Abstract
Description
Technical Field
[0001] This utility model relates to the field of clinical weighing technology, and in particular to a weighing device. Background Technology
[0002] In the medical treatment process, accurately obtaining patients' weight information is of paramount importance. Weight data is not only crucial for assessing a patient's physical condition and developing personalized treatment plans (such as medication dosage calculations and nutritional support programs), but also a key indicator for monitoring changes in the patient's condition and evaluating treatment effectiveness. Therefore, accurate measurement of patient weight is an indispensable part of modern medical care.
[0003] However, for some patients who are immobile, bedridden, or critically ill, traditional standing or wheelchair-style weighing methods are often unsuitable. In such cases, medical staff usually need to move the patient from the bed to a specialized weighing device by carrying or transporting them. This process is not only time-consuming and laborious, but also requires the assistance of multiple medical staff, resulting in significant physical exertion for them.
[0004] Frequent patient transport and movement not only increases the workload of medical staff but also increases the risk of unnecessary physical discomfort for patients, and may even lead to secondary injuries such as falls and dislodged tubes, especially for critically ill or postoperative patients. Furthermore, the cumbersome weighing process consumes valuable treatment time, reduces medical efficiency, and places higher demands on human resources. Therefore, how to conveniently, safely, and efficiently determine patient weight during treatment has become a pressing technical problem in the medical field. Utility Model Content

[0006] This utility model provides a weighing device, which includes a load-bearing bracket, a lifting assembly, a hanging scale, and a net. The load-bearing bracket includes a main body that can be covered on a hospital bed and a load-bearing crossbeam located on top of the main body. The lifting assembly is disposed on the main body and is used to drive the load-bearing crossbeam to rise or fall. The hanging scale is disposed on the load-bearing crossbeam. The net is detachably connected to the hook of the hanging scale.
[0007] Optionally, the main body is fitted onto the hospital bed, and the bottom of the main body is equipped with casters; the telescopic end of the lifting assembly is detachably connected to the load-bearing crossbeam; the length direction of the load-bearing crossbeam is parallel or perpendicular to the length direction of the hospital bed.

[0009] Optionally, the lifting assembly includes a first lifting member and a second lifting member. The first lifting member is located at the end of the supporting longitudinal beam away from the base. The telescopic end of the first lifting member is connected to one end of the supporting crossbeam. The second lifting member is rotatably located at the other end of the supporting crossbeam. When the second lifting member is perpendicular to the supporting crossbeam, the telescopic end of the second lifting member contacts the hospital bed.
[0010] Optionally, the lifting assembly further includes a snap-fit block, which is located at the telescopic end of the second lifting component; the snap-fit block has a snap-fit groove adapted to the bed rail.
[0011] Optionally, the main body also includes multiple reinforcing beams, which are evenly distributed around the supporting longitudinal beam; one end of the reinforcing beam is connected to the base, and the other end of the reinforcing beam is connected to the supporting longitudinal beam.
[0012] Optionally, the base has a positioning post at the top; the main body also includes a counterweight block with a positioning hole adapted to the positioning post; the positioning post passes through the positioning hole to achieve a detachable connection between the counterweight block and the base.

[0037] The inventors discovered that obtaining the weight of some patients who are immobile, bedridden, or critically ill is inconvenient in clinical practice. Moving patients for weighing may also increase the workload of medical staff and cause discomfort to patients.
[0038] In view of this, the inventor of this utility model provides a weighing device to solve the above problems. Several specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0039] First Embodiment
[0040] The weighing device mentioned in this embodiment, such as Figure 1As shown, the weighing device includes a load-bearing support, a lifting assembly, a hanging scale 3, and a net 4. The load-bearing support includes a main body 11 and a load-bearing crossbeam 12, with the crossbeam 12 positioned on top of the main body 11. The main body 11 includes multiple sets of first longitudinal beams 111, multiple first crossbeams 112, and multiple reinforcing beams 113. All sets of first longitudinal beams 111 are perpendicular to a first plane. Optionally, the ground can be considered the first plane, or a plane parallel to the ground can be considered the first plane. Each set of first longitudinal beams 111 includes two symmetrically arranged first longitudinal beams 111. The top of one first longitudinal beam 111 is connected to one end of a first crossbeam 112, and the top of the other first longitudinal beam 111 is connected to the other end of the first crossbeam 112. The two first longitudinal beams 111 are located on opposite sides of the bed along its length, and the distance between the two first longitudinal beams 111 is greater than the width of the bed. Multiple sets of first longitudinal beams 111 are arranged at intervals along the length of the bed; for example, two sets of first longitudinal beams 111 are arranged at intervals along the length of the bed. In two adjacent sets of first longitudinal beams 111, the top ends of the two first longitudinal beams 111 located on the same side of the bed are connected by a first transverse beam 112. A reinforcing beam 113 is also provided between a first longitudinal beam 111 and a first transverse beam 112. This reinforcing beam 113 is inclined on the first plane, with one end connected to the first longitudinal beam 111 and the other end connected to the first transverse beam 112. This arrangement completes the installation and connection of the main body 11.
