The working principle and the advantages of the invention are as follows: when utilizing this kind of severe medical science branch of academic or vocational study clinical treatment to feed medicine to the disease with traditional chinese medicine feed ware, the course of work is as follows:

assembling a medicine feeder: as shown in fig. 1 and 3, the screw cap 17 is screwed on the lower end of the medicine injection cylinder 1, the negative pressure box 18 is screwed on the third annular flange 39, the third threaded sleeve 44 is screwed on the third cylindrical sleeve 42, and the second threaded sleeve 43 is screwed on the second cylindrical sleeve 40, as shown in fig. 2, the flange cover 30 and the filter cylinder 36 are installed on the filter residue cylinder 37, the first threaded sleeve 33 is screwed on the first cylindrical sleeve 31, and the traditional Chinese medicine medicament is poured into the medicine storage cylinder;

air exhaust: after the installation process is completed, the pressure rod 9 and the medicine injection barrel 1 are held by hands, and the pressure-loosening-pressure rod 9 is continuously pressed for multiple times, so that the pressure rod 9 drives the rack 2 to move in a reciprocating mode on the medicine injection barrel 1 under the matching use of the spring 8 by utilizing the lever action, the rack 2 drives the spiral blade shaft 16 to rotate unidirectionally through the ratchet wheel 25, and further the air in the space below the partition plate 14 inside the medicine injection barrel 1 is discharged through the plastic bent pipe 21, therefore, on one hand, whether the medicine feeder is normally used or not can be checked before medicine feeding, and on the other hand, excessive air is prevented from being conveyed to the patient body to cause flatulence.

Inserting a tube: after the emptying operation is finished, the plastic bent pipe 21 is inserted into the esophagus of the patient from the mouth of the patient softly, and then the adsorption gasket 19 is coated and attached to the skin around the mouth of the patient and smoothed so as to keep the adsorption gasket 19 attached to the skin well;

pumping medicine: according to the emptying step, the pressure rod 9 is slowly and uniformly pressed, loosened and pressed, so that the traditional Chinese medicine in the medicine injection cylinder 1 and positioned in the lower space of the partition plate 14 is conveyed into the body of a patient by the spiral blade shaft 16 through the plastic bent pipe 21, the first liquid pipe 15 is utilized to generate suction force in the residue filtering cylinder 37, the suction force sucks the traditional Chinese medicine in the medicine storage cylinder into the filter cylinder 36 through the second liquid pipe 32, fine medicine residues in the traditional Chinese medicine are filtered out through the filter cylinder 36, the medicine residues are filtered out while feeding the medicine, the treatment time of the traditional Chinese medicine is saved, time and labor are saved, and discomfort caused by the fact that the medicine residues enter the body of the patient is avoided;

as shown in fig. 2, when the rack 2 drives the outer ring of the ratchet 25 to rotate, the outer ring drives the first shaft lever 28 to rotate through the gear ring 26 and the gear 27, so that the first shaft lever 28 drives the brush bar 29 to clean the inner wall of the filter cartridge 36, and residue adhered to the inner wall of the filter cartridge 36 is brushed away, so that the efficient filtering effect and the passing performance of the filter cartridge 36 are ensured, and the phenomenon that the passing performance of the filter cartridge is reduced due to excessive adhesion of the residue to cause the blocking of medicine feeding is avoided;

as mentioned above, in the process of the rack 2 reciprocating motion, the piston plate 13 is synchronously driven to reciprocate in the pump cylinder 24, as shown in fig. 1 and fig. 3, so that the piston plate 13 alternately applies suction force and compression force to the pump cylinder 24, when the suction force is generated in the pump cylinder 24, because the conduction direction of the check valve one 11 points to the air pipe one 10, and the conduction direction of the check valve two 12 points to the inside of the pump cylinder 24, the suction force pumps the air in the negative pressure box 18 into the pump cylinder 24 through the air pipe one 10 and the air pipe two 35, so that the negative pressure box 18 forms a low pressure state, when the compression force is generated in the pump cylinder 24, the compression force exhausts the air in the pump cylinder 24 through the check valve two 12, so as to realize the evacuation of the negative pressure box 18, after the low pressure state is formed in the negative pressure box 18, the air in the groove 20 is pumped through the air pipe three 45 under the action of pressure difference, thereby utilizing the external air pressure to attach the adsorption gasket 19 to the skin of the mouth of the patient more tightly, improving the sealing performance, avoiding the oral liquid and the liquid medicine from overflowing from the mouth, and the overflowed oral liquid and the liquid medicine are sucked into the negative pressure box 18 through the groove 20 and the air pipe III 45 under the action of pressure difference to be collected, thereby being convenient for collecting the oral liquid and the liquid medicine, saving time and labor, improving the nursing efficiency of the patient, reducing the labor intensity of nursing personnel, being also beneficial to maintaining the sanitary environment around the mouth of the patient and at the lying position, wherein the pressure release valve 46 plays a role of maintaining the air pressure in the negative pressure box 18, avoiding the continuous reduction of the air pressure in the negative pressure box 18, causing the movement obstruction of the piston plate 13 in the pump cylinder 24, further influencing the medicine feeding, and also preventing the stimulation discomfort caused by the too low air pressure in the groove 20 to the skin, after the air pressure in the negative pressure box 18 is lower than the set value of the pressure release valve 46, the relief valve 46 opens to allow outside air into the negative pressure cartridge 18, thereby maintaining the negative pressure cartridge 18 in a stable low pressure state.

Tube drawing and disassembling: after the medicine feeding is finished, the medicine feeding reaction of a patient is observed for a period of time, then the third screw sleeve 44 is detached from the third cylinder 42, so that the pressure in the groove 20 is relieved, the adsorption gasket 19 is separated from the skin, then the plastic elbow 21 is pulled out gently, and then the screw cap 17, the negative pressure box 18, the flange cover 30 and the filter cylinder 36 are detached so as to carry out corresponding medical treatment respectively.

The whole process is convenient and fast to operate, practical and convenient, reduces the labor intensity of medical care, and is safe and sanitary.
