Description

Technical Field

[0001] The present application relates to the technical field of geriatric care, and specifically to a medicine feeding tool for geriatric care. Background Art

[0002] Geriatric care is a comprehensive approach to care for the specific health needs and illnesses of older adults. Geriatric conditions can limit mobility and even make it difficult for some elderly individuals to take medications on their own. To facilitate medication administration, caregivers utilize tools such as syringe-like dispensers.

[0003] Existing medicine feeders have a shovel head integrated with the needle at the outlet to prevent contact with the nurse's hands and maintain hygiene. However, the shovel head makes it difficult to draw liquid medicine from the bottle into the syringe. Only liquid medicine from an open container or drinking water can be drawn. Therefore, existing medicine feeders are very inconvenient when taking and changing medicines, and their practicality is poor.

[0004] Therefore, the present application provides a medicine feeding tool for elderly care to solve the above problems. Utility Model Content

[0005] The present application provides a medicine feeding tool for elderly care, aiming to solve the problem of poor practicality of existing medicine feeders proposed in the background art, such as inconvenience in taking and changing medicines.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a medicine feeding tool for geriatric care, comprising a medicine cartridge, a medicine outlet nozzle fixed at the front end of the medicine cartridge, a medicine shovel fixed on the medicine outlet nozzle, a push rod mounted inside the medicine cartridge and moving axially along the medicine cartridge for pushing the medicine, and a piston head fixed at the front end of the push rod and in contact with the inner wall of the medicine cartridge.

[0007] A medicine introducing mechanism for connecting to an external medicine liquid container is provided on the side wall of the front end of the medicine cartridge.

[0008] The drug introduction mechanism includes a connector seat fixedly connected to the front side of the cartridge and communicating with the interior of the cartridge, a connector plugged into the connector seat, and a connector needle connected to the connector via an extension tube for insertion into the drug container. The connector has a one-way valve structure that only allows the drug liquid to enter the cartridge. Thus, through the design of the drug introduction mechanism, the drug feeding tool can directly draw drug liquid from the closed drug container into the cartridge by pulling the push rod. The one-way valve structure inside the connector prevents the drug liquid from flowing back into the extension tube when it is pushed out, greatly simplifying the process of removing and changing drugs and improving the practicality of the tool.

[0009] Preferably, the one-way valve structure includes a valve core that moves in the connector toward or away from the end of the connector away from the cartridge, at least three push rods fixed in a circular array on the side of the valve core and in contact with the inner wall of the connector, and a limiting ring fixed on the inner wall of the connector to prevent the valve core from falling out of the connector.

[0010] Preferably, the side wall of the connector has at least three snap rings distributed in a linear array along the axial direction of the connector, and the inner ring of the connecting seat has a plurality of snap rings corresponding to the snap rings.

[0011] Preferably, the side wall at the rear end of the cartridge is provided with a finger hook for finger buckle.

[0012] Preferably, the push rod tail end has a pull ring.

[0013] Preferably, the front end side wall of the cartridge has a baffle.

[0014] Preferably, a sealing ring is provided inside the bottom end of the connecting seat.

[0015] This medicine feeding tool for elderly care, through the design of the medicine introduction mechanism, can directly draw medicine liquid from the closed medicine liquid container into the medicine cartridge by pulling the push rod, and due to the one-way valve structure inside the connecting head, the medicine liquid is prevented from flowing back into the extension tube when it is pushed out, which greatly simplifies the process of taking and changing medicines and improves the practicality of the tool.

[0016] When the connector is inserted into the connector seat, the clamping ring gradually approaches the clamping protrusion in the connector seat along the axial direction of the connector. As the insertion goes deeper, the clamping rings meet the corresponding clamping protrusions one by one and produce elastic deformation until the clamping ring passes over the clamping protrusions and returns to its original shape, thereby achieving engagement. In combination with the sealing ring, this engagement connection is not only convenient for assembly and disassembly, but also has good sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] This embodiment provides a medicine feeding tool for elderly care, such as Figures 1-6 As shown, the medicine feeding tool for elderly care includes a medicine cartridge 1, a medicine outlet nozzle 2 fixed at the front end of the medicine cartridge 1, a medicine shovel 21 fixed on the medicine outlet nozzle 2, a push rod 3 sleeved inside the medicine cartridge 1 and moving axially along the medicine cartridge 1 for pushing the medicine, and a piston head 31 fixed at the front end of the push rod 3 and in contact with the inner wall of the medicine cartridge 1.

