Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a disposable body cavity temperature probe. Background Technology

[0002] In the medical field, continuous and accurate monitoring of a patient's body temperature is crucial. Currently, various types of thermometers are available on the market, such as traditional mercury thermometers and electronic thermometers.

[0003] However, these thermometers have certain limitations in use, such as long measurement time and measurement accuracy being affected by ambient temperature. For patients who need to continuously monitor their body temperature, especially when rectal temperature monitoring is required, the thermometer needs to be inserted into the anus. The insertion process can not only make patients feel uncomfortable, but also easily cause damage to the inner wall of the anus. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a disposable body cavity temperature probe.

[0005] The disposable body cavity temperature probe provided in this application adopts the following technical solution:

[0006] A disposable body cavity temperature probe includes an instrument connector, an insulating sleeve, a signal transmission cable, and a temperature probe. The insulating sleeve has a smooth surface. The instrument connector is installed at one end of the insulating sleeve, and the temperature probe is installed at the other end of the insulating sleeve. A signal transmission cable is connected inside the insulating sleeve, and the two ends of the signal transmission cable are respectively connected to the instrument connector and the temperature probe.

[0007] By adopting the above technical solution, the signal transmission cable is wrapped with a smooth insulating sleeve, which reduces the foreign body sensation when inserted into the anus and other cavities of the human body, improving the patient's comfort during temperature monitoring. At the same time, the insulating material provides protection, preventing the patient from being harmed by electric leakage or other dangers during temperature monitoring. After being inserted into the anus and other cavities of the human body, the temperature probe monitors the changes in body temperature in real time and transmits the data to the instrument connection plug via the signal transmission cable. The instrument connection plug then connects to an external instrument to store or display the temperature changes.

[0008] Optionally, the end of the temperature probe furthest from the instrument connector is a semi-circular arc surface.

[0009] By adopting the above technical solution, the semi-circular surface can fit the inner wall of the patient's anus without any sharp edges or thorns, making the patient more comfortable when inserted into the body, while also reducing the difficulty of insertion and making the insertion smoother.

[0010] Optionally, the diameter of the temperature probe matches the inner diameter of the insulating sleeve, and the temperature probe moves along the inner wall of the insulating sleeve; a switching port is provided at one end of the insulating sleeve near the instrument connection plug; a push-out sleeve is also provided inside the insulating sleeve; the push-out sleeve is connected to the temperature probe, and the push-out sleeve extends out of the switching port.

[0011] By adopting the above technical solution, the temperature probe can be inserted into the insulating sleeve by pulling the push-pull sleeve outside the switching port. The insulating sleeve isolates the excrement from infection. When it is moved to the rectum or other locations where body temperature needs to be monitored, the push-pull sleeve is pushed to push the temperature probe out of the insulating sleeve. This ensures that the temperature probe will not come into contact with the patient's excrement during insertion, thus guaranteeing the accuracy of temperature monitoring data.

[0012] Optionally, a push-pull ring is provided at the switching port; the push-pull ring is connected to the push-moving sleeve.

[0013] By adopting the above technical solution, the push-pull ring can be set around the outer wall of the insulating sleeve. Therefore, regardless of whether the push-pull sleeve outside the switching port is found, the push-pull ring can be touched or grasped, which improves the convenience of use.

[0014] Optionally, the push sleeve is located inside the insulating sleeve, and the push-pull ring is provided with an extension protrusion, which passes through the switching port and connects to the push sleeve.

[0015] By adopting the above technical solution, after the extension protrusion extends into the switching port and connects with the push sleeve, there is no need to push the push sleeve. Only the push-pull ring needs to be pushed to push and pull the push sleeve using the extension protrusion. The push sleeve will not extend out of the switching port, so there will be no leakage.

[0016] Optionally, a limiting ring is provided on the inner wall of the insulating sleeve; the limiting ring is located at the end of the insulating sleeve near the temperature probe.

