The invention belongs to the technical field of photoacoustic response antibacterial dressings, and discloses PDA (at) Ag (at) Ag2S / SA / F68 / F127 antibacterial temperature-sensitive hydrogel as well as a preparation method and application thereof.The PDA (at) Ag (at) Ag2S / SA / F68 / F127 antibacterial temperature-sensitive hydrogel can complete conversion of gel and sol under the condition of 4-60 DEG C, PDA (at) Ag (at) Ag2S nano-enzyme is constructed by means of an in-situ growth method, a PDA (at) Ag (at) Ag2S nano-composite material can generate electron-hole pairs under photoacoustic combination, then reactive oxygen species (ROS) is generated, and the antibacterial temperature-sensitive hydrogel can be used for preparing antibacterial temperature-sensitive hydrogel. The photoacoustic response antibacterial effect is realized. Meanwhile, PDA (at) Ag (at) Ag2S has peroxidase (POD)-like activity, and the material can catalyze endogenous hydrogen peroxide (H2O2) in a common wound microenvironment with the pH value of 7-8 to generate reactive oxygen species (ROS) with high toxicity, such as hydroxyl free radicals (. OH), so that efficient killing of various bacteria under photoacoustic combination is realized. Synthesis conditions are mild, and the process is simple, economical and feasible. The hydrogel has thermosensitivity, can resist inflammation, stop bleeding and relieve wound pain, does not loosen after absorbing seepage, is free of residues and does not adhere to a wound surface when being removed, and a new way is provided for developing novel medical dressings for treating drug-resistant bacterial infection wounds.

The invention discloses a traditional Chinese medicine composition, a plaster and a preparation method and application thereof. The traditional Chinese medicine composition comprises the following raw materials in parts by weight: 25-60 parts of fennel, 25-60 parts of semen plantaginis, 25-60 parts of fried semen raphani, 50-150 parts of fried lindera aggregata and 50-150 parts of piper cubeba. The prepared traditional Chinese medicine composition, namely the combined spicebush root-siza powder, can improve complications such as postoperative urinary retention, abdominal distension, anal pendant expansion, wound pain, hemafecia, seepage and edema of a patient, can promote postoperative wound healing, effectively shortens the hospitalization days, and fundamentally solves the problems of surgical pain and difficult healing of the patient.

The utility model discloses a kind of wound decompression nursing pads, including nursing pad main body, nursing pad main body is equipped with the hollow portion for corresponding with wound and the slot for fixing drainage tube, hollow portion is through the upper and lower surfaces of nursing pad main body, slot is set in the upper surface of nursing pad main body.The nursing pad main body of the utility model is equipped with hollow portion, when using, by the hollow portion and the wound of patient corresponding, avoid the wound of patient in body position change or sick lateral decubitus process to be pressed and rub, to avoid appearing wound pain aggravation, ensure that wound tissue has normal healing environment, solve the problem that body position changes difficultly caused by postoperative pain.In addition, the nursing pad main body of the utility model is also equipped with the slot being communicated with hollow portion, the range of activity of drainage tube can be limited by being placed in slot to drainage tube, prevent pipeline from bending when body position changes, ensure the patency of drainage system.

The utility model discloses a kind of anti-pulling drainage tube fixing devices, belong to medical instrument technical field, to solve the existing drainage tube fixing mode due to lack of mechanical locking and stress blocking mechanism, leading to pipeline easy axial slip, pulling force direct conduction to the problem of wound. The device includes wound protection component, drainage pipeline component and locking assembly;Drainage pipeline component passes through wound protection component, locking assembly is sleeved on pipeline and is fixed in distal end skin, and relaxation buffer tube section is formed between the two;Locking assembly contains shell, pressing cap and elastic piece, there is bearing groove in shell, and elastic piece pushes pressing cap and forms mechanical clamping force by compressing pipeline, limit pipeline axial displacement. The device is cooperated by distal end mechanical locking and intermediate buffer, and pulling force is transferred to distal end skin, cutting off force to the conduction of wound, avoid wound pain, tear, locking stable and convenient for observing wound, applicable to postoperative and intensive care drainage tube fixing.

The utility model discloses a dressing change device, including base, one end of base top is fixed with first standpiece, and the other end of base top is fixed with second standpiece, and the top of two first standpieces and two second standpieces is connected with medicine placing plate, and medicine placing plate is slidably arranged in the top of first standpiece and second standpiece along horizontal direction, and the area between first standpiece and second standpiece of base top is provided with garbage can for storing medical waste, the surface of two second standpieces is provided with adjustable mounting plate of liftable, and the inside liftable of mounting plate is provided with clamping plate, and the area between the top of clamping plate and mounting plate inner wall forms the clamping area for clamping bed board, this dressing change device can be firmly connected with the bed board of patient, guarantees the device stable when changing dressings and does not shake, and when changing dressings, the patient does not need to move the body, and the limbs can be comfortably supported on the medicine placing plate, avoid the pain and discomfort of wound because of body moving.

Described herein are methods and kits for locally treating pain in a patient in need thereof. The methods may include topically administering multiple doses of at least one pain management agent in a solution to a human patient by perfusing the at least one pain management agent at a wound, wherein the administration provides continuous pain treatment to the patient for at least 24 hours, at least 48 hours, at least 72 hours, or at least 96 hours.

The invention discloses a wound pain management scheme generation method based on game equilibrium optimization. The method comprises the following steps: S1, collecting an individual data set of a patient; s2, constructing a multivariable interaction model for wound pain management based on the acquired patient individualized data set; s3, generating an initial grey wolf population by using the patient individualized data set and the multivariate interaction model, wherein each individual in the initial grey wolf population represents a pain management scheme; s4, defining a revenue function of each variable and calculating an equilibrium solution; s5, performing iterative optimization on the grey wolf population based on a grey wolf optimization algorithm, and adjusting positions and fitness values of individuals in the grey wolf population by introducing a game equilibrium analysis result as a dynamic constraint condition to gradually approach a global optimal pain management scheme; and S6, outputting an optimal pain management scheme finally output by the grey wolf optimization algorithm to clinical medical care personnel in a suggestion form. The reliability and the practicability of a treatment scheme are remarkably improved.