[0031] The side wall at the front end of the cartridge 1 is provided with a drug introduction mechanism 4 for connecting to an external drug liquid container.

[0032] The drug introduction mechanism 4 includes a connecting seat 41 fixedly connected to the front end side of the cartridge 1 and connected to the interior of the cartridge 1, a connector 42 inserted into the connecting seat 41, and a connector needle 44 connected to the connector 42 through an extension tube 43 for insertion into the drug liquid container. The connector 42 has a one-way valve structure that only allows the drug liquid to enter the cartridge 1.

[0033] During use, insert the connector 42 into the connecting seat 41 to complete the connection, then insert the connector needle 44 into the external medicine liquid container, keep the medicine cartridge 1 and the medicine liquid container connected, block the medicine outlet nozzle 2 with your fingers or a stopper, and then pull the push rod 3 to reduce the internal pressure of the medicine cartridge 1 to generate suction, and draw the medicine in the medicine liquid container into the medicine cartridge 1 through the extension tube 43. At this time, pull out the connector needle 44 from the medicine liquid container, transfer the medicine feeder to the patient's mouth, put the medicine outlet nozzle 2 into the patient's mouth, and then push the push rod 3 to squeeze the medicine in the medicine cartridge 1. Since the connector 42 has a one-way valve structure that only allows the medicine to enter the medicine cartridge 1, the medicine only flows out from the medicine outlet nozzle 2 and enters the patient's mouth. When feeding the medicine pellets, you can extract the clean water for feeding in the medicine cartridge 1 in advance, use the medicine shovel 21 to scoop the medicine pellets, and inject the clean water at the same time when feeding them into the patient's mouth to complete the medicine delivery.

[0034] Specifically, the one-way valve structure includes a valve core 422 that moves in the connector 42 toward or away from the end of the connector 42 away from the cartridge 1, at least three push rods 4221 fixed in a ring array on the side of the valve core 422 and in contact with the inner wall of the connector 42, and a limit ring 423 fixed on the inner wall of the connector 42 to prevent the valve core 422 from falling out of the connector 42; the valve core 422 is a movable component, and its position determines the opening and closing state of the one-way valve. When the connector needle 44 is inserted into the liquid medicine container and a certain suction force is applied, the valve core 422 will move toward the end of the connector 42 close to the liquid medicine container, thereby opening the channel and allowing the liquid medicine to flow into the cartridge 1; and when the liquid medicine stops flowing or the external pressure is insufficient to overcome the resistance of the valve core 422, the valve core 422 will remain in the closed position to prevent the liquid medicine from flowing back.

[0035] Furthermore, the side wall of the connector 42 has at least three snap rings 421 distributed in a linear array along the axial direction of the connector 42, and the inner ring of the connector seat 41 has several snap rings 411 corresponding to the snap rings 421, wherein the bottom end of the connector seat 41 has a sealing ring 412; when the connector 42 is inserted into the connector seat 41, the snap ring 421 will gradually approach the snap ring 411 in the connector seat 41 along the axial direction of the connector 42, and as the insertion deepens, the snap ring 421 will meet the corresponding snap ring 411 one by one and produce elastic deformation until the snap ring 421 passes over the snap ring 411 and returns to its original shape, thereby achieving engagement, and cooperates with the sealing ring 412 to make this engagement connection not only convenient for assembly and disassembly, but also has good sealing performance.

[0036] In addition, the side wall at the rear end of the cartridge 1 is provided with a finger latch 11 for latching the fingers, the rear end of the push rod 3 is provided with a pull ring 32, and the side wall at the front end of the cartridge 1 is provided with a baffle 12; when the caregiver needs to hold the cartridge 1 for medicine feeding, the caregiver can rest his fingers on the finger latch 11 to increase the stability and comfort of holding; the pull ring 32 is designed at the rear end of the push rod 3, which is convenient for the caregiver to push and pull the push rod 3, thereby controlling the push out of the medicine; when the medicine flows out of the medicine outlet 2, the baffle 12 can play a certain blocking role to prevent the medicine from splashing out of the outside of the cartridge 1, maintaining hygiene and cleanliness, and the baffle 12 can also be used as an auxiliary positioning point when feeding medicine, helping the caregiver to more accurately align the medicine outlet 2 with the patient's mouth.

[0037] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