[0017] By adopting the above technical solution, the limiting ring can limit the distance the temperature probe extends into the insulating sleeve, thus preventing the temperature probe from extending too far into the insulating sleeve and thus making it impossible to smoothly push the temperature probe out of the insulating sleeve opening.

[0018] Optionally, the temperature probe has an anti-drop protrusion at the end near the instrument connector; the anti-drop protrusion contacts the limiting ring.

[0019] By adopting the above technical solution, when the limiting ring is set at the opening of the insulating sleeve, the temperature probe can extend out of the limiting ring. However, the diameter of the anti-fall protrusion is larger than the inner diameter of the limiting ring, so it cannot detach from the opening of the insulating sleeve, thereby preventing the temperature probe from detaching from the insulating sleeve as a whole.

[0020] Optionally, two limiting rings are provided: one is located at the end of the insulating sleeve away from the instrument connection plug, and the other is set at a distance from the length of the temperature probe in the direction of the instrument connection plug.

[0021] By adopting the above technical solution, the insertion and extension lengths of the temperature probe are controlled by using two limiting rings and anti-drop protrusions, avoiding excessive insertion that makes it difficult to push or excessive extension that causes it to detach from the insulating sleeve, thus improving the comfort of use.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The signal transmission cable is wrapped with a smooth insulating sleeve, which reduces the feeling of a foreign body when inserted into the anus and other cavities of the human body, and improves the patient's comfort during temperature monitoring. At the same time, the insulating material provides protection, so that the patient can avoid dangers such as electric leakage during temperature monitoring. After being inserted into the anus and other cavities of the human body, the temperature probe monitors the changes in body temperature in real time and transmits the data to the instrument connection plug through the signal transmission cable. The instrument connection plug connects to external instruments to store or display temperature changes.

[0024] 2. The semi-circular surface can fit the inner wall of the patient's anus without any sharp edges or barbs, making it more comfortable for the patient when inserted into the body, while also reducing the difficulty of insertion and making the insertion smoother.

[0025] 3. By pulling the push-pull sleeve outside the switching port, the temperature probe can be inserted into the insulating sleeve. The insulating sleeve isolates the excrement from infection. When it is moved to the rectum or other locations where body temperature needs to be monitored, the push-pull sleeve is pushed to push the temperature probe out of the insulating sleeve. This prevents the temperature probe from coming into contact with the patient's excrement during insertion, ensuring the accuracy of temperature monitoring data.

[0026] 4. The push-pull ring can be set around the outer wall of the insulating sleeve, so the push-pull ring can be touched or grasped regardless of whether the push-pull sleeve outside the switching port is found, which improves the convenience of use. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3This application will be described in further detail below.

[0037] This application discloses a disposable body cavity temperature probe.

[0038] A disposable body cavity temperature probe is used for patients whose body temperature needs to be continuously measured in cavities such as the rectum and anus. It monitors the body temperature and can provide real-time temperature monitoring data. It is used in conjunction with a multi-parameter monitor with body temperature monitoring function. It is used for one-time use when collecting and transmitting the patient's body temperature signal. This application can be discarded after monitoring to avoid the situation where bacteria adhere to the probe after use and cause infection to other patients.

[0039] refer to Figure 1 As shown, it includes an instrument connection plug 1, an insulating sleeve 2, a signal transmission cable 3, and a temperature probe 4; the insulating sleeve 2 can be a white medical PVC sleeve, referred to simply as insulating sleeve 2. The surface of the insulating sleeve 2 is soft and smooth, allowing it to reach directly into the human body and preventing damage during insertion.

[0040] The instrument connection plug 1 can be inserted into an external instrument, such as a multi-parameter monitor or an external computer or other data monitoring equipment, to provide the transmission of body temperature data. The instrument connection plug 1 is installed at one end of the insulating sleeve 2, and the temperature probe 4 is installed at the other end of the insulating sleeve 2. A signal transmission cable 3 is connected inside the insulating sleeve 2. The signal transmission cable 3 is used to provide the transmission of body temperature signals. The surface of the signal transmission cable 3 is also wrapped with an insulating outer sheath, which is synchronously insulated with the insulating sleeve 2 to further ensure the insulation performance.

