Description

Urinary catheterization device

The present invention belongs to the technical field of urinary catheters, and in particular relates to a urinary catheterization device which provides a water balloon for a urinary catheter to perform fluid guiding operations.

In recent years, with the advancement of medical technology, the quality and efficiency of diagnosis or treatment have been greatly improved. Among them, when the patient is unfortunately suffering from a urinary-related disease or needs general anesthesia surgery, in order to help the patient urinate and monitor his urine at the same time, a urinary catheter must be placed in the patient to supplement it. A common catheter is a long-term indwelling catheter, which can be placed in the patient for a period of time, and then the catheter is removed according to the diagnosis result. The urinary catheter is a long-shaped medical appliance. One end of the urinary catheter is placed in the bladder and has a urine introduction port for urine extraction. At the same time, the end has a water balloon to fix the urinary catheter. The medical staff will place one end of the catheter in the patient's bladder, and expand the water balloon through it to allow the catheter to stay in the bladder. The urine bag is connected to the other end of the catheter to facilitate Urine flows into the bladder.

However, the technique of installing a catheter is cumbersome, and the doctor or nurse must actually disinfect and place the catheter in the patient's bladder. Subsequently, the water balloon of the catheter must be inflated to prevent the catheter from slipping out of the patient's body. Among them, after the urinary catheter is placed in the patient's body, the medical staff needs to squeeze the patient's lower abdomen with one hand, and the other hand takes the syringe to drive the fluid into the injection port of the urinary catheter to expand the water balloon, and then remove it. Discard the syringe. And when the urinary catheter is removed, it is still necessary to control the syringe with one hand to suck out the fluid in the water balloon, so that the water balloon retracts to its original state. To remove the catheter from the patient's bladder. In this way, because the catheter must be controlled with one hand to control the state of the water balloon when placing or removing the urinary catheter, it is not easy for the medical staff to operate, and it also requires a lot of syringe consumables, which will increase the hospital or clinic. Burden.

In view of this, the team of the present invention felt that their current practice was not perfect and exhausted their minds and thoughts. Based on their accumulated experience in conducting the research for many years, they finally proposed a urinary catheterization device to improve the above-mentioned conventional techniques. Missing. With this, it can only use this medical device and easily control it with one hand when placing and removing the urinary catheter, so that the water balloon of the urinary catheter is in an inflated or retracted state to facilitate the urinary catheter. To place or remove.

In view of the above problems, the object of the present invention is to provide a urinary catheter infusion device for medical personnel to quickly control the water balloon of the urinary catheter to expand or retract, thereby facilitating the placement or removal of the urinary catheter, and Effectively reduce consumable costs.

To achieve the above object, the present invention provides a urinary catheter infusion device for fluid infusion operation of a water balloon of a urinary catheter, including a body and a threaded joint. In addition, the body has an accommodation space and a plurality of telescopic portions, and the threaded joint is connected to the body and communicates with the accommodation space. Wherein, when the threaded joint is connected and screwed to an injection port of the urinary catheter, the accommodation space and the water balloon are in a connected state, and the telescopic portion is compressed to supply a fluid to the water balloon. Inside; when the threaded joint is connected and unscrewed to the injection port, the accommodation space and the water ball system are in a disconnected state. In this way, the water balloon can be controlled by compressing the urinary catheterization device, and the traditional operation method using multiple syringes is avoided to conduct fluid in the water balloon, so as to facilitate the insertion and removal of the urinary catheter. Procedures to improve their operating efficiency.

Preferably, the difference in cross-sectional area between the telescopic sections is used to make the telescopic sections When compressed, they are socketed sequentially. Therefore, when the medical staff conducts the fluid into the water balloon, it only needs to compress the telescopic parts, which simplifies the operation difficulty of this operation process. When the urethral catheterization device is compressed, the telescoping parts are sleeved and cover the injection port and part of the urethral catheter, which can increase the connection between the urethral catheterization device and the urethral catheter. Stability.

