Technical Field
[0001] This utility model relates to the field of esophageal temperature measurement technology, and more specifically to an esophageal temperature measurement indwelling tube connector. Background Technology
[0002] In clinical medicine, body temperature monitoring is one of the important indicators for assessing patients' vital signs. For patients undergoing surgery, anesthesia, or intensive care, accurate and real-time core body temperature monitoring is particularly crucial. Esophageal temperature measurement is widely used because it can accurately reflect core body temperature.
[0003] Esophageal temperature measurement is usually performed by inserting an indwelling tube with a temperature sensor into the esophagus through the patient's nose or mouth. The outer end of the indwelling tube is connected to the temperature measuring instrument through a connector to form a temperature measuring pathway. Traditional connectors often use a simple plug-and-play structure, which is prone to falling off due to changes in the patient's position or external traction, affecting the continuity of monitoring. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an esophageal temperature monitoring indwelling tube connector to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: an esophageal temperature measurement indwelling tube connector, including an indwelling tube, one end of which is provided with a tube head, and a connector body is provided on one side of the tube head. A positioning ring is integrally formed on one side of the tube head, and two slots are formed on the outer circumferential wall of the positioning ring. A positioning groove is formed on one side of the connector body to cooperate with the positioning ring. An annular groove is formed on the outer circumferential wall of the connector body, and the annular groove and the positioning groove have two points of communication. A rotating ring is rotatably connected inside the annular groove. Two locking blocks are integrally formed on the inner circumferential wall of the rotating ring to cooperate with the slots. A temperature sensor is provided at one end of the connector body, and two core grooves for cooperating with the temperature sensor are formed on the other side of the connector body. Two guide cores for cooperating with the core grooves are provided on one side of the tube head.
[0006] As a further embodiment of this utility model, both the positioning ring and the positioning groove are elliptical, and the shape of the positioning groove matches the shape of the positioning ring.
[0007] As a further embodiment of this utility model, a connecting pipe extends outward from one side of the pipe head, and a groove for cooperating with the connecting pipe is provided on one side of the connector body, and the groove fits into the connecting pipe.
[0008] As a further embodiment of this utility model, an annular rubber ring is adhered to the outer circumference of the rotating ring, and the outer circumference of the annular rubber ring is provided with multiple anti-slip protrusions arranged in a ring array on the outer circumference of the annular rubber ring.
[0009] As a further embodiment of this utility model, the output end of the temperature sensor is connected to a wire, and the inside of the connector body is provided with a wire hole for the wire to pass through, the diameter of the wire hole being smaller than the diameter of the core groove.
[0010] As a further embodiment of this invention, the end of the guide core is arc-shaped, and the length of the guide core is adapted to the depth of the core groove.
[0011] As a further embodiment of this invention, the depth of the annular groove is equal to the sum of the thickness of the rotating ring and the thickness of the locking block.
[0012] As a further embodiment of this utility model, an annular damping protrusion is provided on the inner circumference of the annular groove, and an annular damping groove is provided on the outer circumference of the rotating ring to cooperate with the annular damping protrusion. The annular damping protrusion and the annular damping groove are used in conjunction.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model uses the positioning of the elliptical positioning ring and the positioning groove, as well as the locking of the rotating ring and the positioning ring groove to form a secondary lock, which can effectively prevent the connector from loosening or rotating due to changes in the patient's body position or external force during use, ensuring that the indwelling tube and the connector body always maintain a stable connection, and reducing the risk of temperature measurement interruption due to connection failure.
[0015] 2. This utility model enhances the sealing of the joint through the fitting structure of the connecting pipe and the pipe groove, avoiding interference from external airflow, liquid and other factors on the temperature measurement environment, and further improving the accuracy and reliability of temperature monitoring data.
[0016] 3. This utility model uses the annular damping protrusion on the inner wall of the annular groove and the annular damping groove on the outer wall of the rotating ring to provide appropriate damping when the rotating ring rotates, which is convenient for operation and can prevent it from rotating on its own and causing locking failure.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Reference Figures 1-3 This utility model provides an esophageal temperature measurement indwelling tube connector, including an indwelling tube 1, a tube head 2 at one end of the indwelling tube 1, a connector body 3 on one side of the tube head 2, a positioning ring 9 integrally formed on one side of the tube head 2, two slots 10 formed on the outer circumference of the positioning ring 9, a positioning groove 14 formed on one side of the connector body 3 for cooperating with the positioning ring 9, an annular groove 11 formed on the outer circumference of the connector body 3, and the annular groove 11 and the positioning groove 14 having two connections, a rotating ring 12 rotatably connected inside the annular groove 11, two locking blocks 15 integrally formed on the inner circumference of the rotating ring 12 for cooperating with the slots 10, a temperature sensor 8 (model: small PT100 temperature sensor) at one end of the connector body 3, two core grooves 7 for cooperating with the temperature sensor 8 on the other side of the connector body 3, and two guide cores 5 for cooperating with the core grooves 7 on one side of the tube head 2.
