Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a body temperature detection tube and an intubation device having the same. Background Technology

[0002] In the emergency rescue of critically ill patients, in order to avoid obstruction of the patient's trachea or bronchi and endanger their life, medical staff usually perform "airway opening" by tracheal or bronchial intubation to establish a temporary artificial breathing channel for the patient's trachea or bronchi.

[0003] To monitor the temperature inside a patient's trachea or bronchi, existing catheters are equipped with temperature detection devices to obtain temperature information and provide data support for surgical procedures. However, the current design of these devices leaves air between the device and the trachea or bronchi, making the temperature readings highly susceptible to air temperature fluctuations and resulting in inaccurate measurements. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a body temperature detection tube and an intubation device having the same, which can solve the problem of inaccurate temperature measurement of the inner wall of the trachea or bronchi.

[0005] The solution to the technical problem of this utility model is:

[0006] Firstly, a body temperature detection tube includes:

[0007] catheter;

[0008] A venting tube is hollow to form an airway and has an air inlet. The air inlet is connected to the airway, and the conduit passes through the airway.

[0009] An airbag includes an inner diaphragm and an outer diaphragm. The inner diaphragm is connected to the end of the air tube and is hollow to form an air chamber. The air chamber is connected to the airway. The outer diaphragm covers the outside of the inner diaphragm. The inside of the outer diaphragm and the outside of the inner diaphragm together form a temperature sensing chamber.

[0010] The temperature measuring component includes a temperature sensor and a heat-conducting wire. The heat-conducting wire is disposed inside the temperature sensing cavity. One end of the heat-conducting wire is connected to the temperature measuring end of the temperature sensor. The temperature sensor is used to acquire the temperature information of the heat-conducting wire.

[0011] This invention has at least the following beneficial effects: gas enters the airway through the air inlet, filling the air chamber and causing the inner diaphragm to bulge outward. The heating wire and outer diaphragm bulge outward under the action of the inner diaphragm. The outer diaphragm adheres tightly to the inner wall of the trachea or bronchus and forms a support, enabling the catheter to establish a temporary artificial breathing channel for the patient. The heating wire adheres tightly to the inner wall of the outer diaphragm, allowing heat transfer to the inner wall of the trachea or bronchus. The temperature sensor detects the temperature of the heating wire, achieving temperature measurement of the inner wall of the trachea or bronchus. The temperature measurement process is not affected by air, resulting in more accurate temperature measurement results.

[0012] As a further improvement to the above technical solution, multiple heat-conducting wires are provided, and these multiple heat-conducting wires are evenly distributed within the temperature-sensing cavity. With this arrangement, the temperature-sensing component can perform heat conduction temperature measurement in all directions of the temperature-sensing cavity, thereby improving the accuracy of temperature measurement.

[0013] As a further improvement to the above technical solution, the heat-conducting wire is provided with a multi-segment curved structure, and the multiple segments of the curved structure are connected in sequence. This arrangement can increase the temperature-sensing area of ​​the heat-conducting wire, thereby improving the accuracy of temperature measurement.

[0014] As a further improvement to the above technical solution, the length of the heat-conducting wire along the extension direction of the conduit is greater than the length of the inner diaphragm along the extension direction of the conduit. With this configuration, when the inner diaphragm bulges, the heat-conducting wire can be positioned along the outer wall of the inner diaphragm along the extension direction of the conduit, thereby measuring the temperature of the entire airbag along the extension direction of the conduit and improving the accuracy of temperature measurement.

[0015] As a further improvement to the above technical solution, the heat-conducting wire is provided with a fixed end, which is fixedly connected to the inner wall of the temperature-sensing cavity. The fixed end is the end where the heat-conducting wire is connected to the temperature sensor. Since one end of the heat-conducting wire is fixed to the inner wall of the temperature-sensing cavity, it can prevent the heat-conducting wire from moving or falling off within the temperature-sensing cavity.