[0041] Optional, such as Figure 1 As shown, each of the first longitudinal beams 111 has a caster wheel 5 at its bottom, which can be regarded as the bottom of the main body 11 having caster wheels 5. This arrangement facilitates the movement of the main body 11.
[0042] Optional, such as Figure 2 As shown, the net bag 4 is rectangular in shape, and each of the four corners of the net bag 4 has a hanging ring 41.
[0043] like Figure 1 , Figure 3 , Figure 4As shown, both of the symmetrically arranged first crossbeams 112 have mounting holes 114 in their middle sections. The lifting assembly includes a first lifting member 21 and a second lifting member 22, which are symmetrically arranged. Specifically, the first lifting member 21 is located in the middle of one of the first crossbeams 112, and its telescopic end passes through the mounting hole 114 of the first crossbeam 112 to the top of the main body 11. The second lifting member 22 is located in the middle of the other first crossbeam 112, and its telescopic end passes through the mounting hole 114 of the first crossbeam 112 to the top of the main body 11. A load-bearing block 13 is provided at the telescopic ends of both the first and second lifting members 21 and 22. The side of the load-bearing block 13 away from the main body 11 has a groove 131. When the first lifting member 21 and the second lifting member 22 are in the retracted state, the load-bearing block 13 contacts the top of the main body 11. The load-bearing crossbeam 12 has a cylindrical rod structure. Both ends of the load-bearing crossbeam 12 are located in the grooves 131 of a load-bearing block 13, which limit the movement of the crossbeam 12. The crossbeam 12 is driven to rise or fall by extending or retracting the telescopic ends of the first lifting member 21 and the second lifting member 22. The fixed ring 31 of the hanging scale 3 is threaded through the load-bearing crossbeam 12, allowing the hanging scale 3 to be mounted on the crossbeam 12. The net bag 4 is used to cover the patient's body. A hanging ring 41 is threaded through the hook 32 of the hanging scale 3, enabling a detachable connection between the net bag 4 and the hanging scale 3.
[0044] Optional, such as Figure 1 , Figure 3 As shown, the length direction of the load-bearing beam 12 is parallel to the length direction of the hospital bed. Or, the length direction of the load-bearing beam 12 is perpendicular to the length direction of the hospital bed.
[0045] The exemplary usage process of the weighing device disclosed in this embodiment is as follows:
[0046] like Figures 1 to 4As shown, medical staff assist the patient to tilt to one side and lay the net bag 4 on the bed. The patient then lies down inside the net bag 4. Next, a fixing ring 31 of the hanging scale 3 is threaded through one end of the load-bearing beam 12. The load-bearing beam 12 is then positioned on top of the main body 11, with both ends of the beam located in the grooves 131 of the two load-bearing blocks 13. The main body 11 is then moved from the foot of the bed to the middle, thus covering the bed. The hanging rings 41 of the net bag 4 are then threaded through the hooks 32. The medical staff plugs the power plugs of the first lifting component 21 and the second lifting component 22 into the sockets at the head of the bed. The medical staff then drive the extension ends of the first lifting component 21 and the second lifting component 22 to the extended state, raising the load-bearing beam 12, the hanging scale 3, and the net bag 4. Once the net bag 4 is off the bed, the hanging scale 3 weighs the patient. After the weighing is completed, the medical staff drive the telescopic ends of the first lifting component 21 and the second lifting component 22 to the retracted state. The load-bearing beam 12, the hanging scale 3, and the net bag 4 are lowered accordingly. When the net bag 4 is on the hospital bed, the medical staff remove the net bag 4 from the hanging scale 3 and move the main body 11 away from the hospital bed. The medical staff then assist the patient to get out of the net bag 4 and remove the net bag 4.
[0047] Compared to existing technologies, in this embodiment, even when weighing patients who are immobile, bedridden, or critically ill, the patient only needs to turn sideways on the bed to enter the net bag 4. The moving main body 11 is then placed over the bed, and the net bag 4 is secured using the hooks 32 of the hanging scale 3. The lifting assembly then raises the load-bearing beam 12, allowing the patient inside the net bag 4 to be weighed. This eliminates the need to move the patient, reducing the workload of medical staff and minimizing patient discomfort.
