[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including required computer software. For injections of patients, injection devices are often required to perform injection operations on patients.

[0003] For example, application number 202021840446.2 discloses an auxiliary injection device for nursing, including a fixed plate, a guide rail is fixedly installed on the upper surface of the fixed plate, a lifting mechanism is arranged on the side of the guide rail, and a placement plate is arranged on the upper surface of the lifting mechanism. The auxiliary injection device for nursing described in the utility model is used in conjunction with the set guide rail and lifting mechanism. Lifting mechanisms are arranged on both sides of the guide rail. The outer surface of the slider slides up and down on the inner surface of the slide groove, thereby driving the placement plate to slide up and down, and the threaded hole and the fixed hole are fixed by a threaded rod. The patient's arm is placed on the upper surface of the flexible pad. The device can be used to provide injection treatment for patients of different heights, and the device can provide injection treatment for two patients at the same time. The bottom surface of the ring is connected to the bottom surface of the groove by a shock-absorbing spring, which can effectively reduce the impact of the patient's shaking during the injection process on the stability of the device.

[0004] However, although the injection device can be used to inject patients, it has a poor limiting effect on the patient's arm during injection, so that when injecting patients, the patient may move around due to pain, thereby reducing the injection treatment effect on the patient.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a nursing anti-tampering injection device is proposed. Utility Model Content

[0010] Furthermore, a clamping groove is provided at the connection position between the outer wall of the connecting block and the clamping block.

[0011] Furthermore, the outer wall profile of the block is in a "T" shape, and the limiting belt is elastic.

[0012] Furthermore, the length of the card slot is greater than the length of the card block, and the length of the cross section of one end of the card block is greater than the width of the cross section of the card slot.
