Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a controllable volume replenishment device for a nutrient solution bag. Background Technology

[0002] A medical feeding bag is a plastic bag that temporarily stores the nutritional fluids a patient needs and delivers them to the patient through an IV line. Patients with gastrointestinal damage or those unable to chew food normally after surgery can use feeding bags to receive their nutritional fluids.

[0003] In related technologies, disposable feeding bags include a bag body, a discharge tube, and an adjusting ball bearing. One end of the discharge tube is fixedly connected to the bag body, and the other end is connected to a feeding tube inserted into the patient's body. Nutrient solution is poured into the feeding bag body, and then the bag body is suspended. Gravity allows the nutrient solution contained in the bag to slowly drain through the discharge tube and into the feeding tube to supply the patient. Nursing staff manually adjust the ball bearing, judging the current flow rate based on experience.

[0004] Regarding the aforementioned technologies, the inventors believe that they have the following drawbacks: different patients have different conditions and needs. Adjusting the flow rate solely based on the experience of nursing staff to adjust the ball bearing results in a deviation between the current flow rate and the flow rate that the patient can tolerate, causing discomfort to the patient and potentially leading to choking. Utility Model Content

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a controllable volume replenishment device for nutrient solution bags, including a storage cylinder 1, a baffle 2 slidably connected inside the storage cylinder 1, an outlet tube 3 fixedly connected to the baffle 2 towards the bottom of the storage cylinder 1, the area between the baffle 2 and the storage cylinder 1 communicating with the interior of the outlet tube 3, a connecting cap 4 threadedly connected to the top of the storage cylinder 1, a through hole 5 for the outlet tube 3 to extend from the bottom of the storage cylinder 1, a driving adjustment component connected to the bottom of the outlet tube 3, and an outlet component rotatably connected inside the outlet tube 3.

[0026] A fixing plate 6 is provided below the storage cylinder 1. A through hole 7 is provided on the fixing plate 6. A conveying pipe 8 is inserted through the through hole 7. One end of the conveying pipe 8 is fixedly inserted into the bottom of the outlet pipe 3. A support rod 9 is fixed between the fixing plate 6 and the storage cylinder 1.

[0027] The storage cylinder 1 can store nutrient solution, which is delivered to the body by inserting a delivery tube 8 into the bottom of the outlet tube 3.

[0028] Meanwhile, ear plates 10 are fixed on the side of the storage cylinder 1. Two ear plates 10 are symmetrically arranged, so that the entire storage cylinder 1 can be suspended and fixed through the ear plates 10 to facilitate the delivery of nutrient solution.

[0029] A drive adjustment component is provided inside the storage cylinder 1 to adjust the amount of nutrient solution input into the storage cylinder 1. Specifically, the drive adjustment component includes a connecting rod 11 fixed to the bottom of the baffle 2. A piston rod 12 is inserted and connected to the end of the connecting rod 11 away from the baffle 2. A cylinder 13 is connected to the end of the piston rod 12 away from the connecting rod 11. The connecting rod 11 is symmetrically arranged about the middle of the baffle 2.

[0030] Subsequently, driven by cylinder 13, piston rod 12 moves up and down, driving connecting rod 11 to move up and down. When connecting rod 11 moves down, it causes baffle 2 to move down, thereby increasing the area between baffle 2 and the top of storage cylinder 1, thus increasing the amount of nutrient solution placed inside storage cylinder 1. Conversely, it decreases the amount of nutrient solution placed inside storage cylinder 1. A graduation strip 16 is also provided on the outside of storage cylinder 1.

[0031] Specifically, a pointer rod 14 is fixed on the side of the connecting rod 11, and a pointer block 15 is fixed on the end of the pointer rod 14 away from the connecting rod 11. Scale bars 16 are provided on both sides of the storage cylinder 1. Several scale bars 16 are provided along the length of the storage cylinder 1, and the pointer block 15 is provided on the side of the scale bar 16.

[0032] The pointer rod 14 moves synchronously with the connecting rod 11, and the external pointer block 15 points to the corresponding scale bar 16, which indicates the amount of nutrient solution inside the storage cylinder 1, thus facilitating the control of the amount of nutrient solution delivered each time.

[0033] In this embodiment, in order to ensure uniform delivery of nutrient solution, a drive adjustment component is provided inside the outlet tube 3. Specifically, the drive adjustment component includes an annular support 17 fixed inside the outlet tube 3. A screw 18 is rotatably connected inside the annular support 17. One end of the screw 18 is connected to a bevel gear set 19. The end of the bevel gear set 19 away from the screw 18 is connected to a drive shaft 20. The drive shaft 20 extends along the side of the outlet tube 3, and a motor 21 is fixed at the extended end. The motor 21 is fixed on the outside of the outlet tube 3.

[0034] After the motor 21 is turned on, the motor 21 can drive the bevel gear set 19 to rotate. The bevel gear set 19 includes two bevel gears arranged in a vertical direction. Through the direction change of the bevel gears, the internal screw 18 is driven to rotate, thereby uniformly discharging the nutrient solution. At the same time, the flow rate can be controlled by controlling the output power of the motor 21.

[0035] Both the motor 21 and the cylinder 13 are electrically connected to the power supply module 22. The power supply module 22 is fixed on the side of the storage cylinder 1 and has a control button 23 integrated on it.

[0036] The power supply module 22 uses existing replaceable batteries or rechargeable battery packs. Its external power supply integrates control buttons 23, which are used to control the opening and closing of the motor 21 and cylinder 13, and also to control the output power adjustment of the motor 21.

[0037] The working principle of this utility model is as follows: When delivering nutrient solution to a patient, the position of the baffle 2 is adjusted according to the required amount by driving the cylinder 13. The required amount is confirmed according to the position of the scale strip 16 and the pointer block 15 on the outside of the storage cylinder 1. After adjusting the baffle 2, the connecting cover 4 on the top of the storage cylinder 1 is unscrewed, and the required nutrient solution is introduced into the storage cylinder 1. The connecting cover 4 is screwed back in and closed. The motor 21 is turned on, and the nutrient solution is delivered into the patient's body along the delivery tube 8.

[0038] The storage cylinder 1 is made of transparent medical-grade polyethylene, and the connecting cap 4 can be appropriately opened with ventilation holes to prevent the nutrient solution from flowing poorly inside.
