation tube 5 to the 2cm position. At this time, the pressure of the annular protrusion 10 on the side wall of the irrigation tube 5 is small, the contraction amplitude of the irrigation tube 5 wall is small, and the flow rate of the irrigation fluid flowing through the irrigation tube 5 is large. This is suitable for the function of large-flow irrigation of the rectal part close to the anus.

[0048] If an insertion depth of 5cm is selected, pull the flushing tube 5 so that the top of the sleeve 8 is aligned with the scale line on the flushing tube 5 to the 5cm position. As the depth of the adjusting groove 9 decreases from top to bottom, the pressure of the annular protrusion 10 on the side wall of the flushing tube 5 increases, the contraction amplitude of the flushing tube 5 wall increases, and the diameter of the flushing tube 5 decreases. This reduces the flow rate of the flushing fluid flowing through the flushing tube 5, thus avoiding the safety accident of damage to the deep rectum caused by excessive flow. At the same time, according to Bernoulli's principle, the flow velocity of the flushing fluid above the flushing tube 5 increases, so the flow velocity of the flushing fluid sprayed from the flushing port increases. This fast flow rate and low flow rate flushing method can more effectively flush feces or secretions deep in the rectum. At the same time, due to the reduction in overall flow rate, the total amount of fluid entering the intestine per unit time is controlled, reducing the risk of intestinal over-distension and perforation.

[0049] Subsequently, the irrigation tube 5 is inserted into the patient's rectum. When the irrigation tube 5 is inserted to the preset insertion depth in the rectum, the cannula 8 can prevent the irrigation tube 5 from continuing to enter, so as to avoid excessive insertion and causing discomfort to the patient. Then, the controller controls the first solenoid valve 24 to open and the second solenoid valve to close, and the controller controls the pump assembly 6 to start. At this time, the pump assembly 6 pumps the irrigation fluid in the reservoir 3 into the irrigation tube 5 through the connecting pipe 7, and then sprays it out from the irrigation port to irrigate the patient's rectum.

[0050] Combination Figure 1 As shown, when it is necessary to rinse the patient's perianal area, the controller opens the second solenoid valve and closes the first solenoid valve 24. At this time, the pump assembly 6 can spray the rinsing fluid from the connecting pipe 7 and then from the perianal rinsing branch pipe 25 to achieve the effect of rinsing the patient's perianal area.

[0051] like Figure 1 and Figure 4 As shown, specifically, the collection assembly includes a sewage basin 12 fixedly connected to the bracket 2 by bolts, a collection box 13 fixedly connected to the bottom of the sewage basin 12 by screws, and the collection box 13 fixedly connected to the top of the base 1 by bolts. A drain outlet 14 is opened at the bottom of the sewage basin 12, and the sewage basin 12 and the collection box 13 are connected through the drain outlet 14. An overflow prevention component is provided on the drain outlet 14 to prevent sewage from overflowing from the sewage basin 12.

[0052] like Figure 4 As shown, specifically, the overflow prevention component includes a plug 21 hinged to the bottom wall of the sewage basin 12, a traction rope 11 fixedly attached to the top of the plug 21, and a float 22 fixedly attached to the end of the traction rope 11 away from the plug 21; a drain valve 23 is connected to the side wall of the collection box 13.

[0053] Combination Figure 4As shown, during rinsing, the rinsing wastewater can flow into the wastewater basin 12 for collection. The float 22 can float on the surface of the liquid. At this time, because the plug 21 covers the drain outlet 14, the wastewater cannot flow into the collection tank 13. The wastewater level in the wastewater basin 12 gradually rises, so the float 22 gradually rises, tauting the traction rope 11. When the liquid level in the wastewater basin 12 is about to overflow, the float 22 pulls the traction rope 11, which in turn drives the plug 21 to open the drain outlet 14, allowing the wastewater to flow into the collection tank 13 and preventing the wastewater from overflowing from the wastewater basin 12.

[0054] like Figure 2 and Figure 3 As shown, specifically, the protection assembly includes a conduit 15 symmetrically connected to the side wall of the flushing pipe 5, and an "L"-shaped channel 16 symmetrically opened inside the side wall of the sleeve 8; the end of the conduit 15 away from the flushing pipe 5 is connected to its adjacent channel 16; a piston 17 is slidably fitted inside the transverse end of each channel 16, and a tension spring 18 is fixedly connected to each piston 17 by screws, and the end of the tension spring 18 away from the piston 17 is fixedly connected to the inner side wall of its adjacent channel 16 by screws; a connecting rod 19 is integrally formed on each piston 17, and the end of the connecting rod 19 away from the piston 17 extends into the sleeve 8 and is integrally formed with a clamping block 20.

[0055] When the patient's rectum is irrigated, some of the irrigating fluid enters the catheter 15 and then the channel 16. At this time, the pressure of the irrigating fluid is within the normal range. This pressure is less than the tension of the spring 18. Therefore, the piston 17 remains in place, and the clamping block 20 at one end of the connecting rod 19 maintains slight contact with the outer wall of the irrigating tube 5, without producing additional clamping effect.

[0056] If an abnormal situation occurs, such as when the patient's intestinal spasm causes an increase in the pressure at the flushing port, or when the output pressure of the pump assembly 6 fluctuates, and the pressure of the flushing fluid in the flushing tube 5 exceeds the tension of the spring 18, the pressure of the flushing fluid can push the left piston 17 to move to the right and the right piston 17 to move to the left, driving the connecting rod 19 to drive the clamping block 20 to move towards the axis of the flushing tube 5, clamping the wall of the flushing tube 5 which is already in a contracted state due to the compression of the annular protrusion 10.

[0057] The clamping block 20 further compresses the flow cross-section of the flushing fluid in the flushing tube 5, thereby further reducing the flow rate of the fluid that can pass through the flushing tube 5 and preventing damage to the patient's rectal mucosa.

[0058] This solution enables adaptive flow rate adjustment. When the pressure inside the flushing tube 5 is too high, the protection component automatically triggers to reduce the flow orifice diameter to release pressure, preventing high pressure damage to the mucosa. This eliminates the need for manual judgment and adjustment by medical personnel, solving the problem of mismatch between insertion depth and flow rate in existing equipment, reducing the risk of mucosal damage due to lack of experience, and improving the safety of the flushing operation.

[0059] Example 2:

[0060] As attached Figure 1 As shown, the difference from Embodiment 1 is that a back plate 26 is bolted to the side wall of the support 2, and a flexible pad is fixedly adhered to the side wall of the back plate 26. The back plate 26 provides support for the patient, and the flexible pad conforms to the patient's body curves, improving the patient's positional comfort during irrigation.

[0061] Example 3:

[0062] As attached Figure 1 As shown, the difference from Embodiment 2 is that handrails 27 are symmetrically fixed to the side wall of the support 2 by bolts. The symmetrical handrails 27 make it easier for the patient to grasp and maintain a stable position, reducing the risk of displacement of the irrigation tube 5 and mucosal damage caused by body shaking during the irrigation process.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
