Description

Technical Field

[0001] This invention relates to a flushing device, and more particularly to a medical urological urinary tract anesthesia flushing device. Background Technology

[0002] A medical urological urinary tract anesthesia irrigation device is a medical device specifically designed for use in urological surgeries. Its main functions include local anesthesia and irrigation of the urethra, bladder, and other areas to ensure patient comfort during procedures and reduce the risk of infection.

[0003] In urological surgery, urinary tract irrigation under anesthesia is a key step in reducing patient pain. However, traditional procedures have significant drawbacks: the injection of anesthetic (such as lidocaine gel) and subsequent irrigation must be completed in separate steps. Medical staff must first inject the anesthetic separately and wait for it to take effect before connecting the irrigation device to perform the irrigation. This process is cumbersome and significantly prolongs the operation time. At the same time, the anesthetic is easily diluted or washed away from the site of action by the subsequent irrigation fluid, resulting in unstable anesthetic effects. Furthermore, the unheated irrigation fluid comes into direct contact with the urethral mucosa, which can easily cause urethral spasms and severe discomfort in patients. Summary of the Invention

[0004] In order to overcome the significant defects of traditional operation in the above-mentioned background technology, which requires the injection of anesthetic and subsequent flushing to be completed in steps, the purpose of this invention is to provide a medical urological urinary tract anesthesia flushing device.

[0005] The technical solution of this invention is: a medical urological urinary tract anesthesia irrigation device, comprising a base, an electric telescopic rod, a heater, an irrigation fluid storage tank, a mixing tank, a frame, a guide tube, a contact block, a frame-type push rod, a piston rod, a piston tube, an anesthetic fluid storage tube, an elastic element, a dual-axis extension motor, a large stirring paddle, and a cam. An electric telescopic rod is installed on the top left side of the base, and a heater is connected to the top of the electric telescopic rod. An irrigation fluid storage tank is installed inside the heater, and a large stirring paddle is rotatably connected to the bottom of the irrigation fluid storage tank. A dual-axis extension motor is installed at the top of the electric telescopic rod, and a cam is located on the upper side of the dual-axis extension motor. The output shaft is connected to the large stirring paddle. A cam is provided on the lower output shaft of the dual-shaft extension motor. A mixing tank is connected to the front of the bottom of the flushing liquid storage tank. A liquid guide pipe is connected to the bottom of the mixing tank. A piston tube is connected to the upper front of the mixing tank. A piston rod is provided inside the piston tube. Sleeves are provided on both the left and right sides of the piston tube and the mixing tank. A frame-shaped push rod is slidably connected to the sleeve. Elastic elements are sleeved on both the left and right sides of the frame-shaped push rod. The rear ends of the two elastic elements are connected to the two rear sleeves. The front side of the frame-shaped push rod is connected to the front end of the piston rod. A contact block is connected to the rear side of the frame-shaped push rod. The contact block abuts against the cam.

[0006] Furthermore, it also includes a connecting rod, a rack, a gear, and a micro-stirring paddle. The connecting rod is sleeved on the right side of the frame-shaped push rod, and a rack is connected to the lower left end of the connecting rod. A micro-stirring paddle is rotatably connected to the lower side of the mixing tank. The shaft of the micro-stirring paddle is installed at the lower outlet of the mixing tank, and a gear is sleeved on the outside of the shaft of the micro-stirring paddle. The gear and the rack mesh with each other.

[0007] Furthermore, it also includes a frame, a waste liquid tank, a peristaltic pump, and a waste liquid pipe. The top front of the base is connected to the frame, the waste liquid tank is placed inside the frame, the waste liquid pipe is placed inside the waste liquid tank, the upper rear of the frame is connected to the peristaltic pump, and the upper side of the waste liquid pipe is snapped into the peristaltic pump.

[0008] Furthermore, it also includes a push rod and a rubber sleeve. The base is an L-shaped plate, with a push rod connected to the upper right end of the base, and a rubber sleeve fitted onto the upper right side of the push rod.

