Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The medicine feeder can provide convenience for bedridden patients, and medicine is usually taken in a mode of a mouth of the medicine feeder, and nursing staff is sometimes required to assist in injection.

Based on this, the present invention provides a current limiting type medicine feeder for bedridden patients, which limits the amount of liquid medicine flowing into the mouth through filling the space in the mouth, thereby avoiding the problem that a great amount of liquid medicine chokes the patient (the normal medicine feeder also considers the problem that the excessive amount of the liquid medicine flowing into the mouth can choke the patient, but because the invention aims at the bedridden patient, the bedridden patient is in a lying state, however, through practical observation, the patient is supported for medicine feeding by using the medicine feeder or is selected, because the lying state is opposite to the sitting state, the liquid medicine is easier to enter the respiratory tract to cause choking, so although the existing medicine feeder has been improved with respect to choke prevention, there is room for improvement in terms of choke prevention for lying patients), as shown in fig. 1, the medicine feeder of the present invention comprises a medicine storage bottle 110, in which liquid medicine (hereinafter referred to as medicine) is stored in the medicine storage bottle 110, and then a positional relationship between structures is determined by a use state of the medicine feeder, the medicine storage bottle 110 is provided at a bottom thereof with a medicine leakage mouth 120, and the medicine leaks out through the medicine leakage mouth 120, but since an inner tube 200 is provided in an axial direction in the medicine leakage mouth 120, and an inner side of the medicine leakage mouth 120 is adhered to an outer side of the inner tube 200, that is, the medicine in the medicine storage bottle 110 is not easily leaked out by sealing the medicine leakage mouth 120 with the inner tube 200, wherein:

one end of the inner tube 200 is positioned in the medicine storage bottle 110, the other end is used for entering the mouth, one side of the inner tube 200 entering the mouth is provided with an elastic ball mouth 320 (the ball mouth 320 is made of food grade silica gel or rubber material), the interior of the ball mouth 320 is hollow, and a hollow cavity formed by the ball mouth is communicated with the inner tube 200;

the bottom of the medicine storage bottle 110 is also provided with the ring mouth 310, the dotted line part in fig. 1 is the setting position of the ring mouth 310, therefore, it can be seen that the deformation space is enclosed by the ring mouth 310, the medicine leakage mouth 120 falls in the deformation space, when the ball mouth 320 is pressed, the hollow cavity inside the ball mouth contracts, then the air inside the hollow cavity is forced to enter the medicine storage bottle 110 through the inner tube 200, the air pressure in the medicine storage bottle 110 increases, thereby pressing the medicine in the medicine storage bottle 110, and the medicine leakage mouth 120 in the deformation space is spread after the medicine is pressed (the function of the deformation space is to provide enough deformation distance for the medicine leakage mouth 120, so that the medicine is spread by the medicine smoothly), a gap is formed between the spread medicine leakage mouth 120 and the inner tube 200, the medicine leaks out through the gap and flows into the mouth, and medicine feeding is realized.

In the process of realizing medicine feeding, since the lying patient can contain the ball mouth 320 in the mouth, most of the space in the mouth is occupied by the ball mouth 320, so that the space in the mouth for containing medicine is limited, the space in the mouth for containing medicine is reduced when lying down (the space in the mouth for containing medicine is assumed to be V1 when sitting down, the space in the mouth for containing medicine is V2 when lying down, wherein V2 is more than V1, once exceeding the space for containing medicine which is most comfortable, the space in the mouth for containing medicine is easy to choke, but V2 is fixed, the space in the mouth for containing medicine is more close to the space in the mouth, and the space for containing medicine is limited to adapt to V1, so that the possibility of the lying down patient to choke is reduced, more importantly, the lying down patient can feel the feeling of saturation in the mouth, so that the patient can independently control the medicine feeding quantity in the mouth, the medicine will not directly enter the mouth but is stored in the medicine storage bottle 110, as shown in fig. 3, the amount of the gas extruded into the medicine storage bottle 110 through the ball mouth 320 controls the amount of the medicine leaked from the medicine leakage mouth 120, the more the gas is extruded, the larger the pressure in the medicine storage bottle 110 is, the larger the gap formed by the medicine leakage mouth 120 is, the more the medicine leaked from the medicine leakage mouth is, and conversely, the less the medicine leaked from the medicine leakage mouth is, but the patient using the medicine feeder usually will not intentionally bite the ball mouth 320, so the ball mouth 320 can be extruded only through the shrinkage of the mouth space when breathing or when the mouth is water, the extruded gas amount is very small, even if the child uses the medicine, the saturated feeling brought by the ball mouth 320, the unintentional bite of the ball mouth 320 is not caused, the amount of the medicine leaked is limited, once the amount of the medicine flowing into the mouth is limited, the possibility that the patient lying down is choked is reduced, thereby preventing choking for the lying patient.

To sum up, as shown in fig. 1 and 2, the medicine storage bottle 110 and the medicine leakage nozzle 120 constitute a body 100 of the medicine feeder, which functions to store medicine, then an inner tube 200 is provided in the body 100, a nozzle 300 is provided at the bottom of the inner tube 200 (i.e., at one end extending outward from the body 100), the nozzle 300 is composed of a ring nozzle 310 and a ball nozzle 320, the nozzle 300 is contained in the nozzle, on the one hand, the space in the nozzle is occupied, on the other hand, gas is extruded through the contracted nozzle 300 in the space in the nozzle, the gas enters the body 100 under the guidance of the inner tube 200, when the nozzle 300 is contained in the nozzle, the body 100 faces upward, and then the medicine stored in the body 100 flows into the nozzle under the action of the gas pressure.

Note that, the height H1 of the inner tube 200 in the body 100 is higher than the height H2 of the liquid surface of the medicine in the body 100, as shown in fig. 2, the height H1 of the body 100 in the vertical state is the height of the top of the inner tube 200, as shown in fig. 6, and the height H1 of the body 100 in the inclined state is the height of the bottom edge of the top of the inner tube 200.

Because the medicine is used for a lying patient, the problem that the mouth 300 is upward is not considered, and in order to ensure that the medicine in the medicine storage bottle 110 is used as much as possible, an included angle B exists between the inner wall of the medicine storage bottle 110 connected with the medicine leakage mouth 120 and the horizontal plane L, the included angle B is preferably 15-75 degrees, and after the included angle B exists, the inner wall of the medicine storage bottle 110 is inclined by the high lateral medicine leakage mouth 120, so that the medicine flows into the medicine leakage mouth 120 as much as possible and then leaks into the mouth of the patient through the medicine leakage mouth 120.

In the first embodiment, as shown in fig. 3, the ball nozzle 320 is of a closed structure, because the ball nozzle 320 is closed, the outside air cannot be inhaled, which results in that the ball nozzle 320 cannot continuously output air into the medicine storage bottle 110, but there is an advantage in that the ball nozzle 320 is used for controlling the medicine dosage of a patient lying on the medicine bottle every time, because the volume of air extruded by the ball nozzle 320 is limited, the medicine leakage amount of the medicine leakage nozzle 120 can only be matched with the volume extruded by the ball nozzle 320 even if enough medicine exists in the medicine storage bottle 110, and when the medicine is applied again, the medicine storage bottle 110 is inverted, then the ball nozzle 320 and the inner tube 200 are extracted, the ball nozzle 320 is restored to the original shape, and air in the outside environment is inhaled, and then the inner tube 200 is inserted into the medicine leakage nozzle 120 for further application, but the medicine stored in the medicine storage bottle 110 can be used for multiple times when the precondition of the embodiment is implemented.
