Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bed having a double weighing device,

The present invention relates to a bed having a double weighing device, and more particularly, to a double weighing device capable of real-time measurement of a change in a minute variable weight caused by a total body weight of a user lying in a bed and food intake, respiration, The present invention relates to a bed equipped with a bed.

Generally, a weighing device is a device for measuring the load of an object to be measured and is classified into a load cell type and a magnetic balance type.

In the magnetic balance method, the load cell scale using the load cell method is mainly used since the measurement range is too small and the structure is relatively complicated.

The load cell scale measures a load using the strain of the load cell when a load is applied from the object to be measured. When the load cell is deformed, the strain gauge installed on the load cell detects a change in the voltage and measures a load .

Interest in baby healthcare, where newborns and infants continue to manage their health at hospitals and homes, is growing rapidly. Breathing and cardiac activity monitoring is required in the above-mentioned baby health care.

In other words, it is very important to monitor respiration and heartbeat in real time to quickly detect dyspnea or cardiac abnormality.

Generally, in the case of the bio-information measuring method, the measurement objects have a big objection to the measurement by attaching the electrode and the measuring instrument to the body (electrocardiogram measuring electrode, pulse wave measuring sensor, respiratory belt, etc.).

In recent years, there has been an active development of techniques for measuring biometric information while not touching the human body, giving no pain, and not being conscious of the user at all. Until now, bioinformatics measurement has been used to disturb the patient, to attach the electrode to the body, and to give the patient pain and discomfort. However, since non-contact and non-pain measurement methods are not conscious of people, they obtain biometric information in the life process. Therefore, they establish a system of regular (long-term and continuous) screening without rejection, anxiety and hassle, People who had difficulty fixing or compressing their body could easily measure it.

Unbounded biometric information measurement methods are very diverse, but can be broadly divided into two types. 1) To be worn on people like shoes, glasses, earrings, clothes, gloves and watches. 2) To attach to a person's equipment such as chair, car seat, car steering wheel, bed mattress, mirror, computer mouse, . Until now, the use of unbounded bioinformatics measurement has mostly been conducted for adults.

Therefore, 24-hour monitoring of biometric information is more important than anyone, so there is almost no proven non-contact, non-painful technique to be used for infants and children who need to apply non-binding biometric monitoring technology.

Among the non-restraint biometric information measurement methods, the method of attaching the sensor to the nose or putting the pulse wave measurement sensor on the foot in the form of a sock has a disadvantage that the sensor and the device are directly attached to the body,

Indirect measurement using indirect infrared camera, piezoelectric sensor (PVDF), Doppler radar, etc., is often the case when the accuracy is low, the cost is too high, or the clinical test is not completed due to the simulation study.

Recently, the hospital has installed a bed equipped with a metering device for thorough treatment management of the patient (infant).

That is, the total weight change of the patient on the bed can be checked in real time.

On the other hand, for efficient intensive treatment and management of newborn infants or infants, the total body weight is measured at the same time every day, and the relative body weight is measured according to the amount of water supplied to the body, amount of milk, amount of respiration, and feces.

However, in order to measure the comparative weight of the newborn baby or infant, it is troublesome and inconvenient to repeatedly move the newborn baby or the infant by a separate micro-variable weighing device. In addition, in the process of transferring to the weighing device, Crying or body movements are greatly increased, and precise measurement of variable weight change can not be performed quickly.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, a bed equipped with a double weighing device according to the present invention is provided with a through-hole 101 formed between a mattress M and a bed frame P, A second bed plate 200 coupled to the first bed plate 100 and corresponding to the penetrating portion 101 of the first bed plate 100; A connection unit 300 connecting the first bed plate 100 and the second bed plate 200 to each other and connecting the first bed plate 100 and the second bed plate 200 to each other; A first load cell 400 and a second load cell 500 installed at a lower portion of the second bed plate 200 and detecting a change in minute variable weight in real time.

First, the first bed plate 100 is installed between the mattress M and the bed frame P to stably support the mattress M.

