Since one side of the first bevel gear is meshed with the second bevel gear, the transmission rod inside the second bevel gear will carry multiple groups of stirring rods to evenly mix the powder and liquid, thereby ensuring the comfort of drug administration for critically ill patients.

[0019] By setting up a heating mechanism, after the medicine liquid is mixed, the medical staff starts the control valve so that the medicine liquid can flow along the first connecting tube with the guidance of the water pump and the second connecting tube to reach the gastric tube for drug administration. According to the patient's optimal eating temperature, the medical staff can start the heating wire to heat the thermal pad to a suitable temperature, thereby heating and raising the temperature of the medicine liquid passing through the first connecting tube. It is portable and practical.

[0020] By providing the disassembly and assembly mechanism, when the gastric tube needs to be replaced, the medical staff can hold the screw-mounted barrel at one end of the gastric tube and twist it to disengage it from the installation screw sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The grinding and mixing mechanism 4 includes an operation area 41, and the operation area 41 communicates with the end of the feeding guide 3. Inside the operation area 41, a first linkage component 42 is installed.

At one end of the two crushing rollers 421, gears 422 are fixed, and at the same end of the two crushing rollers 421, first synchronous wheels 423 are fixed.

[0037] A motor 424 is installed at the end of one of the crushing rollers 421. A first synchronous belt 425 is sleeved around the peripheries of the two first synchronous wheels 423, and on the inner sides of the other ends of the two first synchronous belts 425, a second synchronous wheel 426 is meshed. Grinding rollers 427 are fixed around the peripheries of the two first rotating rods 43. The gears 422 and the grinding rollers 427 are respectively arranged in the lower area inside the operation area 41, and the gears 422 and the grinding rollers 427 are symmetrically distributed along the vertical central axis of the operation area 41. And a first rotating rod 43 is fixed inside the second synchronous wheel 426. A second linkage component 44 is installed inside the mixing area 5. The second linkage component 44 includes a third synchronous wheel 441, and the third synchronous wheel 441 is fixed at one end of one of the first rotating rods 43. A second synchronous belt 442 is sleeved around the periphery of the third synchronous wheel 441, and on the inner side of the other end of the second synchronous belt 442, a fourth synchronous wheel 443 is sleeved. A second rotating rod 444 is fixed in the middle of the fourth synchronous wheel 443, and first bevel gears 445 are distributed around the periphery of the second rotating rod 444. On one side of the multiple first bevel gears 445, second bevel gears 446 are meshed, and a transmission rod 447 is fixed in the middle of the multiple second bevel gears 446. Stirring rods 448 are distributed on both sides of the multiple transmission rods 447, and the stirring rods 448 are equidistantly distributed along both sides of the multiple transmission rods 447.

[0038] A filter assembly 45 is installed below the interior of the operation area 41. The filter assembly 45 includes a slide rail groove 451, and the slide rail groove 451 is opened on both sides below the interior of the operation area 41. A filter plate 452 is movably arranged inside the slide rail groove 451. The medical staff pre-activates the motor 424 to rotate one of the crushing rollers 421 in the operation area 41. Since gears 422 are provided on the peripheries of the same ends of the two crushing rollers 421 and are engaged with each other, the two crushing rollers 421 can rotate in opposite directions. Subsequently, the medical staff opens the feeding cover 2 and inputs the medicine from the feeding guide 3, so that one set of crushing rollers 421 can perform the crushing operation on the medicine. And since a first synchronous pulley 423 is fixed on the periphery of the same end of the crushing roller 421, under the meshing drive of the two first synchronous belts 425, the two second synchronous pulleys 426 and the grinding rollers 427 around the first rotating rod 43 can be driven to rotate synchronously and in alignment, so as to achieve the operations of synchronous crushing and grinding.

