The utility model is characterized in that a cage is arranged in the container body, and the upper part of the container body is provided with a container lid. A filter, a one-way valve, a pressure meter, a safety valve, an emptying valve and a control valve are arranged on the container lid. The spray head is connected with the control valve, and the pressurizer is connected with the filter through a rubber sheet flexible pipe. The utility model has the advantages of accuracy, high efficiency, convenient operation, low cost, etc. Under an endoscope, the needed cleaning solution, staining solution, hemostasis physic liquor, etc., are evenly sprayed to the needed area through a conical surface with a larger angle after atomized through a miniature spray head.

Description

The digestive endoscopy high-pressure sprayer

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of digestive endoscopy high-pressure sprayer.

In digestive endoscopy diagnosis and treatment process, often, intracavity mucus influences treatment effect because of hiding the visual field.The sweep-out method that adopts is from the endoscope movable detecting hole injecting normal saline with syringe at present, because the syringe pondage is few, pressure is less during injection, so range is short, directivity is poor, and the persistent period deficiency makes cleaning effect dissatisfied, and waste time and energy, also have the problems referred to above in the mucosa pigment dyeing inspection of diagnosing tumor in early days.In addition, when digestive tract hemorrhage carries out the treatment of scope lower hemostasia herbal sprinkling, also because of the sprinkling process can't continue to carry out, spray direction and be difficult to control, and make hemostatic healing efficacy not high, drug waste is bigger.

The purpose of this utility model provides a kind of by the high-pressure mini atomizing required cleaning solution, dye liquor, hemostasis medicinal liquid etc. evenly being sprayed onto under scope need regional digestive endoscopy high-pressure sprayer.

This utility model comprises container body, prelum, fog-spray nozzle, be characterized in: be provided with retainer in the container body, top is provided with container cover, container cover is provided with filter, check valve, Pressure gauge, relief valve, exhaust-valve, control valve, fog-spray nozzle is connected on the control valve, prelum by hose connection on filter.Control valve comprises valve body, valve handle, and valve handle is on container cover, and valve body is provided with several interfaces on valve body under container cover, and valve handle one end is the syringe needle shape.Retainer is the shelf that several cavitys are arranged, and cavity is built-in with inner bag, is equipped with siphon in the inner bag, and the siphonal other end is connected with interface on the valve body.Fog-spray nozzle comprises connection tube, hand-operated valve, conduit, shower nozzle, and an end of connection tube is connected with control valve, and the other end is connected with hand-operated valve, and an end of conduit connects hand-operated valve, and the other end connects shower nozzle.

The utlity model has accurate, efficient, easy operating, advantage such as with low cost, and under scope, atomizings such as required cleaning solution, dye liquor, hemostasis medicinal liquid back evenly is sprayed onto the zone that needs with a taper surface than wide-angle by miniature atomizer.

The utility model is described in further detail below in conjunction with accompanying drawing

In Fig. 1,2,3: aerosol apparatus comprises container body, prelum, fog-spray nozzle.Container body 14 inner chambers are provided with a retainer 17, and retainer 17 is for there being the shelf of several cavitys.Be built-in with inner bag 18 at each cavity, fill different liquid respectively in each inner bag 18, and be equipped with siphon 19 in inner bag 18, the other end of siphon 19 is connected with interface 16 on the valve body 15.The container that container body 14 adopts aluminium alloy to make, the lower surface of the upper surface of container body 14 and container cover 3 is all opened double flute and is matched.O RunddichtringO 13 is housed in the groove, and its periphery all compresses with the fast screw 2 of pressing, and makes container body 14 become a sealed container, is mainly used to pressure-bearing and pressurize.

Container cover 3 is provided with filter 4, check valve 5, Pressure gauge 6, relief valve 7, exhaust-valve 22, control valve 8.Check valve 5 is a standard component, can guarantee gas unidirectional inflation in pressure vessel.The upper end of check valve 5 is connected with filter 4, and the other end of filter 4 is connected with prelum 1 with flexible pipe, and prelum 1 can be an inflator, and foot-operated or inflation skin is assisted or electronic force (forcing) pump.Pressure gauge 6 is a reading instument; can read the force value in the container easily; relief valve 7 is a safety guard; when the pressure in the container reaches the setup pressure value of relief valve 7; relief valve 7 can be opened the unnecessary gas of draining automatically; guaranteeing that container is in a safe condition, when this valve is set will with Pressure gauge 6 supporting uses.Exhaust-valve 22 is hand-operated valves, and the pressure in needs are drained container or when need changing liquid in the inner bag 18 must be opened exhaust-valve 22 earlier, and the pointer of observing Pressure gauge 6 again just can be opened container cover 3 when zero-bit.Control valve 8 comprises valve body 15, valve handle 20, and valve handle 20 is on container cover, and valve body 15 is provided with several interfaces 16 and is connected with siphon 19 under container cover on valve body 15.Valve handle one end is a syringe needle shape 21, and effect is the position of interface 16 on the indication valve body 15.

Fog-spray nozzle comprises connection tube 9, hand control valve 10, conduit 11, shower nozzle 12, connection tube 9 adopts High strength plastic pipe, endoporus is the passage of liquid, tube wall can pressure-bearing, one end of connection tube 9 is connected with control valve 8, and the other end is connected with hand control valve 10, and an end of conduit 11 connects hand control valve 10, the other end connects shower nozzle 12, shower nozzle 12 ejection band press liquids.

The working procedure of digestive endoscopy high-pressure sprayer is such: the liquid of packing in inner bag 18 earlier, again inner bag 18 is arranged in the cavity of retainer 17, covered container lid 3, cover at lid container and siphon 19 to be inserted in the liquid in 3 o'clock, pressurize in container body 14 by prelum 1 then, at this moment to observe manometric value, make institute's plus-pressure reach required value.Shower nozzle 12 and conduit 11 are inserted into desired location from endoscope movable detecting hole, rotate valve handle 20 again and valve handle one end syringe needle shape 21 is pushed the position of required liquid outlet, after putting in place, whole operation presses hand control valve 10, injection beginning, under the direct-view of gastroscope, can determine emitted dose and time according to practical situation.If spray another kind of liquid, only need to rotate valve handle 20, the position that an end 21 is pushed the liquid outlet of another kind of liquid gets final product.
