Water bath heating type biological reagent reaction box

Abstract

The invention discloses a water bath heating type biological reagent reaction box. The water bath heating type biological reagent reaction box comprises a box body, a heating cylinder, a cover body, a carrying device and a motor; the carrying device is connected with the heating cylinder through a liquid discharging pipe; the liquid discharging pipe is connected with the upper portion of a right side plate of the box body through a backflow pipe; the carrying device comprises a conversion bin, an indwelling cylinder and a pump cylinder; a sliding seat is connected in the pump cylinder in a sliding manner; the inner cavity of the pump cylinder is communicated with the inner cavity of the cover body through a water inlet; a first one-way valve is arranged in the water inlet; the pump cylinder is communicated with the conversion bin through a water outlet; and a second one-way valve is arranged in the water outlet. In the use process of thewater bath heating type biological reagent reaction box of the invention,a reagent tube containing a biological reagent is inserted on a test tube rack, and then the box body is filled with water bath for heating, the water enters the cover body through a communicating hole; the carrying device is driven by a motor to work, so that the water is carried into the box body from the cover body, water circulation is achieved; and the water is heated when passing through the position of the heating cylinder, and water bath heating is more uniform and efficient.

Problems solved by technology

[0003] In the medical field, it is often necessary to make test specimens into biological reagents, and then react in the kit. Most biological reagents need to be reacted well under certain temperature conditions. For this reagent, it is necessary to For heating, the existing biological kits generally do not have the function of water bath heating, so a special water bath heating device is required for water bath heating

[0004] However, the water bath heating device in the prior art has the following disadvantages in the process of heating biological reagents: first, it can only heat a single test tube at a time, and in the medical field, the number of samples required every day is relatively large , so that the efficiency is low; second, in the process of heating the water area, the heated water remains in a static state, which leads to the uneven heating of the water bath, which affects the effect of the water bath heating and makes the reaction of biological reagents not good.
