[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] The terms used in the present application are merely for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0024] Please refer to Figure 1 , Figure 1 A temperature measuring catheter provided by an embodiment of the present application comprises a temperature sensor 7 arranged in a region close to a head 6 of the catheter and a multi-lumen tube having at least three lumens, the three lumens comprising an excretion lumen, a filling lumen and a temperature lumen, one end of the excretion lumen is connected to an excretion conical interface 1, one end of the filling lumen is connected to a filling conical interface 2, and a conical interface connected to one end of the temperature lumen is electrically connected to a third-party device through a temperature measuring lead. A balloon 5 in communication with the filling lumen is arranged in a region close to the temperature sensor 7, and a temperature measuring lead fixing cap 8 is arranged on the conical interface connected to one end of the temperature lumen. The filling conical interface 2 can also be connected to a one-way valve 3 to facilitate inflating and deflating the balloon 5 through the one-way valve 3 and the conical interface 2. The one-way valve 3 can be realized by using a one-way valve suitable for the catheter in the prior art.

[0025] The temperature measuring lead fixing cap 8 is preferably a cylinder, and can also be a shape similar to a cone with unequal circumferences at both ends. The temperature measuring lead fixing cap 8 is preferably made of acrylonitrile-butadiene-styrene copolymer (ABS) material. The temperature measuring lead fixing cap 8 is a cylinder because this can provide better connection strength, provide protection for the root of the lead by tightening and wrapping, and be more resistant to bending. Based on the inventor's practice, the temperature measuring lead fixing cap 8 of the present application preferably has a length of 1-2 cm. A too-short fixing cap cannot provide bending protection, and the root of the lead is prone to repeated bending and cracking. A too-long fixing cap is prone to brittle fracture.

[0026] Preferably, in order to achieve a better replacement effect, a notch groove or a notch is arranged at the edge of the relatively large end or either end of the temperature measuring lead fixing cap 8, so that when it is necessary to replace the temperature measuring lead fixing cap 8, the temperature measuring lead fixing cap 8 is directly torn off or removed through the notch groove, and then a new temperature measuring lead fixing cap is replaced. The notch groove includes but is not limited to a triangular, fan-shaped or sawtooth-shaped groove.

[0027] In a preferred embodiment, in order to make the temperature measuring wire fixing cap 8 have better fixing effect, a protrusion is arranged on the periphery of the tapered interface connected at one end of the temperature cavity, and a groove matched with the protrusion is arranged on the inner edge of the relatively large end or either end of the temperature measuring wire fixing cap 8, so as to facilitate the clamping of the protrusion in the groove, realize a more secure limiting function, and further improve the service life and sealing performance of the product.

[0028] Wherein, except for the specific description in the specific embodiments, the drainage cavity, the inflation cavity, the temperature cavity and other cavities and the interface and other components of the present application can be realized by using the existing technology and structure, and the connection of each cavity and interface can be integrally formed, bonded or other suitable connection mode. Wherein, the inflation tapered interface 2 is used for inflating and deflating the gas of the balloon 5 which is in communication with the inflation cavity. Specifically, when it is needed to fix the urinary catheter to a certain part of the patient, the balloon 5 is inflated through the inflation tapered interface 2, and based on the expansion of the balloon 5, the urinary catheter is fixed inside the urethra; when it is needed to take out the urinary catheter from the patient's body, the balloon 5 is deflated through the inflation tapered interface 2, so that based on the contraction of the balloon 5, the urinary catheter can be easily taken out from the inside of the urethra. Wherein, the balloon 5 can be wrapped on the outer wall of the urinary catheter and in communication with the inflation cavity. In addition, the connection between the balloon 5 and the urinary catheter cavity can include bonding (for example, bonding by using vulcanized silicone).

[0029] The present application covers the connection between the lead of the third party equipment (such as the monitor) and the corresponding tapered interface by the temperature measuring wire fixing cap 8, so that the tapered interface is tightly fitted and not easy to loosen, and effectively protects the connection which is easy to open and fall off, prolongs the service life and safety of the urinary catheter, and of course also increases the connection strength of the lead and the urinary catheter, so as to avoid or reduce the breakage or disconnection of the connection between the lead and the urinary catheter in the unintentional pulling.

[0030] Preferably, the temperature measuring wire fixing cap 8 is a transparent silicone cap, so as to better observe the use of the interface position covered by the temperature measuring wire fixing cap 8. In addition, a through hole for the temperature measuring wire to pass through is arranged in the silicone cap. In addition, the temperature measuring wire fixing cap 8 and the interface can also be fixedly connected in a bonding manner, so as to increase the connection strength of the interface.

[0031] Preferably, a plurality of strip-shaped protrusions can be arranged on the outer surface of the temperature measuring wire fixing cap 8 in the direction perpendicular to the radial direction, so as to facilitate the removal of the old fixing cap based on the non-smooth surface when the fixing cap needs to be replaced.

[0032] Preferably, for the one end of the temperature measuring wire fixing cap 8 with relatively larger outer periphery, an annular protrusion is arranged outside the one end, so that when the temperature measuring wire fixing cap needs to be replaced or fastened, it is more convenient to operate by screwing the temperature measuring wire fixing cap.

[0033] Preferably, the inner wall of the temperature measuring wire fixing cap 8 is in close contact with the tapered interface connected to one end of the temperature cavity, so as to improve the tightness of the wrapping and further prevent external substances from contaminating the wrapped interface.

[0034] Preferably, the third-party device is a monitor, and the tapered interface connected to one end of the temperature cavity is connected to the monitor connection joint 4 through the temperature measuring wire, and then is electrically connected to the monitor. Specifically, the temperature sensor 7 of the present application collects temperature data of the patient and transmits the temperature data to the third-party device through the temperature measuring wire, so that the third-party device performs corresponding action feedback based on the received temperature information. Among them, the temperature sensor 7 of the present application can adopt any sensor device suitable for the present application.

[0035] It should be noted that the above-described embodiments are only preferred embodiments of the present application, and all equivalent replacement modes or obvious modification modes of the implementation modes given in the specification can be reasonably predicted by those skilled in the art, and all of them can achieve the purpose of the present application, and are also included in the protection scope of the present application.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.

[0037] It is obvious for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
