Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

Example 1

Fig. 1 shows the structure of the present embodiment. A simple pill dripping device for a laboratory comprises a water tank 1, an iron stand 5, an injection pump 4, a pill dripping device, a needle 12 and a condensation pipe 8. The bottom of the water tank 1 is provided with a grinding hole 3. The pill dropping device is an injector 2 and comprises a nipple, an empty barrel and a piston 21. The nipple end of the injector penetrates out of the ground hole 3 at the bottom of the water tank and is connected with the ground of the ground hole 3 for sealing; the piston 21 of the syringe 2 is connected to the syringe pump 4, and the syringe pump 4 is fixed to the iron stand 5. The nipple of the syringe 2 is connected to one end of a needle 12, the other end of the needle 12 is connected to the condensation duct 8, the needle 12 is an elongated tube, and the inner diameter of the condensation duct 8 is larger than the outer diameter of the needle. The end of the condensation pipe 8 is provided with a filter screen 10 and a plug 11 in sequence so as to separate and collect the dripping pills and the condensate. The water tank 1 is a constant temperature water tank having a constant temperature 6 and a temperature probe 7 to control the water temperature. The injector, the needle head and the condenser tube are all made of transparent materials. The condenser pipe is filled with condensate, which can be oil-based or water-based condensate. The oily condensate comprises dimethyl silicone oil, liquid paraffin, methyl silicone oil vegetable oil and liquid paraffin; the aqueous condensate comprises water, an alcohol solution and a dilute acid solution. In this embodiment, the density of the condensate 9 in the condensation duct 8 is less than the density of the dropping pill.

Example 2

Fig. 2 shows the structure of the present embodiment. The main structure of this embodiment is substantially the same as that of embodiment 1, except that: the needle head 12 of this embodiment is a curved needle, the end of which is connected to the lower end of the condensation duct 8. The density of the condensate in the condensation pipe 8 is larger than that of the dripping pills, and the dripping pills are lifted to the upper end of the condensation pipe through the condensation pipe 8 after coming out of the needle head.

The using method comprises the following steps:

before use, prepared liquid medicine is sucked into the injector 2, then the injector 2 is connected and fixed with the ground hole 3, water is injected into the water tank 1, the power supply of the thermostat 6 is connected, and the temperature is adjusted to the required liquid medicine heat preservation temperature. Refrigerating the condensate 9 in a refrigerator at about 4 deg.C for 24h, pouring the condensate 9 into a condenser tube 8 before use, and using the device of example 1 if the density of the dripping pill is higher than that of the condensate, or using the device of example 2.
