Description

Portable Weight Measurement Device for disabled persons}

The present invention relates to a patient weight measuring device, and in particular, to a portable patient weight measuring device that can be easily stored in a small volume in a foldable form, and allows the patient to get up from the bed and measure the weight.

It will be said that the patient's weight is important in grasping the patient's nutritional status or the appropriateness of the prescription. The most common weight scale for measuring weight is a box-type placed on the floor, and it was difficult to accurately measure the weight because the patient's body could not be fixed. Accordingly, devices for easily measuring the weight of patients (including those with disabilities and the elderly) have been proposed.

One example is a weight device equipped with a handle so that a patient can hold a handle and measure their weight stably. However, it is a bulky form, it is not easy to move, and there is a problem that the patient cannot get up from the bed and measure the weight. For example, it is not possible to move the weight device between the beds in a space where a number of beds are arranged.

Another example of a patient weight device is a wheelchair-based weight device. Such a device has an advantage of measuring weight while riding in a wheelchair or measuring weight while sitting in a chair, but there is a problem that a considerable error is included in the measured value due to the movement of the patient.

Another example of a patient weighing device is a bed or hammock-based scale. A medical bed is equipped with a scale at the bottom of the moving wheel to continuously receive a load by the weight of the bed and the patient's weight, so damage or malfunction of the device may occur. In particular, a weight measuring device using a hammock is used to measure the patient's weight. The patient's body moved a lot, causing discomfort and hassle.

As another example of a patient's weight device, a weight scale for a patient (Utility Registration No. 20-0398873) has been proposed that can quickly and accurately measure the weight of the patient without causing any strain on the patient's body. However, the prior art is a structure in which the patient is hung on a scale to measure the weight, which is inconvenient to use.

As described above, in the conventional weight device, there is a problem in that a patient with discomfort needs to move to the measuring device in order to measure the weight, along with the inconvenience and hassle, and the occurrence of an error in the measured value.

On the other hand, the above-described weight apparatus is basically composed of only a device for measuring body weight, and it was not possible to measure and analyze body composition (inbody) such as body fat or obesity. To do this, it is necessary to move to a device capable of such a test, but the movement itself was not easy for patients with discomfort.

Accordingly, an object of the present invention is to solve the above-described problems, and to provide a portable patient weight measuring device capable of measuring a patient's weight right next to a patient's bed.

Another object of the present invention is to provide a portable patient weight measuring device that can be folded and stored when not in use, and that the volume is small in the folded state and can be easily stored even in a small space.

Another object of the present invention is to provide a portable patient weight measuring device that can be conveniently used by patients by enabling not only body weight but also body composition test.

The present invention for achieving the above object is provided with a pair of support rods extending upwardly, a fixed plate on which a moving wheel is mounted on a lower surface; A horizontal bar connecting the upper end of the support bar; A moving bar located below the horizontal bar and connecting between the support bars; A motor providing a driving force so that the moving bar moves in a vertical direction along a support bar; And a measurement assembly provided on one side of the fixed plate and having a first state in contact with a floor surface or a second state in contact with a floor surface according to the motor driving.

Preferably, the measurement assembly comprises: a load cell for measuring weight; A support plate provided with the load cell; A scaffold provided on the upper surface of the support plate; And a pair of handles provided on both sides of the support plate.

Preferably, for the first state or the second state, a pair of first joint links between the moving bar and the support plate; And a pair of second joint links between the support plate and the fixed plate.

Preferably, the handle part has a rod shape of a predetermined length in which both ends are bent in different directions, the lower part is inserted into the guide groove formed in the support plate, and the upper part is equipped with a sensor for measuring body composition.

Preferably, an articulated link member is coupled between the handle portion and the support plate, and the articulated link member includes two unit links arranged to be offset in a direction of 90 degrees to each other.

Preferably, when the articulated link member is driven by a link and the measurement assembly is in the first state or the second state, the lower end part slides within the guide groove.

Preferably, it further comprises an auxiliary plate provided on the other side of the fixed plate, a pair of third joint links between the moving bar and the auxiliary plate for the horizontal or vertical state of the auxiliary plate; And a pair of fourth joint links between the auxiliary plate and the fixed plate.

Preferably, the first and second joint links, and the third and fourth joint links are driven symmetrically to each other.

Preferably, in the first state, the support plate and the auxiliary plate are positioned below the moving wheel to contact the bottom surface.

Preferably, in the second state, only the moving wheel of the fixed plate contacts the bottom surface.

Preferably, the motor is a liner motor in which the motor shaft vertically reciprocates.