In addition, the urinary catheter infusion device further includes a closed convex piece, which is arranged on the inner side of the bottom of the body to be relatively fixed to the threaded joint, thereby preventing fluid from overflowing or returning to the injection port.

Preferably, the shape of one end of the closed convex member is a tapered shape, and the cross-sectional area of the bottom of the closed convex member is larger than the cross-sectional area of the injection port. Therefore, when the closed convex piece is clamped to the threaded joint, it can be more firmly placed therein and can be more accurately clamped to the threaded joint.

In addition, the urinary catheter infusion device is provided with three such telescopic portions, and the cross-sectional areas of the telescopic portions gradually increase from the threaded joint to the bottom of the body in order.

The body 10 has an accommodation space 101 and a plurality of telescopic portions 102, and the threaded joint 11 is connected to the body 10 and communicates with the accommodation space 101. Wherein, when the threaded joint 11 is connected and screwed to an injection port 21 of the urinary catheter 2, the accommodation space 101 and the water balloon 20 are in a connected state, and the telescopic portion 102 is compressed to provide Conducting fluid into the water balloon 20; and when the threaded joint 11 is connected and unscrewed to the injection port 21, the accommodation space 101 and the water balloon 20 are in a disconnected state. In this way, by controlling the threaded joint 11, the fluid transfer operation of the water balloon 20 can be started or terminated, and by compressing the telescopic portions 102, the fluid can be transferred into the water balloon 20 and made it expand. ,vice versa. Therefore, the urinary catheterization device 1 can avoid the inconvenience caused by the traditional method of performing the operation with a syringe, and is conducive to the medical staff to place and remove the urinary catheter 2 and thereby improve the in situ placement of the urinary catheter 2 The efficiency of entering and removing the patient's body, and at the same time can reduce a large number of consumables and save the cost of the hospital or clinic.

Next, as shown in the use state diagram (a) in FIG. 2A, the catheter catheter 1 is connected to the injection port 21 of the catheter 2, and the threaded joint 11 and the injection port 21 are controlled. The tight state is capable of conducting fluid in the water balloon 20. In this embodiment, please refer to the three-dimensional structure diagram of FIG. 1. The threaded joint 11 is a double-layer coaxial joint, and the innermost threaded joint 11 is provided for connecting the accommodation space 101 and the water ball 20. The inner side of the threaded joint 11 in the outer layer is provided with a threaded structure for screwing to the injection port 21. Therefore, screwing the threaded joint 11 to the injection port 21 can perform fluid conducting operation on the water balloon 20, otherwise, the fluid in the water balloon 20 can be prevented from overflowing or returning to the accommodating space 101, causing the The water balloon 20 retracts to a flat state, which causes the catheter 2 to slide out of the human body. The other end of the catheter 2 is connected to a urine bag. 22 communicates with the urine of the patient. In addition, as shown in FIG. 2B, by compressing the telescopic portions 102, the fluid in the accommodating space 101 can be transmitted to the water balloon 20, so that the water balloon 20 is in an expanded state, so as to facilitate the guide The urinary tube 2 is left in the patient's body, and then the threaded joint 11 can be unscrewed to make the accommodation space 101 and the water balloon 20 in an unconnected state to prevent the fluid that has been conducted into the water balloon 20 from flowing backward. In addition, the urethral catheterization device 1 is still connected to the injection port 21 and is removed together with the urinary catheter 2 until the removal operation of the urinary catheter 2 is performed, thus reducing the traditional use of multiple needles. Waste of barrel operation, and can avoid possible pollution during operation.