[0009] Furthermore, it also includes a medicine box and drawers. The medicine box is connected to the top right side of the base, and drawers are arranged at intervals from top to bottom inside the medicine box. The drawers are slidably connected to the medicine box.

[0010] Furthermore, it also includes a baffle. The top of the medicine box is equipped with a baffle, and both the front and rear ends of the baffle have arc-shaped notches.

[0011] Furthermore, it also includes a transparent glass plate and graduations. The front end of the anesthetic fluid storage tube is equipped with a transparent glass plate with graduations engraved on it, and the size of the graduations gradually increases from bottom to top.

[0012] Furthermore, it also includes a threaded cap and a protective plate. The top inlet of the flushing fluid storage tank is threaded with a threaded cap, and the upper front end of the mixing tank is connected with a protective plate, which covers the top of the frame-shaped push rod.

[0013] Furthermore, it also includes a control panel and a control valve. The control panel is located at the rear end of the heater, and a control valve is installed at the liquid inlet on the upper side of the mixing tank. The control valve is electrically connected to the control panel.

[0014] Furthermore, it also includes casters, with casters installed at each of the four corners of the base.

[0015] The beneficial effects are: 1. This invention sets a cam to drive the frame-shaped push rod to move back and forth, the frame-shaped push rod drives the piston rod to draw the anesthetic fluid from the anesthetic fluid storage tube in the piston tube, and pushes the anesthetic fluid into the mixing tank. By rotating the micro stirring paddle, the anesthetic fluid is quickly mixed with the constant temperature flushing fluid in the mixing tank. The mixed solution is then used to flush the patient's urinary tract, eliminating the waiting step in the traditional step-by-step operation.

[0016] 2. The heater continuously heats the flushing fluid in the storage tank at a constant temperature, and the large stirring paddle rotates at low speed to achieve a uniform temperature across the entire range, ensuring that the flushing fluid is always kept close to body temperature, thus avoiding urethral spasms and patient discomfort caused by cold stimulation.

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] A medical urological urinary tract anesthesia irrigation device, such as Figures 1-8As shown, the system includes a base 1, an electric telescopic rod 3, a heater 4, a flushing fluid storage tank 6, a mixing tank 7, a frame 71, a fluid guide tube 702, a contact block 7021, a frame-type push rod 703, a piston rod 7031, a piston tube 704, an anesthetic fluid storage tube 705, an elastic element 706, a dual-shaft extension motor 8, a large stirring paddle 801, and a cam 802. The electric telescopic rod 3 is mounted on the top left side of the base 1, and the heater 4 is connected to the top of the electric telescopic rod 3. The flushing fluid storage tank 6 is installed inside the heater 4, which is used for heating. The flushing liquid is stored in a heat-insulating flushing liquid storage tank 6, which is used to store the flushing liquid to be heated and used. A large stirring paddle 801 is rotatably connected to the bottom of the flushing liquid storage tank 6. A dual-shaft extension motor 8 is installed at the top of the electric telescopic rod 3. The upper output shaft of the dual-shaft extension motor 8 is connected to the large stirring paddle 801. A cam 802 is provided on the lower output shaft of the dual-shaft extension motor 8. The lower output shaft of the dual-shaft extension motor 8 is rotatably connected to the push rod of the electric telescopic rod 3. A mixing tank 7 is connected to the front of the bottom of the flushing liquid storage tank 6. The mixing tank 7 is used to receive a mixed solution of rinsing fluid and anesthetic fluid. A guide pipe 702 is connected to the bottom of the mixing tank 7, which is used to discharge the mixed solution of rinsing fluid and anesthetic fluid. A piston pipe 704 is connected to the upper front of the mixing tank 7. A piston rod 7031 is installed inside the piston pipe 704. Sleeves 71 are provided on both the left and right sides of the piston pipe 704 and the mixing tank 7. A frame-type push rod 703 is slidably connected to the sleeve 71. Elastic elements 706 are sleeved on both sides of the frame-type push rod 703. The rear ends of both elastic elements 706... The frame-shaped push rod 703 is connected to the front end of the piston rod 7031 and the front end of the frame-shaped push rod 703 is connected to the rear end of the frame-shaped push rod 703. The contact block 7021 abuts against the cam 802. The frame-shaped push rod 703 reciprocates under the action of the cam 802 and the elastic element 706. The piston rod 7031 follows the movement of the frame-shaped push rod 703. The piston rod 7031 generates negative pressure in the piston tube 704 to draw in the anesthetic liquid and then pushes the anesthetic liquid out, causing it to fall into the mixing tank 7.

