Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to a rotary bladder irrigation device. Background Art

[0002] In modern medicine, bladder irrigation is a common treatment method mainly used to remove impurities, pus, infectious substances, etc. in the bladder. However, existing bladder irrigation devices still have many deficiencies in performance and operation, which limit their application effects in clinical practice.

[0003] Firstly, existing bladder irrigation devices usually require multiple valves and branches to achieve the injection and extraction of liquid into and from the bladder. However, in actual use, they are complex and cumbersome. Since medical staff need to switch between multiple pipelines and master the specific operations of each valve, a slight oversight may lead to misoperation, and even cause patient infection or other iatrogenic injuries. Especially in emergency and high-pressure clinical environments, the operation of multiple valves is extremely prone to misoperation, increasing the risk of treatment.

[0004] Secondly, a single medical staff often feels unable to cope when operating existing irrigation equipment. When multiple valves need to be controlled simultaneously, two people are often required to cooperate. However, in busy medical work, there may be a shortage of staff at any time, which limits the effectiveness of the irrigation process and further affects the patient's recovery process.

[0005] In addition, existing bladder irrigation devices often occupy a large amount of space, causing certain inconvenience for their storage and movement, and are difficult to operate during use.

[0006] Therefore, in view of the structure and operation mode of existing bladder irrigation devices, a more user-friendly, simple and effective solution is urgently needed. Summary of the Invention

[0007] The present invention provides a rotary bladder irrigation device, which can overcome the defects of complex operation and large occupied space of existing bladder irrigation devices.

[0008] The bladder irrigation device according to the present invention includes a straight and transparent housing. An installation cavity is formed along the axial direction of the housing. One end of the installation cavity forms an insertion port. A piston assembly that moves axially is provided in the installation cavity. The piston assembly includes a piston body and a distribution part. The piston body includes a piston head that fits against the side wall of the installation cavity. A support rod is provided at one axial end of the piston head. The distribution part is sleeved on the support rod and is rotationally matched with the support rod. A distribution plate is formed at one end of the distribution part close to the piston head. Three connection heads are provided along the circumferential direction at one end of the distribution plate away from the piston head. The three connection heads are respectively connected with a flushing liquid container, a pure water container, and a waste liquid container by hoses. The connection head forms a first flow channel along the axial direction. The piston head correspondingly forms a through second flow channel along the axial direction. A communication end is formed along the axial direction at the bottom of the housing. The communication end forms a through hole communicating with the installation cavity along the axial direction. A swivel joint is provided at the through hole. A catheter is provided at one end of the swivel joint away from the housing. The catheter is used to be inserted into the bladder of a patient. A liquid stop clip or a ball valve is provided at one end of the catheter close to the swivel joint.

[0009] In at least one embodiment of the present invention, the distribution part forms a sleeve along the axial direction. The sleeve is used for sliding cooperation with the support rod. A plurality of anti-slip ribs arranged along the axial direction are formed on the outer side of the sleeve.

[0010] In at least one embodiment of the present invention, a rotation handle is provided on the side of the support rod away from the piston head. The rotation handle is sleeved on the support rod. The rotation handle is in abutting cooperation with the distribution part. A ball head nut is provided on the side of the rotation handle away from the distribution part. A spring washer is sleeved on the support rod. The spring washer is in abutting cooperation with the ball head nut and the rotation handle respectively.

[0011] In at least one embodiment of the present invention, a threaded section and a hexagonal prism section are sequentially formed at one end of the support rod away from the piston head. The threaded section is used for threaded cooperation with the ball head nut. A through hexagonal hole is correspondingly formed at the rotation handle. The hexagonal hole is used for corresponding cooperation with the hexagonal prism section.

[0012] In at least one embodiment of the present invention, the connection head is sequentially provided with a fitting section, an installation section, and a fixing section along the axial direction. The fitting section is used for cooperation with the hose. A first protrusion is formed along the circumferential direction at the fitting section. A metal clamp or a plastic clamp is sleeved on the outer wall of the hose between the first protrusion and the installation section. The installation section is in the shape of a hexagonal prism and is used for cooperation with a wrench. The fixing section is used for threaded cooperation with the piston head. A washer is provided on the side of the fixing section close to the piston head.

[0013] In at least one embodiment of the present invention, an installation groove is formed on the side wall of the piston head. A sealing rubber ring is sleeved at the installation groove. A clamping block that is in imitation cooperation with the installation groove is formed on the inner wall of the sealing rubber ring.