Preferably, the difference in cross-sectional area between the telescopic sections 102 is used so that when the telescopic sections 102 are compressed, they are socketed in sequence. In this embodiment, the cross sections of the telescopic sections 102 are circular. The telescopic portions 102 can be compressed and telescoped in sequence like telescopic cups, avoiding the inconvenience of transferring fluid into the water balloon 20 using the traditional syringe injection method, especially when the medical staff can only control with one hand As a result, it can reduce the difficulty of its operation procedures. Therefore, when medical personnel conduct fluid into the water polo 20, they can compress the outermost telescopic portion 102 with one hand, so that the telescopic portions 102 are sequentially socketed, and then the fluid is guided to the water polo. Within 20.

Among them, as shown in FIG. 3, when the telescopic portions 102 are completely compressed, the telescopic portions 102 are sequentially socketed, and the telescopic portion 102 at the bottom end is socketed to the injection port 21 and a part of the The urinary catheter 2 allows the urinary catheterization device 1 to stay on the urinary catheter 2. In other words, from the body 10 to the threaded joint 11, the telescopic portions 102 are sequentially connected to another telescopic portion 102, and so on, so that the telescopic portions 102 are completely compressed, and the bottommost The telescopic portion 102 is sleeved and covers the threaded joint 11 and a part of the urinary catheter 2. Or in another embodiment, the threaded joint 11 is disposed in the topmost telescopic portion 102, that is, the topmost telescopic portion 102 is covered outside the threaded joint 11. So in this threaded joint 11 After being screwed to the injection port 21, the topmost telescopic portion 102 will be fixed to the injection port 21 first, and then after the urinary catheter delivery device 1 is pushed, the other telescopic portions 102 will be sequentially Socket and cover it. In this way, when the telescopic portions 102 are completely compressed, the urinary catheter delivery device 1 is cylindrical and is sleeved on the injection port 21, and at the same time, the fluid in the accommodation space 101 is completely transferred to The water balloon 20 is in an inflated state to prevent the catheter 2 from sliding out of the bladder. Therefore, when a fluid is introduced into the water balloon 20 and the telescopic portions 102 are compressed, the urinary catheter delivery device 1 is firmly connected to the injection port 21 and passes through the socket design of the telescopic portions 102 It can be connected to the urinary catheter 2 in a small volume state, and does not need to be removed and discarded, as in a conventional syringe, but can be connected and left on the urinary catheter 2 without causing patient trouble.

In addition, in order to more reliably prevent the phenomenon of fluid backflow, in this embodiment, the urinary catheter delivery device 1 further includes a closed convex piece 12 which is arranged on the inner side of the bottom of the main body 10 for relative fixing. At the threaded joint 11, fluid overflow or backflow to the injection port 21 is prevented. Please refer to the compression state diagram in FIG. 3 again. When the closed convex piece 12 is clamped on the threaded joint 11, the accommodation space 101 and the urinary catheter 2 are in a disconnected state, which can avoid the loss. The fluid guided to the water balloon 20 is returned to the accommodating space 101 so that the water balloon 20 maintains an expanded state. In this way, when performing the insertion operation of the urinary catheter 2 with one hand, the telescopic portions 102 are compressed to transmit fluid to the water balloon 20, and then the outermost telescopic portion 102 is successively pushed to make the closed convex The piece 12 is clamped to the threaded joint 11 to complete the operation procedure of fluid conduction. Therefore, the locking state of the receiving space 101 and the water ball 20 can be controlled by the closed convex member 12 being locked or removed from the threaded joint 11.

Preferably, in another implementation aspect of this embodiment, the shape of one end of the closed convex member 12 is a pointed cone shape, as shown in FIG. 4, and the cross-sectional area of the bottom of the closed convex member 12 is large. The cross-sectional area of the injection port 21. Among them, since the current urinary catheter 2 is a soft plastic material, such as latex, silicone, or a plastic material coated with a special material, it is convenient to be placed in the human body through its soft texture and elasticity. Therefore, when the closed convex piece 12 with a larger cross-sectional area is fixed to the threaded joint 11, the injection port 21 and the closed convex piece 12 can be brought into a more closed state. In addition, by the tapered design of the closed convex member 12, the screw joint 11 can be more accurately clamped, and it is easier to control.