[0048] Second Embodiment
[0049] This embodiment also proposes a weighing device. The second embodiment differs from the first embodiment in the structure of the main body 11 and the arrangement of the lifting components, specifically as follows:
[0050] like Figures 5 to 7As shown, the main body 11 includes a base 14, a supporting longitudinal beam 15, and a supporting transverse beam 16. Optionally, the bottom of the base 14 is provided with multiple casters 5 to facilitate the movement of the main body 11. The bottom end of the supporting longitudinal beam 15 is located at the top of the base 14, and the supporting longitudinal beam 15 is perpendicular to the top of the base 14. The top of the supporting longitudinal beam 15 has a receiving groove 151, and a first lifting member 21 is disposed in the receiving groove 151, with the telescopic end of the first lifting member 21 connected to one end of the supporting transverse beam 16. The main body of the second lifting member 22 is hinged to the other end of the supporting transverse beam 16. The second lifting member 22 can rotate around the other end of the supporting transverse beam 16. When the second lifting member 22 is perpendicular to the supporting transverse beam 16, the telescopic end of the second lifting member 22 abuts against the headboard of the hospital bed. The side of the supporting beam 16 facing the hospital bed is the bottom of the supporting beam 16. The bottom of the supporting beam 16 has two oppositely arranged positioning blocks 17. Each of the two positioning blocks 17 has a through hole 171, through hole 171 for the load-bearing beam 12 to pass through.
[0051] The exemplary usage process of the weighing device disclosed in this embodiment is as follows:
[0052] like Figure 2 , Figures 5 to 7 As shown, the main body 11 is moved to the bedside, so that the base 14 enters the bed from the foot of the bed and the supporting longitudinal beam 15 contacts the foot rail. The second lifting component 22 is rotated, and the telescopic end of the second lifting component 22 is extended and abuts against the head rail. Then, the fixing ring 31 of the hanging scale 3 is inserted through one end of the load-bearing crossbeam 12, and the two ends of the load-bearing crossbeam 12 are respectively inserted through the through holes 171 of the two positioning blocks 17, so that the two ends of the load-bearing crossbeam 12 are respectively located in the through holes 171 of the two positioning blocks 17. Then, the medical staff assists the patient to tilt to one side and lays the net bag 4 on the bed, and then assists the medical staff to lie in the net bag 4. Then, the hooks 32 of the hanging scale 3 are sequentially inserted through the multiple hanging rings 41 of the net bag 4. The medical staff plugs the power plugs of the first lifting component 21 and the second lifting component 22 into the socket at the head of the bed. Medical staff drive the telescopic end of the first lifting component 21 to the extended state, and the telescopic end of the second lifting component 22 continues to extend, causing the load-bearing beam 12, the hanging scale 3, and the net bag 4 to rise accordingly. After the net bag 4 leaves the bed, the hanging scale 3 weighs the patient. After weighing, medical staff drive the telescopic ends of the first lifting component 21 and the second lifting component 22 to the retracted state, causing the load-bearing beam 12, the hanging scale 3, and the net bag 4 to lower accordingly. When the net bag 4 is on the bed, medical staff remove the net bag 4 from the hanging scale 3 and assist the patient to get out of the net bag 4, then remove the net bag 4. The telescopic end of the second lifting component 22 is then further retracted, and the second lifting component 22 is rotated to the top of the load-bearing beam 12. Finally, the main body 11 is moved away from the bed.
[0053] Compared to existing technologies, in this embodiment, the weighing device features a sophisticated structural design, occupies a small space, and utilizes the cooperation between the bed and the weighing device to further increase its weight. The patient is weighed using support at both the head and foot of the bed. The supporting beam 16 is positioned parallel to the length of the bed, freeing up space on both sides of the bed to facilitate medical staff assisting the patient with weighing from both sides.
[0054] Third Embodiment
[0055] This embodiment also proposes a weighing device. The third embodiment is a further improvement based on the second embodiment, with the main improvement being:
[0056] Optional, such as Figure 8 As shown, the top of the base 14 has two symmetrically arranged positioning posts 141. The main body 11 also includes multiple counterweights 142, each counterweight 142 having two positioning holes 143 that are adapted to the positioning posts 141. By passing the positioning posts 141 through the positioning holes 143, the counterweights 142 are detachably connected to the base 14. Medical staff can flexibly configure the number of counterweights 142 to further increase the weight of the base 14. This arrangement can prevent the load-bearing beam 12 from tilting towards the head of the bed when the patient is weighed.
[0057] Optional, such as Figure 5 , Figure 8 As shown, the main body 11 also includes multiple reinforcing beams 113, which are evenly distributed around the supporting longitudinal beam 15, with adjacent reinforcing beams 113 arranged perpendicularly to each other. The reinforcing beams 113 are inclinedly positioned on the base 14, with one end connected to the bottom of the base 14 and the other end connected to the supporting longitudinal beam 15. This arrangement enhances the structural strength between the supporting longitudinal beam 15 and the base 14.
