Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of urological surgical equipment, in particular to a urinary catheterization device for urological surgical equipment. Background Art
[0002] Urology commonly uses catheters of different materials (such as silicone, PVC, etc.) and specifications, depending on the patient's needs and conditions. In addition, depending on the patient's specific conditions and needs, some special catheterization equipment, such as balloon catheters, may also be required. Different equipment and tools may be suitable for different situations and needs, so appropriate equipment and tools should be selected under the guidance of professionals.
[0003] Electric and manual types of catheterization equipment each have their own advantages. At the same time, electric equipment can usually complete the catheterization process quickly, and mechanical equipment usually has higher operating efficiency and can complete the catheterization operation in a shorter time, thus ensuring the simplicity and speed of the catheterization process. In addition, in some special cases, such as when the patient is in an inconvenient position to use electric equipment, manual catheterization equipment can be more convenient to operate. Manual equipment can also complete some simple catheterization operations well, and can more accurately control various parameters in the catheterization process, such as pressure, flow, etc., thereby ensuring the accuracy and safety of the catheterization process, and the cost is relatively low. Although manual can ensure controllability, in some special occasions, such as when no one is around for a short time, electric control is required for stable control.
[0004] However, in traditional equipment, only electric or manual control is possible, and both cannot be selected and adjusted simultaneously in one device. Summary of the invention
[0005] The object of the present invention is to provide a urinary catheterization device for urology in order to solve the above-mentioned problems.
[0006] The technical solution adopted by the present invention is as follows: a urinary catheterization device for urological surgery, comprising an access tube, an upper surface of the access tube is fixedly connected to an attachment plate, a lower surface of the access tube is fixedly connected to a connecting tube, a lower surface of the connecting tube is fixedly connected to an outlet tube, an outer surface of the access tube is fixedly connected to an air intake pipe, an outer surface of the air intake pipe away from the access tube is fixedly connected to an air intake rubber ball, an outer surface of the air intake rubber ball is movably connected to an adjustment knob, an outer surface of the air intake rubber ball is movably connected to a manual body, an inner surface of the manual body is movably connected to a deformation plate, and an inner surface of the manual body away from the air intake rubber ball is movably connected to an air suction rubber ball.
[0007] By adopting the above technical scheme, the access tube and the attachment plate ensure the adsorption of the corresponding position, ensuring that the device can catheterize smoothly, the connecting tube facilitates the upper end device to be well fixed on the patient, and the lead-out tube facilitates the lead-out tube to have more deformation space to avoid the occlusion of the pipeline caused by the extrusion of the lead-out tube. By pressing the deformation plate, the air intake rubber ball and the air intake rubber ball are squeezed, and a one-way air valve structure is adopted at the adjustment knob. The connection of the air intake opening of the air intake rubber ball is completed by the extension and contraction of the knob, the air intake radius is changed, and the air intake efficiency is adjusted. The air intake rubber ball is discharged through the air intake pipe and the one-way air intake is also used at the access pipe to ensure the normal flow direction of the equipment. The manual main body ensures the normal deformation of the air intake rubber ball, the deformation plate, and the air intake rubber ball and the stability of the relative displacement, which ensures that the liquid flow direction is always in an ideal state and enters the collection box.
[0008] In a preferred embodiment, a guide pipe is fixedly connected to the lower surface of the lead-out pipe, an extension pipe is fixedly connected to the lower surface of the guide pipe, and a three-way connector is fixedly connected to the lower surface of the extension pipe.
[0009] By adopting the above technical solution, the outlet tube guides the patient's urine out, the extension tube can be extended to ensure the introduction of the urinary tract, and the three-way connector ensures the stability of the connection setting of the equipment.
[0010] In a preferred embodiment, a manual urine inlet is fixedly connected to the side surface of the three-way connector, a baffle is movably connected to the outer surface of the manual urine inlet away from the three-way connector, a soft-core silicone pad is fixedly connected to the outer surface of the baffle corresponding to the manual urine inlet, an air pressure buffer box is fixedly connected to the outer surface of the baffle side of the manual urine inlet, and the lower surface of the manual main body is fixedly connected to the air pressure buffer box.
