Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a disposable temperature-measuring urinary catheter. Background Technology

[0002] A urinary catheter is a medical device primarily used for patients who cannot urinate independently, such as those recovering from surgery, the elderly, or those suffering from urinary difficulties. Disposable temperature-measuring urinary catheters are one type of urinary catheter.

[0003] In related technologies, a disposable temperature-measuring urinary catheter includes a catheter, a balloon, a temperature sensor, and a data plug. The balloon is located at one end of the catheter, and the catheter has an injection chamber that communicates with the balloon. The temperature sensor is located at the other end of the catheter, and the data plug is electrically connected to the temperature sensor.

[0004] During use, the catheter is inserted into the patient's urethra, and the balloon is inserted into the patient's bladder. Water is injected into the balloon through the injection chamber, causing the balloon to expand and become fixed in the patient's bladder, sealing the urethral opening to achieve urinary catheterization. The body temperature sensor detects the temperature of the urine to monitor the patient's body temperature. At the same time, the data plug connects to a monitor, which can monitor the patient's body temperature in real time.

[0005] However, in practical applications, some body temperature sensors may malfunction after use, requiring reintubation of the patient, causing pain and resulting in a poor user experience. Therefore, improvements are needed. Utility Model Content

[0006] To facilitate the replacement of malfunctioning temperature sensors and reduce patient discomfort, this application provides a disposable temperature-measuring urinary catheter.

[0007] The disposable temperature-measuring urinary catheter provided in this application adopts the following technical solution:

[0008] A disposable temperature-measuring urinary catheter includes a catheter, a connector, a temperature sensor, and a data plug. The connector includes an outlet tube and an installation tube. The outlet tube is located at one end of the catheter and is connected to the catheter. The installation tube is located on the side of the outlet tube near one end of the catheter and is connected to the outlet tube. The temperature sensor is located at one end of the data plug, and the data plug is detachably connected to the installation tube, so that the temperature sensor is located in the installation tube and extends into the outlet tube.

[0009] By adopting the above technical solution, in practical applications, urine flows from the catheter to the urinary catheter for catheterization. The body temperature sensor inserted into the urinary catheter can detect the patient's body temperature through the urine in the urinary catheter. Since the data plug is detachably connected to the installation tube and the body temperature sensor is located at one end of the data plug, when the body temperature sensor malfunctions, it is only necessary to remove the data plug and replace it with a data plug with a new body temperature sensor installed. There is no need to re-insert the catheter into the patient, which can effectively reduce the patient's pain.

[0010] Preferably, the data plug is inserted into the mounting tube.

[0011] By adopting the above technical solution, and by setting the data plug to be inserted into the installation tube, the data plug can be detached, making the operation simple and convenient.

[0012] Preferably, a sealing rubber sleeve is fitted on the end of the data plug near the body temperature sensor, and the sealing rubber sleeve is pressed between the mounting tube and the data plug.

[0013] By adopting the above technical solution and setting a sealing rubber sleeve, the stability of the data plug being inserted into the mounting tube can be improved, and the sealing between the data plug and the mounting tube can also be guaranteed.

[0014] Preferably, the connector further includes a fastening ring, and the end of the mounting tube away from the urinary tube has a plurality of deformation grooves spaced apart along its circumference, and the fastening ring is threadedly connected to the end of the mounting tube away from the urinary tube.

[0015] By adopting the above technical solution and setting a fastening ring, during the process of inserting the data plug into the installation tube, under the action of multiple deformation grooves, the end of the installation tube away from the urinary tube spreads out in all directions to facilitate the insertion of the data plug. Furthermore, by rotating the fastening ring, the fastening ring is threadedly connected to the end of the installation tube away from the urinary tube to clamp the data plug, thereby improving the stability of the data plug installation.

[0016] Preferably, the end of the installation tube away from the urinary tube is provided with a plurality of limiting blocks at intervals along its circumference, and the fastening ring abuts against the plurality of limiting blocks.

[0017] By adopting the above technical solution, multiple limiting rings are set, and the fastening ring abuts against multiple limiting blocks to prevent the fastening ring from detaching from the installation pipe.

[0018] Preferably, the data plug has a positioning ring along its circumference, and the positioning ring abuts against the plurality of limiting blocks.

[0019] By adopting the above technical solution, and by setting a positioning ring that abuts against multiple limit blocks, the data plug insertion position can be positioned, thereby enabling the positioning and installation of the body temperature sensor.

[0020] Preferably, the urinary catheter is widened at the end furthest from the duct.

