As shown in fig. 1-5, a rectal administration device for internal medicine, including being injection tube 1 of straight tube type, the both ends of injection tube 1 are fixed respectively to be communicated with female adapter tube 2 and drain pipe 3, the inside threaded connection of female adapter tube 2 has one end to extend to push rod 4 inside injection tube 1, push rod 4 is located the inside one end of injection tube 1 and rotates and is connected with the piston block 5 that closely pastes and be in sliding fit with injection tube 1 inner wall, drain pipe 3 intercommunication of injection tube 1 has the subassembly of dosing that can only go out liquid, the external surface fixed intercommunication of injection tube 1 has the feed liquor subassembly that can only feed liquor.

In this embodiment, the injection tube 1 is used for storing liquid medicine, the administration component can only discharge liquid, and the liquid inlet component can only feed liquid; the existing injector directly pushes the push rod 4 to move manually, so that the phenomenon that the push rod 4 is touched too violently or carelessly to move the piston block 5 is easy to occur, the injection flow rate of liquid medicine is too violent, the discomfort of a patient is caused, the anus is retracted, and the administration work is influenced, but the utility model adopts a rotary linear pushing mode, the piston block 5 is pushed to move only by driving the push rod 4 to rotate, the slow rotation can be realized, and the piston block 5 cannot be driven to move by applying a pushing force to the push rod 4, so the risk can be greatly avoided, and the administration work is facilitated; considering the variety of dosing, the utility model discloses a cooperation of subassembly and feed liquor subassembly of dosing can realize the interpolation of medicine and dose, consequently does not need the cooperation of a plurality of syringes, can reduce the consumption of consumptive material.

Specifically, a spherical cavity 6 is formed in one end, located inside the injection tube 1, of the push rod 4, a spherical block 7 is fixed to one end, located near the push rod 4, of the piston block 5, and the spherical block 7 is located inside the spherical cavity 6 and forms a gap with the spherical cavity 6.

In this embodiment, the push rod 4 needs to rotate to realize the movement, but the piston block 5 needs to keep a linear movement characteristic, so the connection between the push rod 4 and the piston block 5 is a rotational connection, the utility model discloses in adopt the spherical cavity 6 to cooperate with the spherical block 7 mode to realize the rotational connection between the two, it is also possible to realize the above-mentioned function through the bearing or other structural modes equally; in the process of rotating the push rod 4, the push rod 4 can rotate around the spherical block 7 through the spherical cavity 6, the push rod 4 can provide a force for the piston block 5 to drive the piston block 5 to move, the rotating directions of the push rod 4 are different, the moving direction of the piston block 5 can also change, and the pumping and extruding work is finished; it should be noted that more than half of the volume of the spherical block 7 is located in the spherical cavity 6, so that a limit structure is formed between the spherical block 7 and the spherical cavity 6.

Specifically, the subassembly of dosing includes the connector 8 with drain pipe 3 intercommunication, and the inside of connector 8 is provided with the check valve, and the one end of connector 8 is fixed with the intercommunication and has hose 9, and the fixed intercommunication of the one end that connector 8 was kept away from to hose 9 has injector head 10.

In this embodiment, because the design of check valve, when push rod 4 drove the liquid medicine extrusion of piston block 5 in with injection pipe 1, the check valve was in the open mode, and the liquid medicine enters into hose 9 through connector 8 in, then the liquid medicine enters into injection head 10 through hose 9 in, and the liquid medicine directly spouts through injection head 10, and wherein injection head 10 and hose 9 partly need fill in into the intestines through the anus.

Specifically, one end of the hose 9, which is far away from the connector 8, is fixed with a rubber head 11 which is sleeved outside the injector head 10, and the outer surface of the rubber head 11 is provided with a through hole 12.

In this embodiment, the phenomenon that the micropore on the injection head 10 is stopped up is existed to injection head 10 direct and patient internal contact, and through the design that increases rubber head 11, rubber head 11 is direct and patient contact, and rubber head 11 does not influence the normal work of injection head 10 after receiving extrusion deformation, consequently can guarantee the normal injection of liquid medicine, and wherein the head, the afterbody and the middle section of rubber head 11 all are provided with through-hole 12.

Specifically, the ejection head 10 and the rubber head 11 are each spherical.

In this embodiment, the spray head 10 and the rubber head 11 having a spherical structure are not provided with corners, and thus can be easily inserted into the body.

Specifically, the liquid inlet assembly comprises a liquid inlet pipe 13 fixedly communicated with the injection pipe 1, and a one-way valve is arranged inside the liquid inlet pipe 13.

In this embodiment, the principle of feed liquor subassembly and play liquid subassembly is the same, all realizes the interpolation of liquid medicine through the check valve, when piston block 5 moved towards the direction of keeping away from play liquid subassembly under push rod 4 drives, the check valve on the play liquid subassembly was in the closed condition this moment, therefore the liquid medicine can only enter into injection pipe 1 through feed liquor pipe 13 in, when the inside liquid medicine of injection pipe 1 was discharged to the needs, because the existence of check valve, the liquid medicine can only discharge through hose 9.
