Description

Technical Field

[0001] The present invention relates to the technical field of gypsum preparation devices, and particularly to a gypsum preparation device for treating traumatic fractures in hand and foot surgery. Background Technique

[0002] Gypsum is a traditional Chinese medicinal material for clearing heat and purging fire, which has the effects of quickly reducing fever, relieving thirst and restlessness, etc., and is commonly used to treat problems such as persistent high fever, lung heat cough, and skin swelling and scald. This white mineral medicinal material is mainly produced in Yingcheng, Hubei, Fengyang, Anhui, and Dingxi, Gansu, etc. Among them, the gypsum produced in Yingcheng, Hubei has relatively good quality due to its high purity and few impurities. Raw gypsum has a strong heat-clearing effect, which can not only clear the excess heat in the body but also dissipate heat. It is particularly effective for persistent high fever and restlessness and thirst caused by excessive fire in the lung and stomach, and is an important medicinal material for treating these symptoms. After calcination, the properties of gypsum turn to astringency, and external application can promote wound healing, and is commonly used to treat skin ulcers and eczema.

[0003] Among them, the "medical auxiliary device for treating orthopedic fracture gypsum" disclosed in the patent application number "CN113797025B" is also an increasingly mature technology. It includes a protection mechanism, a cutting mechanism, a bending part shearing mechanism A, and a bending part shearing mechanism B. Among them, the cutting mechanism cooperating with the protection mechanism effectively cuts the straight part of the gypsum cylinder and the corresponding inner lining gauze for protecting the limb fracture, and the protection mechanism protects the body surface from being cut by the cutting mechanism that overcuts the gypsum. The present invention cuts and disassembles the gypsum at the fracture of the patient through the cooperation of the protection structure and the cutting mechanism, effectively protecting the patient's body surface from being cut by the cutting mechanism due to the personal factors of the operator of the cutting mechanism, having high safety, and at the same time having low requirements for the cutting and disassembly experience of the operator for removing the gypsum, and being suitable for different operators to use.

[0004] Medical staff need to manually mix gypsum powder, and the proportioning accuracy depends on experience, which easily leads to unstable setting time.

[0055] Working principle:

[0056] Step 1: First, perform quantitative batching. The gypsum powder and water are respectively stored in the storage housing 202. The opening and closing of the feeding baffle 206 are driven by the first driving motor 205 to control the precise feeding of the raw materials. The feeding shell 203 and the feeding slot 102 cooperate to ensure that the gypsum powder evenly falls into the dispensing cylinder 1 according to the preset ratio;

[0057] Step 2: Next, perform mixing and stirring. First, perform primary stirring. The first stirring mechanism 3 adjusts the position of the stirring blade 305 through the electric telescopic rod 301, and the second drive motor 303 drives the rotating shaft 304 to rotate at a high speed, realizing the preliminary mixing of gypsum powder and water in the dispensing cylinder 1;

[0058] Secondary stirring: The mixed material enters the mixing housing 103. The third drive motor 501 drives the stirring shaft 502 and the scraping plate 504 to rotate, further mixing evenly, and scraping the residual gypsum on the inner wall to reduce waste.

[0059] Step 3: Then, perform constant temperature and humidity control. The constant temperature control mechanism 4 monitors the environmental parameters in the mixing housing 103 in real time through the temperature sensor 403 and the humidity sensor 405. The temperature regulator 407 and the humidifier 408 automatically adjust the environmental temperature and humidity according to the feedback data to ensure the stable setting time of gypsum and avoid low-temperature delay or high-temperature premature curing.

[0060] Step 4: Sterile discharging. The mixed gypsum is output through the sterile discharging funnel 602. The operator pushes the grip 607 to drive the baffle 603 to open. The telescopic spring 605 and the limit frame 606 ensure the smooth opening and closing of the baffle 603, realizing contactless material receiving and avoiding the risk of hand contamination and nosocomial infection.