[0016] As a further improvement to the above technical solution, the heat-conducting wire has a free end, which is the end of the heat-conducting wire away from the temperature sensor, and the free end is hemispherical. This design can prevent the free end of the heat-conducting wire from puncturing the inner diaphragm, thereby ensuring that the heat-conducting wire remains in close contact with the inner wall of the outer diaphragm during the inflation of the airbag, and improving the accuracy of temperature measurement.

[0017] As a further improvement to the above technical solution, the catheter is one of a bronchial catheter, a tracheal catheter, or a tracheostomy catheter. The appropriate catheter for the procedure is selected to suit intubation procedures at different sites.

[0018] As a further improvement to the above technical solution, the outer wall of the catheter is provided with graduation lines, which are arranged along the extension direction of the catheter. By setting graduation lines, the operator can know the length of the catheter inserted into the patient's body, which facilitates subsequent surgical operations.

[0019] As a further improvement to the above technical solution, the heat-conducting wire is made of a metal material. Being made of a metal material enables excellent heat conduction and provides good ductility, which facilitates the deformation and heat conduction of the heat-conducting wire, thereby improving the accuracy of temperature measurement.

[0020] In a second aspect, there is an intubation device, comprising a monitor and a body temperature detection tube as described in any of the technical solutions in the first aspect, wherein the temperature sensor of the body temperature detection tube is electrically connected to the monitor.

[0021] Because the intubation device is equipped with a specially designed temperature detection tube, it can establish a temporary breathing channel for patients during endotracheal tube intubation, bronchial tube intubation, or tracheotomy. At the same time, the bulging outer diaphragm can contact the inner wall of the patient's trachea or bronchus to form support. The heating wire set in the temperature sensing cavity can be closely attached to the inner wall of the outer diaphragm, and the temperature sensor can obtain the temperature of the heating wire. It can detect the temperature in the human trachea or bronchus in a non-contact manner and transmit the temperature information to the monitor for display, providing data support for the operator.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model 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 limitations on this utility model.

[0031] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0034] In the first aspect, this utility model embodiment proposes a body temperature detection tube that can perform tracheal intubation, bronchial intubation or tracheotomy after the body temperature detection tube is inserted into the patient's body, and can accurately obtain the temperature of the inner wall of the trachea or bronchus, providing parameter support for subsequent diagnosis and treatment.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the body temperature detection tube includes a catheter 100, a ventilation tube 200, an air bag 300, and a temperature measuring component 400. Among them, the catheter 100 is a medical-specific tube used to establish a temporary artificial breathing channel for the patient during intubation surgery.

[0036] The ventilator 200 is hollow to form an airway and has an air inlet that communicates with the airway. The ventilator 200 is located outside the conduit 100, meaning the conduit 100 passes through the airway. The airbag 300 includes an inner diaphragm 310 and an outer diaphragm 320. The inner diaphragm 310 is connected to the end of the ventilator 200 and is hollow to form an air chamber that communicates with the airway. The outer diaphragm 320 covers the outer side of the inner diaphragm 310, and the outer side of the inner diaphragm 310 and the inner side of the outer diaphragm 320 together form a temperature-sensing cavity 330.

[0037] Reference Figure 3 , Figure 4 and Figure 5 The temperature measuring component 400 includes a temperature sensor 410 and a heat-conducting wire 420. The heat-conducting wire 420 is used to conduct heat to the temperature measuring point, and the temperature sensor 410 is used to acquire the temperature information of the heat-conducting wire 420. After acquiring the temperature information of the heat-conducting wire 420, the temperature information is transmitted to the display device for display, so that the operator can know the temperature value of the measuring location. Specifically, the heat-conducting wire 420 is disposed in the temperature sensing cavity 330. One end of the heat-conducting wire 420 is a fixed end, and the other end is a free end. The fixed end of the heat-conducting wire 420 is connected to the temperature measuring end of the temperature sensor 410.

