Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a two-way pull-out treatment vehicle. Background Art

[0002] The treatment cart is a commonly used device for clinical nurses in operation. It can transport cotton swabs, adhesive tape, syringes, needles, blood collection tubes, gloves, disinfectants and other items required for nurses' daily work, making it convenient for nurses to go back and forth between various wards to provide treatment and nursing for patients. The traditional treatment cart is composed of two upper and lower countertops and four legs with rollers, and guardrails are set on the periphery of the upper and lower countertops. However, the problem with this is that various items are placed on the upper and lower countertops in disorder, which increases the risk of contamination, and the items placed on the lower countertop are affected by the upper countertop, making it inconvenient to take, which brings inconvenience to nursing and treatment work. Therefore, the improved treatment cart transforms the lower countertop into a drawer, and sets a partition in the drawer to divide the internal space of the drawer into multiple storage compartments for items, so that cotton swabs, adhesive tape, syringes, needles, blood collection tubes and other items can be placed in categories, reducing the risk of contamination and making it convenient for nurses to take them.

[0003] However, the drawer of the improved treatment cart can often only be pulled out in one direction. During rescue, if the medical staff happens not to stand on the side of the treatment cart where the drawer can be pulled out, the treatment cart needs to be turned or the medical staff needs to change their standing position, which will waste precious rescue time and is not conducive to rescue. Therefore, it is necessary to improve the structure of the drawer-type treatment cart. Summary of the invention

[0004] The present invention is intended to provide a two-way drawable treatment cart to solve the problem that the drawer of the existing treatment cart can only be drawn out in one direction.

[0005] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a two-way pull-out treatment cart, including a treatment cart body, a drawer box is provided on the treatment cart body, the drawer box is a hollow rectangular structure without front side and rear side, a drawer is horizontally slidably connected in the drawer box, the front side wall and the rear side wall of the drawer can slide into the drawer box, and a locking assembly is provided on the front side wall and the rear side wall of the drawer, the locking assembly includes a fixed block and a lock column, the fixed block is fixedly connected to the side wall of the drawer, a cavity is opened in the fixed block, the lock column is horizontally slidably connected in the cavity, and one end of the lock column is located outside the cavity, and the other end is located in the cavity, the end of the lock column located outside the cavity can be against the outer wall of the drawer box, an electromagnet and an elastic member for resetting the lock column are provided in the cavity, the electromagnet is magnetically adsorbed when energized, the locking assembly also includes a switch for controlling the on and off of the electromagnet, and the switch in the locking assembly on the front side wall of the drawer is located on the rear side wall of the drawer, and the switch in the locking assembly on the rear side wall of the drawer is located on the front side wall of the drawer.

[0006] The working principle and beneficial effects of this solution are as follows: in this solution, the drawer can be drawn out in both directions, which is convenient for medical staff to use. During rescue, there is no need to turn the treatment cart, nor is there a need for medical staff to change their position to draw the drawer, thereby avoiding wasting precious rescue time. In addition, in this solution, the drawer is locked by a locking assembly to prevent the drawer from being opened when not in use, thereby effectively preventing the items in the drawer from being contaminated, and the lock column in the locking assembly is separated from the outer wall of the drawer box under the magnetic adsorption of the electromagnet, so that the drawer can be drawn out from a direction away from the lock column, and the switch that controls the on and off of the electromagnet is on the front side wall or the rear side wall of the drawer, which is convenient for medical staff to press, and the operation is convenient and fast, and will not affect the speed of medical staff to draw the drawer, thereby avoiding wasting precious rescue time.

[0007] Optionally, a first universal ball is provided at one end of the locking column located outside the cavity.

[0008] In this solution, when the switch is closed, the lock column retracts into the cavity part in the direction of the electromagnet under the magnetic adsorption of the electromagnet. When the medical staff pulls out the drawer and takes out the items in the drawer, the switch will be disconnected, the electromagnet will be powered off, the lock column will be reset under the action of the elastic member, and the first universal ball will be against the inner wall of the drawer box. In this way, when the medical staff closes the drawer, there is no need to press the switch, but to directly push the drawer back. In this process, the first universal ball and the inner wall of the drawer box are rolling friction, the friction is small, and the lock column and the drawer box will not be damaged.

[0009] Optionally, push-pull handles are provided on the front side wall and the rear side wall of the drawer, and the switch is installed on the push-pull handles.

[0010] In this solution, the switch is on the push-pull handle, so that when the medical staff holds the push-pull handle, they can press the switch to energize the electromagnet.