[0028] like Figure 6 and Figure 7 As shown, it also includes a connecting rod 707, a rack 708, a gear 709, and a micro-stirring paddle 710. The connecting rod 707 is sleeved on the right side of the frame-shaped push rod 703. The rack 708 is connected to the lower left end of the connecting rod 707. The micro-stirring paddle 710 is rotatably connected to the lower side of the mixing tank 7. The shaft of the micro-stirring paddle 710 is installed at the lower outlet of the mixing tank 7. The gear 709 is sleeved on the outside of the shaft of the micro-stirring paddle 710. The gear 709 and the rack 708 mesh with each other. During the reciprocating movement of the frame-shaped push rod 703, it drives the rack 708 to move. The rack 708 causes the gear 709 to rotate. The gear 709 drives the micro-stirring paddle 710 to rotate.

[0029] like Figure 1 , Figure 2 and Figure 8 As shown, it also includes a frame 5, a waste liquid tank 501, a peristaltic pump 502, and a waste liquid pipe 5021. The top front of the base 1 is connected to the frame 5, and the waste liquid tank 501 is placed inside the frame 5. The waste liquid tank 501 is used to collect waste liquid after flushing the patient's urinary tract. The waste liquid pipe 5021 is placed inside the waste liquid tank 501 and is used to transport waste liquid. The peristaltic pump 502 is connected to the upper rear end of the frame 5. The upper side of the waste liquid pipe 5021 is snapped into the peristaltic pump 502. The peristaltic pump 502 provides power to draw the waste liquid through the waste liquid pipe 5021 into the waste liquid tank 501.

[0030] like Figure 1 and Figure 2 As shown, it also includes a push rod 102, a rubber sleeve 103, a medicine box 2, a drawer 201, and a baffle 202. The base 1 is an L-shaped plate. The push rod 102 is connected to the upper right end of the base 1. The rubber sleeve 103 is fitted onto the upper right side of the push rod 102. The rubber sleeve 103 provides a comfortable grip and is non-slip. The medicine box 2 is connected to the top right side of the base 1. Drawers 201 are arranged sequentially from top to bottom inside the medicine box 2. The drawers 201 are slidably connected inside the medicine box 2. The drawers 201 inside the medicine box 2 can be used to store consumables. A baffle 202 is provided at the top of the medicine box 2. Both the front and rear ends of the baffle 202 have arc-shaped notches, which can be used to temporarily place medical instruments on the top of the medicine box 2. The baffle 202 can prevent medical instruments from falling. The arc-shaped notches on the baffle 202 are conducive to medical staff gripping and using medical instruments.

[0031] like Figure 2 , Figure 4 and Figure 6 As shown, it also includes a threaded cap 601, a protective plate 701, a transparent glass plate 7051, and a scale 7052. The top inlet of the flushing fluid storage tank 6 is threaded with a threaded cap 601. The upper front end of the mixing tank 7 is connected to a protective plate 701, which covers the top of the frame-shaped push rod 703. The protective plate 701 serves to protect the frame-shaped push rod 703. The front end of the anesthetic fluid storage tube 705 is provided with a transparent glass plate 7051, on which a scale 7052 is engraved. The size of the scale 7052 gradually increases from bottom to top. The transparent glass plate 7051, together with the scale 7052, can monitor the remaining amount of anesthetic fluid.

