Abstract
Description
Technical Field
[0001] This application relates to the field of medicine feeder technology, and more specifically, to a medicine feeder with anti-spillage function. Background Technology
[0002] Medication feeders are nursing aids. Feeding medication to children, the elderly, and some clinical patients is a common nursing procedure due to their own conditions. Hospitalized patients, especially the elderly or critically ill patients, cannot take their own medication, so nursing staff need to feed them medication.
[0003] The prior art document CN219323690U provides a medication feeder that includes a filter and a drainage tube. When medical staff administer medication to elderly patients, the medication flows through the filter, where an internal filter screen filters out larger, undissolved drug residues, preventing choking. After use, the filter can be removed for cleaning. The filtered medication is then administered to the elderly patient through the drainage tube. Since taste perception largely relies on the tongue, the drainage tube significantly reduces contact between the medication and the tongue, minimizing discomfort for the elderly patient during administration. The device boasts higher efficiency and safety, and its simple installation and disassembly greatly enhance convenience for medical staff and improve user experience.
[0004] Although the device has many beneficial effects, it still has the following problems: when administering medication to elderly and pediatric patients, staff may easily deliver a large amount of medication into the patient's mouth at once, which may cause the elderly and pediatric patients to choke, thus reducing the protective performance for the elderly and pediatric patients. In view of this, we propose a medication feeder with anti-spill function. Utility Model Content
[0005] This application provides a medication feeder with anti-spillage function, which solves the technical problem in the prior art where, when administering medication to elderly and child patients, staff can easily deliver a large amount of medication into the patient's mouth at once, which can easily cause the elderly and child patients to choke, thus reducing the protective performance for elderly and child patients. This application achieves the technical effect of preventing excessive medication from being administered at once when staff administer medication to elderly and child patients, thereby preventing choking and improving the protective performance for children and elderly patients.
[0006] This application provides a medicine feeder with anti-spillage function, including: an injection cylinder;
[0007] A liquid outlet tube is fixedly connected through one side of the syringe. A piston is provided inside the syringe. A push plate is fixedly connected to one side of the piston via a connecting rod. A displacement plate is fixedly connected to the side of the push plate near the connecting rod. A blocking mechanism for blocking the displacement plate is provided on one side of the syringe.
[0008] The blocking mechanism includes a fixed block, which is fixedly connected to one side of the injection cylinder. A connecting plate is provided on one side of the fixed block, and multiple stop bars for blocking the displacement plate are slidably connected through one side of the connecting plate.
[0009] By adopting the above technical solution and setting up a displacement plate and blocking mechanism, when staff administer medication to elderly and pediatric patients, it is possible to prevent excessive medication from being administered at one time, thereby preventing choking on children and elderly patients and improving the protective performance for children and elderly patients.
[0010] Optionally, a pull plate is fixedly connected to one end of the stop bar, and a spring is fixedly connected between the pull plate and the connecting plate, with the spring sleeved on the outside of the stop bar.
[0011] By adopting the above technical solution and setting up a pull plate and a spring, when the operator needs to pull the stop bar, the pull plate must first be pulled to stretch the spring, thereby increasing the resistance to the movement of the pull plate and the stop bar and preventing the stop bar from moving arbitrarily.
[0012] Optionally, a ball groove is provided at the other end of the stop bar, and a universal ball is installed in the ball groove.
[0013] By adopting the above technical solution and setting up a ball groove and a universal ball, when the worker pulls the stop lever to a position away from the displacement plate, the worker can continue to move the push plate and the displacement plate, and then release the pull plate and the stop lever, so that the universal ball moves to the position in contact with the displacement plate with the help of the spring force, without affecting the movement of the displacement plate, so that the worker does not need to keep pulling the displacement plate by hand.
[0014] Optionally, the connecting plate and the fixing block are both provided with threaded grooves on the same side, and a threaded rod is threadedly connected in the threaded groove.
[0015] By adopting the above technical solution and setting threaded grooves and threaded rods, when staff do not need to control the amount of medication given to patients, they can turn the threaded rod to disengage it from the threaded groove, thereby removing the connecting plate and the stop bar.
[0016] Optionally, a threaded ring is threaded on the outside of the syringe, and a sponge sleeve is fixedly connected to one side of the threaded ring. The sponge sleeve is fitted onto the outside of the liquid outlet tube.
[0017] By adopting the above technical solution, and by setting up a threaded ring and a sponge sleeve, when staff are feeding medication to patients, once the medication flows out of the patient's mouth, the sponge sleeve that comes into contact with the patient's lips can absorb the liquid, preventing the liquid from spilling or flowing onto the patient's clothing.
[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0019] 1. By setting up a displacement plate and a blocking mechanism, when staff administer medication to elderly and pediatric patients, it is possible to prevent excessive medication from being administered at one time, thereby preventing choking on elderly and pediatric patients and improving the protective performance for them.
