Description

Technical Field

[0001] The utility model relates to the technical field of analgesic pumps, in particular to an analgesic pump dosing device for patients with severe neurological diseases. Background Art

[0002] A pain pump is a fluid infusion device that maintains a steady concentration of medication in the blood, which can help achieve better pain relief with less medication.

[0003] Publication No. CN215231049U discloses a dosing device for analgesic pumps. By applying pressure to a medicine infusion bottle, the medicine in the medicine infusion bottle can flow into the analgesic pump, thereby avoiding the nurses from repeatedly injecting the medicine, reducing the nurses' fatigue and dosing time, and reducing the probability of bacterial infection of the medicine and the analgesic pump. The pressure applied to the medicine infusion bottle is the force exerted by air pressure on it, and no manual force is required. However, the patent still has the following problems in actual use:

[0004] By applying pressure to the medicine bottle, the medicine in the medicine bottle can flow into the analgesic pump, which avoids the nurse's repeated injections to add medicine, reduces the nurse's fatigue and the time of adding medicine. However, in actual use, the pressurization of the medicine bottle is mainly achieved through the effect of atmospheric pressure. Most of the medicine bottles are made of soft materials, and there is a certain amount of air inside the medicine bottle in addition to the medicine. If the pressure of the medicine bottle is pressurized by atmospheric pressure, it is not easy to control the pressure of the medicine bottle, and the air inside the medicine bottle may be added to the inside of the analgesic pump, which may cause the air to be entered into the patient's blood vessels along the infusion tube on the analgesic pump, affecting its use.

[0005] A drug-adding device for an analgesic pump for critically ill neurological patients is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide an analgesic pump dosing device for critically ill neurological patients, so as to solve the problem proposed in the above-mentioned background technology that pressure is currently applied to the medicine bottle so that the medicine in the medicine bottle can flow into the analgesic pump, thereby avoiding the nurse's repeated injections for dosing, reducing the nurse's fatigue and dosing time. However, in actual use, the pressurization of the medicine bottle is mainly achieved through the effect of atmospheric pressure. The overall material of most medicine bottles is relatively soft, and there is a certain amount of air inside the medicine bottle in addition to the medicine. If the pressure is increased by atmospheric pressure, the pressure of the medicine bottle is not easy to control, and the air inside the medicine bottle may be added to the interior of the analgesic pump, which may cause the air to be input into the patient's blood vessels along the infusion tube on the analgesic pump, affecting its use.