[0023] Furthermore, both the positioning ring 9 and the positioning groove 14 are elliptical, and the shape of the positioning groove 14 matches the shape of the positioning ring 9.
[0024] When the positioning ring 9 is fully embedded in the positioning groove 14, the rotating ring 12 rotates in the annular groove 11. The two locking blocks 15 integrally formed on the inner circumference of the rotating ring 12 will enter the locking groove 10 of the positioning ring 9 through the two connecting points of the annular groove 11 and the positioning groove 14 as the rotating ring 12 rotates, thereby locking the pipe head 2 and the connector body 3.
[0025] Furthermore, a connecting pipe 4 extends outward from one side of the pipe head 2, and a pipe groove 6 is provided on one side of the connector body 3 to cooperate with the connecting pipe 4. The pipe groove 6 fits into the connecting pipe 4.
[0026] During installation, the elliptical positioning ring 9 on one side of the pipe head 2 matches the elliptical positioning groove 14 of the connector body 3, and at the same time, the connecting pipe 4 extending outward from the pipe head 2 is inserted into the pipe groove 6 of the connector body 3.
[0027] The fitting structure between the connecting pipe 4 and the groove 6 enhances the joint sealing, avoids interference from external airflow, liquid and other factors on the temperature measurement environment, and further improves the accuracy and reliability of temperature monitoring data.
[0028] Among them, an annular rubber ring 13 is adhered to the outer circumference of the rotating ring 12, and multiple anti-slip protrusions are arranged in a ring array on the outer circumference of the annular rubber ring 13.
[0029] The annular rubber ring 13 on the outer circumference of the rotating ring 12 and its anti-slip protrusions increase the friction between the operator's hand and the rotating ring 12, making it easier to rotate the rotating ring 12 during installation and disassembly, thus improving the ease of operation.
[0030] In this invention, the output end of the temperature sensor 8 is connected to a wire, and the inside of the connector body 3 is provided with a wire hole for the wire to pass through. The diameter of the wire hole is smaller than the diameter of the core groove 7.
[0031] During the temperature measurement phase, the temperature sensor 8 senses the temperature through contact with the guide core 5 and transmits the temperature signal through the wire connected to the output end. The wire passes through the wire hole inside the connector body 3 to realize the real-time transmission of temperature data.
[0032] Furthermore, the end of the guide core 5 is arc-shaped, and the length of the guide core 5 is adapted to the depth of the core groove 7.
[0033] In this invention, the depth of the annular groove 11 is equal to the sum of the thickness of the rotating ring 12 and the thickness of the locking block 15.
[0034] The annular groove 11 has an annular damping protrusion on its inner circumference and an annular damping groove that mates with the annular damping protrusion on its outer circumference. The annular damping protrusion and the annular damping groove are used together.
[0035] The annular damping protrusion on the inner circumference of the annular groove 11 cooperates with the annular damping groove on the outer circumference of the rotating ring 12, so that the rotating ring 12 has appropriate damping when it rotates, which is convenient for operation and can prevent it from rotating on its own and causing locking failure.
[0036] The use of this utility model involves the following steps:
[0037] S1: During installation and connection, the elliptical positioning ring 9 on one side of the pipe head 2 matches the elliptical positioning groove 14 of the connector body 3, and at the same time, the connecting pipe 4 extending outward from the pipe head 2 is inserted into the pipe groove 6 of the connector body 3.
[0038] S2: When the positioning ring 9 is fully embedded in the positioning groove 14, the rotating ring 12 rotates in the annular groove 11. The two locking blocks 15 integrally formed on the inner circumference of the rotating ring 12 will enter the locking groove 10 of the positioning ring 9 through the two connecting points between the annular groove 11 and the positioning groove 14 as the rotating ring 12 rotates, thereby locking the pipe head 2 and the connector body 3.
[0039] S3: During the temperature measurement phase, the temperature sensor 8 senses the temperature through contact with the guide core 5 and transmits the temperature signal through the wire connected to the output end. The wire passes through the wire hole inside the connector body 3 to realize the real-time transmission of temperature data.
[0040] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