[0058] Optional, such as Figure 5 , Figure 8 , Figure 9As shown, the main body 11 also includes two limiting members 18, which are respectively disposed on both sides of the base 14 along its length. The two limiting members 18 are symmetrical to each other. Since the two limiting members 18 are symmetrical to each other, the connection between one limiting member 18 and the base 14 is described as an example. One end of the limiting member 18 has a hinge hole 181, and the other end of the limiting member 18 has a limiting groove 182, which is adapted to the bed leg. The base 14 has two hinge protrusions 144, which are located on one side of the base 14 and are arranged opposite to each other. There is a sandwich 145 between the two hinge protrusions 144 to accommodate the limiting member 18. Both hinge protrusions 144 have hinge holes 181. One end of the limiting member 18 with a hinge hole 181 is placed inside the interlayer 145, and the hinge hole 181 of the limiting member 18 is aligned with the hinge holes 181 of the two hinge protrusions 144. A hinge shaft 146 is then used to pass through multiple hinge holes 181 sequentially, thus completing the hinge connection of the limiting member 18 to the base 14. During the use of the weighing device of this invention, the main body 11 is moved to the bed, allowing the base 14 to enter the bed floor from the foot of the bed, and the supporting longitudinal beam 15 to contact the foot rail. Then, the limiting member 18 is rotated so that the bed legs are positioned within the limiting groove 182, thus limiting the main body 11 and strengthening the connection between the bed and the weighing device. This further increases the weight of the weighing device, and the patient is weighed using a two-end support method. This configuration increases the stability of the weighing device when weighing the patient. Subsequent usage is the same as in the second embodiment.
[0059] Optional, such as Figure 7 , Figure 10 As shown, the supporting crossbeam 16 has a notch 161 at the end away from the supporting longitudinal beam 15. The top of the supporting crossbeam 16 has two opposing hinge protrusions 144, located at the top of the supporting crossbeam 16. The interlayer 145 between the two hinge protrusions 144 communicates with the notch 161. The main body of the second lifting member 22 is placed within the interlayer 145, and a hinge shaft 146 is sequentially passed through the hinge holes 181 of the hinge protrusions 144 and the hinge holes 181 of the second lifting member 22. This completes the hinge connection of the second lifting member 22 to the supporting crossbeam 16.
[0060] Optional, such as Figure 7 , Figure 10As shown, based on the above technical solution, the end of the supporting crossbeam 16 away from the supporting longitudinal beam 15 has a limiting hole 162 that penetrates the notch 161. The main body 11 also includes a limiting plate 163 adapted to the limiting hole 162. In use, the second lifting member 22 is rotated so that it is located within the notch 161 and is perpendicular to the supporting crossbeam 16. Then, the limiting plate 163 is sequentially inserted through the limiting holes 162 to limit the supporting crossbeam 16 located within the notch 161. This arrangement increases the stability of the second lifting member 22 when weighing the patient.
[0061] Optional, such as Figure 5 , Figure 7 As shown, based on the above technical solution, the lifting assembly also includes a locking block 23. The locking block 23 has a locking groove 24 adapted to the headboard of the hospital bed, and the locking groove 24 is disposed at the telescopic end of the second lifting member 22. After the second lifting member 22 is rotated, the locking block 23 extends along with the telescopic end of the second lifting member 22, and the headboard abuts against the bottom of the locking groove 24. This can further increase the stability of the second lifting member 22 when weighing the patient.
[0062] Optional, such as Figure 5 , Figure 6 , Figure 8 As shown, the main body 11 also includes an auxiliary support beam 19, which is inclinedly disposed on the first plane. One end of the auxiliary support beam 19 is fixedly connected to one end of the support longitudinal beam 15. When the first lifting member 21 is in its original state, the bottom of the support crossbeam 16 contacts the top of the support longitudinal beam 15 and also contacts the other end of the auxiliary support beam 19. In this technical solution, the auxiliary support beam 19 further supports the support crossbeam 16, increasing the stability of the support crossbeam 16.
[0063] Optional, such as Figure 5 , Figure 8 As shown, the weighing device also includes a protective sleeve 6, which is made of silicone or rubber. The protective sleeve 6 has a receiving cavity 61, and a slit 62 communicating with the receiving cavity 61 is provided on the protective sleeve 6. When the side of the protective sleeve 6 with the slit 62 is aligned with the supporting longitudinal beam 15, the supporting longitudinal beam 15 will enter the receiving cavity 61 through the slit 62, thus completing the installation of the protective sleeve 6 onto the supporting longitudinal beam 15. Optionally, the protective sleeve 6 is located in the middle of the supporting longitudinal beam 15, which facilitates the movement of the main body 11 by medical personnel through the protective sleeve 6.