[0020] 2. By setting up a pull plate and a spring, when the operator needs to pull the stop lever, they must first pull the pull plate to stretch the spring, thereby increasing the resistance to the movement of the pull plate and the stop lever and preventing the stop lever from moving arbitrarily.
[0021] 3. By setting up ball grooves and omnidirectional balls, when the operator pulls the stop lever to a position away from the displacement plate, the operator can continue to move the push plate and the displacement plate, and then release the pull plate and the stop lever, so that the omnidirectional balls move to the position in contact with the displacement plate with the help of the spring force, without affecting the movement of the displacement plate, so that the operator does not need to keep pulling the displacement plate by hand.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.
[0027] Reference Figure 1 and Figure 2This application discloses a medicine feeder with anti-spillage function. The medicine feeder with anti-spillage function includes: a syringe 1;
[0028] A liquid outlet tube 2 is fixedly connected through one side of the syringe 1. A piston 4 is provided inside the syringe 1. A push plate 6 is fixedly connected to one side of the piston 4 through a connecting rod 5. A displacement plate 7 is fixedly connected to the side of the push plate 6 near the connecting rod 5. A blocking mechanism 3 is provided on one side of the syringe 1 to block the displacement plate 7.
[0029] The blocking mechanism 3 includes a fixing block 36, which is fixedly connected to one side of the syringe 1. A connecting plate 31 is provided on one side of the fixing block 36. Multiple baffles 32 for blocking the displacement plate 7 are slidably connected through one side of the connecting plate 31, so as to prevent the liquid medicine from being pushed into the patient's mouth in large quantities and causing elderly or child patients to choke.
[0030] Reference Figure 2 and Figure 3 A pull plate 33 is fixedly connected to one end of the stop bar 32. A spring 34 is fixedly connected between the pull plate 33 and the connecting plate 31. The spring 34 is sleeved on the outside of the stop bar 32 to prevent the stop bar 32 from moving at will.
[0031] Reference Figure 2 and Figure 3 The other end of the stop bar 32 is provided with a ball groove, and a universal ball 35 is installed in the ball groove, so that when the displacement plate 7 moves, the staff does not need to keep pulling the pull plate 33 by hand, thus reducing the resistance when the displacement plate 7 moves.
[0032] Reference Figure 2 and Figure 3 Both the connecting plate 31 and the fixing block 36 have threaded grooves on the same side, and a threaded rod 37 is threadedly connected in the threaded grooves. This allows the staff to quickly remove the connecting plate 31 and the stop rod 32 when they do not need to control the amount of injected medicine.
[0033] Reference Figure 1 and Figure 2 The top and bottom of the syringe 1 are fixedly connected with holding rings, which makes it easy for the staff to grip the two holding rings and push the push plate 6 to move, preventing the syringe 1 from slipping out of their hands.
[0034] Reference Figure 1 and Figure 2 The syringe 1 is threaded with a threaded ring 8 on the outside. A sponge sleeve 9 is fixedly connected to one side of the threaded ring 8. The sponge sleeve 9 is fitted on the outside of the liquid outlet tube 2, so as to prevent the liquid from flowing directly onto the patient's clothes.
[0035] The implementation principle of a medication feeder with anti-spill function in this application embodiment is as follows: When medication needs to be administered to elderly or child patients, the push plate 6 can be pushed to move the connecting rod 5 and the displacement plate 7. The movement of the connecting rod 5 can move the piston 4, thereby delivering the medication through the outlet pipe 2 into the patient's mouth. When the displacement plate 7 moves to the position where it abuts against the first stop 32, the push plate 6 can no longer move towards the syringe 1, preventing the staff from administering too much medication at once, which could cause elderly or child patients to choke. When it is necessary to continue administering medication, the staff can pull the first pull plate 33 to move the first stop 32 and pull the spring 34, so that the first stop 32 can be moved, thus preventing the piston 4 from being injected. One stop lever 32 separates from the displacement plate 7. Then, the operator can continue to push the push plate 6 to move the connecting rod 5, the displacement plate 7, and the piston 4. When the displacement plate 7 can continue to move, the operator can release the first pull plate 33, causing the spring 34 to rebound and move the first pull plate 33 and the first stop lever 32 toward the displacement plate 7 until the universal ball 35 contacts the displacement plate 7. When the displacement plate 7 moves, the universal ball 35 will roll in the ball groove until the displacement plate 7 contacts the second stop lever 32. Then, the second stop lever 32, the third stop lever 32, and the remaining stop lever 32 are operated in sequence according to the above method to prevent excessive liquid from being delivered at one time.
[0036] This application provides a medicine feeder with anti-spillage function. By setting a displacement plate 7 and a blocking mechanism 3, when staff feed medicine to elderly patients and children, it can prevent excessive medicine from being fed at one time, thereby preventing children and elderly patients from choking, and thus improving the protection performance for children and elderly patients.
