Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically a nasopharyngeal temperature monitoring device. Background Technology

[0002] Body temperature is a vital sign during patient surgery and postoperative monitoring, and accurate temperature monitoring provides crucial information for surgeons and anesthesiologists to assess and manage patients. For example, in clinical anesthesia monitoring, core body temperature can be monitored using temperature probes placed in the esophagus (reflecting heart and blood temperature), nasopharynx and cochlea (reflecting brain temperature), and bladder and rectum (reflecting visceral temperature). Common nasopharyngeal temperature probes and their usage methods can be found in patent document CN221654274U. This document discloses a nasopharyngeal temperature monitoring device, comprising a flexible lead wire and a temperature sensing probe. One end of the flexible lead wire has a lead wire interface, and the temperature sensing probe is fixed to the other end of the flexible lead wire to extend into the patient's nasopharynx for temperature detection. Because the nasopharyngeal temperature monitoring probe is placed at a certain angle, and because the nasopharynx contains a significant amount of fluid, it may detach from the nasopharynx during use, affecting the accuracy of temperature monitoring.

These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0015] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0016] like Figures 1-4 As shown, in one or more nasopharyngeal temperature monitoring devices of this embodiment, the device includes a flexible catheter 100 with a temperature sensing probe at its front end and a monitoring data interface 110 electrically connected to the temperature sensing probe at its rear end. The device also includes a fixing assembly 200, which includes a sleeve 210 for tightly fitting onto the flexible catheter 100 and two fixing straps 220 connected to the outside of the sleeve 210.

[0017] In this embodiment, the flexible catheter 100 is made of a flexible material (such as silicone or soft plastic), which has a certain degree of flexibility, allowing it to be inserted into the nasal cavity during surgery without damaging the patient's nasal mucosa. One end of the flexible lead 1 is provided with a monitoring data interface 110 for electrical connection to a temperature monitoring device, enabling visualization of the detected temperature of the nasopharynx. The monitoring data interface 110 can be a USB interface, an RS232 interface, or an RS485 interface; any common interface capable of transmitting electrical signals can be used.

[0018] In an optional embodiment, length markers 120 are provided at both the front end and the middle of the outer side of the flexible catheter 100. The first length marker 120 indicates the position of the temperature sensing probe; when the entire length marker 120 is inserted into the nasopharynx, it indicates that the effective detection area of ​​the temperature sensing probe has entered the nasopharynx. The second length marker 120 indicates the installation position of the fixing assembly 200; the sleeve 210 should be located after the second length marker 120. This length marker 120 also defines the insertion depth of the flexible catheter 100 to avoid damage to the nasopharyngeal mucosa due to excessive insertion.

[0019] In an optional embodiment, the temperature sensing probe is a patch-type sensing probe, which can increase the contact area between the temperature sensing probe 2 and the patient's nasopharynx, thereby improving the accuracy of the detection of the patient's nasopharyngeal temperature.

[0020] In an optional embodiment, the fixing assembly 200 further includes a first tightening sleeve 230 and a second tightening sleeve 240; the first tightening sleeve 230 includes a semi-circular arc-shaped first gripper 231 and a U-shaped first connecting frame 232, the two ends of which are fixedly connected to the upper and lower edges of the first gripper 231, respectively; the second tightening sleeve 240 includes a semi-circular arc-shaped second gripper 241 and a U-shaped second connecting frame 242, the two ends of which are fixedly connected to the upper and lower edges of the second gripper 241, respectively. The concave surface of the first gripper 231 faces the concave surface of the second gripper 241. The width of the second connecting frame 242 is greater than the width of the first connecting frame 232. The upper and lower plates of the second connecting frame 242 have first openings 243 for passing through the upper and lower plates of the first connecting frame 232. The sleeve 210 has several second openings 211 for passing through the upper and lower plates of the first connecting frame 232 and the upper and lower plates of the second connecting frame 242. One end of each of the two fixing straps 220 is fixedly connected to the first connecting frame 232 and the second connecting frame 242, respectively.

[0021] Thus, during use, the first grasping flap 231 and the second grasping flap 241 can firmly grasp the flexible catheter by pulling on the fixation straps 220. Moreover, the tighter the two fixation straps 220 are pulled, the less likely the flexible catheter 100 is to slip off. The fixation straps 220 are generally flexible, thin ropes or straps that can be tied to the patient's head or to other equipment connected to the patient's mouth and nose, such as endotracheal tubes or oxygen tubes.

[0022] The fixing component 200 also includes two adhesive tapes 250, one end of which is fixedly connected to the outside of the sleeve 210. The adhesive tapes 250 can be used flexibly according to actual needs. For example, they can be used to stick to the patient's face or endotracheal tube, or they can be stuck between the sleeve 210 and the first fastening kit 230 or the second fastening kit 240 to further increase the firmness of the connection.

[0023] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
