[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0015] The utility model discloses an insulin pump needle exhaust device which is mainly used in the scenario where bubbles are always generated in a pipe near one end of a pump tube of an insulin pump close to a needle and the process of exhausting the bubbles is troublesome.

[0016] Reference Figure 1 and Figure 2 , an insulin pump needle exhaust device, comprising an islet pump body 1, a liquid reservoir 9 is provided on the outer wall of one side of the islet pump body 1, a pump tube 3 is connected to the outlet of the liquid reservoir 9, the end of the pump tube 3 away from the liquid reservoir 9 is connected to an infusion set 11, a needle 14 is installed on the infusion set 11, a mounting sleeve 4 is installed on the outer wall of the pump tube 3 close to the needle 14, a plurality of equally distributed fixing grooves are provided on the inner wall of the mounting sleeve 4, air bag rubber rings 5 ​​are provided on the inner walls of the plurality of fixing grooves, and the same air guide tube 8 is connected between the plurality of air bag rubber rings 5, a rubber plug 6 is provided on the outer wall of one side of the mounting sleeve 4, a puncture hole 7 is provided on the outer wall of one side of the rubber plug 6, and the position of the puncture hole 7 corresponds to the inlet position of the air guide tube 8.

[0017] Among them, the inner diameter of the air guide tube 8 arranged between the plurality of airbag rubber rings 5 ​​is not greater than 0.5 mm; utilizing the principle of a thinner pipe, as the inflation process proceeds, the plurality of airbag rubber rings 5 ​​will be gradually filled, and the gas can be squeezed forward in sections.

[0018] The inlet of the air guide tube 8 is located on one side of the plurality of airbag rubber rings 5 ​​, and the rubber plug 6 is located on the outer wall of the mounting sleeve 4 away from the needle 14 to ensure that the direction of pushing air is toward the needle 14 side.

[0019] During actual use, the airbag rubber ring 5 is located inside the mounting sleeve 4. When it is not inflated, the pump tube 3 passing through the mounting sleeve 4 is unobstructed. When the bubbles are discharged from the needle 14, the air guide tube 8 can be inflated through a syringe or other tools. As the inflation process proceeds, the airbag rubber ring 5 arranged inside will expand in sequence along the series air guide direction, automatically squeezing the gas in the pump tube 3, thereby pushing the gas forward along the pump tube 3 to squeeze out the bubbles at the needle 14.

[0020] Reference Figure 1 and Figure 4 In a preferred embodiment, the infusion set 11 is also provided with an outer patch 12 and an inner patch 13, wherein the outer patch 12 is made of a waterproof material, and the inner patch 13 is made of a soft, skin-friendly material.

[0021] Specifically, the outer layer patch 12 and the inner layer patch 13 can be used together. When the infusion set 11 is adhered to the patient's abdomen, the inner layer patch 13 made of skin-friendly material is adhered to the skin surface, while the outer layer patch 12 made of waterproof material surrounds and is attached to the outer periphery of the inner layer patch 13. This not only improves the patient's user experience, but also makes the adhesion between the infusion set 11 and the skin waterproof, so that the patient can still use it while taking a bath.

[0022] Reference Figure 1 and Figure 3 In a preferred embodiment, an extension sleeve 10 is provided at the connection between the pump tube 3 and the liquid reservoir 9, and the extension sleeve 10 is made of soft rubber material.

[0023] In actual use, as the pump tube 3 is used close to the body, the continuous bending of the pump tube 3 may cause the connection to bend or break, and the extension sleeve 10 can protect the connection.

[0024] Reference Figure 1 In a preferred embodiment, a key area and a display screen 2 are respectively provided on the islet pump body 1. In actual use, the display can be adjusted according to the patient's use, and the display is convenient.

[0025] Working principle: When in use, first take out the device from the packaging bag, and then observe whether there are bubbles near the needle 14 of the pump tube 3. If there are bubbles, the trachea 8 can be inflated through tools such as a syringe. As the inflation process proceeds, the internally arranged air bag rubber ring 5 will expand in sequence along the series air guide direction, automatically squeezing the gas in the pump tube 3, thereby pushing the gas forward along the pump tube 3 to squeeze out the bubbles at the needle 14. This process keeps the needle 14 in a sterile environment. After the exhaust is completed, the gas in the air bag rubber ring 5 is re-drawn and the injection is started. After the injection, the needle 14 is located under the skin, and the infusion set 11 is attached to the skin by the outer patch 12 and the inner patch 13. The islet pump body 1 is hung on a waist belt or other position through tools such as a hanging sleeve.

[0026] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
