The invention belongs to the technical field of retractors, in particular to an orthopedic retractor for hospital physical therapy and rehabilitation, comprising a traction frame, a mounting ring is welded and fixed in the middle of the traction frame, and a second Two bolts, the inside of the mounting ring is provided with a mounting head, one end of the mounting head is integrally formed with a fixed ring, the other end of the mounting head is integrally formed with a threaded ring, and the inner surface of the mounting ring passes through the The second bolt is fixedly installed with an inner protective ring; by designing a fixed block at the end of the second traction rope and the first traction rope and designing a connecting ring at the junction of the two fixed blocks, it is avoided that the tractor is used according to the user's It is inconvenient to adjust the length of the traction rope due to the different height of the patient, and it is inconvenient to use when the traction rope is too long or too short. The length between the first traction rope and the second traction rope can be adjusted according to the height of the rehabilitation person. At this time, the fixed block Slide on the inside of the connecting ring.

The invention discloses a medical sterile cotton swab pick-and-place device, which relates to the technical field of cotton swab pick-and-place, and comprises a sterile cotton swab and a storage block. A groove is opened on the upper surface of the storage block, and the sterile cotton swab is movably placed on the In the groove of the groove, the inner wall of the storage block is slidingly connected with two sliding plates up and down, and the left sides of the two sliding plates are fixedly connected with a first baffle plate and a second baffle plate, respectively. The right side of the first baffle abuts against the left side of the sterilized cotton swab near the leftmost end, and the second baffle is located on the vertical symmetry line of the two sterilized cotton swabs near the leftmost end, so The inner wall near the left end of the storage block is provided with a driving mechanism. In the present invention, through the cooperation between the above structures, a sterile cotton swab can be dropped out by simply pulling the pull arm once, so that the medical staff can take it. The groove portion provides a dustproof effect.

The invention discloses a dual-purpose water heating device capable of heating and heating water, comprising a dual-purpose gas water heater capable of heating and heating water. The dual-purpose water heating device capable of heating and heating water is characterized by further comprising an independently circulated heat supply system. The heat supply system comprises a hot water circulating pipeline and a heating device, the interior of the hot water circulating pipeline is full of circulating water, the water feeding end and the water discharging end of the hot water circulating pipelineare respectively communicated with a water feeding end and a water discharging end of the heating device, the hot water circulating pipeline is connected with a temperature detecting head and a heat exchange variable speed pump in series, the heat exchange variable speed pump can regulate the rotation speed according to the detected water temperature of the temperature detecting head, and a heat exchanger is arranged between the hot water circulating pipeline and the gas water heater. The invention is designed to provide a dual-purpose water heating device capable of heating and heating water, which can circularly supply heat on the hot water circulating pipeline by a hot liquid heated by a solar water heater, control the heat exchange between the hot liquid in the hot water circulating pipeline and the gas water heater capable of heating and heating water via the heat exchanger by utilizing the flow speed of the hot water, and optimize the gas usage amount of the gas water heater capable of heating and heating water.

The invention relates to a device for measuring and controlling a dew point temperature and an implementation method thereof. The device comprises a master controller, a sensor module, a touch screen, a humidification module, a refrigerating control circuit, a compressor, a heater and a control circuit of the heater. The sensor module comprises a temperature and humidity sensor and an A / D converter. The implementation method for measuring and controlling the dew point temperature includes a method for measuring the dew point temperature and an implementation method with the dew point temperature as a control target. The implementation method for measuring and controlling the dew point temperature includes the following steps of acquisition, calculation of the dew point temperature, calculation of errors of the dew point temperature, calculation of output of a PI controller and calculation the action time of a humidity execution mechanism. The device for measuring and controlling the dew point temperature and the implementation method thereof have the advantages that dew point temperature measurement precision is high, and the problem that when a humidity set value is the dew point temperature, relative humidity needs to be converted into the dew point temperature, and accordingly measurement precision is affected is solved.

A fan control method and device, and a fan, the method comprising: recognizing a current target gesture of limbs of a user in front of a fan based on an infrared array sensor provided on the fan, acquiring a target control mode corresponding to the target gesture, and implementing a corresponding control of the fan based on the target control mode. A current gesture of a user may be determined according to the infrared array sensor provided on the fan, thereby determining a control mode for a fan, making fan control smarter and more flexible. The present invention can perform control functions of a fan, including turning on and off, adjusting fan speed and adjusting angle of turning, according to user gesture, thereby allowing a user to no longer rely on a fan control panel or a remote control to control a fan, solving the problem with current fans of a user needing to bend over or squat down to operate a control panel, or losing or not being able to find a remote control, making operation inconvenient.

The invention relates to a preparation method of porous material reinforced bletilla striata dressing, which belongs to the technical field of biomedicine. The preparation method uses directional freezing of part of the Bletilla striata polysaccharide casting solution, pours the bletilla striata polysaccharide solution of the connecting layer on the upper part of the incompletely frozen Bletilla striata polysaccharide casting solution, and spreads insoluble gelatin sponge or medical oxidized cellulose on the top of the melted solution Gauze, under the action of the metal conductor, the porous material, the bletilla striata polysaccharide solution in the connecting layer and the bletilla striata polysaccharide casting solution are frozen into one, and then the porous material reinforced bletilla striata dressing is obtained through freeze-drying technology, which solves the problem that the existing bletilla striata dressing is easy to use in clinical medicine. It is soluble in water and difficult to stick to the wound. The materials used in the preparation method of the invention can all be degraded and absorbed, and are non-toxic to human bodies. The preparation method of the invention enhances the mechanical properties and operational performance of the bletilla striata dressing, and promotes the application of the bletilla striata dressing in the fields of surgery, wound repair, tissue engineering and the like.
