Description

Technical Field

[0001] The utility model relates to the technical field of body cavity temperature sensors, in particular to a disposable body cavity temperature detection sensor. Background Art

[0002] A temperature sensor converts a temperature variable into a standardized, transmittable output signal. Temperature sensors are categorized by their measurement method: contact and non-contact. They are also divided into RTDs and thermocouples based on the sensor material and electronic component characteristics. They are widely used in temperature detection, monitoring, display, temperature control, and overheat protection.

[0003] From the perspective of medical quality and safety management, intraoperative temperature monitoring is a fundamental and crucial vital sign monitoring program. Surgical patients are subject to significant temperature fluctuations due to multiple factors, including the operating room environment, anesthesia, and infusions. Hypothermia is particularly prevalent in patients undergoing major surgeries, the elderly, and children. Hypothermia can easily lead to complications such as chills, arrhythmias, cardiovascular accidents, coagulopathy, and immunosuppression, increasing perioperative risks. Therefore, continuous temperature monitoring is often used during clinical surgery to ensure intraoperative warmth.

[0004] Existing technologies often use electronic thermometers and infrared thermometers to monitor body surface temperature. However, for surgical patients, these temperature monitors are easily affected by ambient temperature (operating rooms are typically set at 22-25°C), resulting in inaccurate temperature measurements and inability to achieve continuous monitoring. Therefore, during clinical surgery, surface temperature monitoring cannot accurately reflect changes in the patient's core temperature. Utility Model Content

[0005] The purpose of the utility model is to provide a disposable body cavity temperature detection sensor, which is used to solve the problem that the body surface temperature detection sensor used in the prior art cannot accurately reflect the patient's actual body temperature changes.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A disposable body cavity temperature detection sensor includes an output end, a PVC sleeve and a temperature sensing end. The output end and the temperature sensing end are respectively arranged at the two ends of the PVC sleeve. A connecting wire is wrapped inside the PVC sleeve. One end of the connecting wire is electrically connected to the temperature sensing end, and the other end is fixedly connected to an electrode terminal. The electrode terminal is inserted and connected to the output end.

[0008] As a further solution of the present invention: the temperature sensing end includes a thermistor chip, a metal pin and a sealing glass seal layer, one end of the metal pin is welded to each side of the thermistor chip, and the thermistor chip and the metal pin are wrapped and fixed by the sealing glass seal layer, the other end of the metal pin extends outward from the sealing glass seal layer, and the outwardly extending end of the metal pin is welded to one end of the connecting wire.

[0009] As a further solution of the present invention: the sealing glass layer is in a hemispherical structure.

[0010] As a further solution of the present invention: both ends of the output end are respectively provided with an integrated plug-in block and a socket block, the terminal plug-in hole provided on the plug-in block is used to plug and connect the electrode terminal, and the socket block is provided with a through hole to prevent the electrode terminal from entering.

[0011] As a further solution of the present invention: an elastic limiting block is provided on the side wall of the electrode terminal, and a slot adapted for the elastic limiting block is opened on the hole wall of the terminal insertion hole.

[0012] As a further solution of the present invention: a groove is provided on the side wall of the plug-in block.

[0013] As a further solution of the present invention: the diameter of the PVC sleeve is 2.2 mm and the length ranges from 88 to 92 cm.

[0014] Beneficial effects of the utility model:

[0015] (1) The present invention facilitates the passage of the temperature sensing end from the human oral cavity into the human body cavity. The PVC sleeve pulls the temperature sensing end until the temperature sensing end reaches the position for detecting the temperature inside the body cavity. The temperature inside the body cavity can be accurately and quickly detected and output to other devices for digital display, thus solving the problem in the prior art that the surface temperature monitoring sensor cannot accurately reflect the patient's actual body temperature changes.