[0014] In at least one embodiment of the present invention, the adapter is formed with an insertion section, a locking section and a connecting section in sequence along the axial direction, and a third flow channel is formed through the adapter along the axial direction. The insertion section is used to cooperate with the through hole thread, and the locking section is a hexagonal column. The locking section forms a baffle near one end of the insertion section, and the baffle is used to abut against the connecting end. One end of the conduit is sleeved on the connecting section, and a second protrusion is formed at the connecting section along the circumferential direction.

[0018] The beneficial effects of the embodiments of the present invention are: First, the bladder flushing device provided by the present invention integrates multiple liquid channels and valve functions through a rotary design, reducing the complexity of multiple pipelines. The operator only needs to perform simple rotation operations to achieve the injection of flushing liquid, the discharge of waste liquid, and the infusion of pure water, which greatly reduces the risk of misoperation. This simplified operation method is particularly important in emergency and high-pressure clinical environments, and can improve the work efficiency of medical staff and ensure that patients receive timely and effective treatment.

[0019] Second, the bladder flushing device of the present invention only requires one person to easily control the flushing process, and no longer requires the cooperation of multiple people. This solves the problem of insufficient manpower in actual work, improves applicability and operability, and enables medical staff to quickly complete bladder flushing in emergency situations.

[0020] Third, the transparent shell design enables medical staff to intuitively observe the state of the liquid inside the installation cavity, which is convenient for real-time monitoring of flushing effects and adjustment operations.

[0027] The drawings in this disclosure are not drawn strictly to actual scale, and the specific dimensions and quantities of each structure can be determined according to actual needs. The drawings described in this disclosure are only schematic diagrams of the structures.

[0028] Referring to Figures 1 to 9 , the following are detailed embodiments of the present invention.

[0029] The rotary bladder irrigation device of this embodiment includes a straight and transparent housing 1. The housing 1 forms an installation cavity 11 along the axial direction. One end of the installation cavity 11 forms an insertion port 12. A piston assembly 2 that moves axially is provided in the installation cavity 11. A communication end 13 is formed along the axial direction at the bottom of the housing 1. A through hole 131 communicating with the installation cavity 11 is formed along the axial direction at the communication end 13. A swivel joint 4 is provided at the through hole 131. A catheter 5 is provided at one end of the swivel joint 4 away from the housing 1. The catheter 5 is used to be inserted into the bladder of the patient. A liquid stop clamp is provided at one end of the catheter 5 close to the swivel joint 4. When the piston assembly 2 moves axially in the installation cavity 11, it can change the liquid volume in the installation cavity 11 and is communicated with the bladder of the patient through the catheter 5, so as to realize injecting or extracting the liquid in the bladder of the patient, and further realize the irrigation of the bladder of the patient.

[0030] It can be understood that in some embodiments, the liquid stop clamp can be replaced by a ball valve 6 to control the flow and cut-off of the liquid flowing out of the catheter 5.

[0031] Among them, the piston assembly 2 includes a piston body 21 and a distribution part 22. The piston body 21 includes a piston head 211 that fits against the side wall of the installation cavity 11. At one axial end of the piston head 211, there is a support rod 212. The distribution part 22 is sleeved at the support rod 212 and is rotationally matched with the support rod 212. One end of the distribution part 22 close to the piston head 211 forms a distribution plate 221. Along the circumference at the end of the distribution plate 221 away from the piston head 211, there are 3 connectors 3. The three connectors 3 are respectively connected to a flushing solution container, a pure water container, and a waste liquid container by hoses. The connector 3 forms a first flow channel 34 along the axis. The piston head 211 correspondingly forms a through second flow channel 213 along the axis. By using the three connectors 3 to connect different containers respectively, the liquid communication between the three different containers and the installation cavity 11 can be realized. The operator only needs to rotate the distribution part 22 to switch different first flow channels 34, and then cooperate with the liquid stop clamp or the ball valve 6 to realize the operation of injecting flushing solution into the patient's bladder, injecting pure water, or discharging waste liquid. All these operations can be carried out by a single person without external assistance, thus improving the work efficiency of the operator.

[0032] Specifically, when it is necessary to inject flushing solution into the patient's bladder, rotate the distribution part 22 to connect the first flow channel 34 communicating with the flushing solution container with the second flow channel 213. Close the liquid stop clamp or the ball valve 6 at the catheter 5, and pull the piston assembly 2 in the direction away from the communication end 13, then the flushing solution can be drawn into the installation cavity 11. When an appropriate amount of flushing solution is drawn, rotate the distribution part 22 to make the second flow channel 213 abut against the distribution plate 221, so as to close the second flow channel 213, and open the liquid stop clamp or the ball valve 6. At this time, push the piston assembly 2 in the direction close to the communication end 13, and the flushing solution can be injected into the patient's bladder. The operation of injecting pure water is the same as that of injecting flushing solution, so it will not be elaborated here.

