Description

Technical Field

[0001] The utility model belongs to the field of analgesic pumps, and specifically relates to an analgesic pump that can be switched for use in two chambers. Background Technique

[0002] An analgesic pump is a medical device used to continuously deliver analgesic drugs. It is commonly used for postoperative analgesia treatment, especially in pain management after surgery. The analgesic pump can provide accurate drug doses to help patients achieve continuous and controllable analgesic effects. The working principle of the analgesic pump is to store the analgesic drug in a container and then slowly and continuously deliver the drug into the patient's body through an infusion tube and an infusion pump system, which can help patients avoid intermittent pain and reduce complications caused by neglecting pain.

[0003] A Chinese patent with the publication number CN216456343U discloses an analgesic pump, which includes a pump body, a first infusion tube, an antidote device, a second infusion tube, and a needle. The antidote device includes a housing, an antidote chamber, a switch assembly, a third infusion tube, and a fourth infusion tube. One end of the third infusion tube is connected to the pump body through the first infusion tube, and the other end of the third infusion tube is connected to the needle through the second infusion tube. The antidote chamber is connected to the third infusion tube through the fourth infusion tube. The switch assembly is used to control the on-off of the third infusion tube and whether the fourth infusion tube is connected to the third infusion tube, so that when the third infusion tube is a passage, the fourth infusion tube is not connected to the third infusion tube, and when the third infusion tube is an open circuit, the fourth infusion tube is connected to the second infusion tube through a part of the third infusion tube. The pump body infuses analgesics. When the patient has an overdose of anesthesia, the switch assembly is controlled to close the third infusion tube and open the fourth infusion tube so that the antidote in the antidote chamber is injected into the patient's body.

[0004] In view of the above-related technologies, the analgesics are infused through the provided pump body. When the patient has an overdose of anesthesia, the switch assembly is controlled to close the third infusion tube and open the fourth infusion tube so that the antidote in the antidote chamber is injected into the patient's body. However, during the use of the analgesic pump, it is inconvenient to sedate the patient, resulting in a poor state of the patient. The analgesia and sedation cannot be switched for use, thus affecting the physical recovery.

[0005] Therefore, we propose an analgesic pump that can be switched for use in two chambers to facilitate the solution of the problems raised above. Summary of the Invention