To this end, the first bed plate 100 is made of a flat plate structure made of metal or aluminum material.

A hollow penetrating portion 101 having a predetermined size is formed on the inner side of the first bed plate 100.

The penetration portion 101 is configured to be coupled to a second bed plate 200 to be described later.

The second bed plate 200 is coupled to the penetration portion 101 of the first bed plate 100 and is made of the same material as the first bed plate 100.

The reason why the first bed plate 100 and the second bed plate 200 according to the present invention are separated from each other is that the total weight of the user lying on the mattress M from the configuration of the load cells 400, In addition, it is possible to perform real-time change of the user, that is, to take food, or to check the change of minute variable weight due to the stool, urine, or breath or pulse in real time, And management can be performed.

Especially, it is very useful for intensive care of infants whose cognitive ability and physical development are not developed.

Meanwhile, the connection unit 300 connects the first bed plate 100 and the second bed plate 200 to each other.

That is, the connection unit 300 is a component that physically connects the first bed plate 100 and the second bed plate 200. At this time, if the second bed plate 200 is fixed to the first bed plate 100 so that the second bed plate 200 can move in the vertical direction instead of being firmly fixed to the first bed plate 100, Can be accurately measured.

Here, the connecting unit 300 may have a hinge whose one end is fixed to the first bed plate 100 and the other end is fixed to the second bed plate 200.

The connection unit 300 may include an elastic band (not shown) having one end connected to the first bed plate 100 and the other end connected to the second bed plate 200.

The first load cell 400 is installed at a lower portion of the first bed plate 100 and detects a total load transmitted to the first bed plate 100 and the second bed plate 200 .

The first load cell 400 includes a rectangular parallelepiped sensor 410 installed on the first bed plate 100 and a pressure transmission support 420 installed on one side of the sensor 410.

Accordingly, when the user lays on the first bed plate 100, the load presses the pressure transfer support member 420, and the pressurized transfer support member 420 presses the sensor 410 again. At this time, the sensor 410 is deformed in proportion to the load, that is, the strain is converted into an electric signal by the strain gauge (not shown), and the signal is digitized by the electric device, can do.

The first bed plate 100 is provided with a first fixing bracket 120 for fixing and supporting the first load cell 400.

The first fixing bracket 120 may be formed on one side and the other side of the first bed plate 100, respectively.

It is preferable that the first load cell 400 is provided at one side and the other side of the first bed plate 100. However, the first load cell 400 is not limited to the first and second fixing brackets 120 and 120, One load cell 400 may be installed in two or more configurations along the circumference of the first bed plate 100.

In addition, the second load cell 500 is installed under the second bed plate 200, and detects a minute change in weight in real time.

3, the second load cell 500 includes a measurement sensor 510 for measuring a load value of a weight, a screw connection shaft 520 protruding from the upper surface of the measurement sensor 510, A sensitivity adjusting unit 530 coupled to the screw shaft 520 to adjust the sensitivity of the variable weight and a second sensing unit 530 disposed on the sensitivity adjusting unit 530 to contact the second bed plate 200 And a weight detection and transmission unit 540.

That is, when the load of the second bed plate 200 is generated, the load is transmitted to the screw coupling shaft 520 through the weight sensing transfer unit 540 installed under the second bed plate 200 do. The load transmitted to the screw shaft 520 is transmitted to the measurement sensor 510.

Then, when a load is applied to the measurement sensor 510, the measurement sensor 510 is elastically deformed and outputs an electric signal proportional to the amount of deformation.

Likewise, the first bed plate 100 is provided with a second fixing bracket 130 for fixing the second load cell 500.

The second fixing bracket 130 has a longitudinal direction crossing the lower center of the second bed plate 200 and is fixed to the first bed plate 100 by bending both longitudinal ends thereof.

The second load cell 500 may have a single structure disposed at a central portion of the second bed plate 200, but the present invention is not limited thereto.

By disposing the second load cell 500 at the center of the second bed plate 200, the second load cell 500 can be accurately deformed in proportion to the load applied without being influenced by other elements. Accordingly, the strain gauge provided on the measurement sensor 510 can sense the deformation and output an accurate electric signal, and consequently, can detect a minute change in the variable weight.

