Description

Technical Field

[0001] The utility model relates to the field of medical equipment for nursing critically ill patients, in particular to a medicine feeding device for critically ill patients. Background Art

[0002] Since critically ill patients are too ill to take medicine by themselves, they need to be fed by medical staff. At present, liquid medicines are fed with a cup or spoon, and the liquid medicine can easily flow out from the corners of the patient's mouth, contaminating clothes and bedding, and it is easy to choke if the patient does not cooperate well. Solid medicines are generally crushed into powder using a device, dissolved in liquid medicine or pure water, and fed to the patient together; a common feeding device currently uses a syringe and a hose, where the liquid medicine is placed in the syringe, one end of the hose is connected to the syringe, and the other end is placed in the patient's esophagus and pharynx, and the medicine is injected into the patient's esophagus through the syringe. However, the hose is long, and after the feeding is completed, more medicine remains on the inner wall of the hose, resulting in the quantitative medicine not being completely fed to the patient, which undoubtedly reduces the efficacy of the medicine.

[0003] In view of the above problems, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] like Figure 1-4 As shown, a medicine feeding device for critically ill patients comprises a medicine cartridge 1, a cartridge cover 2, a syringe 3 and a push plate 4. The cartridge cover 2 is threadedly connected to the wide mouth of the medicine cartridge 1, the outlet of the syringe 3 is connected to an air pipe 31, a port 21 penetrating the cartridge cover 2 is provided at the center of the cartridge cover 2, a section of the air pipe 31 away from the syringe 3 is movably connected to the port 21, that is, the syringe 3 can inject air into the medicine cartridge 1 through the cartridge cover 2;

[0025] The side of the push plate 4 fits the inner wall of the cartridge 1, and the side of the push plate 4 is slidably connected to the inner wall of the cartridge 1. The push plate 4 moves forward in the cartridge 1 to squeeze the liquid medicine in the cartridge 1 forward. The back of the push plate 4 is provided with a protrusion 45. The shape and size of the protrusion 45 are adapted to the front end of the cartridge 1. The protrusion 45 can squeeze out the liquid medicine remaining on the inner wall of the front end of the cartridge 1.

[0026] A ventilation short tube 43 penetrating the push plate 4 is provided at an eccentric position on the front side of the push plate 4, the mouth of the ventilation short tube 43 is threadedly connected with a first tube cover 44, and the outlet of the cartridge 1 is threadedly connected with a second tube cover 13. When the liquid medicine is put into the cartridge 1, the push plate 4 can be just at the liquid level of the liquid medicine.

[0027] A one-way valve 22 communicating with the interior of the cylinder cover 2 is arranged on the side of the cylinder cover 2 , and a protruding handle 42 is arranged at the central position of the front of the push plate 4 , and the handle 42 is convenient for taking out the push plate 4 .

[0028] Four to eight sliders 41 are evenly and evenly arranged on the surface of the push plate 4, and the four to eight sliders 41 are distributed around the surface of the push plate 4. Four to eight slide grooves 11 are evenly and evenly arranged on the inner wall of the cartridge 1, and the four to eight slide grooves 11 are distributed around the inner wall of the cartridge 1. The slide groove 11 is parallel to the length direction of the cartridge 1. The slider 41 is slidably installed in the slide groove 11. The slider 41 slides in the slide groove 11, which guides the push plate 4 and makes the movement of the push plate 4 more stable.

[0029] The surface of the cartridge 1 is provided with a plurality of protrusions 12 at equal intervals along its latitude and longitude directions. The protrusions 12 are hemispherical, and the circumferential surfaces of the protrusions 12 are fixed to the surface of the cartridge 1. The protrusions 12 are made of soft rubber or soft silicone. When the cartridge 1 is placed in the mouth of a critically ill patient, the protrusions 12 can enhance friction so that the cartridge 1 will not move.

[0030] The two ends of the air tube 31 are respectively connected to the syringe 3 and the interface 21 by threads, and the air tube 31 has good sealing performance at the connection position.

[0031] The front end of the cartridge 1 is gradually narrowed.

[0032] The projection 45 is gradually narrowed.

[0033] In summary: first, place the cartridge 1 vertically with the large mouth of the cartridge 1 facing upwards, put the prepared liquid medicine into the cartridge 1, and then put the push plate 4 into the cartridge. Because the short vent tube 43 can be ventilated, the push plate 4 can move downward until it just fits the liquid surface of the medicine. At this time, screw the first tube cover 44;

[0034] Install the cartridge cover 2 at the wide mouth of the cartridge 1, connect the air tube 31 to the interface 21 and the syringe 3, then lay the cartridge 1 flat or upside down, unscrew the second cartridge cover 13, and insert the cartridge 1 into the patient's mouth so that the outlet of the cartridge 1 faces the patient's throat;

[0035] The syringe 3 is pushed, and the air in the syringe 3 enters the cartridge 1 through the air tube 31. At this time, the air is located between the push plate 4 and the cartridge cover 2. As the syringe 3 is pushed forward, the air can push the push plate 4 forward, and the push plate 4 will squeeze the liquid medicine, push the liquid medicine out of the cartridge 1, and flow into the patient's throat and esophagus.

[0036] When the syringe 3 is pushed to the bottom and the push plate 4 still needs to move forward, the syringe 3 can be withdrawn. At this time, the external air enters the cartridge 1 through the one-way valve 22 and is located between the cartridge cover 2 and the push plate 4. Pushing the syringe 3 again can make the push plate 4 continue to move forward to squeeze the liquid medicine.

[0037] Less liquid medicine remains on the inner wall of the medicine cartridge 1, so the liquid medicine and the crushed solid medicine can be fully injected into the throat and esophagus of a critically ill patient.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
