Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, in particular to a feeding device for elderly cardiovascular patients. Background Art

[0002] Due to their illness and physical condition, some elderly cardiovascular patients may have difficulty swallowing or be unable to eat. At this time, the patients cannot eat solid food, so they need to be given liquid food. For some elderly people who are not conscious enough or do not have the ability to eat actively, they need to use a feeding device to help them eat. The shape and principle of the current common feeding devices are similar to those of syringes. Although the feeding function can be realized, due to the limited capacity, the head of the feeding device needs to be repeatedly placed in and taken out of the patient's mouth, and the head end needs to be repeatedly inserted into the container for liquid food to absorb, which is inefficient and complicated to operate. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a feeding device for elderly cardiovascular patients, which does not require the feeding tool to be repeatedly removed from the patient's mouth, nor does it require the feeding tool to be repeatedly inserted into a container containing food for extraction, thereby improving the efficiency of feeding and simplifying the operation.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a feeding device for elderly cardiovascular patients, comprising a pumping tube body, a push-pull rod is inserted into the interior of the pumping tube body, one end of the push-pull rod is connected to the silicone piston, one end of the pumping tube body is connected to a first screw joint, one end of the first screw joint is threadedly connected to a three-way pipe, the other two ends of the three-way pipe are respectively connected to a first one-way valve and a second one-way valve, one end of the first one-way valve is connected to a first hose, one end of the first hose is connected to a second screw joint, the second screw joint is threadedly connected to a liquid food storage tank, one end of the second one-way valve is connected to the second hose, one end of the second hose is connected to a nipple joint, an outer side of the nipple joint is provided with an integrally formed arc-shaped guard plate, the nipple joint is connected to a silicone nipple, a side surface of the arc-shaped guard plate is provided with a sponge embedding groove, and a sponge is embedded and installed on the inner side of the sponge embedding groove.

[0005] The beneficial effects of the utility model are as follows: when the device is used, the pumping tube body is threadedly connected to the three-way tube through the first screw joint, and the liquid food storage tank is threadedly connected to the second screw joint, and the silicone nipple is put into the patient's mouth for the patient to hold it in his mouth, and then two fingers can be pressed against the side of the finger support plate close to the finger ring, and one finger can be inserted into the finger ring to pull the push-pull rod outward to drive the silicone piston to move. Under the action of negative pressure, the first one-way valve opens, so that the liquid food in the liquid food storage tank is sucked into the pumping tube body through the first hose, and then the two fingers pressed against the finger support plate can be transferred to the other side of the finger support plate and pressed against the other side of the finger support plate. The liquid food in the pumping tube body can be pushed by pressing the push-pull rod. During the pushing process, under the action of pressure, the second one-way valve opens, and the liquid food enters the second hose and the silicone nipple, and is input into the patient's mouth through the extrusion hole. After completing one pushing action, the push-pull rod can be pulled again. At this time, the second one-way valve is closed under the action of negative pressure, and the first one-way valve opens, and the liquid food in the liquid food storage tank is pumped into the pumping tube body again. There is no need to repeatedly move the feeding tool away from the patient's mouth, nor is there any need to repeatedly insert the feeding tool into the container containing food for extraction, thereby improving the efficiency of feeding and simplifying the operation.

[0006] Because of the arc-shaped guard plate and sponge, if food overflows from the corners of the patient's mouth, it can be directly absorbed by the sponge to avoid flowing along the patient's cheek onto the bed.

[0007] In order to provide support points for pushing and pulling the push-pull rod:

[0008] As a further improvement of the above technical solution: the other end of the push-pull rod is connected to the finger ring, and an integrally formed finger support plate is provided on the outer side of one end of the pumping tube body.

[0009] The beneficial effect of this improvement is that the finger ring and the finger support plate are used to provide support points for pushing and pulling the push-pull rod.

[0010] To avoid clogging of the extrusion hole:

[0011] As a further improvement of the above technical solution: a cross-shaped extrusion hole is provided through one end of the silicone nipple.

[0012] The beneficial effect of this improvement is that the cross-shaped extrusion hole can expand as the silicone nipple deforms, thereby avoiding blockage.

[0013] To improve the comfort and fit of the curved guard against the patient's face:

[0014] As a further improvement of the above technical solution: the arc-shaped guard plate is made of variable soft PP material.

[0015] The beneficial effect of this improvement is that the arc-shaped guard plate adopts a variable soft PP material, which improves the comfort and fit of the arc-shaped guard plate to the patient's face.

[0016] In order to make the sponge groove firmly embedded in the sponge groove:

[0017] As a further improvement of the above technical solution: the sponge embedding groove and the arc-shaped protective plate are bonded by waterproof double-sided tape.

[0018] The beneficial effect of this improvement is that the sponge embedding groove and the arc-shaped guard plate are bonded by waterproof double-sided adhesive, so that the sponge embedding groove is firmly embedded in the sponge embedding groove.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