In addition, since the sensitivity adjusting unit 530 can efficiently adjust the sensitivity of the variable weight, the operation reliability of the second load cell 500 can be significantly improved.
The sensitivity adjusting unit 530 according to the present invention includes a screw coupling hole 531 to which the screw shaft 520 is coupled so as to be movable up and down along the longitudinal direction of the screw shaft 520, And a support groove 532 for supporting one end of the weight sensing and transmitting portion 540 in a state of receiving the weight.

4 shows another embodiment of the weight sensing and transmitting portion 540. Here, the weight sensing and transmitting portion 540 'includes a shaft sensing portion 540' having a spherical end portion contacting the second bed plate 200, ≪ / RTI > At this time, a receiving groove member 150 corresponding to the spherical shape of the weight sensing and transmitting portion 540 'is further formed on the bottom surface of the second bed plate 200.

The weight sensing and transmitting unit 540 may be an elastic member for elastically supporting the sensitivity adjusting unit 530 and the second bed plate 200.

Here, when the weight sensing / transmitting portion 540 is applied as an elastic member, since it reacts more sensitively to changes in vibration and pressure, it is possible to more precisely measure changes in micro-variable weight such as pulse, respiration, .

In addition, although not shown in the drawing, a vibration sensing unit capable of detecting a change in a minute variable weight transmitted to the second bed plate 200 can be provided, which can replace the second load cell 500.

Here, the vibration sensing unit may be constituted by a piezoelectric sensor for sensing vibration by converting the vibration into an electric pulse.

Since the configuration of the piezoelectric sensor is generally known in the art widely used in various industrial fields, detailed description thereof will be omitted.

The vibration sensing unit may include a photoelectric conversion element that can check the change of the microvariable weight according to an optical signal of the light emitting unit and the light receiving unit instead of the piezoelectric sensor.

Here, in the photoelectric conversion element, the plurality of short-wavelength light-receiving units detect a single light corresponding to a specific wavelength in accordance with the filter characteristic of the multi-wavelength light reflected from the mirror through irradiation from one light source, And a potential difference corresponding to a single light amount is generated. Thus, the oscillation displacement of the oscillating body vibrating in various axial directions can be calculated for each axis direction.

Such a photoelectric conversion element is similar to or similar to that described in Korean Patent Registration No. 0507132 (Vibration Displacement Calculation System and Method), and detailed description of the construction and operation will be omitted.

According to this configuration, by configuring the second load cell that is provided at the lower portion of the second bed plate and senses a minute change in the variable weight in real time, the change of the minute variable weight due to the user's food intake, respiration, Therefore, there is a very useful effect for efficient intensive treatment and management.

5 and 6 illustrate a bed equipped with a double metering device according to another embodiment of the present invention. The bed is provided between a mattress and a bed frame, and has a hollow penetrating portion 101 formed therein. A second bed plate 200 coupled to the plate 100 in correspondence with the through portion 101 of the first bed plate 100 and a second bed plate 200 provided below the first bed plate 100, A first load cell 400 sensing a load transmitted to the first bed plate 100 and the second bed plate 200 and a second load cell 400 installed below the first bed plate 100, And a third load cell 600 configured to support one to four of the first and second bed plates 200 to detect a change in the minute variable weight transmitted to the second bed plate 200.

The bed having the double weighing device according to another embodiment of the present invention plays a role of directly supporting the second bed plate 200 by the third load cell 600 instead of the connecting unit 300 described above .

Therefore, since the configuration of the connecting unit 300 for connecting the first bed plate 100 and the second bed plate 200 to each other can be omitted, the manufacturing cost and the manufacturing process can be further simplified .

The third load cell 600 is installed in a first fixing bracket 120 on which the first load cell 400 is installed.

In detail, the third load cell 600 installed in the first fixing bracket 120 may be provided at one side and the other side with the first load cell 400 interposed therebetween.