[0011] Optionally, the middle section of the cavity expands to form an additional chamber, the end of the lock column facing the electromagnet is located in the additional chamber, and the end of the lock column located in the additional chamber is fixedly connected to a connecting plate, one end of the elastic member is connected to the connecting plate, and the other end of the elastic member is connected to the inner wall of the additional chamber.

[0012] In this solution, the elastic member is connected to the connecting plate and the inner side wall of the additional chamber, so as to realize the reset of the connecting plate and the lock column. Compared with the method in which the elastic member is connected to the lock column and the inner side wall of the cavity, this solution can reduce the length of the elastic member.

[0013] Optionally, the number of locking components on the front side wall and the rear side wall of the drawer is two groups, and the two groups of locking components are distributed at the left and right ends of the drawer.

[0014] In this solution, two sets of locking components are distributed at the left and right ends of the drawer, thereby locking the left and right ends of the drawer and balancing the force on the drawer.

[0015] Optionally, a first slide groove and a second slide groove are provided on the inner wall of the drawer box, and the first slide groove and the second slide groove both have a closed end and an open end, and the closed end of the first slide groove and the open end of the second slide groove are located on the same side; a first slider and a second slider are fixedly connected to the outer wall of the drawer, the first slider is slidably connected to the first slide groove, and the second slider is slidably connected to the second slide groove, and the first slider is initially located at the open end of the first slide groove, and the second slider is initially located at the open end of the second slide groove.

[0016] In this solution, when the medical staff pulls out the drawer, the first slider slides from the open end of the first slide groove to the closed end, and the second slider disengages from the second slide groove from the open end. When the first slider slides to the closed end of the first slide groove, the drawer can no longer be pulled out; similarly, when the medical staff pulls out the drawer in the opposite direction, the second slider slides from the open end of the second slide groove to the closed end, and the first slider disengages from the first slide groove from the open end. When the second slider slides to the closed end of the second slide groove, the drawer can no longer be pulled out, thereby preventing the drawer from detaching from the drawer box.

[0017] Optionally, the number of the first sliding grooves and the second sliding grooves are both more than two, and the more than two first sliding grooves are distributed on the left inner wall and the right inner wall of the drawer box or on the inner bottom wall of the drawer box, and the more than two second sliding grooves are distributed on the left inner wall and the right inner wall of the drawer box or on the inner bottom wall of the drawer box.

[0018] In this solution, more than two first sliding grooves and second sliding grooves are designed to balance the restrictive force applied to the drawer when it is pulled out.

[0019] Optionally, a third slide groove is provided on the inner bottom wall of the drawer box, and a plurality of second universal ball bearings are fixedly installed in the third slide groove. A slide bar is provided on the outer bottom wall of the drawer, and the bottom surface of the slide bar abuts against the second universal ball bearings.

[0020] In this solution, there is rolling friction between the slide bar and the second universal ball, thereby reducing the resistance encountered during the drawer withdrawal process, making it easier for medical staff to pull out the drawer.

[0021] Optionally, a partition plate is provided in the drawer, and the partition plate divides the internal space of the drawer into a plurality of storage cavities.

[0022] In this solution, a partition plate is used to divide the inner space of the drawer into several storage cavities so as to classify and place items.

[0023] Optionally, a plurality of universal wheels are fixedly mounted on the bottom end of the treatment vehicle body.

[0024] In this solution, the design of universal wheels makes it easier for medical staff to move the treatment vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] This embodiment is basically Figure 1 and Figure 2 As shown: a two-way pull-out treatment cart, comprising a treatment cart body 1, on which a drawer box 2 is arranged. In this embodiment, there are two drawer boxes 2, which are arranged vertically along the treatment cart body 1; the drawer box 2 is a hollow rectangular parallelepiped structure without a front side and a rear side, and a drawer 3 is horizontally slidably connected in the drawer box 2, and the front side wall and the rear side wall of the drawer 3 can slide into the drawer box 2. Locking components are arranged on the front side wall and the rear side wall of the drawer 3. In this embodiment, there are two sets of locking components on the front side wall and the rear side wall of the drawer 3, and the two sets of locking components are distributed at the left and right ends of the drawer 3.

