Description

Technical Field

[0001] The utility model relates to the field of medical products, in particular to an adsorption and matching structure of a flexible tube body. Background Art

[0002] In medical flexible tubes (for extracting test liquids), the hardness is relatively low. Current practices generally involve collecting the test liquid through the flexible tubes, but due to their low hardness, they generally require a rigid support to support them separately.

[0003] Existing flexible pipe bodies are generally produced by two sets of molds for the rigid support and the flexible pipe body, respectively. The rear ends of the rigid support and the flexible pipe body are then fixed (for example, with glue, screws, etc.). This involves many steps and the mold cost is high, so the production cost of the corresponding flexible pipe body is also high. Utility Model Content

[0004] The main purpose of the utility model is to propose an adsorption matching structure of a flexible tube body, which aims to improve the matching relationship between the flexible tube body and the pump body. The matching of the flexible tube body can be achieved without the need for additional hard brackets. The flexible tube body and the hard bracket are not produced as one piece. At the same time, the test liquid can be collected by a collector, reducing secondary pollution during the collection process.

[0005] To achieve the above-mentioned purpose, the present invention provides an adsorption and matching structure of a flexible pipe body, comprising:

[0006] A covering portion, wherein the covering portion is protrudingly provided with a limiting head, and the limiting head is provided with a channel;

[0007] The flexible tube body is provided with an inner cavity, and the rear end of the flexible tube body is provided with a limiting groove for the limiting head to extend into.

[0008] The collector is connected to the inner cavity or is connected to the inner cavity through a pump body, and the pump body is used to transport the liquid in the inner cavity to the collector.

[0009] In the actual design, the rear end of the flexible tube body of the covering part plays a supporting role. At the same time, the cooperation of the limit head and the limit groove realizes the fitting positioning of the flexible tube body and the rear end of the covering part. At the same time, when the pump body is started, negative pressure adsorption will be formed between the limit head and the limit groove, thereby ensuring the mutual positioning between the flexible tube body and the covering part, and thus ensuring that the pump body can transport the test liquid into the collector.

[0024] As Figures 1 to 3 shown, an adsorption and fitting structure of a flexible tube body includes:

[0025] A covering part 1, the covering part 1 is convexly provided with a limiting head 3, and the limiting head 3 is provided with a channel;

[0026] A flexible tube body 2, the flexible tube body 2 is provided with an inner cavity 21, and the rear end of the flexible tube body 2 is provided with a limiting groove 4 for the limiting head 3 to extend into,

[0027] A collector, the collector is communicated with the inner cavity 21 or is communicated with the inner cavity 21 through a pump body, and the pump body is used for conveying the liquid in the inner cavity 21 into the collector.

[0028] In actual design, the covering part 1 plays a supporting role for the rear end of the flexible tube body 2. At the same time, through the cooperation of the limiting head 3 and the limiting groove 4, the fitting and positioning of the rear end of the flexible tube body 2 and the covering part 1 are realized. At the same time, when the pump body is started, a negative pressure adsorption will also be formed between the limiting head 3 and the limiting groove 4, thereby ensuring the mutual positioning between the flexible tube body 2 and the covering part 1, and further ensuring that the pump body conveys the test liquid into the collector (reducing secondary pollution).

[0029] Specifically, the limiting head 3 includes a column body 3a and a convex seat 3b provided at the front end of the column body. The outer diameter of the convex seat 3b is larger than the outer diameter of the column body. The limiting groove 4 is provided with a column groove 4a matching with the column body, and the limiting groove 4 is further provided with a clamping groove 4b matching with the convex seat 3b. Through the structure of the limiting head 3 with a larger lower part and a smaller upper part, the positioning between the flexible tube body 2 and the covering groove is realized.

[0030] In the embodiment of the present utility model, the lower end wall of the convex seat 3b is arc-shaped. First, it can increase the contact area between the flexible tube body 2 and the limiting head 3. At the same time, it is also convenient for the limiting head 3 to extend into the limiting groove 4.

[0031] Specifically, the rear end of the column body is provided with a semi-circular part 51, and the semi-circular part is gradually reduced in diameter from the rear end of the main body to the front end. The flexible tube body 2 is provided with a semi-circular groove 52 matching with the semi-circular part, further increasing the contact area between the covering part 1 and the flexible tube body 2.

[0032] In the embodiment of the present utility model, the pump body 6 is provided with a fluid inlet 61 and a fluid outlet 62.

[0033] Specifically, when the pump body 7 is a liquid pump, the fluid inlet of the pump body is communicated with the channel, and the fluid outlet is communicated with the collector, that is, the liquid is directly pumped into the collector.

[0034] In the embodiment of the present utility model, when the pump body is an air pump, the collector 7 is provided with a connection inlet 71 and a connection outlet 72. The connection inlet is communicated with the channel, and the connection outlet is communicated with the fluid inlet of the pump body, so as to realize the negative pressure to pump the liquid to the collector. In a specific structure, the air pump can be provided with a predetermined valve body to prevent the liquid from entering the air pump. For example, for negative pressure, when the negative pressure reaches a predetermined value, the air pump stops. However, due to the negative pressure, the collector will still convey the liquid in the inner cavity 21 to the collector. When the air pressure in the collector resumes to the predetermined value, the air pump works, thus realizing the negative pressure extraction of the liquid.

[0035] Specifically, the limiting head 3 and the covering part 1 are integrally formed or separately installed.

[0036] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