According to the mobile patient weight measuring device of the present invention as described above has the following effects.

First, the patient's weight measuring device can be folded in the case of non-measurement, so it can be sufficiently stored even in a narrow space, thereby improving space efficiency.

And since the measurement requires only a narrow space in which the support plate and the auxiliary plate can be unfolded, the weight measuring device can be placed between the beds even if the distance between the beds on which the patient is lying is narrow. You can move and measure your weight. As such, the patient's travel distance can be minimized, which will increase the patient's convenience.

In addition, when measuring weight, since the support plate and the auxiliary plate are in contact with the floor surface and the moving wheel falls, it is possible to measure the weight in a stable posture.

In addition, a body composition test sensor is built into the handle, so it is possible to measure and test both body weight and body composition while minimizing the movement of the patient.

And the weight measuring device has a built-in communication module. Therefore, it is easy to manage the patient because the weight or body composition value can be easily checked from an external device.

However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. However, these embodiments are provided to complete the disclosure of the present invention and to fully inform the scope of the invention to those of ordinary skill in the art to which the present invention pertains, and the present invention is defined by the scope of the claims. It just becomes. Therefore, the definition should be made based on the contents throughout this specification.

The present invention is a mobile patient weight measuring device capable of measuring body weight and body fat while minimizing the moving distance of a patient with reduced mobility, and the present invention will be described in more detail based on the embodiments shown in the drawings below. do.

See FIGS. 1 to 3B. The mobile patient weight measuring apparatus 10 may have two structures: an unfolded state (first state) capable of measuring weight or a folded state (second state) capable of moving/storing.

The mobile patient weight device 10 is provided with a fixed plate 100 provided with a pair of support rods 110 extending upwardly. In the fixed plate 100, a moving wheel 101 for movement is installed on the lower surface, and during weight measurement, the moving wheel 101 is connected to the floor surface to prevent movement of the weight measuring device 10. Spaced apart. Of course, while the weight is measured, the movement of the weight measurement device 10 is prevented by the support plate 220 and the auxiliary plate 500, which will be described later, but it can be viewed as a configuration for more reliable movement prevention.

In addition, a cutting groove 102 is formed in the fixing plate 100, and a coupling link 104 is provided at one end hingedly coupled to the cutting groove 102 and coupled to the support plate at the other end. The support plate 220 positioned vertically in the first state by the cut groove 102 is not positioned outside the fixed plate 100, and the coupling link 104 supports the movement of the support plate 220. Plays a role.

The support rods 110 are formed in a pair from both ends of the upper surface of the fixing plate 100 toward the upper side, and the horizontal bar 112 is connected to the upper end of the support rod 110, so that the overall shape is approximately the same as the ∩ shape.

An installation bracket 120 is provided on the upper side of the support bar 110. The installation bracket 120 may be referred to as a space in which a module for convenient specifications is mounted. In the embodiment, an input/output device 600 of a predetermined size is mounted. Although not shown, the input/output device 600 includes mode setting buttons for measuring weight or body composition, a display unit displaying a measured value, and a wireless communication module for communicating with an external device.

A handle 122 may be provided in the mounting bracket 112, and a sensor capable of measuring body composition is embedded in the handle 122. In the embodiment, the handle directly gripped by the patient provides a structure integrally provided with the measurement assembly 200 described below, but the handle 122 may also be formed on the mounting bracket 120 in this way.

A moving bar 130 is coupled between the support rods 110. The moving bar 130 has coupling brackets 132 integrally formed at both ends, and a coupling hole (not shown) formed in the coupling bracket 132 is fitted into the outer circumferential surface of the support rod 110. The coupling hole is inserted into the support rod 110 so that the moving bar 130 moves in the vertical direction along the outer circumferential surface of the support rod 110 by a driving force to be described later.

A motor 140 is installed between the horizontal bar 1120 and the moving bar 130. The motor 140 employs a liner motor, a motor body 142 coupled to the horizontal bar 112, and a motor body It includes a shaft 144 that extends from 142 and has an end coupled to the moving bar 130. The motor body 142 is a connection bracket 112 fixed to the horizontal bar 112 as shown in FIG. It is connected by means of.

In addition, according to the characteristics of the liner motor, in the embodiment, the shaft 144 is driven in a vertical direction, and the moving bar 130 may move vertically along the support rod 110 as the shaft 144 is driven. .

