Multifunctional medical sponge capable of flexibly adjusting anesthesia and analgesic effect

Abstract

The invention discloses a multifunctional medical sponge capable of flexibly adjusting the anesthesia and analgesic effect. The sponge comprises a peripheral anesthesia functional layer, an intermediate hemostatic antibacterial anti-inflammatory functional layer and a surface bonding layer, the intermediate hemostatic antibacterial anti-inflammatory functional layer is located in the middle of thesurrounding anesthetic functional layer, and the surface bonding layer comprises a first connecting layer and a second connecting layer; the lower surface of the first connecting layer is fixedly connected with the intermediate hemostatic antibacterial anti-inflammatory functional layer; the lower surface of the second connecting layer is fixedly connected with the surrounding anesthetic functional layer; the upper surface of the first connecting layer and the upper surface of the second connecting layer are bonded to each other. A sponge design structure effectively avoids direct contact between an anesthetic agent and a wound, causes interference with the efficacy of anti-hemostatic anti-inflammatory drugs, greatly improves the therapeutic effect of the pharmacodynamic function in eachefficacy layer, increases the drug efficiency utilization rate, and reduces the raw material cost. According to the healing and recovery of the wound itself of a patient, the surrounding anesthesia functional layer can be exchanged separately, the flexible applicability is high, and excessive side effects of anesthesia are avoided.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a multifunctional medical sponge with ingenious design and structure, convenient and flexible use. Background technique [0002] Anesthesia refers to a state that allows patients to undergo surgery or invasive procedures without pain and discomfort. Generally speaking, anesthesia is a kind of reversible functional inhibition of the central nervous system and / or peripheral nervous system produced by drugs or other methods, which is mainly characterized by loss of sensation, especially pain sensation. However, surgical anesthesia also has a validity period. After the operation is completed, when the anesthesia carried out before the operation fails, the patient will feel pain. The traditional method of relieving pain is to take or inject painkillers to the patient, but these drugs have a certain degree of side effects, and are prone to addiction, causing great harm to the patient'...