[0011] By adopting the above technical solution, when the three-way connector enters the manual urine inlet, the baffle and the soft-core silicone pad are in sticky contact, and the friction is reduced during liquid lubrication to reduce dripping, and then the urine is sucked into the air pressure buffer box under the deformation of the air-intake rubber ball, and falls under the air pressure buffer box under gravity.
[0012] In a preferred embodiment, a fixing ring is fixedly connected to the inner surface of the connecting tube, and a hard inserting tube is movably connected to the inner surface of the connecting tube corresponding to the fixing ring.
[0013] By adopting the above technical solution, the fixing ring can be pulled out due to the deformation of the fixing ring and the hard cannula when the fixing ring is not in use.
[0014] In a preferred embodiment, a waist fixing strap is fixedly connected to the outer surface of the connecting tube, a Velcro is fixedly connected to the outer surface of the waist fixing strap, and a leg strap is movably connected to the outer surface of the Velcro.
[0015] By adopting the above technical solution, the waist fixing strap can be tied around the waist and fixed with Velcro. The leg straps can also be connected externally and tied to the legs or the trident position to ensure the introduction of the equipment.
[0016] In a preferred embodiment, a nylon strap is fixedly connected to the outer surface of the air pressure buffer box away from the manual urine inlet tube, and a fixing ring is fixedly connected to the outer surface of the nylon strap away from the air pressure buffer box, and a clip is provided on the outer surface of the fixing ring.
[0017] By adopting the above technical solution, the fixing ring and the clip can be conveniently fixed beside the patient, and the manual main body and the air pressure buffer box are fixed by connecting with nylon straps.
[0018] In a preferred embodiment, a fixing strap is fixedly connected to a side surface of the three-way connector, and a fixing plate is fixedly connected to a side surface of the three-way connector.
[0019] By adopting the above technical solution, Velcro is also provided on the outer surface of the fixing strap and the three-way connector to complete the binding of the intake pipe and the extension pipe, while also conveniently fixing the three-way connector. The fixing plate also has built-in holes to facilitate the fixation of the three-way connector.
[0020] In a preferred embodiment, a sealing nut is movably connected to the lower surface of the three-way connector, a connecting threaded tube is movably connected to the lower surface of the three-way connector, a first ventilation tube is movably connected to the inner surface of the connecting threaded tube, and an electric catheter body is fixedly connected to the outer surface of one end of the first ventilation tube away from the connecting threaded tube.
[0021] By adopting the above technical solution, the knob connected to the threaded tube connects the first ventilation tube to the access tube, and the electric catheter body adsorbs the inside of the equipment pipeline through the blower.
[0022] In a preferred embodiment, the outer surface of the electric catheter body is movably connected to a collection box, the upper surface of the collection box is movably connected to a second ventilation pipe, the other end of the second ventilation pipe is fixedly connected to the air pressure buffer box, and the upper surface of the collection box is fixedly connected to a handle.
[0023] By adopting the above technical solution, water needs to be placed in the collection box to block the pipeline at the lower end of the electric catheterization body to avoid backflow. The air pressure buffer box ensures the collection of manual connection. The second ventilation tube pours the liquid collected by the air pressure buffer box into the collection box. By pulling out the second ventilation tube and the electric catheterization body, the handle can be easily picked up to pour out the collected urine.
[0024] In a preferred embodiment, a sealing gasket is fixedly connected to the outer surface of the contact end of the electric catheter body corresponding to the collecting box, and a blower is arranged on the upper surface of the electric catheter body.
[0025] By adopting the above technical solution, the sealing gasket corresponds to the seal of the collection box, so that the three-way connector, the first ventilation tube, and the interior of the electric catheterization body are in a sealed state. The blower completes the blowing and extracts the internal air. The internal urinary tract reaches the electric catheterization body through the first ventilation tube at the three-way connector.