[0041] The two ends of the signal transmission cable 3 are connected to the instrument connection plug 1 and the temperature probe 4, respectively, so that the human body temperature data monitored by the temperature probe 4 can be transmitted to the instrument connection plug 1 through the signal transmission cable 3. The instrument connection plug 1 is then connected to an external instrument for data storage or display.

[0042] Among them, temperature probe 4 can be an NTC temperature probe 4, also known as an NTC temperature sensor, which is a thermistor. Temperature probe 4 can be used to monitor the body temperature on the surface of human skin or inside the body. Simultaneously, the body temperature monitoring data is transmitted to an external display device or a multi-parameter monitor via a signal transmission cable to achieve the function of real-time monitoring of changes in human body temperature.

[0043] Specifically, the signal transmission cable is wrapped in a smooth insulating sleeve 2, which reduces the feeling of a foreign object when inserted into the anus and other cavities of the human body, improving the patient's comfort during temperature monitoring. At the same time, the insulating material provides protection, preventing the patient from being harmed by electric leakage or other dangers during temperature monitoring. After being inserted into the anus and other cavities of the human body, the temperature probe 4 monitors the changes in body temperature in real time and transmits the data to the instrument connection plug 1 via the signal transmission cable 3. The instrument connection plug 1 then connects to an external instrument to store or display the temperature changes.

[0044] Furthermore, the end of the temperature probe 4 away from the instrument connection plug 1 is a semi-circular arc surface, that is, the end that is inserted into the patient's body from the anus or other locations is a semi-circular arc surface. The semi-circular arc surface can fit the inner wall of the patient's anus without any sharp edges or thorns, making the patient more comfortable when inserted into the body, while also reducing the difficulty of insertion and making the insertion smoother.

[0045] In some embodiments, reference Figure 2 As shown, the diameter of the temperature probe 4 is matched with the inner diameter of the insulating sleeve 2, that is, the diameter of the temperature probe 4 is less than or equal to the inner diameter of the insulating sleeve 2, so that the temperature probe 4 can move along the inner wall of the insulating sleeve 2, or extend out of the opening of the insulating sleeve 2 or into the opening of the insulating sleeve 2.

[0046] The insulating sleeve 2 has a switching port 21 at one end near the instrument connection plug 1. The insulating sleeve 2 also has a push sleeve 5 inside. The diameter of the push sleeve 5 is smaller than that of the insulating sleeve 2, so it can be located inside the insulating sleeve 2 and move along the inside of the insulating sleeve 2.

[0047] The push-out sleeve 5 is connected to the temperature probe 4, and the push-out sleeve 5 extends out of the switching port 21. The push-out sleeve 5 can be extended out of the insulating sleeve 2 using the switching port 21, so that there is a fulcrum outside the insulating sleeve 2 that can pull the push-out sleeve 5. As the medical staff pulls the push-out sleeve 5, the push-out sleeve 5 moves along the inner wall of the insulating sleeve 2. During the movement, the temperature probe 4 is pulled at the same time, so that the temperature probe 4 can be retracted into the insulating sleeve 2 or extended out of the insulating sleeve 2.

[0048] The insulating sleeve 2 has a chamfered end away from the instrument connection plug 1 to reduce sharp edges and avoid causing injury or discomfort to the patient when inserted into the anus or other cavities of the human body.

[0049] Specifically, when it is necessary to insert the temperature probe 4 into the human anus or other cavities, the insulating sleeve 2 of one end of the temperature probe 4 is inserted into the rectum from the patient's anus, so that one end of the temperature probe 4 will come into contact with the inner wall of the patient's anus. The inner wall of the patient's anus is more or less covered with excrement. Therefore, the temperature probe 4 is easy to come into contact with excrement during insertion, causing excrement to adhere to the surface of the temperature probe 4, which leads to inaccurate temperature monitoring.