[0038] During use, the operator connects the air inlet to the inflation device, allowing gas to enter the air passage from the air inlet and flow along the air passage to the bulging cavity formed by the inner diaphragm 310. The gas fills the bulging cavity, causing the inner diaphragm 310 to bulge outward. Under the action of the inner diaphragm 310, the heat-conducting wire 420 adheres tightly to the outer diaphragm 320 and deforms with the inner diaphragm 310. Under the action of the inner diaphragm 310 and the heat-conducting wire 420, the outer diaphragm 320 bulges outward and adheres tightly to the temperature measuring point, thus ensuring that the heat-conducting wire 420 adheres tightly to the temperature measuring point. The heat-conducting wire 420 transfers the heat from the temperature measuring point to the temperature sensor 410, allowing the temperature sensor 410 to measure and obtain the temperature value of the temperature measuring point.

[0039] Understandably, in order to make the temperature sensing cavity 330 clearly visible, the distance between the inner diaphragm 310 and the outer diaphragm 320 is relatively large in the attached figure to facilitate understanding of the placement of the heat-conducting wire 420. In reality, the space of the temperature sensing cavity 330 is very small. When the bulging cavity of the inner diaphragm 310 is inflated, the outer diaphragm 320 and the inner diaphragm 310 are in a tight fit.

[0040] The first state is defined as the deflated state of airbag 300, with reference to... Figure 1 and Figure 3 The second state is defined as the airbag inflating to 300mm. Figure 2 and Figure 4 .

[0041] The catheter 100 can be one of a bronchial catheter, tracheal catheter, or tracheostomy catheter. A bronchial catheter is used to establish a temporary artificial breathing channel for a patient at the bronchial level. A tracheal catheter is used to establish a temporary artificial breathing channel for a patient at the trachea level; it can be an orotracheal catheter, a nasotracheal catheter, or a percutaneous tracheal catheter. A tracheostomy catheter is used in tracheotomy to create an artificial airway in the trachea that needs to be cut open, resolving breathing difficulties or asphyxiation in patients.

[0042] In some embodiments, the heat-conducting wire 420 is provided by multiple wires, which are evenly distributed in the temperature sensing cavity 330, enabling heat conduction and temperature measurement in all directions of the temperature sensing cavity 330, thereby improving the accuracy of temperature measurement.

[0043] In this embodiment, four heat-conducting wires 420 are provided, which are distributed on the front, rear, left and right sides of the inner diaphragm 310, and the distribution can perform heat conduction and temperature measurement on the front, rear, left and right sides of the conduit 100.

[0044] In some embodiments, the heat-conducting wire 420 is provided with multiple curved structures 421, and the multiple curved structures 421 of the same heat-conducting wire 420 are connected in sequence. This arrangement can increase the temperature sensing area of ​​the heat-conducting wire 420, thereby improving the accuracy of temperature measurement.

[0045] In some embodiments, the curved structure 421 is positioned near the free end of the heat-conducting wire 420. When the inner diaphragm 310 bulges outward, the position of the curved structure 421 also bulges outward along with the bulging of the inner diaphragm 310, thereby making the curved structure 421 close to the measured position.

[0046] In this embodiment, the length of the heat-conducting wire 420 along the extension direction of the conduit 100 is greater than the length of the inner diaphragm 310 along the extension direction of the conduit 100. With this configuration, when the inner diaphragm 310 bulges, the heat-conducting wire 420 can be positioned along the outer wall of the inner diaphragm 310 along the extension direction of the conduit 100, thereby measuring the temperature of the entire airbag 300 along the extension direction of the conduit 100 and improving the accuracy of temperature measurement.

[0047] In this embodiment, the fixed end of the heat-conducting wire 420 is fixedly connected to the inner wall of the temperature-sensing cavity 330 to ensure that the position of the temperature-measuring end of the temperature sensor 410 is not affected by the deformation of the airbag 300 during inflation or deflation, thereby improving the temperature measurement accuracy of the temperature sensor 410. Moreover, since one end of the heat-conducting wire 420 is fixed to the inner wall of the temperature-sensing cavity 330, it can prevent the heat-conducting wire 420 from moving or falling off within the temperature-sensing cavity 330.

[0048] In this embodiment, the heat-conducting wire 420 is bonded to the inner wall of the temperature-sensing cavity 330 with an adhesive, so that the heat-conducting wire 420 can remain fixed to the airbag 300 whether the airbag 300 is inflated or deflated.

