[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0025] Example 1

[0026] See Figure 1-4 The present embodiment provides a scalp vein indwelling needle protective cover, which includes a detachable shell 110 and a strap assembly, a protective cavity 416 is formed at the shell 110, the protective cavity 416 is used to cover the scalp vein indwelling needle, and the strap assembly is used to cooperate with the head of the child; one end of the shell 110 is formed into a spherical shape, and the other end is contracted to form a cone, and a limiting groove 315 is formed at one end of the shell 110 to form a cone, and the limiting groove 315 is used to cooperate with the external joint.

[0027] According to the solution provided in this embodiment, the shell 110 can protect the indwelling needle inserted into the scalp vein of the child, and prevent the child from accidentally touching or colliding with external objects and causing damage to the indwelling needle. The strap assembly can put the shell 110 on the child's head, so that the shell 110 can better form a fixed fitting relationship with the child's head.

[0028] Furthermore, the limiting groove 315 can limit the position of the external connector to prevent the external connector from swinging at the housing 110 when the child moves, causing the indwelling needle at the child's scalp vein to fall off, while also making it easier for medical staff to connect other infusion sets.

[0029] That is, when using the scalp vein indwelling needle protective cover, when the indwelling needle is inserted into the scalp vein of the child, the shell 110 is covered on the indwelling needle so that the puncture position is located at the center of the spherical part of the shell 110, and the external connector is placed in the limiting groove 315. Then, the strap assembly is used to fix the shell 110 to the head of the child, thereby protecting the scalp vein indwelling needle.

[0030] See Figure 1 and 3 A mating strip 311 is formed at the outer edge of the end of the shell 110 that contacts the child, and two plug holes 312 symmetrical about the symmetrical plane of the shell 110 are formed at the mating strip 311, and the two plug holes 312 are used to cooperate with the strap assembly.

[0031] Among them, the matching strip 311 can increase the contact area between the shell 110 and the child, thereby reducing the pressure on the contact surface between the shell 110 and the child, and preferably reducing the pressure of the shell 110 on the child. The plug-in hole 312 can facilitate the matching with the strap assembly to realize the wearing of the shell 110.

[0032] See Figure 1-3 The strap assembly includes a first strap 121 and a second strap 122 that are detachable and matable. One end of the first strap 121 is mated with the plug hole 312 at one end of the shell 110, and the other end is provided with a nylon hook strap 1211. One end of the second strap 122 is mated with the plug hole 312 at the other end of the shell 110, and the other end is provided with a nylon loop strap 2221. The nylon hook strap 1211 and the nylon loop strap 2221 are mated with each other.

[0033] The nylon hook strap 1211 and the nylon loop strap 2221 can be pasted together to achieve fixed cooperation between the first strap 121 and the second strap 122, so that they can form a restraining circle together with the shell 110, so as to be better fixed on the child's head.

[0034] See Figure 1 and 3 The other end of the first strap 121 on the same side as the nylon hook strap 1211 is provided with a first sub-snap button and a first female snap button at intervals, and the first sub-snap button is used to pass through the plug-in hole 312 and cooperate with the first female snap button.

[0035] Among them, by providing the first sub-snap button and the first mother snap button, the fixed fit between the first strap 121 and the shell 110 is preferably achieved.

[0036] See Figure 1-3 The other end of the second strap 122 located on the other side of the nylon loop 2221 is provided with a second sub-snap button and a second female snap button at intervals, and the second sub-snap button is used to pass through the plug hole 312 and cooperate with the second female snap button.

[0037] Among them, by providing the second sub-snap button and the second main snap button, the fixed fit between the second strap 122 and the shell 110 is better achieved.

[0038] See Figure 1 , 3 4, a plurality of bosses 313 are formed on the side of the shell 110 away from the child, and a plurality of air holes 314 connected to the protection cavity 416 are formed on the bosses 313.

[0039] Among them, by providing the ventilation holes 314, the ventilation of the shell 110 is better achieved, preventing long-term wearing from affecting the skin of the child.

[0040] It is understandable that the material of the housing 110 is polycarbonate.

[0041] Polycarbonate has good transparency and biocompatibility, can come into contact with human skin, and can facilitate medical staff to observe and monitor the status of the indwelling needle.

[0042] It is understandable that the first strap 121 and the second strap 122 are made of polyester fiber.

[0043] Among them, polyester fiber has good air permeability and comfort, which can better meet the needs of long-term wearing of the shell 110 on the child's head and improve the comfort of the child's wearing; and polyester fiber has good elasticity, which can reduce the restraint on the child's head.

[0044] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