[0033] When it is necessary to discharge the waste liquid in the patient's bladder, keep the state where the second flow channel 213 abuts against the distribution plate 221 to close the second flow channel 213, and keep the liquid stop clamp or the ball valve 6 open. Pull the piston assembly 2 in the direction away from the communication end 13 to draw the waste liquid in the patient's bladder into the installation cavity 11. Then close the liquid stop clamp or the ball valve 6, and rotate the distribution part 22 to connect the first flow channel 34 communicating with the waste liquid container with the second flow channel 213. Push the piston assembly 2 in the direction close to the communication end 13, and the waste liquid in the installation cavity 11 can be discharged into the waste liquid container through the hose. Repeat the above operation to drain all the waste liquid in the patient's bladder, thereby discharging the impurities, congestion, or pus in the patient's bladder and promoting the patient's cure and the recovery of bladder function.

[0034] With the above structure, when extracting the waste liquid in the patient's bladder, compared with the existing balloon extraction, this solution can accurately control the volume of the liquid flowing out of the bladder, thereby avoiding the negative pressure contraction of the bladder caused by excessive extraction, thus better protecting the patient and reducing the treatment pain.

[0035] Furthermore, a bump extending towards the first flow channel 34 is formed at one end of the second flow channel 213 close to the distribution plate 221. Therefore, when switching between the second flow channel 213 and different first flow channels 34, it can be clamped into the first flow channel 34, which can not only effectively prevent leakage, but also better improve the feel of switching between different flow channels, so as to facilitate the operator to sense whether the flow channel is switched in place.

[0036] In some embodiments, the distribution part 22 forms a sleeve 222 along the axial direction. The sleeve 222 is used for sliding cooperation with the support rod 212. A plurality of anti-slip edges 2221 arranged along the axial direction are formed on the outer surface of the sleeve 222, which is convenient for the operator to hold, so as to facilitate the relative rotation of the distribution part 22 and the piston body 21.

[0037] In some embodiments, a rotating handle 214 is provided on the side of the support rod 212 away from the piston head 211. The rotating handle 214 is sleeved on the support rod 212. The rotating handle 214 abuts against the distribution part 22. A ball head nut 215 is provided on the side of the rotating handle 214 away from the distribution part 22. A spring washer (not shown in the figure) is sleeved on the support rod 212. The spring washer abuts against the ball head nut 215 and the rotating handle 214 respectively.

[0038] Furthermore, a threaded section 2121 and a hexagonal prism section 2122 are sequentially formed at one end of the support rod 212 away from the piston head 211. The threaded section 2121 is used for threaded cooperation with the ball head nut 215. A through hexagonal hole 2141 is correspondingly formed at the rotating handle 214. The hexagonal hole 2141 is used for corresponding cooperation with the hexagonal prism section 2122.

[0039] With the above structure, the fixed cooperation between the rotating handle 214 and the support rod 212 is realized. Thus, the operator can hold the sleeve 222 and rotate the rotating handle 214 at the same time to realize the relative rotation of the distribution part 22 and the piston body 21, and further realize the connection and switching between the second flow channel 213 and different first flow channels 34.

[0040] In some embodiments, the connector 3 is axially provided with a mating section 31, a mounting section 32, and a fixing section 33 in sequence. The mating section 31 is used to mate with the hose. A first protrusion 311 is formed circumferentially at the mating section 31. A metal clamp or a plastic clamp is sleeved on the outer wall of the hose between the first protrusion 311 and the mounting section 32. The mounting section 32 is in the shape of a hexagonal prism and is used to mate with a wrench, facilitating the installation of the connector 3 using the wrench. The fixing section 33 is used to threadedly mate with the piston head 211. A threaded hole for mating with the fixing section 33 is correspondingly provided at the piston head 211. A washer is provided on one side of the fixing section 33 close to the piston head 211, and the washer can enhance the connection strength and sealing performance between the connector 3 and the piston head 211.

[0041] In some embodiments, an installation groove 216 is formed on the side wall of the piston head 211. A sealing rubber ring 217 is sleeved at the installation groove 216. A clamping block 2171 that is in imitation mating with the installation groove 216 is formed on the inner wall of the sealing rubber ring 217, thereby realizing the fixed mating between the sealing rubber ring 217 and the installation groove 216.

