Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a device for regulating pain during perioperative period of minimally invasive surgery for lung nodules. Background Art

[0002] Pain control device is an analgesic pump. An analgesic pump is a medical device used to relieve pain. It helps patients reduce or eliminate pain by regularly and quantitatively administering analgesics. An analgesic pump usually consists of a medicine box containing analgesics or anesthetics, an electronic pump or a mechanical pump, a damping tube, a dosing port, a reservoir, a filter, a flow control tube and a protective sleeve. When using an analgesic pump, the drug is introduced into the patient's body through a specific route to maintain a stable drug concentration, thereby achieving a continuous analgesic effect. The analgesic pump allows patients to press themselves according to their own pain conditions to increase the additional drug infusion dose, which makes the treatment more individualized and can better meet the needs of different patients. Analgesic pumps are widely used in clinical practice for postoperative analgesia, labor analgesia, chronic pain treatment, and pain control in patients with malignant tumors. In addition, the use of an analgesic pump can help alleviate the adverse physiological reactions caused by pain, such as increased blood pressure and increased heart rate, thereby improving the quality of life of patients.

[0003] The analgesic pump is mainly composed of a body and a drug storage component. The main unit is also equipped with a display screen and operating buttons for adjusting the injection dose and flow rate. The operating buttons are directly pressed. During use, patients usually carry the analgesic pump with them or place it beside them. Therefore, when the patient is resting in bed or walking, the body position will change. As the patient's body parts move, the analgesic pump is easily squeezed. In this process, the button may be squeezed and misoperation may occur, resulting in improper use of the injection, excessive analgesia or insufficient dosage. Excessive analgesia may lead to an increase in the side effects of analgesics, such as nausea, vomiting, dizziness, etc., while insufficient dosage may not provide sufficient pain relief. In addition, some drugs may also pose risks because the amount of drugs increased due to accidental touch, which can easily affect the health and safety of patients. Summary of the invention