[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0027] In the present invention,
[0028] 1. When accessing, one is to complete the operation, the catheter is in the patient's body, and the access is completed by inserting the hard cannula into the external pipeline. The other is to fix it in the urinary tract by adsorbing the attached disc to the skin near the urinary tract. When the fixing ring is not in use, the deformation of the fixing ring and the hard cannula will pull out the fixing ring. The access tube ensures enough space for adjustment and placement to ensure utilization efficiency. It can be tied to the waist through the waist fixing strap, fixed with Velcro, and can also be fixed by continuing to connect the leg straps externally, tied to the legs or the trident position to ensure the introduction of the device;
[0029] Second, since the hydraulic pressure at the upper end is greater than that at the lower end, the three-way connector and the air pressure buffer box need to be placed at the lower end, and the extension tube can be extended to ensure the introduction of the urinary tract. The three-way connector and the air pressure buffer box are also provided with fixing rings, clips, fixing straps, and fixing plates for easy fixing. When the fixing straps are fixed, the air intake pipe and the extension pipe can be bound at the same time to avoid related problems caused by cluttered lines;
[0030] 3. When there is an electric catheterization body and when there is no electric catheterization body, the device can be used for catheterization by electric and manual methods respectively. The overall principle is simple and the effect is obvious. Through different measures, it is possible to ensure catheterization while completing the balance of internal pipeline air pressure.

The internal urinary tract reaches the electric catheterization body 31 through the first ventilation tube 30 at the three-way connector 14.
[0061] The implementation principle of an embodiment of a urological catheterization device of the present invention is as follows:
[0062] The device provides two connection methods. One is that the operation is completed, the urinary catheter is in the patient's body, and the access is completed by inserting the hard cannula 20 into the external pipeline. The other is that the attachment plate 2 is adsorbed on the skin near the urinary tract to complete the fixation in the urinary tract. When the fixing ring 19 is not in use, the fixing ring 19 and the hard cannula 20 are deformed to pull out the fixing ring 19. The access tube 1 ensures sufficient space for adjustment and placement to ensure utilization efficiency. It can be tied to the waist through the waist fixing strap 21, attached and fixed with Velcro 22, and can also be connected to the leg strap 2 3, tied to the leg or fixed at the trident position to ensure the introduction of the equipment, the urinary tract continues through the outlet tube 12, the extension tube 13, and the three-way connector 14. The hydraulic pressure at the upper end is greater than the hydraulic pressure at the lower end, so the above-mentioned parts need to be gradually placed horizontally and downwardly. When there is no electric catheter body 31, the blocking nut 34 knob blocks the bottom of the three-way connector 14, and the air intake rubber ball 6 and the air suction rubber ball 10 are squeezed by pressing the deformation plate 9. The one-way air valve structure is adopted at the adjustment knob 7, and the air intake opening of the air intake rubber ball 6 is connected by the knob extension. Then, the air intake radius is changed to adjust the air intake efficiency. The air intake rubber ball 6 is discharged through the air intake pipe 5 and the air is also inhaled in one direction at the access pipe 1. When the patient urinates, the urine enters the manual urine inlet tube 15 at the three-way connector 14. The baffle 16 and the soft core silicone pad 17 are in viscous contact. When the liquid is lubricated, the friction force is reduced and the urine drips. Then, the urine is sucked into the air pressure buffer box 18 under the deformation of the air suction rubber ball 10, and falls under the air pressure buffer box 18 under gravity, and continues to be introduced into the collection box 35 through the pipeline in the second ventilation pipe 11. When there is an electric catheter body 3 1, the collection box 35 needs to be placed with water to block the pipeline at the lower end of the electric catheterization body 31 to avoid backflow. The baffle 16 and the soft silicone pad 17 are in sticky contact with the manual urine inlet tube 15 to block it, and the sealing pad 33 corresponds to the seal of the collection box 35, so that the three-way connector 14, the first ventilation pipe 30, and the inside of the electric catheterization body 31 are in a sealed state. The blower 32 completes the blowing and extracts the internal air. The internal urinary tract reaches the electric catheterization body 31 through the first ventilation pipe 30 at the three-way connector 14, and also enters the collection box 35 under the action of gravity.