[0016] (2) The PVC sleeve is soft and has a diameter of 2.2 mm, making it easy to enter the human body cavity from the human mouth. When the tail end of the PVC sleeve pulls the temperature sensing end, the temperature sensing end has a hemispherical structure so that the temperature sensing end will not scratch the mucosa of the human body cavity when it contacts it;

[0017] (3) By wrapping a connecting wire in a PVC sleeve, the metal pins on both sides of the temperature sensing end are electrically connected to the connecting wires respectively, and the two connecting wires are arranged in parallel in the PVC sleeve, thereby reducing the diameter of the PVC sleeve to facilitate pulling the temperature sensing end into the body temperature detection position in the body cavity.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0026] See also Figures 1 to 4 As shown, the utility model is a disposable body cavity temperature detection sensor, including an output end 10, a PVC sleeve 20 and a temperature sensing end 30. The output end 10 and the temperature sensing end 30 are respectively arranged at the two ends of the PVC sleeve 20. A connecting wire 40 is wrapped inside the PVC sleeve 20. One end of the connecting wire 40 is electrically connected to the temperature sensing end 30, and the other end is fixedly connected to the electrode terminal 50. The electrode terminal 50 is inserted and connected to the output end 10.

[0027] During use of the disposable body cavity temperature detection sensor of the present application, it is convenient to enter the human body cavity from the human mouth through the temperature sensing end 30. The PVC sleeve 20 pulls the temperature sensing end 30 until the temperature sensing end 30 reaches the position for detecting the temperature inside the body cavity. The temperature inside the body cavity can be accurately and quickly detected. The detected temperature signal is converted into an electrical signal through the temperature sensing end 30, and the detection electrical signal is transmitted to the electrode terminal 50 by the connecting line 40. The electrode terminal 50 outputs the electrical signal through the output end 10, so that the acquired temperature signal data is converted into a standardized output signal and output to other devices for digital display, thereby solving the problem that the surface temperature monitoring sensor used in the prior art cannot accurately reflect the patient's actual body temperature changes.

[0028] In this specific embodiment, Figure 4 As shown, the temperature sensing end 30 includes a thermistor chip 300, a metal pin 301, and a sealing glass layer 302. One end of the metal pin 301 is welded to each side of the thermistor chip 300. The thermistor chip 300 and the metal pin 301 are wrapped and fixed by the sealing glass layer 302. The other end of the metal pin 301 extends outward from the sealing glass layer 302. The outwardly extending end of the metal pin 301 is welded to one end of the connecting wire 40. During the installation of the temperature sensing end 30, the thermistor chip 300 and the metal pin 301 are wrapped and fixed by the sealing glass layer 302. The sealing glass layer 302 provides insulation and protection for the metal pin 301. The sealing glass layer 302 has good thermal conductivity, allowing the thermistor chip 300 inside to quickly sense changes in temperature parameters within the body cavity, thereby accurately and quickly detecting the body cavity temperature.

[0029] In this specific embodiment, Figure 4 As shown, the sealing glass sealing layer 302 is a hemispherical structure, so that the hemispherical sealing glass sealing layer 302 is fixed to one end of the PVC sleeve 20, thereby facilitating smooth entry into the human body cavity and will not cause scratches to the mucous membrane of the human body cavity when it contacts the mucous membrane.

[0030] In this specific embodiment, Figure 3 As shown, both ends of the output end 10 are respectively provided with an integrated plug-in block 100 and a socket block 101. The terminal plug-in hole 102 provided on the plug-in block 100 is used to plug in the connecting electrode terminal 50, and the socket block 101 is provided with a through hole to avoid the electrode terminal 50 from entering. During the use of the output end 10, after the connecting wire 40 and the electrode terminal 50 are fixedly connected, it is convenient to completely plug and install the electrode terminal 50 from the side of the socket block 101 to the plug-in block 100, which is easy to operate.

[0031] In this specific embodiment, Figure 2 and Figure 3As shown, an elastic limit block 500 is provided on the side wall of the electrode terminal 50, and a card slot for matching the elastic limit block 500 is opened on the hole wall of the terminal plug-in hole 102. During the plug-in installation process of the electrode terminal 50, the elastic limit block 500 abuts and closes against the hole wall of the terminal plug-in hole 102. When plugged into the installation position, the elastic limit block 500 reaches the card slot position opened on the hole wall of the terminal plug-in hole 102, thereby being elastically fixed to ensure stable plug-in installation between the electrode terminal 50 and the output end 10.

[0032] In this specific embodiment, Figure 2 As shown, a groove 103 is provided on the side wall of the plug-in block 100. The groove 103 is provided for quick plug-in and plug-out connection of the output device, which is easy to operate.

[0033] In this specific embodiment, Figure 1 As shown, the diameter of the PVC sleeve 20 is 2.2 mm and the length ranges from 88 to 92 cm, so that the PVC sleeve 20 can pull the temperature sensing end 30 from the human mouth into the human body cavity.

[0034] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
