Medical scale

Abstract

The invention discloses a medical scale. The medical scale comprises a body. The medical scale is characterized in that the body is a part of a bed or an infusion support; or the body is suitable for being hung or fixed to a transverse fixing rod of a fence handrail fixed to the side face / side faces of a bed frame or a bed edge and the bed frame / the bed edge; a hanging fixing device for hanging or fixing a drainage container is arranged or connected below the body. The medical scale can precisely weigh the weight or volume of liquid in a drainage bag, automatically add up the weight or volume of liquid in the common drainage bags and display and record use time. The medical scale can serve as a universal drainage container hanging device which is convenient and rapid to operate, achieves hanging fixing on multiple portions of the nursing bed in multiple modes, especially is hung and fixed on an installing fixing rod of a transverse handrail fence fixed to the side edge of the nursing bed and the side face of the nursing bed at the same time, can be rapidly installed and moved and is suitable for various drainage patients and wards.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a medical scale. Background technique [0002] After long-term clinical observation and testing, we found that various drainage containers, especially drainage bags, currently used in clinical practice have different manufacturers, models, specifications and styles, and the hanging rings or hanging holes configured for each product are different. Some only have hanging holes, and some only have hanging rings, especially the distances between the hanging holes at both ends of the drainage bag body vary widely. At present, the styles of nursing beds used in clinical practice vary greatly, and some have no hooks, and those with hooks are also fixed hooks with an opening upward. There are fence handguards and fixed rails or plates installed on the side of the bed. Since the fence handrails are movable, it is not suitable for fixing the drainage bag and also hinders the fixing of t...

AI Technical Summary

Problems solved by technology

[0003] First, the existing scales cannot be used as a conventional drainage container suspension device, and are not suitable for being fixed in the bed or fixedly hung on the edge of the bed, and the hooks are not suitable for long-term use as a hook for hanging the drainage container

The usual drainage bag is a soft bag, which cannot accurately measure the liquid in the bag. Nurses can only roughly estimate it or pour it out for measurement, which is very inaccurate and cumbersome. The critically ill patients who must use it can only use more complicated and high prices and charges. A lot of disposable precision metering drainage bags, or a few urine monitoring equipment configured in the ICU ward are used by a very small number of people, and the price and charge of the equipment are extremely high, and it is necessary to use complicated and expensive equipment. The special drainage bag, on the one hand, will cause a huge cost burden to some patients, on the other hand, most of the conventional drainage patients cannot be conveniently used and effectively, correctly and timely observed and recorded, which may cause misjudgment and delay the condition

[0004] Second, the drainage container, especially the bag hanging ring, is directly hooked on a hook. Since the two ends of the hanging ring are welded on both sides of the midline of the drainage bag body, the hanging ring is under a little force, which makes it easy to concentrate the weight on the center of the bag body. It is easy to cause wrinkles in the vertical middle of the bag, especially when there is a lot of drainage fluid, it may cause the anti-reflux membrane to fold, make the drainage difficult, and also reduce the bag capacity and affect the bag capacity. On the other hand, due to the existing nursing The hook of the bed is fixed, and the hook may be lifted when the drainage tube is pulled, causing the bag to fall off

[0005] Third, use a rope that goes through the suspension hole of the drainage bag to tie it to the edge of the bed. The operation is cumbersome, and it is not easy to master the correct way of binding. Because the patient may get up for activities or go out for inspection, it is necessary to untie the rope and perform repeated operations, which is very cumbersome

In addition, the rope is fixed, although it is firm, but its activity is small, and the slipknot fixed by the rope may be pulled or mishandled to become a dead knot, which cannot be untied in time

Moreover, when the drainage tube is pulled, the patient may experience discomfort because there is no room for buffering.

[0006] Fourth, the existing disposable drainage bags and precision drainage bags, the use time, drainage volume and other nursing staff can only manually record one by one, after each drainage, recalculation, re-recording, cumbersome and unintuitive, easy to make mistakes

[0007] Fifth, the precision drainage bag is for one-time use and cannot be used for more than a week, while the urine monitoring equipment has a large volume and weight, many and complicated parts, high cost and price, complicated operation, inconvenient transportation and handling, and urine The monitoring equipment also needs to be equipped with a special disposable drainage bag with complex structure and high price as the drainage fluid storage, which is not easy to popularize and use

[0008] Sixth, most of the current nursing beds have basically no gap between the bed frame and the bed board on the side of the bed, and the side is generally equipped with foldable handrails. It can only be hung or tied on the upper part of the handrail or the vertical fence pole. Since it is generally movable, when the handrail is opened, the drainage bag will rise together, which may cause drainage Fluid backflow and wrinkles in the middle of the bag affect patency and bag capacity

The installation position and method of the drainage bag suspension device are single, and there is no drainage bag suspension device or technology that can be fixed on the bedside or the horizontal handrail fence fixing rod installed on the outside of the bedside at the same time

[0009] Seventh, there is currently no practical value that can be used as a long-term, long-term and repeated stress like a normal drainage container hook, and can also maintain stability and accuracy as a drainage container for medical scales that accurately measure drainage liquid at any time Suspension

There is a plan to use springs for measurement. The springs are prone to fatigue, deformation and errors when they are stressed for a long time. In addition, their elasticity will act on the springs due to the vibration of the bed or the pulling of the drainage tube, which will cause the drainage container to vibrate and accelerate the fatigue and drainage of the spring. A series of problems such as splashing and polluting the environment

In other disclosed prior art solutions, it is inconvenient to install and disassemble or cannot move quickly after installation, or the versatility of hanging different drainage containers is poor, or its hooks may hurt people when they are facing outwards, or they are difficult to operate when hanging drainage bags, especially It is very inconvenient for patients to operate by themselves when getting on and off the bed
