A surface suture device for skin wound has two supporting tapes arranged at both side of wound and a basic band with multiple sets of C-shaped suture thread guiders with C-shaped hole for limiting the suture thread to pass through it. Its advantages are uniform suture force and small residual scar.

The invention provides a disposable universal rotating part for clamping connection of a cervical clamp and an ultrasonic probe. The rotating part has a simple and easily operated structure, avoids troubles of cleaning and sterilizing after operation, does not obstruct view while operating, can properly adjust angles, facilitates a B ultrasonic screen to present all conditions in the uterine cavity, and ensures that a doctor can surveyably and pointedly apply an operation. The universal rotating part comprises a rotating part body, and is characterized in that two sides of the body are provided with a cervical clamp notch and a probe notch respectively.

The invention relates to a finely-adjustable nasogastric-feeding quantitative infusion device which comprises an injector with a piston rod and an infusion device. The injector is placed in a fixing groove of the infusion device, and a quantitative control device is arranged on a push rod of the infusion device. A quantitative adjustment device is arranged on one surface, facing towards a trigger, of a handle of the infusion device. The quantitative adjustment device comprises a wedge-shaped slider and a nut, the wedge-shaped slider is arranged on one surface, facing the trigger, of the handle, and the nut is arranged at the bottom of the handle and provided with a threaded rod in a penetrating manner, one end of the threaded rod is connected to the bottom of the wedge-shaped slider, and the threaded rod is rotated to enable the wedge-shaped slider to slide on the surface, facing the trigger, of the handle. The finely-adjustable nasogastric-feeding quantitative infusion device is simple in structure, convenient to use, capable of realizing finely-adjustable quantitative infusion and particularly suitable for home or homemade homogenate intestine and stomach tube feeding, filtration effect can be achieved, tube plugging is prevented, link pollution can be reduced, and opportunity of intestinal infections is prevented from increasing; the tail end is connected with an outer tube in a handle manner, so that a port is prevented from disconnection during operation, and the finely-adjustable nasogastric-feeding quantitative infusion device is clean, economical and convenient.

The invention discloses an entomogenous fungi pulvis for controlling pine greedy scale and a production method and usages thereof. The entomogenous fungi pulvis for controlling pine greedy scale is formed by adopting a strain of Pestalotiopsis olivacea to process a culture through primary solid strain culturing, secondary liquid culturing and third solid culturing. The production method thereof comprises the following steps of: 1) the primary solid strain culturing; 2) the secondary liquid culturing; 3) the third solid culturing; 4) naturally drying a semi-finished product in the shade until the water content rate is between 10 and 14 percent; 5) using a cracker to crack and requiring the grain diameters to be between 0.2 and 0.5cm; and 6) packaging. The entomogenous fungi pulvis for controlling pine greedy scale is mainly used for controlling pine greedy scale, and can also be used for controlling Oracella acuta and is suitable for both draught areas and humid areas.

The invention relates to a phlegm pumping pipe adapter having the switching function, which comprises a manifold, a switching module and a cover body. The manifold comprises a body and a pivot part. The body is composed of a base pipe and at least one take-over pipe. The base pipe is internally provided with an internal passage. The at least one take-over pipe is fixedly connected with the base pipe of the body. The at least one take-over pipe is provided with one through port. The through port is communicated with the internal passage. The pivot part is fixedly connected with the body to pass through one opening and connected with the internal space. The switching module is rotatably connected with the pivot part to comprise at least one communication pipe. The at least one take-over pipe is composed of one communication hole to be selectively communicated with the internal passage. The cover body is covered onto the pivot part.

Provided is a fixed-quantity infusion device for nasogastric tube feeding. The fixed-quantity infusion device comprises an injector and an infusion device body, wherein the injector is provided with a piston rod. The injector is placed in a fixed groove of the infusion device body, a fixed-quantity control device is arranged on a push rod of the infusion device body, and a fixed-quantity adjusting device composed of an L-shaped limiting hook and an L-shaped limiting rod or a fixed-quantity adjusting device composed of a wedge-shaped sliding block, a threaded rod and nuts is arranged on one face, facing towards a trigger, of a handle of the infusion device body. The simplified structure can be obtained by adding scales on the push rod and removing the fixed-quantity adjusting device. The fixed-quantity infusion device is simple in structure, convenient to use and especially suitable for nasogastric tube feeding at home or nasogastric tube feeding of self-made homogenate, and fixed-quantity infusion can be achieved; the fixed-quantity infusion device can play a filtration role, avoid pipe blockage, reduce link contamination and avoid the opportunity of increasing intestinal infection; the tail end of the infusion device is connected with an outer pipe through the handle, the phenomenon that a joint falls off in the process of operation can be avoided, and the fixed-quantity infusion device is clean, economical and convenient to use.