[0032] like Figure 1 , Figure 3 and Figure 7As shown, it also includes casters 101, control panel 401 and control valve 9. Casters 101 are installed on the four corners of the bottom of the base 1. Control panel 401 is provided at the rear end of the heater 4. Control valve 9 is installed at the liquid inlet on the upper side of the mixing tank 7. Control valve 9 is electrically connected to control panel 401. This device moves by pulling push rod 102, which causes the casters 101 at the bottom to rotate, thereby moving the entire device.

[0033] When using this device, medical staff first add flushing fluid to the flushing fluid storage tank 6, then activate the heater 4 via the control panel 401 and set the heating temperature, so that the flushing fluid in the flushing fluid storage tank 6 is heated to the set temperature. During this process, the heater 4 keeps the flushing fluid in the flushing fluid storage tank 6 warm. The anesthetic fluid is then loaded into the anesthetic fluid storage tube 705. A disposable catheter (not shown in the diagram) is connected to the lower outlet of the guide tube 702. This catheter allows the flushing fluid to be discharged and flushed through the patient's urinary tract. The control valve 9 is opened on the control panel 401, causing the flushing fluid in the flushing fluid storage tank 6 to automatically fall into the mixing tank 7. At this time, the upper part of the inside of the mixing tank 7 is filled with gas. The lower part contains the flushing fluid. The dual-axis extension motor 8 and the electric telescopic rod 3 are activated. The push rod of the electric telescopic rod 3 rises, causing the heater 4 and the flushing fluid storage tank 6 to move to a certain height (this height can be determined based on the height of the medical staff; the height of the anesthetic fluid storage tube 705 should be similar to the height of the medical staff). The upper output shaft of the dual-axis extension motor 8 drives the large stirring paddle 801 to rotate. The large stirring paddle 801 slowly stirs the flushing fluid to stabilize its internal temperature. Simultaneously, the lower output shaft of the dual-axis extension motor 8 drives the cam 802 to rotate. The outer surface of the cam 802 is always in contact with the contact block 7021. When the contact surface between the contact block 7021 and the cam 802 gradually changes from the proximal end to the distal end of the cam 802, the convex... Under the pressure of wheel 802, frame-shaped push rod 703 moves forward and compresses the elastic elements 706 on both sides. The elastic elements 706 on both sides change from the initial state to the compressed state. Frame-shaped push rod 703 drives piston rod 7031 to move forward, creating a negative pressure in the cavity behind piston tube 704. The anesthetic fluid in anesthetic fluid storage tube 705 is drawn into piston tube 704. When the contact surface between contact block 7021 and cam 802 gradually changes from the distal end to the proximal end of cam 802, the two elastic elements 706 gradually reset. The reset of elastic elements 706 pushes frame-shaped push rod 703 backward, driving piston rod 7031 to push anesthetic fluid into mixing tank 7. The anesthetic fluid will slide down along the inner wall of mixing tank 7 and mix with flushing fluid. During this process, frame... The rack 708 connected to the right side of the push rod 703 moves back and forth, driving the gear 709, which is coaxial with the micro-stirring paddle 710, to rotate in both directions. The micro-stirring paddle 710 rotates continuously, stirring the constant temperature rinsing fluid and anesthetic fluid in the mixing tank 7 to ensure thorough mixing. Under the action of gravity, the mixed constant temperature anesthetic rinsing fluid is output through the guide tube 702 to the external catheter for further rinsing of the patient. The left inlet of the waste fluid pipe 5021 is connected to the corresponding drain pipe (this drain pipe is not shown in the figure; it is used to drain the anesthetic rinsing fluid after urinary tract flushing). The peristaltic pump 502 is started, which accelerates the discharge of the anesthetic rinsing fluid after flushing. The waste fluid pipe 5021 guides the anesthetic rinsing fluid discharged by the patient into the waste fluid tank 501.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