[0050] Therefore, before inserting it into the patient's anus, by pulling the push-pull sleeve 5 outside the switching port 21, the push-pull sleeve 5 can drive the temperature probe 4 into the insulating sleeve 2. The insulating sleeve 2 isolates the excrement from infection. When it moves to the rectum or other locations where body temperature needs to be monitored, the push-pull sleeve is pushed, causing the push-pull sleeve to push the temperature probe 4 out of the insulating sleeve 2. This ensures that the temperature probe will not come into contact with the patient's excrement during insertion, thus ensuring the accuracy of temperature monitoring data.

[0051] Further reference Figure 3 As shown, a push-pull ring 6 is provided at the switching port 21. The push-pull ring 6 is connected to the push sleeve 5. The push-pull ring 6 is used to pull or push the push sleeve 5. The push-pull ring 6 can be set around the outer wall of the insulating sleeve 2. Therefore, the push-pull ring 6 can be touched or grasped regardless of whether the push-pull sleeve outside the switching port 21 is found, which improves the convenience of use.

[0052] Furthermore, the push sleeve 5 is located inside the insulating sleeve 2, and the diameter of the switching port 21 is smaller than that of the push sleeve 5, preventing the push sleeve 5 from being pulled out of the switching port 21. The push-pull ring 6 is provided with an extension protrusion 61, which passes through the switching port 21 and connects to the push sleeve 5. The switching port 21 can be in the shape of a straight line, opened along the extension length direction of the insulating sleeve 2, and the number of switching ports 21 can be set to several. The number of extension protrusions 61 is consistent with the number of switching ports 21 and corresponds one-to-one, so that during movement... When the force is more even, the push sleeve 5 is connected to the push sleeve 5 by extending the extension protrusion 61 into the switching port 21. There is no need to push the push sleeve 5. Just push the push-pull ring 6. The push sleeve 5 can be pushed and pulled by the extension protrusion 61. The push sleeve 5 will not extend out of the switching port 21, which ensures that in the event of leakage, the push sleeve 5 will not be affected by extending from the switching port 21. At the same time, the push-pull ring 6 can cover the switching port 21, which can also ensure safety.

[0053] The push-pull ring 6 is made of insulating material and is wider than the switching port 21, so that the push-pull ring 6 can cover the switching port 21, improving safety and preventing leakage.

[0054] In some embodiments, reference Figure 3As shown, the inner wall of the insulating sleeve 2 is provided with a limiting ring 7. The limiting ring 7 is located at the end of the insulating sleeve 2 near the temperature probe 4. The limiting ring 7 can limit the distance that the temperature probe 4 extends into the insulating sleeve 2, so as to avoid the temperature probe 4 extending too far into the insulating sleeve 2, which would prevent the temperature probe 4 from being pushed out of the opening of the insulating sleeve 2 smoothly, or the pushing sleeve 5 may be bent when pushed too far, which would affect the insulating sleeve 2 and make the patient feel uncomfortable.

[0055] Furthermore, the temperature probe 4 is provided with an anti-drop protrusion 41 at one end near the instrument connection plug 1. The anti-drop protrusion 41 contacts the limiting ring 7. When the limiting ring 7 is set at the opening of the insulating sleeve 2, the temperature probe 4 can extend out of the limiting ring 7. However, the diameter of the anti-drop protrusion 41 is larger than the inner diameter of the limiting ring 7, so it cannot detach from the opening of the insulating sleeve 2, thereby preventing the temperature probe 4 from detaching from the insulating sleeve 2 as a whole.

[0056] Furthermore, there are two limiting rings 7. One is located at the end of the insulating sleeve 2 away from the instrument connection plug 1, and the other is set at a distance from the length of the temperature probe 4 in the direction of the instrument connection plug 1. By using the two limiting rings 7 and the anti-drop protrusion 41, the length of the temperature probe 4 inserted and extended is controlled, so as to avoid it being too long to be pushed or too long to be detached from the insulating sleeve 2, thereby improving the comfort of use.

[0057] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