[0021] By adopting the above technical solution, the urinary catheter is widened at the end away from the duct to facilitate the discharge of urine.

[0022] Preferably, the connector further includes a water injection tube, the end of the catheter away from the urinary tube is provided with a balloon, and the end of the catheter near the urinary tube is provided with a water injection cavity communicating with the balloon along its own length direction. The water injection tube is located on the side of the urinary tube near the end of the catheter and is connected to the water injection cavity.

[0023] By adopting the above technical solution and setting up a water injection pipe, it is possible to inject water into the balloon, thereby facilitating the installation and use of the catheter.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. In practical applications, urine flows from the catheter to the urinary catheter for catheterization. The temperature sensor inserted into the urinary catheter can detect the patient's body temperature through the urine in the urinary catheter. Since the data plug is detachably connected to the installation tube and the temperature sensor is located at one end of the data plug, when the temperature sensor malfunctions, it is only necessary to remove the data plug and replace it with a data plug with a new temperature sensor installed. There is no need to re-insert the catheter into the patient, which can effectively reduce the patient's pain.

[0026] 2. By setting a fastening ring, during the process of inserting the data plug into the installation tube, under the action of multiple deformation grooves, the end of the installation tube away from the urine outlet tube spreads out in all directions to facilitate the insertion of the data plug. Furthermore, by rotating the fastening ring, the fastening ring is threadedly connected to the end of the installation tube away from the urine outlet tube to clamp the data plug, thereby improving the stability of the data plug installation.

[0027] 3. By setting a positioning ring that abuts against multiple limit blocks, the data plug insertion position is positioned, thereby enabling the positioning and installation of the body temperature sensor. Attached Figure Description

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] This application discloses a disposable temperature-measuring urinary catheter.

[0033] Reference Figure 1 and Figure 2 The disposable temperature-measuring urinary catheter includes a catheter 1, a connector 2, a body temperature sensor 3, and a data plug 4. One end of the catheter 1 is open, and the other end has multiple through holes 11 that communicate with the inside of the catheter 1.

[0034] The connector 2 includes a urinary catheter 21 and an installation tube 22. The urinary catheter 21 is sealed and fitted and fixed to the open end of the catheter 1, so that the urinary catheter 21 is connected to the catheter 1. The installation tube 22 is inclined and one end of the installation tube 22 is fixedly connected to the side of the urinary catheter 21 near the end of the catheter 1, and the installation tube 22 is connected to the urinary catheter 21.

[0035] One end of the temperature sensor 3 is fixedly connected to one end of the data plug 4 to establish an electrical connection between the temperature sensor 3 and the data plug 4. Simultaneously, the data plug 4 is detachably connected to the mounting tube 22, allowing the temperature sensor 3 to be located within the mounting tube 22 and extend into the urinary catheter 21 for temperature detection of the urine in the urinary catheter 21. The other end of the data plug 4 is plugged into a monitoring instrument (not shown in the figure) to power the temperature sensor 3. The data plug 4 transmits the detection signal from the temperature sensor 3 to the monitoring instrument.

[0036] In practical applications, catheter 1 is inserted into the patient's urethra. The patient's urine enters catheter 1 through multiple through holes 11 and flows from catheter 1 to urinary catheter 21 for catheterization. In this embodiment, urinary catheter 21 is widened at the end away from catheter 1 to facilitate urine discharge. The body temperature sensor 3, which extends into urinary catheter 21, can detect the patient's body temperature through the urine in urinary catheter 21. The detection signal of body temperature sensor 3 is transmitted to the monitoring instrument through a data connector for display, so as to understand the patient's body temperature in real time.

[0037] Since the data plug 4 is detachably connected to the mounting tube 22 and the body temperature sensor 3 is located at one end of the data plug 4, when the body temperature sensor 3 malfunctions, it is only necessary to remove the data plug 4 and replace it with a new data plug 4 equipped with a new body temperature sensor 3, without having to re-insert the tube into the patient, thereby effectively reducing the patient's pain and improving the patient's user experience.

[0038] In some embodiments, the data plug 4 is inserted into the mounting tube 22 to achieve a detachable connection of the data plug 4. The operation is simple and convenient, thereby facilitating the installation and removal of the data plug 4, and thus facilitating the replacement of the faulty body temperature sensor 3.

