Description

Technical Field

[0001] The utility model relates to the technical field of skin puncture, in particular to a skin puncture guide needle. Background Art

[0002] As people's living standards continue to improve, people pay more and more attention to their bodies; people monitor changes in their bodies through different scientific and technological means. For example, the proportion of people suffering from diabetes is increasing, and people have begun to use various blood glucose meters to monitor blood. The most commonly used and accurate measurement is: continuous glucose monitoring, which uses glucose sensors to continuously monitor the changes in glucose concentration in the interstitial fluid of subcutaneous tissues. It can provide more comprehensive blood sugar information and understand the characteristics of blood sugar changes. In order to facilitate the implantation of glucose sensors, soft needle implantation is generally used. The glucose sensor and the hollow soft needle are implanted into the body together; during the detection process, the soft needle will also remain in the human body; because the detection time is relatively long, the soft needle remains in the human body for a long time, which will cause certain damage to the human body. Utility Model Content

[0003] The utility model aims to provide a skin puncture guide needle to address the deficiencies of the prior art. The skin puncture guide needle can introduce a glucose sensor into the human body. During measurement, the skin puncture guide needle can be withdrawn from the human body to reduce damage to the human body.

[0004] A skin puncture guide needle comprises: a needle body and a needle head, wherein the needle head is arranged with a pointed end, the needle body comprises a bottom plate connected to the needle head, the two sides of the bottom plate are bent upward to form side plates, the side plates on both sides form a U-shape with the bottom plate, and a storage space for carrying a glucose sensor is formed inside; the front end of the side plate is arranged in an inclined or arc shape.

[0005] Furthermore, a protruding limiting block is provided at the rear end of the side plate.

[0006] Furthermore, the side surface of the needle is arranged in an outwardly convex arc shape.

[0007] Furthermore, the side surface of the needle is arranged at an inclination.

[0008] Furthermore, a rounded transition is adopted between the front end surface and the upper end surface of the side plate.

[0009] Beneficial effects of the utility model: the utility model adopts a U-shaped needle body, which is convenient for carrying the glucose sensor together and inserting it into the human skin, and convenient for withdrawing it from the human body; it is easy to use.

[0015] The utility model is described in detail below with reference to the accompanying drawings. Figures 1 to 3 shown.

[0016] Embodiment: A skin puncture guide needle comprises: a needle body 2 and a needle head 1, wherein the needle head 1 is arranged with a pointed end, and the needle body 2 comprises a bottom plate 21 connected to the needle head 1, and the two sides of the bottom plate 21 are bent upward to form side plates 22, and the side plates 22 on both sides form a U-shape with the bottom plate 21, and a storage space for carrying a glucose sensor is formed inside; the front end of the side plate 22 is arranged in an inclined or arc shape.

[0017] When the technical solution is implemented, the glucose sensor is first embedded in the accommodation space, and then the skin puncture guide needle is inserted into the skin, and the glucose sensor is then introduced into the subcutaneous tissue of the human body; then the skin puncture guide needle is withdrawn from the skin, and the glucose sensor is blocked by hand or other tools to keep it still. In this way, the purpose of inserting the glucose sensor into the human body and assembling it subcutaneously is achieved; it is easy to use. Secondly, in order to facilitate the insertion of the side plate 22, the front side of the side plate 22 is set to be curved or inclined.

[0018] Furthermore, a protruding limiting block 23 is provided at the rear end of the side plate 22 .

[0019] The limiting block 23 can be provided to prevent a novice from inserting the skin puncture guide needle too deeply into the skin and causing harm to the body.

[0020] Furthermore, the side surface of the needle 1 is arranged in an outwardly convex arc shape.

[0021] The side surface of the needle 1 is arranged to be an outwardly convex arc shape so that the area of ​​the needle 1 is larger than the triangular needle 1, which can effectively increase the strength of the needle 1.

[0022] Furthermore, the side surface of the needle 1 is arranged to be inclined.

[0023] The side surface of the needle 1 is arranged to be inclined so that the junction between the side surface and the upper end surface is very sharp, which facilitates piercing the skin and reduces pain.

[0024] Furthermore, a rounded transition is adopted between the front end surface and the upper end surface of the side plate 22 .

[0025] Use rounded corners to reduce scratches on the human body.

[0026] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