According to the present invention, a measurement assembly 200 is provided on one side of the fixing plate 100. The measurement assembly 200 is a configuration for measuring the weight of a patient, and a load cell 210 for measuring weight, a support plate 220 provided with the load cell 210, and a patient can stand on it. It is configured to include a foot plate 230 provided on the upper surface of the support plate 220.

In addition, a handle 310 is provided in the measurement assembly 200. In the embodiment, the handle 310 is integrally formed with the measurement assembly 200. Therefore, accurate weight measurement is possible when measuring weight. That is, in the conventional weight measuring apparatus with a handle, the handle is provided to be spaced apart from the footrest, and therefore, when the patient climbs on the footrest for weight measurement and grabs the handle, the force may be distributed to the handle, making accurate weight measurement difficult. However, in this embodiment, since the measurement assembly 200 is provided with the handle 310 together, it is possible to accurately measure the patient's weight.

The handle part 310 is formed in a pair on both sides of the support plate 220. The handle 310 has a bar shape, and both ends have a shape that is bent in different directions. That is, the lower end 312 is connected to the support plate 220, and the upper end 314 has a bent shape so that the patient can hold it comfortably. Sensors capable of measuring various body compositions may be built in the upper part 314.

Meanwhile, it has been described above that the present invention provides a first state or a second state according to the driving of the liner motor 140. The first state is a state in which the body weight can be measured, and the second state is a folded state that can be moved/stored. For this purpose, the support plate 220 and the handle part 310 are made to correspond to the first state and the second state. It must have an unfolded and folded state. Let's look at this structure.

A first joint link 410 is connected between the moving bar 130 and the support plate 220, and a second joint link 420 is connected between the support plate 220 and the fixed plate 100. Since the first joint link 410 and the second joint link 420 must be provided on the left/right side of the weight measuring device 10, it is formed in a pair. And the joint links (410, 420) are unfolded or folded according to the vertical movement of the moving bar (130), so that the support plate 220 is brought into contact with the floor (unfolded state) or spaced apart from the floor surface. It is in a vertical position.

In order for the weight measuring device 10 to be in the first state or the second state, the handle part 340 must be folded or unfolded together with the support plate 220.

The lower end 312 of the pair of handles 340 is installed in the guide groove 250 provided in the support plate 220, and when the support plate 220 is erected or unfolded, the lower end 312 is a guide groove ( 250). And in this embodiment, this drive uses a rack gear 242 and a pinion gear 244 as shown in FIG. 6. However, this is only an example, and it is natural that the support plate 220 can be erected or unfolded using a different structure.

In addition, the handle part 340 is coupled to the support plate 220 and an articulated link member 340 therebetween. In this embodiment, the articulated link member 340 is a structure in which two unit links 342 and 344 are connected to each other, and one 342 is coupled with a coupling bracket 316 fitted and fixed to the handle part 310 and , The other 344 is coupled to the support plate 220. In addition, the connection of the unit links 342 and 344 may be applied to any structure in which the unit links 342 and 344 are opened or folded in conjunction with each other.

Each of these unit links 342 and 344 is formed in an approximately flake shape, and the two unit links 342 and 344 are arranged to be shifted in a direction of approximately 90 degrees. The reason for doing this is to change the direction in which the upper end portion 314 of the handle portion 340 faces in the unfolded and folded state of the support plate 220. That is, in the unfolded state, the weight measuring device 10 is directed to the rear (pointing to the right in the drawing) so that the patient can comfortably grip it, and in the folded state, the upper part 314 is inside the weight measuring device 10. It is to face the direction.

According to the present invention, an auxiliary plate 500 is provided on the opposite side of the measurement assembly 200. The auxiliary plate 500 is to cooperate with the support plate 220 to position the weight measuring device 10 more stably. For example, if there is no auxiliary plate 500, the weight measuring device 10 may fall in one direction due to carelessness or the like. Therefore, it will be said that the auxiliary plate 500 serves to stably support the weight measuring device 10.

The auxiliary plate 500 also has an unfolded state and a folded state like the support plate 220. In order to move/storage the weight measuring device 10, the auxiliary plate 500 must be folded as well as the support plate 220 so that it can be easily moved and stored in a narrow space.

The structure for the unfolded or folded state of the auxiliary plate 500 is configured to be symmetrical with the support plate 220 and the joint link provided. That is, a third joint link 510 is connected between the moving bar 130 and the auxiliary plate 500, and a fourth joint link is connected between the auxiliary plate 500 and the fixed plate 100. Further, as the moving bar 130 is unfolded or folded according to the movement in the vertical direction, the auxiliary plate 500 is also in a state in contact with the floor (unfolded state) or in a state that is spaced apart from the floor and erected.

