Description

Technical Field

[0001] The utility model relates to the technical field of medical device detection, in particular to a tube sleeve air leakage detection device. Background Art

[0002] At present, some medical instruments need to install tube sleeves inside, and these tube sleeves can play a role in isolating radiation sources. Generally, radiation sources will produce radioactive gases. Due to the complex structure of the tube sleeves, they are generally assembled from separate parts, and the quality of the assembly process determines the isolation performance of the tube sleeves. However, the air tightness of the tube sleeves cannot be known by visual observation. Therefore, air tightness tests are generally required before the tube sleeves leave the factory.

[0003] In traditional air tightness tests, all leak prevention work is generally carried out manually, with low efficiency and possible misdetection and misjudgment. Summary of the Invention

[0004] In order to overcome the disadvantages and deficiencies in the prior art, the purpose of the utility model is to provide a tube sleeve air leakage detection device, which can automatically detect air leakage of medical tube sleeves with higher efficiency and higher accuracy.

The fixed fixture is arranged on the lifting platform and is used to fix the tube sleeve; the liquid storage tank is used to fill the detection liquid. The lifting platform is located in the liquid storage tank, and the platform lifting mechanism is used to drive the lifting platform to lift in the liquid storage tank. The pressure detection mechanism is used to detect air leakage of the tube sleeve to be detected fixed on the fixed fixture.

[0007] Among them, the platform lifting mechanism includes a lifting driving part, a connecting frame, and an L-shaped frame. The lifting driving part is installed on the frame, the connecting frame is connected to the output end of the lifting driving part, the upper end of the vertical part of the L-shaped frame is connected to the connecting frame, and the lifting platform is installed on the upper end surface of the horizontal part of the L-shaped frame.

[0012] Advantages of the present utility model:

When in use, the tube sleeve to be detected is placed on the fixture, and the lifting platform fixes and seals the tube sleeve to be detected on the fixture and connects the tube sleeve to be detected with the pressure detection mechanism.

[0020] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following describes the detailed implementation manners of the present utility model with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0022] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0023] At present, some medical instruments need to install a tube sleeve inside, and these tube sleeves can play a role in isolating the radiation source. Generally speaking, the radiation source will produce radioactive gas. Since the structure of the tube sleeve is complex and it is generally assembled from separate parts, the quality of the assembly process determines the isolation performance of the tube sleeve. However, the airtightness of the tube sleeve cannot be known by visual observation. Therefore, an airtightness test is generally required before the tube sleeve leaves the factory.

[0024] In the traditional airtightness test, the work of preventing leakage is generally carried out manually by hand, with low efficiency and possible misdetection and misjudgment.

[0025] To solve the above problems, this embodiment discloses a tube sleeve air leakage detection device, which includes a frame 100, a fixing fixture 112, a liquid storage tank 101 arranged on the frame 100, a lifting platform 103, a platform lifting mechanism 108, and a pressure detection mechanism 102 located on one side of the frame 100. The fixing fixture 112 is arranged on the lifting platform 103, and the fixing fixture 112 is used to fix the tube sleeve; the liquid storage tank 101 is used to fill the detection liquid, the lifting platform 103 is located in the liquid storage tank 101, the platform lifting mechanism 108 is used to drive the lifting platform 103 to lift in the liquid storage tank 101, and the pressure detection mechanism 102 is used to detect the air leakage of the tube sleeve to be detected fixed on the fixing fixture 112.

[0026] Specifically, a tube sleeve air leakage detection device of the present utility model is provided with a fixing fixture 112, a solution tank 101, a lifting platform 103, a platform lifting mechanism 108 and a air pressure detection mechanism 102. During use, the tube sleeve to be detected is placed on the fixing fixture 112, and the lifting platform 103 fixes and seals the tube sleeve to be detected on the fixture and connects the tube sleeve to be detected with the air pressure detection mechanism 102. Subsequently, the platform lifting mechanism 108 drives the lifting platform 103 to descend, so that the tube sleeve to be detected is completely immersed in the solution tank 101, and the air tightness of the tube sleeve to be detected is detected through the air pressure detection mechanism 102, realizing the full-automatic air leakage detection of the medical tube sleeve, with higher efficiency and higher accuracy.

[0027] It should be noted that the structure of the air pressure detection mechanism 102 in this embodiment and the working principle of detecting the air pressure of a sealed object belong to the prior art and will not be elaborated here.

[0028] Specifically, the platform lifting mechanism 108 includes a lifting driving member 109, a connecting frame 110 and an L-shaped frame 111. The lifting driving member 109 is installed on the machine frame 100, the connecting frame 110 is connected to the output end of the lifting driving member 109, the upper end of the vertical part of the L-shaped frame 111 is connected to the connecting frame 110, and the lifting platform 103 is installed on the upper end surface of the horizontal part of the L-shaped frame 111. In this embodiment, the lifting driving member 109 is preferably a cylinder. By driving the L-shaped frame 111 to lift and lower through the lifting driving member 109, the lifting and lowering of the lifting platform 103 in the solution tank 101 is realized. In addition, in order to ensure that the lifting and lowering of the L-shaped frame 111 does not conflict with the solution tank 101, the length of the vertical part of the L-shaped frame 111 in this embodiment is not less than the depth of the solution tank 101.

[0029] Specifically, the lifting platform 103 includes a platform bottom plate 104, a sealing mechanism 105 installed on both sides of the platform bottom plate 104 and a clamping cylinder 107 installed around the fixing fixture 112. Before the air pressure detection mechanism 102 detects the tube sleeve, the clamping cylinder 107 needs to clamp and fix the tube sleeve placed on the fixing fixture 112, and then the sealing mechanism 105 plugs the corresponding through holes of the tube sleeve. The sealing mechanism 105 includes a sealing driving member 106 and a sealing piston 113 installed on the sealing driving member 106. The sealing driving member 106 is installed on the platform chassis, and the sealing driving member 106 is preferably a cylinder.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
