Injection device

The present invention relates to a drug injection device, and more particularly to a device for injecting a drug into a patient by controlling the injection speed of one of the drugs without causing pain to the patient.

The implant was originally expressed as an alternative to restoring tissue missing in the human body. In dentistry, transplantation refers to a series of operations for implanting artificial teeth. Briefly, the graft is an operation for restoring dental function by replacing a missing tooth root by implanting a fixation device in the alveolar bone of the missing tooth and fixing a denture, wherein the fixation device acts as a tooth The roots are made of titanium that does not interfere with the human body.

In a typical transplant procedure, depending on the type of a fixation device, a predetermined drill bit is used to form a hole in one of the graft sites on the alveolar bone. The fixation device is implanted into the alveolar bone to perform the alveolar bone. Bone integration, an abutment is coupled to the fixation device, and eventually the abutment is covered by a final prosthesis.

For a typical prosthesis or denture, the teeth and bones will be damaged over time. In contrast, implants have the advantage of not damaging the tissue surrounding the teeth, having the same function and shape as natural teeth, not forming caries, and being able to be used semi-permanently.

In addition, transplant surgery will not only restore a single missing tooth, but also enhance the work of dentures in patients with partial anodontia or total anodontia. can. Transplant surgery improves the aesthetics of denture recovery, disperses excessive stress applied to a surrounding bone-supporting tissue, and can help stabilize a group of teeth.

On the other hand, the transplant operation may cause more pain to the patient because it is necessary to cut the gums during the transplantation process and drill a hole with a drill bit. Therefore, local anesthesia is essential for a surgical site during a transplant procedure.

Local anesthesia is performed by injecting an anesthetic solution into a surgical site using a syringe. In the case of local anesthesia, when one of the speeds of the injection of the anesthetic solution (i.e., the speed at which one of the anesthetic solutions is pressed) is faster, an excessive pressure is generated around a portion of the anesthetic solution to be injected, and the patient feels pain.

Therefore, the rate of injection of the anesthetic solution should be as slow as possible. However, when the injection speed of the anesthetic solution is decreased, the injection time of the anesthetic solution is increased, so the operator's time for holding the syringe is prolonged. When the operator has extended the time of holding the syringe, it is difficult for the operator to maintain a stable injection speed, and the patient may feel pain due to the shaking of the operator's hand.

In order to solve the above problems, it is necessary to develop a method of injecting an anesthetic solution using a separate pressing tool without directly pressing an anesthetic solution to complete an injection. Further, even if a separate pressing tool is used, there is still a need to develop an injection device capable of stopping the injection of the anesthetic solution or controlling the injection speed of the anesthetic solution immediately according to the state of the patient during the injection.
