Description

Technical Field

[0001] This utility model belongs to the field of injection device technology, and in particular relates to a nutrient solution injection feeding device. Background Technology

[0002] In clinical practice, for some patients who are unable to swallow after surgery or have weak gastrointestinal digestive capacity, medical staff usually feed them with nutritional fluids. When the patient's condition permits, they can be fed by injection. When feeding patients by injection, medical staff need to use an injection feeding device, which delivers the nutritional fluid to the patient's stomach through a soft tube connected to the injection head from the nasal cavity and throat.

[0003] However, existing technologies have some problems: In actual use, when medical staff install the tubing on the injection head of existing injection feeding devices, they directly attach the tubing to the injection head. This installation method leads to an unstable connection between the tubing and the injection head. When medical staff inject the nutrient solution, the tubing is subjected to a large thrust from the flowing nutrient solution, which can easily cause it to accidentally fall off the injection head, thus affecting the normal injection work and causing the nutrient solution to spill on the patient. Therefore, we propose a nutrient solution injection feeding device. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a nutrient solution injection feeding device. By setting a clamping plate and a limiting component, the tubing sleeved on the injection head can be clamped and fixed to ensure the stability of the connection between the tubing and the injection head.

[0005] This utility model is implemented as follows: a nutrient solution injection feeding device includes an empty cylinder, an injection head body and a sleeve respectively provided on both sides of the empty cylinder, a piston rod is movably inserted into the inside of the empty cylinder, movable plates are provided on both sides of the injection head body on the empty cylinder, a clamping plate is fixedly connected to the side of the movable plate away from the empty cylinder, a fixing block is fixedly installed on the side of the movable plate, and the fixing block and the empty cylinder are connected by a limiting component.

[0006] Optionally, the empty cylinder is fixedly mounted with guide rails located on both sides of the injection head body, and the movable plate is slidably connected to the guide rails.

[0007] Optionally, the limiting component includes a toothed plate, which is fixedly mounted on the empty cylinder. A round rod is movably inserted into the fixing block. A locking block is fixedly connected to one end of the round rod near the toothed plate. The other end of the locking block is locked onto the toothed plate. A pull rod is fixedly connected to the other end of the round rod.

[0008] Optionally, a first spring is movably sleeved on the outer surface of the round rod, and the two ends of the first spring are respectively fixedly connected to the fixing block and the locking block.

[0011] Optionally, the sleeve is threaded onto the empty cylinder, and the sleeve is provided with a handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention, by setting up movable plates, clamps, and limiting components, allows medical personnel to push two clamps to move two movable plates in opposite directions after attaching the tubing to the injection head body during use.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 5 As shown in the figure, the nutrient solution injection feeding device provided by this utility model includes an empty cylinder 1. An injection head body 2 and a sleeve 3 are respectively provided on both sides of the empty cylinder 1. A piston rod 4 is movably inserted into the inside of the empty cylinder 1. Movable plates 5 are provided on both sides of the injection head body 2 on the empty cylinder 1. A clamping plate 6 is fixedly connected to the side of the movable plate 5 away from the empty cylinder 1. A fixing block 7 is fixedly installed on the side of the movable plate 5. The fixing block 7 and the empty cylinder 1 are connected by a limiting component.

[0023] Furthermore, guide rails 13 located on both sides of the injection head body 2 are fixedly installed on the empty cylinder 1, and the movable plate 5 is slidably connected to the guide rails 13.

[0024] Furthermore, the limiting component includes a toothed plate 8, which is fixedly installed on the empty cylinder 1. A round rod 9 is movably inserted into the fixing block 7. A locking block 11 is fixedly connected to one end of the round rod 9 near the toothed plate 8. The other end of the locking block 11 is locked onto the toothed plate 8. A pull rod 10 is fixedly connected to the other end of the round rod 9.

[0025] After the operator attaches the tubing to the injection head body 2, the two clamping plates 6 can be pushed to move in opposite directions to clamp the tubing onto the injection head body 2. Since the locking block 11 is locked onto the toothed plate 8, the clamping plate 6 can maintain the clamping effect on the tubing. By pulling the lever 10 to move the locking block 11 away from the toothed plate 8, the limitation on the clamping plate 6 can be released.

[0026] Furthermore, a first spring 12 is movably sleeved on the outer surface of the round rod 9, and the two ends of the first spring 12 are respectively fixedly connected to the fixing block 7 and the locking block 11.

[0027] By setting the first spring 12 to a compressed state, the elastic force of the first spring 12 will cause the locking block 11 to tend to move closer to the toothed plate 8, thereby enabling the locking block 11 to be stably locked onto the toothed plate 8.

[0028] Furthermore, square plates 14 located on both sides of the injection head body 2 are fixedly installed on the empty cylinder 1, and a second spring 15 is fixedly connected between the square plates 14 and the movable plate 5.

[0029] By setting the second spring 15 to a stretched state, due to the restoring effect of the elastic force of the second spring 15, the movable plate 5 and the clamping plate 6 will tend to move closer to the square plate 14. Thus, when the worker pulls the lever 10 to move the locking block 11 away from the toothed plate 8 and release the restriction on the clamping plate 6, the clamping plate 6 can return to its original position under the tension of the second spring 15.

[0030] Furthermore, the clamp 6 has an arc-shaped appearance, and the inner surface of the clamp 6 is provided with anti-slip texture.

[0031] Furthermore, the sleeve 3 is threaded onto the empty cylinder 1, and the sleeve 3 is provided with a handle 16.

[0032] By unscrewing the sleeve 3 from the empty cylinder 1, the piston rod 4 can be pulled out of the empty cylinder 1, making it easier for workers to clean the empty cylinder 1 and the piston rod 4.

[0033] Working principle: After medical staff fill the empty cylinder 1 with nutrient solution, when they need to connect the tubing to the injection head body 2 for injection, they can first put the tubing on the injection head body 2, then push the two clamping plates 6 to move towards each other and stretch the second spring 15, so that the clamping plates 6 clamp and fix the tubing on the injection head body 2. Due to the elastic force of the first spring 12, the locking block 11 will be locked on the toothed plate 8, thereby limiting the clamping plate 6 and maintaining the clamping effect on the tubing. This ensures the connection stability between the tubing and the injection head body 2, and the injection can then be performed. When the tubing needs to be removed after the injection is completed, the medical staff can pull the pull rod 10 to move the locking block 11 away from the toothed plate 8. Under the elastic force of the second spring 15, the movable plate 5 will drive the clamping plate 6 to return to its original position, and the tubing can be pulled off the injection head body 2. Finally, the sleeve 3 is unscrewed to remove the piston rod 4, and the empty cylinder 1 and piston rod 4 can be cleaned.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
