Description

Technical Field

[0001] The present invention relates to the technical field of clinical medical microbiological inspection. Specifically, it relates to an agar pouring heat insulation and quantitative assistor for microorganism culture. Background Art

[0002] An agar plate is a covered petri dish made by adding sterilized culture medium and materials required for microorganism reproduction. Since it provides favorable conditions for microorganism reproduction, agar plates can be used to grow different microorganisms. Agar plates are particularly applied in industries such as industry, medical and health. Due to the overly high cost of commercial agar plates and problems such as too long preparation time of the used plates, they often cannot meet the actual requirements. Laboratories often make self-made agar plates by manual pouring.

[0003] The existing method usually pours the agar in a triangular flask into a petri dish according to experience. This method is difficult to ensure that the amount of agar poured into the petri dish is the same each time, which easily affects the experimental results and introduces operation errors. If a pipette or pipette tube is used to quantitatively aspirate and then pour the agar, it is easy to cause uneven distribution of the agar in the container as the temperature decreases during the pouring process of the agar plate, resulting in the problem of uneven nutrition among agar plates.

[0004] Therefore, there is an urgent need for an agar pouring heat insulation and quantitative assistor for microorganism culture to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an agar pouring heat insulation and quantitative assistor for microorganism culture, which has a simple structure and is easy to use, realizes rapid and quantitative pouring of agar, and reduces the operation burden of staff.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0027] Embodiment:

[0028] Please refer to Figures 1 - 3 , this embodiment provides an agar pouring heat insulation and quantitative assistor for microorganism culture, which includes a heating bottle 1. A clamping member is provided at the upper end of the heating bottle 1, and a pipetting mechanism is provided outside the heating bottle 1; a heat preservation mechanism is provided outside the pipetting mechanism. The pipetting mechanism includes a transmission tube 2, and the heat preservation mechanism is sleeved outside the transmission tube 2.

[0029] In the existing manual agar pouring method, quantitative pouring cannot be carried out, and there are manual operation errors; moreover, in batch pouring, the existing equipment cannot well solve the problem of uneven nutrition of agar as the temperature decreases. In the present invention, through the clamping member provided at the upper end of the heating bottle 1, the staff can fix an agar container such as an Erlenmeyer flask in the heating bottle 1 through the clamping member, and heat the Erlenmeyer flask by adding water to the heating bottle 1 and heating the heating bottle 1. The setting of the heating bottle 1 not only achieves the heating effect, but also can easily achieve the heat preservation effect of agar by controlling the temperature of the water in the heating bottle 1 after heating is completed. The transmission tube 2 of the pipetting mechanism realizes the extraction and transfer of agar, effectively avoiding problems such as easy scalding and difficult quantity control that are likely to occur when the staff pours. The heat preservation mechanism is sleeved outside the transmission tube 2, effectively avoiding the occurrence of sticking and uneven distribution caused by the rapid temperature loss of agar in the relatively thin transmission tube 2. The setting of the clamping member facilitates the staff to take and place the flask containing agar, which is easy to hold and not easy to scald. The heating bottle 1 is placed on a heating device for heating, and the heating bottle 1 can be made of a metal material; heating the Erlenmeyer flask by water bath effectively avoids the influence of the heating bottle 1 on the agar.

[0030] In some embodiments of the present invention, the transmission tube 2 is in an inverted "U" shape, and a first pumping and pressing mechanism 3 is connected to the top of the transmission tube 2. A three-way valve 4 is provided at the connection between the transmission tube 2 and the liquid storage tube. The first pumping and pressing mechanism 3 provided at the top of the inverted "U"-shaped transmission tube 2 enables the staff to draw agar from the flask into the liquid storage tube through the transmission tube 2. After drawing a certain amount, by controlling the three-way valve 4, the agar in the liquid storage tube is then discharged through the transmission tube 2 into a predetermined dish.

[0031] In some embodiments of the present invention, the heat preservation mechanism includes a pipe sleeve 5. A pumping port 6 is provided at the top of the pipe sleeve 5, and a second pumping mechanism 7 is connected to the pumping port 6; the inside of the pipe sleeve 5 is hollow, and a connecting pipe 8 communicating with the hollow part is provided on one side of the pipe sleeve 5; one end of the connecting pipe 8 is inside the heating flask 1. The staff can control the second pumping mechanism 7 to pump the water in the heating flask 1 into the pipe sleeve 5 through the connecting pipe 8, so that it can warm and keep the temperature of the pipe sleeve 5, and the agar will not be affected by rapid temperature loss when passing through the thinner transmission pipe 2.

[0032] It can be understood that both the first pumping mechanism 3 and the second pumping mechanism 7 can use a syringe to achieve the pumping effect. It is a common device, which is convenient for the staff to operate and can be quickly replaced, reducing the use cost.

