Technical Field

The present invention relates to an injection device, and more particularly, to an electronic injection device.

Background

At present, electronic injection devices are widely used in interventional medicine, especially in cosmetic surgery, and are often used. The electronic injection device automatically controls the amount of fluid injected into human tissues through the arranged micropump so as to ensure the accuracy of the injected fluid amount.

Existing electronic injection devices typically comprise a body and an injection member that is relatively movable away from the body. One end of the injection component is communicated with the main body through a guide pipe. The other end of the injection component forms a medium end which can be directly implanted into the tissue of the user or implanted into the tissue of the user through an external water receiving light needle.

However, since the injection member can be moved away relative to the body, a special support body is usually required to support the injection member moved away from the body. This causes problems in using the electronic injection device.

First, when a medical staff wears a medical garment in some cases when using the electronic injection device, the face of the medical staff may be wrapped by the medical garment, and therefore, the medical staff cannot accurately observe the position of the support body, and a problem may occur in that the injection member is not accurately placed with respect to the support body.

Secondly, the top surface of the support body is generally flat, resulting in the injection member easily falling off the support body, which in turn results in the injection member being damaged or contaminated. In particular, it is easy for a medical staff member to touch the injection member during walking, so that the injection member is more easily dropped from the support body.

Referring to fig. 1 to 4, an electronic injection device according to a preferred embodiment of the present invention will be described in detail below, wherein the electronic injection device includes a device body 10 and an injection assembly 20, wherein the injection assembly 20 is removably mounted to the device body 10.

Specifically, the apparatus main body 10 includes a main body 11 and an electric part 12, wherein the electric part 12 is provided to the main body 11. The injection assembly 20 has a liquid pushing end 21 and a liquid outlet end 22. A cavity is formed between the liquid pushing end 21 and the liquid outlet end 22 and is used for installing an injector.

The body 11 can form a power source for pushing the syringe and can guide the injection liquid in the syringe to flow out therethrough after the electric part 12 is turned on.

Those skilled in the art will appreciate that the electrical portion 12 is provided including, but not limited to: micropump, control switch, etc.

Further, the electronic injection device comprises at least one guiding assembly 30, the guiding assembly 30 comprising a first guiding member 31 and a second guiding member 32, wherein the first guiding member 31 is arranged at the body portion 11, wherein the second guiding member 32 is arranged at an outer wall of the injection assembly 20, such that when the injection assembly 20 is arranged close to a corresponding portion of the body portion 11 where the first guiding member 31 is arranged, the second guiding member 32 can be guided by the first guiding member 31, thereby enabling the injection assembly 20 to be aligned at the body portion 11.

It will be appreciated that in this embodiment, since the body portion 11 itself forms the location for placing the syringe assembly 20, there is no need to specially add a support member for supporting the syringe assembly 20.

In addition, in the process of placing the injection assembly 20 on the body part 11, due to the guidance of the guide assembly 30, even if the user has poor sight, the injection assembly 20 can be positioned at the corresponding position of the body part 11 under the guidance of the guide assembly 30.

In one embodiment, the first guide member 31 and the second guide member 32 of the guide assembly 30 are respectively provided as members capable of forming a magnetic field, such as magnets. And the magnetic field formed by the first and

second guide members

31, 32 enables the injection assembly 20 to be subjected to an attractive force tending to close the body portion 11 when the injection assembly 20 is close to the body portion 11, thereby enabling the injection assembly 20 to be aligned.

On the other hand, since the injection unit 20 and the main body 11 can be attracted to each other by the first guide member 31 and the second guide member 32, the injection unit 20 can be stably fixed to the main body 11. In this way, the injection assembly 20 is prevented from being detached from the body portion 11.

Preferably, in one embodiment, the electronic injection device comprises at least two guide assemblies 30, wherein the first guide member 31 of one guide assembly 30 and the first guide member 31 of the other guide assembly 30 are disposed on the body portion 11 and are disposed behind the body portion 11 to generate magnetic fields with opposite magnetic induction directions, that is, if the first guide member 31 and the second guide member 32 are disposed as strip magnets, the first guide member 31 and the second guide member 32 are disposed on the body portion 11 in opposite directions.

Correspondingly, one of the second guide members 32 and the other of the second guide members 32 provided on the injection assembly 20 at this time can generate magnetic fields having opposite magnetic induction directions after being provided on the injection assembly 20, and the second guide members 32 and the first guide members 31 can attract each other when the second guide members 32 and the first guide members 31 approach each other in a predetermined posture. In this way, the injection assembly 20 can be stably supported on the body portion 11 only when the injection assembly 20 is placed on the body portion 11 toward a preset attitude.

Thus, by adjusting the height of the supporting surface supporting the injection assembly 20, after the injection assembly 20 is placed on the body 11, as long as the liquid outlet end 22 of the injection assembly 20 is always kept at a height higher than the liquid pushing end 21, the injection liquid can be prevented from flowing out.

Preferably, the electronic injection device further comprises a limiting structure 40, wherein the limiting structure 40 is implemented to comprise a first limiting structure 41 and a second limiting structure 42, wherein the first limiting structure 41 is disposed on the body portion 11, and the second limiting structure 42 is disposed on the injection assembly 20, so that the injection assembly 20 is limited in the transverse direction after the injection assembly 20 is placed on the body portion 11 through the first limiting structure 41 and the second limiting structure 42.

At this time, since the injection assembly 20 is restricted by the guide member 30 in the longitudinal direction, the injection assembly 20 can be stably supported to the body part 11.

In one embodiment, the first position-limiting structure 41 is implemented to include at least one position-limiting protrusion integrally extending from the body portion 11. Correspondingly, the second limit structure 42 is implemented as a limit groove provided on the injection assembly 20. When the injection assembly 20 is not used, the user can directly align the retaining groove with the retaining protrusion, so that the injection assembly 20 can be supported on the body 11. It is worth integrating that, because the guiding component 30 is provided, when a user places, the injection component 20 is guided by the guiding component 30, so that the limiting groove on the injection component 20 can automatically correspond to the limiting protrusion.

In another embodiment, the limiting protrusion is disposed on the injection assembly 20, and the limiting groove is disposed on the body 11.

In a variant of this embodiment, two stop lugs are provided on the injection assembly 20. The body 11 is provided with a limit groove and two slots 43 disposed at two ends of the limit groove and communicated with the limit groove. After the injection assembly 20 is placed in the retaining groove, it is retained in the retaining groove in a side-lying manner. At this time, the two limiting protrusions are clamped on the limiting grooves and the step portions of the clamping grooves.

It is worth mentioning that the width of the locking groove 43 is larger than the width of the limiting groove.

In this embodiment, the first limiting structure 41 is disposed at the top of the main body 11, and the liquid outlet end 22 of the injection assembly 20 on the main body 11 is higher than the liquid pushing end 21 of the injection assembly 20 on the main body 11.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are given by way of example only and are not limiting of the utility model. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
