They have excellent high-temperature resistance, corrosion resistance, and pressure resistance, and are widely used in industries such as manufacturing, chemicals, machinery, and electronics. The structure of a metal hose usually consists of an outer metal mesh and an inner metal tube, which can resist external pressure and impact to a certain extent.

[0003] In the existing technology, during the use of medical metal tubing, the heat-conducting suction tube of the metal tubing is relatively good, but it is easily affected by the surrounding environment. In cold weather, the temperature of the liquid transported inside is low, which will affect the performance. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medical metal flexible tube includes a metal flexible tube with rubber connectors fixedly connected to both ends. A threaded sleeve is rotatably fitted at the connection between the metal flexible tube and the rubber connectors. A rubber protective sleeve is fixedly fitted on the wall of the metal flexible tube. A controller is fixedly connected at the connection between the metal flexible tube and the threaded sleeve. Multiple openings are provided on the wall of the rubber protective sleeve. A heating wire is electrically connected to the side wall of the controller. The heating wire extends into the interior of the rubber protective sleeve and passes through the multiple openings.

[0007] Preferably, a plurality of elastic protective buffer rings are fixedly connected to the wall of the rubber protective sleeve, and the elastic protective buffer rings have buffer gaps inside.

[0008] Preferably, the rubber protective sleeve is fixedly connected to a reinforcing connecting plate on the inner wall of the opening, and the heating wire extends into the interior of the reinforcing connecting plate.

[0009] Preferably, the reinforcing connecting plate has multiple heat-conducting metal sheets fixedly connected inside, and each of the multiple heat-conducting metal sheets has a connecting hole inside, with the heating wire passing through the heat-conducting metal sheet and located on the inner wall of the connecting hole.

[0011] Preferably, the threaded sleeve is fixedly connected to a rubber sealing ring on the inner wall of the annular groove, and the side wall of the connecting ring is fitted against the inner wall of the rubber sealing ring.

[0012] Compared with the prior art, the present invention provides a medical metal flexible tube, which has the following beneficial effects:

[0013] 1. This medical metal hose uses rubber connectors to ensure a tight seal at both ends, while threaded sleeves ensure a stable connection to the equipment. Rubber protective sleeves and elastic protective buffer rings enhance the pressure resistance of the hose wall, preventing deformation and ensuring stable gas-liquid transmission. The controller allows the heating wire to be energized, raising the temperature of the rubber protective sleeve and preventing it from hardening due to cold, thus maintaining its protective effect. Simultaneously, heat is transferred to the interior of the metal hose to heat the internal liquid, improving operational stability.

[0014] 2. The medical metal hose can improve the stability of the heating wire inside the rubber protective sleeve by strengthening the connecting plate, while the heat-conducting metal sheet can improve the heating effect of the heating wire.

[0015] 3. This medical metal hose allows for a stable connection between the rubber connector and the threaded sleeve via a connecting ring, while the ball bearings reduce friction and the rubber sealing ring improves the sealing performance of the connecting ring inside the threaded sleeve.

The side wall of the connecting ring 10 is fitted against the inner wall of the rubber sealing ring 12.

[0027] The connecting ring 10 enables a stable connection between the rubber connector 2 and the threaded sleeve 3, while the ball bearing 11 reduces friction and the rubber sealing ring 12 improves the sealing performance of the connecting ring 10 inside the threaded sleeve 3.