The weight measurement state and non-measurement state of the patient's weight measuring apparatus of the present invention will be described separately.

4A and 4B are views showing a state of the weight measuring apparatus 10 when measuring weight. Looking at this, the support plate 220 and the auxiliary plate 500 are in an unfolded state and in contact with the floor surface, and the movable wheel 101 located on the lower surface of the fixed plate 100 is in a non-contact state with the floor surface. Since the support plate 220 and the auxiliary plate 500 are in an unfolded state, the moving bar 130 is located at the lower end of the support bar 110.

In that state, the patient moves on the footrest 230 and grips the upper end 314 of the handle 300 integrally formed with the measurement assembly 200. Then, the weight is measured in the load cell 210, and at the same time, a body composition detection sensor built in the upper part 314 will detect the body composition of the patient.

The measured weight value or body composition value is transmitted to the input/output device 600. The input/output device 600 displays the received weight value or body composition value on a screen, and selectively transmits it to an external device.

Before the patient moves on the footrest 230, the user can operate the mode setting button provided on the input/output device 600 to measure only one of weight measurement or body composition measurement. If only body composition is measured, it may be measured by grasping the handle 122 provided on the installation bracket 120 according to the patient's condition.

5A and 5B are views showing a state for storing the patient weight measuring device 10. When the weight measurement is completed, the user drives the liner motor 140. The liner motor 140 may be driven by operating the input/output device 600 or a series of buttons provided on the motor body 142.

Then, the motor shaft 144 is moved upward, and the moving bar 130 having one end coupled to the shaft 144 also moves upward along the outer circumferential surface of the support rod 110. Accordingly, according to the movement of the first to fourth joint links (410, 420, 510, 520), it is rotated in the direction of the arrow shown in FIG. 4A, so that the support plate 220 and the auxiliary plate 500 are vertically as shown in the drawing. Place it.

At this time, the support plate 220 is erected or unfolded by the gear movement of the rack gear 242 and pinion gear 244 provided therein. That is, referring to FIG. 6, when the moving bar 130 moves upward according to the driving of the liner motor, the joint links 410 and 420 operate in conjunction, and thus the link 246 connected to the rack gear 242 By rotating in one direction, the rack gear 242 and the pinion gear 244 are driven into engagement with each other, so that the support plate 220 is in an erect or unfolded state.

In this way, the support plate 220 is located on the upper surface of the fixed plate 100, and the support plate 220 does not deviate from the outer direction of the fixed plate 100 as shown in FIG. 5A.

On the other hand, when the support plate 220 and the auxiliary plate 500 are in contact, the handle portion 340 must also be folded. This means that when the first to fourth joint links 410, 420, 510, and 520 are driven, the lower end 312 of the handle part 340 will slide along the guide groove 250 by the driving force. .

Then, the two unit links 342 and 344 connecting the handle 310 and the support plate 220 are also in a state. At this time, since the two unit links 342 and 344 are arranged to be offset in the direction of 90 degrees from each other, the upper part 314 of the handle 310 rotates approximately 90 degrees in the process of folding, and ultimately, the weight measuring device 10 They face each other in the inner direction of.

When the support plate 220 and the auxiliary plate 500 are in a folded state, only the moving wheel 101 is brought into contact with the bottom surface, so that movement is easy. In addition, as shown in FIGS. 5A and 5B, since the lower size of the weight measuring apparatus 100 is folded to a degree slightly larger than the area of the fixed plate 100, it is easy to store even in a very narrow space.

In particular, the weight measuring apparatus 10 of the present invention can be positioned between the beds even if the distance between the beds on which the patient is lying is narrow. That is, the weight measuring apparatus 10 in the second state can enter between the beds, and if the motor 140 is driven in that state, the support plate 220 and the auxiliary plate 500 can be sufficiently spread in the space under the bed. Therefore, it is possible to position the measuring device 10 right next to the bed, it is possible to measure the weight or body composition, etc. while minimizing the moving distance of the patient.

As described above, in the present invention, the mobile patient weight measuring device is in an unfolded state (first state) or a moving/moving/moving/moving state in which the weight can be measured because the moving bar 130 slides along the outer circumferential surface of the support bar 110 according to a predetermined driving force. It can be seen that it provides two structures that transform into a folded state (second state) that can be stored.

Although it has been described with reference to the illustrated embodiments of the present invention as described above, these are only exemplary, and those of ordinary skill in the art to which the present invention pertains, without departing from the spirit and scope of the present invention, various It will be apparent that variations, modifications and other equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