[0049] In some embodiments, the free end of the heat-conducting wire 420 is hemispherical.

[0050] Understandably, when the airbag 300 inflates, the orientation of the free end of the heating wire 420 is affected. The heating wire 420 bulges along the outer wall of the inner diaphragm 310, and the orientation of the free end gradually changes from the direction of extension along the conduit 100 to the direction towards the central axis of the conduit 100. The free end may puncture the inner diaphragm 310. When the inner diaphragm 310 is punctured, although the airway and the temperature sensing cavity 330 are connected, allowing the ventilator 200 to inflate the outer diaphragm 320, the heating wire 420 cannot deform with the inflation of the outer diaphragm 320. Therefore, the heating wire 420 cannot adhere tightly to the inner wall of the outer diaphragm 320 to achieve heat conduction and temperature sensing, resulting in inaccurate temperature measurement.

[0051] Designing the free end of the heat-conducting wire 420 as a hemispherical shape can prevent the free end of the heat-conducting wire 420 from puncturing the inner diaphragm 310, thereby ensuring that the heat-conducting wire 420 remains in close contact with the inner wall of the outer diaphragm 320 during the inflation of the airbag 300, thus improving the accuracy of temperature measurement.

[0052] In addition, designing the free end as a hemispherical shape can also prevent the free end of the heat-conducting wire 420 from puncturing the outer diaphragm 320 when the airbag 300 is in the ventilated state, thereby preventing the heat-conducting wire 420 from piercing the outside of the airbag 300 and injuring the patient.

[0053] In this embodiment, the outer wall of the catheter 100 is provided with graduation lines, which are arranged along the extension direction of the catheter 100. By providing graduation lines, the operator can know the length of the catheter 100 inserted into the patient's body, which facilitates subsequent surgical procedures.

[0054] The heat-conducting wire 420 is made of a metallic material, which provides good thermal conductivity and has good ductility, such as aluminum or silver. In this embodiment, the heat-conducting wire 420 is a tungsten alloy, which has good thermal conductivity and ductility, and is also low in cost.

[0055] On the other hand, this utility model embodiment also proposes an intubation device, including a monitor and a body temperature detection tube as proposed in any of the embodiments of the first aspect above, wherein the temperature sensor 410 of the body temperature detection tube is electrically connected to the monitor.

[0056] In this embodiment, the temperature sensor 410 and the monitor are electrically connected via a wire 411. The wire 411 extends from between the inner diaphragm 310 and the outer diaphragm 320 into the temperature sensing cavity 330 and extends along the outer side of the ventilation tube 200. In this embodiment, the outer side of the ventilation tube 200 is provided with a protective layer, the end of which is connected to the outer diaphragm 320. A wire passage cavity is formed between the protective layer and the ventilation tube 200, and the wire passage cavity is connected to the temperature sensing cavity 330. This provides space for the wire 411 connecting the temperature sensor 410 and the monitor, preventing the wire 411 from coming into contact with the patient and causing an accident.

[0057] In this embodiment, the end of the wire passage cavity near the air inlet is provided with an outlet. The wire 411 of the temperature sensor 410 extends along the wire passage cavity to the outlet and then connects to the monitor through a connector. After use, the body temperature detection tube can be separated from the monitor by directly disconnecting the wire 411 connecting the temperature sensor 410 from the connector.

[0058] Because the intubation device is equipped with a specially designed temperature detection tube, it can establish a temporary breathing channel for patients during endotracheal intubation, bronchial intubation, or tracheotomy. At the same time, the outer diaphragm 320 can inflate to contact the inner wall of the patient's trachea or bronchus to form support. The heat-conducting wire 420 set in the temperature sensing cavity 330 can be closely attached to the inner wall of the outer diaphragm 320. The temperature sensor 410 can obtain the temperature of the heat-conducting wire 420, which can detect the temperature in the human trachea or bronchus in a non-contact manner and transmit the temperature information to the monitor for display, providing data support for the operator.

[0059] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
