Description

Technical Field

[0001] The utility model relates to the technical field of medical catheters, in particular to a medical hose. Background Art

[0002] Medical-grade heat shrink tubing is essential when working with catheters, drains, tracheostomy tubes, and other medical devices, where surgeons are required to use cautery instruments or perform laparoscopic and endoscopic procedures.

[0003] The existing patent (publication number is CN212914163U) and the pipe joint, hose assembly and medical hose. This patent mentions that when the outer hose is connected to the first cavity section by gluing, since the proximal end face of the outer hose abuts against the annular section, the glue is not easy to overflow to the proximal cavity of the outer hose, thereby not forming a blockage and causing the subsequent inner hose to be unable to smoothly penetrate the inner cavity of the outer hose. The above patent mentions the gluing connection, which has very high requirements for the corresponding glue. At the same time, it is not easy for medical staff to carry and use glue to complete the connection. Because the situations faced in the process of medical work are different from those of patients, and the use of hoses is also different, two hoses are often required to be connected, which are mostly used in oxygen tubes, or two groups of hoses with different diameters are connected, which are often used in drainage tubes or urinary catheters.

[0004] Therefore, we propose a medical hose, which is conducive to quickly completing the connection of two sets of hoses with the same diameter or different diameters, and is conducive to improving the sealing of the connection between the two sets of hoses. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a medical hose, comprising a first hose, a second hose and a pipe joint, the first hose and the second hose are connected through the pipe joint, the first hose and the second hose are heat shrinkable tubes, a connecting block is provided in the middle of the inner wall of the pipe joint, the connecting block is respectively connected to an upper sealing tube and a lower sealing tube on the left and right, an upper window and a lower window are respectively opened on the outer wall of the pipe joint at positions corresponding to the upper sealing tube and the lower sealing tube, the first hose is nested in the gap between the inner wall of the pipe joint and the upper sealing tube, and the second hose is nested in the gap between the inner wall of the pipe joint and the lower sealing tube.

[0007] Further: the pipe joint is divided into two parts, an upper part and an lower part, and the pipe diameters of the upper and lower parts of the pipe joint are different.

[0008] Furthermore: the upper sealing cylinder and the lower sealing cylinder are connected to form a through cavity, and the through cavity is connected to the inner cavity of the first hose and the inner cavity of the second hose respectively.

[0009] Furthermore: the outer walls of the upper sealing cylinder and the lower sealing cylinder are both provided with textures for increasing friction.

[0010] Furthermore: the first hose and the second hose shrink inwards at high temperature and respectively wrap the upper sealing tube and the lower sealing tube.

[0012] 1) The medical hose of the utility model is provided with a pipe joint, an upper window, a lower window, an upper sealing tube and a lower sealing tube. The first hose and the second hose are respectively inserted and clamped into the corresponding two ends of the pipe joint, and then a high-temperature object is passed through the upper window and the lower window, so that the first hose and the second hose are contracted inwardly, and then a heat-sealing effect is formed on the upper sealing tube and the lower sealing tube, so that the first hose and the second hose are closed through the pipe joint, which is conducive to quickly completing the connection of two groups of hoses with the same diameter, and is conducive to improving the sealing of the connection between the two groups of hoses.

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the structures involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-5 The utility model provides a technical solution: a medical hose, comprising a first hose 2, a second hose 3 and a pipe joint 1, wherein the first hose 2 and the second hose 3 are connected through the pipe joint 1, the first hose 2 and the second hose 3 are heat shrinkable tubes, which are tubes that shrink when heated, and are longer than catheters, drainage tubes and tracheotomy tubes used in medicine, a connecting block 9 is arranged in the middle of the inner wall of the pipe joint 1, and the connecting block 9 is respectively connected to an upper sealing tube 6 and a lower sealing tube 7 on the left and right, and an upper window 4 and a lower window 5 are respectively opened at the positions of the outer wall of the pipe joint 1 corresponding to the upper sealing tube 6 and the lower sealing tube 7, by reserving the upper window 4 and the lower window 5 to pass through the high temperature, the outer wall of the heat shrinkable tube is deformed after passing through the high temperature and shrinkage problems, resulting in its structure being relatively fragile, making it easily affected by the external environment, leading to its breakage. At the same time, it also limits the shrinkage range of the heat shrink tube to ensure the strength of the hose connection. The first hose 2 is nested in the gap between the inner wall of the pipe joint 1 and the upper sealing tube 6, and the second hose 3 is nested in the gap between the inner wall of the pipe joint 1 and the lower sealing tube 7. The first hose 2 and the second hose 3 are respectively nested and inserted into the two ends of the pipe joint 1, and then a high-temperature object is passed through the upper window 4 and the lower window 5, so that the first hose 2 and the second hose 3 shrink inwardly, thereby forming a heat-sealing effect on the upper sealing tube 6 and the lower sealing tube 7, so that the first hose 2 and the second hose 3 are completely sealed through the pipe joint 1.

[0023] The pipe joint 1 is divided into an upper and lower part, and the pipe diameters of the upper and lower parts of the pipe joint 1 are different. By making the two ends of the pipe joint 1 into different sizes, when two groups of hoses of different sizes are connected, the hose with a larger diameter is connected to the end with a larger diameter of the pipe joint 1, and the hose with a smaller diameter is connected to the end with a smaller diameter of the pipe joint 1, and the heat sealing effect is achieved in the same way.

[0024] The upper sealing tube 6 and the lower sealing tube 7 are connected to form a through cavity 8 , and the through cavity 8 is connected to the inner cavity of the first hose 2 and the inner cavity of the second hose 3 , respectively. The first hose 2 and the second hose 3 are connected through the through cavity 8 .

[0025] The outer walls of the upper sealing tube 6 and the lower sealing tube 7 are provided with textures for increasing friction, and the textures increase the friction between the inner walls of the first hose 2 and the second hose 3 and the upper sealing tube 6 and the lower sealing tube 7 to prevent the first hose 2 and the second hose 3 from sliding off.

[0026] The first hose 2 and the second hose 3 shrink inwards at high temperature and wrap the upper sealing tube 6 and the lower sealing tube 7 respectively, so that the first hose 2 and the second hose 3 shrink inwards and wrap the upper sealing tube 6 and the lower sealing tube 7 respectively, thereby forming a sealing effect.

[0027] The working principle of the embodiment of the utility model is as follows: the first hose 2 is nested in the gap between the inner wall of the pipe joint 1 and the upper sealing tube 6, and the second hose 3 is nested in the gap between the inner wall of the pipe joint 1 and the lower sealing tube 7. The first hose 2 and the second hose 3 are respectively nested and inserted into the two ends of the pipe joint 1, and then a high-temperature object is passed through the upper window 4 and the lower window 5, so that the first hose 2 and the second hose 3 are contracted inwardly, and then a heat-sealing effect is formed on the upper sealing tube 6 and the lower sealing tube 7, so that the first hose 2 and the second hose 3 are closed by the pipe joint 1. When two groups of hoses of different sizes are connected, the hose with a larger diameter is connected to the larger end of the pipe joint 1, and the hose with a smaller diameter is connected to the smaller end of the pipe joint 1, and the heat-sealing effect is achieved in the same way.