[0033] In some embodiments of the present invention, a plurality of annular protrusions 9 are arranged vertically inside the pipe sleeve 5, and the annular protrusions 9 are made of rubber material. The annular protrusions 9 inside the pipe sleeve 5 can effectively limit and fix the transmission pipe 2, avoiding gaps between the pipe sleeve 5 and the transmission pipe 2; at the same time, the sealing layer formed between the plurality of annular protrusions 9 effectively increases the sealing effect and the heat preservation and heat transfer effect.

[0034] In some embodiments of the present invention, slots 10 are provided on both sides of the heating flask 1, and both the clamping member and the heat preservation mechanism are provided with plugs 11 adapted to the slots 10. The clamping member and the heat preservation mechanism can be quickly detachably installed through the cooperation of the plugs 11 and the slots 10, which is convenient for the staff to use, clean and store.

[0035] In some embodiments of the present invention, the pipe sleeve 5 is fixedly connected to the plug 11, and the connecting pipe 8 is arranged in an inverted "L" shape. The inverted "L"-shaped connecting pipe 8 pumps the water in the heating flask 1 into the pipe sleeve 5, relying on the atmospheric pressure to prevent the water from flowing back; at the same time, because the water level in the pipe sleeve 5 is higher than the water in the heating flask 1, the low-temperature water will drop into the heating flask 1 for reheating, effectively ensuring the temperature of the water in the pipe sleeve 5.

[0036] In some embodiments of the present invention, the clamping member includes a clamp 12 and a support rod 13. One end of the support rod 13 is connected to the clamp 12, and the other end of the support rod 13 is connected to the plug 11. The cooperation of the support rod 13 and the plug 11 facilitates the staff to fix the agar flask through the clamp 12 thereon before and after the pouring operation, and can perform quick operations without waiting due to the high temperature of the agar flask making it impossible to be taken. It can be understood that the clamp 12 can be selected with a common structure on the market to achieve stable clamping of the bottleneck of a conical flask.

[0037] In some embodiments of the present invention, a stopper is fixedly arranged on the transfer tube 2. The stopper is adapted to the Erlenmeyer flask and is fixed to the Erlenmeyer flask. Alternatively, a plug-in member 11 may be arranged on one side of the first suction and pressure mechanism 3, and it is fixed to the heating flask 1 by cooperating with the slot 10.

[0038] In some embodiments of the present invention, the first suction and pressure mechanism 3 includes a liquid storage cylinder 14. A vertical chute 15 is arranged inside the liquid storage cylinder 14. A sealing plate 16 is slidably connected to the vertical chute 15, and the side surface of the sealing plate 16 abuts against the inner wall of the liquid storage cylinder 14; a control rod 17 is connected above the sealing plate 16. A measuring scale is arranged outside the liquid storage cylinder 14, and the control rod 17 is an electric telescopic rod. The staff can control the up and down movement of the sealing plate 16 through the control rod 17, so as to form a negative pressure to suck the agar through the transfer tube 2. The setting of the measuring scale and the electric telescopic rod enables the staff to better quantitatively control the suction of the agar through the measuring scale and the telescopic rod; it can be understood that the liquid storage cylinder 14 can be made of a transparent material for the staff to observe.

[0039] In some embodiments of the present invention, a temperature sensor 18 is arranged inside the heating flask 1, and a display screen 19 is arranged outside the heating flask 1. The temperature sensor 18 is electrically connected to the display screen 19. The temperature sensor 18 arranged inside the heating flask 1 enables the staff to well observe and control its temperature to meet the experimental requirements.

[0040] In summary, the embodiments of the present invention provide an agar pouring heat insulation and quantitative assistor for microorganism culture, which includes a heating flask 1. A clamping member is arranged at the upper end of the heating flask 1, and a pipetting mechanism is arranged outside the heating flask 1; a heat preservation mechanism is arranged outside the pipetting mechanism. The pipetting mechanism includes a transfer tube 2, and the heat preservation mechanism is sleeved outside the transfer tube 2. Through the clamping member arranged at the upper end of the heating flask 1 in the present invention, the staff can fix an agar container such as an Erlenmeyer flask in the heating flask 1 through the clamping member, and heat the Erlenmeyer flask by adding water to the heating flask 1 and heating the heating flask 1. The setting of the heating flask 1 not only realizes the heating effect, but also can easily realize the heat preservation effect of the agar by controlling the temperature of the water in the heating flask 1 after the heating is completed. The transfer tube 2 of the pipetting mechanism realizes the extraction and transfer of the agar, effectively avoiding problems such as easy scalding and difficult quantity control that are prone to occur when the staff pours. The heat preservation mechanism is sleeved outside the transfer tube 2, effectively avoiding the situation of sticking and uneven distribution caused by the rapid temperature drop of the agar in the relatively thin transfer tube 2. The setting of the clamping member facilitates the staff to take and place the flask filled with agar, which is easy to handle and not easy to scald.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