[0042] It can be understood that the material of the sealing rubber ring 217 is rubber, and the installation groove 216 can be a square groove or a dovetail groove.

[0043] In some embodiments, the adapter 4 axially forms an insertion section 41, a locking section 42, and a connection section 43 in sequence. The adapter 4 axially forms a through third flow channel 44. The insertion section 41 is used to threadedly mate with the through hole 131. The locking section 42 is in the shape of a hexagonal prism. A retaining piece 421 is formed at one end of the locking section 42 close to the insertion section 41, and the retaining piece 421 is used to abut and mate with the communication end 13. One end of the conduit 5 is sleeved at the connection section 43. A second protrusion 411 is formed circumferentially at the connection section 43. A metal clamp or a plastic clamp is provided on the outer wall of the conduit 5 between the second protrusion 411 and the locking section 42.

[0044] In some embodiments, the conduit 5 is made of semi-rigid transparent plastic, and a rounded corner is formed at one end of the conduit 5 away from the adapter 4, thereby effectively reducing the pain of inserting the conduit 5 into the patient's body.

[0045] In some embodiments, scales are axially formed on the outer wall of the housing 1, and the operator can precisely control the injection and extraction of the liquid in the bladder during use, thereby realizing precise bladder irrigation operations.

[0046] As shown in Figure 10 , at least one embodiment of the present invention further provides a usage method of a rotary bladder irrigation device, which includes steps S1 - S9.

[0047] Step S1: Insert the conduit 5 into the patient's bladder through the patient's urinary catheter.

[0048] Specifically, by aligning the catheter 5 with the patient's urethral orifice, slowly insert the catheter 5 and make it gradually advance through the urinary catheter until there is liquid leakage, indicating that it has entered the bladder.

[0049] Step S2: Connect the catheter 5 to the communication end 13 through the adapter 4. At this time, keep the liquid stop clamp or ball valve 6 in the closed state, and connect the three connectors 3 at the distribution plate 221 to the irrigation solution container, purified water container, and waste liquid container respectively.

[0050] At this time, the preparations for performing bladder irrigation on the patient have been completed. The following is the specific irrigation operation.

[0051] Step S3: Hold the sleeve 222 and turn the rotation handle 214 to connect the second flow channel 213 with the first flow channel 34 corresponding to the connected irrigation solution container, and pull the piston assembly 2 to draw 300 ml of irrigation solution.

[0052] Among them, the irrigation solution is 0.9% sodium chloride solution.

[0053] Step S4: Open the liquid stop clamp or ball valve 6, push the piston assembly 2 to inject 300 ml of irrigation solution into the patient's bladder, then close the liquid stop clamp or ball valve 6 and keep it for 5 minutes.

[0054] Saline irrigation can help remove bacteria, pus, and other infectious substances, thus promoting healing.

[0055] Step S5: Hold the sleeve 222 and turn the rotation handle 214 to close the second flow channel 213, open the liquid stop clamp or ball valve 6, pull the piston to draw the waste liquid in the bladder into the installation cavity 11, then close the liquid stop clamp or ball valve 6, hold the sleeve 222 and turn the rotation handle 214 to connect the second flow channel 213 with the first flow channel 34 corresponding to the connected waste liquid container, and push the piston assembly 2 to discharge the waste liquid in the installation cavity 11 into the waste liquid container. Repeat the above operation several times to drain all the waste liquid in the bladder.

[0056] Step S6: Hold the sleeve 222 and turn the rotation handle 214 to connect the second flow channel 213 with the first flow channel 34 corresponding to the connected purified water container, and pull the piston assembly 2 to draw 300 ml of purified water.

[0057] Step S7: Open the liquid stop clamp or ball valve 6, push the piston assembly 2 to inject 300 ml of purified water into the patient's bladder, then close the liquid stop clamp or ball valve 6 and keep it for 5 minutes.

[0058] Step S8: Repeat the operation of Step S5.

[0059] Step S9: Remove the catheter 5 inserted into the patient's bladder to complete the bladder irrigation operation.

[0060] The above has schematically described the present invention and its implementation manners. Such description is not restrictive. What is shown in the embodiments is only a part of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired thereby and, without departing from the gist of the present invention, design, without creative efforts, structural manners and embodiments similar to the technical solution, they shall fall within the protection scope of the present invention.
