Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a mercury collection forceps. Background Art

[0002] A mercury thermometer is a type of expansion thermometer. The freezing point of mercury is -39°C, the boiling point is 356.7°C, and the temperature measurement range is -39°C to 357°C. It can only be used as an in-situ monitoring instrument. Using it to measure temperature is not only simple and intuitive, but also can avoid the errors of external remote thermometers.

[0003] The outer shell of a mercury thermometer is usually made of glass, which makes the mercury thermometer easy to break due to operating errors, resulting in mercury leakage. When users need to clean the broken glass debris, they also need to effectively collect the leaked mercury; after the mercury thermometer breaks, the scattered area is large, the particles are small, and they are mixed with the glass fragments, making the cleaning difficult.

[0004] Therefore, this application provides a mercury collection forceps to solve the cleaning problem after the existing mercury thermometer breaks. Content of the Utility Model

[0005] The utility model purpose of the present utility model is to overcome the defects described in the background art, thereby providing a mercury collection forceps.

[0006] To achieve the above purpose, the technical solution of the present utility model is:

[0007] Provide a mercury collection forceps, including a forceps main body, the forceps main body is composed of two clamping arms with an included angle, an extension arm extends from the end of each clamping arm, a clamping end is provided at the end of the extension arm, a groove is provided at the upper end of the forceps main body, and a collection bottle is installed in the groove; a suction pipe is penetrated through the clamping arm and the extension arm, one end of the suction pipe is flush with the end of the clamping end and is provided with a suction cup port, the other end of the suction pipe extends into the collection bottle in the groove, and an air bag is provided at the upper end of the collection bottle.

[0008] Furthermore, slideway grooves extending along the length direction of the clamping arm are symmetrically opened on both side walls of the clamping arm, and sliders are slidably installed on the slideway grooves; an installation shaft is provided at the lower end of the slider, a spring is sleeved on the installation shaft, and the installation shaft and the spring are slidably installed in the slideway groove; an L-shaped baffle extends fixedly from the upper end of the slider, and the short end of the L-shaped baffle contacts and presses against the air bag.

[0009] When the mercury collection forceps of the present utility model are in use, hold the two clamping arms by hand and press the slider downward with the thumb. At this time, the short end of the L-shaped baffle squeezes the airbag; pick up and collect the broken glass debris of the thermometer; at the same time, slowly release the thumb, and under the action of the spring, the slider drives the L-shaped baffle to move upward, the airbag restores its deformation, and an adsorption effect is formed at the suction cup opening, sucking the mercury into the collection bottle through the suction pipe; while continuously collecting the glass debris, the mercury can be collected into the collection bottle, or the glass can be collected or the mercury can be collected separately, improving the collection efficiency after the mercury thermometer is broken.

[0010] Further, a bottle insertion port is provided in the groove, and the collection bottle and the bottle insertion port are movably and hermetically inserted. This setting facilitates timely replacement of the collection bottle, prevents mercury volatilization, and performs centralized treatment after timely sealing.

[0011] Further, the suction cup opening is made of silica gel material, and the opening is in the shape of a flat flared mouth; this setting can increase the adsorption area of the suction cup opening.

[0012] Preferably, a concave pinch point is provided in the middle of the slider to prevent the finger from slipping off the slider and affecting the adsorption effect.

[0013] Preferably, sulfur powder is contained in the collection bottle. With this setting, when the mercury is sucked into the bottle, it reacts with the sulfur powder to form mercury sulfide, reducing the volatilization toxicity. The tube head of the suction pipe in the collection bottle is at least one-third of the height of the bottle body above the bottle mouth, preventing the substances in the bottle from flowing back when continuously sucking mercury.

[0014] Preferably, the clamping ends are symmetrically arranged on the inner sides of the ends of the two extension arms and form an acute angle inclined upward with the inner sides of the extension arms. With this setting, when picking up the glass debris of the thermometer, it is not easy to slip off.

[0015] The beneficial points of the present utility model are as follows:

[0016] 1. The slider that can slide up and down on the clamping wall drives the L-shaped baffle to compress the airbag, completing the suction of mercury into the collection bottle by the suction cup head and the suction pipe. While cleaning the glass debris, the scattered mercury is collected, solving the problem that after the mercury thermometer is broken, the scattered area is large, the particles are small, and it is mixed with the glass fragments, making it difficult to clean.

[0017] 2. The sulfur powder provided in the bottle reacts with the collected mercury to form mercury sulfide, reducing the harm caused by mercury volatilization. Moreover, the collection bottle and the forceps are separately arranged, facilitating timely treatment of the collected mercury and further reducing the harm of mercury volatilization.