[0039] Among them, the qualified ground medicine powder will pass through the filter plate 452 and enter the mixing area 5 by filtration, and the unqualified medicine blocks, etc. will be intercepted by the filter plate 452. Subsequently, the medical staff can use the slide rail groove 451 to extract it from the operation area 41 for processing. Next, the medical staff can add liquid through the feeding guide 3, and the liquid will pass through the operation area 41 and enter the mixing area 5. Since third synchronous pulleys 441 and fourth synchronous pulleys 443 are respectively arranged on the peripheries of one ends of the first rotating rod 43 and the second rotating rod 444 arranged inside the mixing area 5, and a second synchronous belt 442 is sleeved between the two synchronous pulleys, the second rotating rod 444 can drive the first bevel gears 445 distributed around it to rotate. Since the first bevel gear 445 is engaged with the second bevel gear 446 on one side, the transmission rod 447 inside the second bevel gear 446 will drive multiple groups of stirring rods 448 to uniformly mix the medicine powder and the liquid, so as to ensure the comfort of drug administration for critically ill patients.

[0040] As Figures 2 to 5 shown, the heating mechanism 9 includes a sleeve 91, and the sleeve 91 is sleeved on the periphery of one side of the first connecting pipe 6. A heating wire 92 is arranged inside the sleeve 91, and a heat conducting pad 93 is attached to the inner side of the sleeve 91. The inner size of the sleeve 91 matches the outer size of the heat conducting pad 93. After the liquid medicine is mixed, the medical staff activates the control valve 11 so that the liquid medicine can flow along the first connecting pipe 6 under the guidance of the water pump 7 and be drained through the second connecting pipe 8 to perform the drug administration operation on the gastric tube 103. For the optimal feeding temperature of the patient, the medical staff can activate the heating wire 92 to heat the heat conducting pad 93 to a suitable temperature, so as to heat and raise the temperature of the liquid medicine passing through the first connecting pipe 6, which is portable and practical.

[0041] Secondly, the disassembly and assembly mechanism 10 includes a mounting screw sleeve 101, and the mounting screw sleeve 101 is fixedly arranged on one side of the main body 1, a screw barrel 102 is screwed inside the mounting screw sleeve 101, and the end of the screw barrel 102 is connected with a gastric tube 103, and the middle part of the mounting screw sleeve 101 is connected with the second connecting tube 8.

[0042] The working principle of the technical solution provided by the utility model is as follows:

[0043] The medical staff starts the motor 424 to drive the crushing roller 421 in the working area 41 to rotate. The two crushing rollers 421 rotate towards each other due to the meshing of the gears 422 at the same end. Then, the feed cover 2 is opened and the medicine is put into the feed guide 3. The crushing roller 421 crushes the medicine. The first synchronous wheel 423 provided around the same end of the crushing roller 421, under the meshing transmission of the two first synchronous belts 425, drives the two second synchronous wheels 426 and the grinding roller 427 around the first rotating rod 43 to rotate synchronously, thereby achieving synchronous crushing and grinding operations.

[0044] Among them, the qualified ground medicine powder is filtered through the filter plate 452 and enters the mixing area 5, and the unqualified medicine blocks will be intercepted by the filter plate 452. The subsequent medical staff will use the slide groove 451 to extract them from the working area 41 for processing.

[0045] Afterwards, the medical staff adds liquid through the feed guide 3, and the liquid enters the mixing area 5 through the working area 41. Since the third synchronous wheel 441 and the fourth synchronous wheel 443 are respectively arranged around one end of the first rotating rod 43 and the second rotating rod 444 arranged inside the mixing area 5, and the second synchronous belt 442 is sleeved between the two synchronous wheels, the second rotating rod 444 can rotate with the first bevel gear 445 distributed around it. Since one side of the first bevel gear 445 is engaged with the second bevel gear 446, the transmission rod 447 inside the second bevel gear 446 will bring multiple sets of stirring rods 448 to evenly mix the powder and liquid, thereby ensuring the comfort of medication for critically ill patients.

[0046] Finally, after the medicine liquid is mixed, the medical staff starts the control valve 11 to allow the medicine liquid to flow along the first connecting tube 6 with the guidance of the water pump 7 and the second connecting tube 8 to reach the gastric tube 103 for drug administration. According to the patient's optimal eating temperature, the medical staff can start the heating wire 92 to heat the thermal pad 93 to a suitable temperature, thereby heating and heating the medicine liquid passing through the first connecting tube 6. It is portable and practical. Finally, when the gastric tube 103 needs to be replaced, the medical staff can hold the screw barrel 102 at one end of the gastric tube 103 and twist it to disengage it from the mounting screw sleeve 101.