[0039] Reference Figure 2 In some embodiments, a sealing rubber sleeve 41 is provided on the end of the data plug 4 near the body temperature sensor 3. When the data plug 4 is inserted into the mounting tube 22, the sealing rubber sleeve 41 is pressed between the mounting tube 22 and the data plug 4. Since the sealing rubber sleeve 41 has a certain elasticity, the data plug 4 is inserted into the mounting tube 22 more stably, thereby improving the stability of the data plug 4 installation and ensuring the sealing between the data plug 4 and the mounting tube 22, so as to avoid urine from flowing out between the data plug 4 and the mounting tube 22 as much as possible.

[0040] In some embodiments, the connector 2 further includes a fastening ring 23. Multiple deformation grooves 221 are evenly spaced along the circumference of the end of the mounting tube 22 away from the urinary tube 21. The deformation grooves 221 are arranged along the length of the mounting tube 22. The fastening ring 23 is threadedly connected to the end of the mounting tube 22 away from the urinary tube 21, and the length of the threaded section of the mounting tube 22 is the same as the length of the deformation grooves 221. When the data plug 4 is inserted into the mounting tube 22, the end of the mounting tube 22 away from the urinary tube 21 spreads outwards under the action of the multiple deformation grooves 221 to facilitate the insertion of the data plug 4. Then, by rotating the fastening ring 23, the fastening ring 23 is threadedly connected to the end of the mounting tube 22 away from the urinary tube 21, thereby clamping the data plug 4 and improving the stability of the data plug 4 installation.

[0041] In some embodiments, the end of the installation tube 22 away from the urinary tube 21 has a plurality of limiting blocks 222 protruding out. The plurality of limiting blocks 222 are evenly spaced along the circumference of the installation tube 22 and are adapted to the plurality of deformation grooves 221. The fastening ring 23 abuts against one side of the plurality of limiting blocks 222 to restrict the fastening ring 23 from detaching from the installation tube 22 and to avoid the fastening ring 23 from being lost as much as possible.

[0042] In some embodiments, the data plug 4 has a positioning ring 42 protruding outwards along its circumference. When the data plug 4 is inserted into the mounting tube 22, the positioning ring 42 abuts against the side of the plurality of limiting blocks 222 away from the fastening ring 23 to position the insertion position of the data plug 4, thereby achieving the positioning and installation of the body temperature sensor 3.

[0043] Reference Figure 1 and Figure 2 In some embodiments, the end of the catheter 1 furthest from the urinary catheter 21 is provided with a balloon 5, and the end of the catheter 1 near the urinary catheter 21 has an injection chamber 12. The injection chamber 12 is arranged along the length of the catheter 1 and communicates with the balloon 5. Meanwhile, the connector 2 also includes an injection tube 24, which is fixedly connected to the side of the urinary catheter 21 near the end of the catheter 1 and communicates with the injection chamber 12. When the catheter 1 is inserted into the patient's urethra, the balloon 5 enters the patient's bladder, and water is injected into the injection tube 24. The water flows into the balloon 5 through the injection chamber 12, causing the balloon 5 to inflate and become fixed in the patient's bladder, sealing the urethral opening. The injection tube 24 facilitates connection to an injection device, thus facilitating the injection of water into the balloon 5 and simplifying the installation and use of the catheter 1.

[0044] The implementation principle of this embodiment is as follows: In practical application, the catheter 1 is inserted into the patient's urethra, and the patient's urine enters the catheter 1 through multiple through holes 11 and flows from the catheter 1 to the urinary catheter 21 for urination. In this embodiment, the urinary catheter 21 is widened at the end away from the catheter 1 to facilitate the discharge of urine. The body temperature sensor 3 inserted into the urinary catheter 21 can detect the patient's body temperature through the urine in the urinary catheter 21. The detection signal of the body temperature sensor 3 is transmitted to the monitoring instrument through the data connector for display, so as to understand the patient's body temperature in real time.

[0045] Since the data plug 4 is detachably connected to the mounting tube 22 and the body temperature sensor 3 is located at one end of the data plug 4, when the body temperature sensor 3 malfunctions, it is only necessary to remove the data plug 4 and replace it with a new data plug 4 equipped with a new body temperature sensor 3, without having to re-insert the tube into the patient, thereby effectively reducing the patient's pain and improving the patient's user experience.

[0046] When the data plug 4 is inserted into the mounting tube 22, the end of the mounting tube 22 away from the urinary tube 21 is spread out in all directions under the action of multiple deformation grooves 221 to facilitate the insertion of the data plug 4. Then, by rotating the fastening ring 23, the fastening ring 23 is threadedly connected to the end of the mounting tube 22 away from the urinary tube 21 to clamp the data plug 4, thereby improving the stability of the data plug 4 installation.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