Furthermore, because the current catheterization operation of the catheter 2 generally requires the delivery of 8 to 10 milliliters of pure water in the water balloon 20, and the actual volume of fluid is determined according to different patient conditions, the catheterization The device 1 can also control the total amount of fluid during the conduction through the volume difference of the telescopic portions 102. Preferably, the urethral catheterization device 1 is provided with three such telescopic portions 102, and the cross-sectional areas of the telescopic portions 102 are gradually increased from the threaded joint 11 to the bottom of the body 10 in order. By providing three such telescoping sections 102, the volume of the fluid that they conduct can be controlled through the compression state of the telescoping sections 102. For example, when the telescoping sections 102 are fully compressed, they can conduct 10 ml of fluid. The fluid enters the water balloon 20. In this way, in addition to containing a sufficient fluid volume, the urethral catheterization device 1 can further utilize the socket design of the telescopic portions 102 to control the amount of fluid it conducts, and can be applied to a variety of conditions. Patients, and have a better control feel and total volume presentation.

In addition, the urinary catheterization device 1 further includes a pulling member 13, which is disposed on the bottom of the body 10. When the removal operation of the urinary catheter 2 is performed, the pulling member 13 is pulled to stretch the compressed and retracted portions 102, so that the retracted portions 102 are restored to the original state, and the water ball 20 is simultaneously The medium fluid is conducted into the accommodation space 101. In this embodiment, the pulling member 13 has a ring-shaped structure for fingers to pull, thereby facilitating one-handed control. With this, The system can quickly recover the fluid in the water balloon 20 and return the water balloon 20 to the original state, so as to facilitate the removal operation of the urinary catheter 2.

Preferably, the pulling member 13 is disposed at a non-center position on the bottom of the body 10. Therefore, it is avoided to apply pressure on the pulling member 13 when compressing the telescopic portions 102, which not only causes discomfort with one-handed operation, but also causes the telescopic portions 102 to be unable to be smoothly connected in order. Thereby, the stability of the urinary catheterization device 1 can be improved, and the convenience of use can be improved.

In addition, the urinary catheterization device 1 further includes a membrane 14 which is arranged in the threaded joint 11 to keep the accommodating space 101 in a sterile state. This can ensure that the ureteral catheterization device 1 is sterile when the urinary catheter 2 is inserted, and can prevent patients from being infected when the urinary catheter 2 is inserted. When the threaded joint 11 is connected to the injection port 21, the film 14 will be ruptured due to the effect of the screwing operation, so that the containing space 101 is connected to the water balloon 20, so as to facilitate subsequent fluid conducting operations.

In summary, the urinary catheter infusion device 1 according to the present invention is connected to the injection port 21 of the urinary catheter 2 by the threaded joint 11 to provide the water balloon 20 of the urinary catheter 2. The fluid is transferred to facilitate the insertion and removal of the catheter 2. Among them, the expansion and contraction sections 102 are used to conduct fluid to the water balloon 20 for compression, so that the water balloon 20 is in an expanded state, and the design of the different cross-sectional areas is used to enable the expansion and contraction sections 102 to be sequentially It is sleeved on the injection port 20 and is firmly connected to the urinary catheter 2 with a minimum volume. In addition, the closed convex piece 12 can be relatively fixed to the threaded joint 11 to prevent the conducted fluid from flowing back into the accommodation space 101. When the removal operation of the urinary catheter 2 is performed, the pulling member 13 can be used to smoothly conduct fluid back to the urinary catheter delivery device 1. In this way, using the urinary catheterization device 1 can avoid the use of a traditional syringe for fluid delivery of the water balloon 20, which not only reduces the consumption of the syringe, but also more convenient. Controlled by medical personnel to improve the operation efficiency of inserting and removing the urinary catheter 2.