[0035] Each locking assembly includes a fixing block 4 and a locking column 5. The fixing block 4 is fixedly connected to the side wall of the drawer 3. Figure 3 As shown, a cavity 401 is provided in the fixed block 4, and the lock column 5 is horizontally slidably connected in the cavity 401, and one end of the lock column 5 is located outside the cavity 401, and the other end is located inside the cavity 401. The end of the lock column 5 located outside the cavity 401 can abut against the outer wall of the drawer box 2, and the end of the lock column 5 located outside the cavity 401 is fixedly connected with a first universal ball 6. An electromagnet 7 and an elastic member 8 for resetting the lock column 5 are provided in the cavity 401. After the electromagnet 7 is energized, the lock column 5 is magnetically attracted. The left end of the elastic member 8 is fixedly connected to one end of the lock column 5 located in the cavity 401, and the right end of the elastic member 8 is fixedly connected to the right inner wall of the cavity 401. In this embodiment, the elastic member 8 is a spring, and the number is two. The locking assembly also includes a switch 9 for controlling the on and off of power to the electromagnet 7, and the switch 9 in the locking assembly on the front side wall of the drawer 3 is located on the rear side wall of the drawer 3, and the switch 9 in the locking assembly on the rear side wall of the drawer 3 is located on the front side wall of the drawer 3. Specifically, a push-pull handle 10 is provided on the front and rear side walls of the drawer 3, and the switch 9 is fixedly mounted on the push-pull handle 10.

[0036] Combination Figure 4 and Figure 5 As shown, the inner wall of the drawer box 2 is provided with a first slide groove 11 and a second slide groove 12, and the first slide groove 11 and the second slide groove 12 both have a closed end and an open end, and the closed end of the first slide groove 11 and the open end of the second slide groove 12 are located on the same side (in this embodiment, the closed end of the first slide groove 11 is located at the front side of the drawer box 2, and the open end of the second slide groove 12 is located at the front side of the drawer box 2). The number of the first slide groove 11 and the second slide groove 12 is more than two, and the more than two first slide grooves 11 are distributed on the left inner wall and the right inner wall of the drawer box 2 or on the inner bottom wall of the drawer box 2, and the more than two second slide grooves 12 are distributed on the left inner wall and the right inner wall of the drawer box 2 or on the inner bottom wall of the drawer box 2; in this embodiment, the number of the first slide groove 11 and the second slide groove 12 is two, and the two first slide grooves 11 are distributed on the left inner wall and the right inner wall of the drawer box 2, and the two second slide grooves 12 are distributed on the left inner wall and the right inner wall of the drawer box 2. A first slider 13 and a second slider 14 are fixedly connected to the outer wall of the drawer 3. The first slider 13 is slidably connected to the first slide groove 11, and the second slider 14 is slidably connected to the second slide groove 12. The first slider 13 is initially located at the open end of the first slide groove 11, and the second slider 14 is initially located at the open end of the second slide groove 12.

[0037] Combination Figure 3As shown, a third slide groove 15 is opened on the inner bottom wall of the drawer box 2, and a plurality of second universal ball bearings 16 are fixedly installed in the third slide groove 15. A slide bar 17 is integrally formed on the outer bottom wall of the drawer 3, and the bottom surface of the slide bar 17 is against the second universal ball bearings 16. The rolling friction between the slide bar 17 and the second universal ball bearings 16 is utilized to reduce the resistance encountered when the drawer 3 slides relative to the drawer box 2, so that medical staff can push and pull the drawer 3 conveniently.

[0038] A partition plate 18 is provided inside the drawer 3, and the partition plate 18 divides the internal space of the drawer 3 into a plurality of storage chambers 310, so that various items can be stored in a classified manner, thereby facilitating the medical staff to take out the items. A plurality of universal wheels 19 are fixedly installed at the bottom end of the treatment cart body 1. In this embodiment, the number of universal wheels 19 is four, and the four universal wheels 19 are distributed at the four corners of the bottom end of the treatment cart body 1, so that the medical staff can push it to move.

[0039] When in use, the nurse holds the push-pull handle 10 on the front wall of the drawer 3 and presses the switch 9 on the push-pull handle 10 with the thumb. Since the nurse presses the switch 9 on the front wall of the drawer 3 at this time, the electromagnet 7 in the locking assembly on the rear wall of the drawer 3 electromagnetically absorbs the lock column 5, so that the lock column 5 overcomes the elastic force of the elastic member 8 and slides toward the electromagnet 7, and the lock column 5 and the first universal ball 6 retreat toward the cavity 401, and the lock column 5 and the first universal ball 6 are separated from the rear wall of the drawer box 2, so that the drawer 3 is unlocked, and the nurse pulls out the drawer 3, and the rear wall of the drawer 3 enters the drawer box 2, and the items in the drawer 3 are exposed for the nurse to take.

[0040] During the above process, when the drawer 3 slides outward, the slide bar 17 slides on the second universal ball bearing 16, and the drawer 3 is subject to little resistance, so the nurse can easily pull out the drawer 3. At the same time, the first slider 13 slides from the open end to the closed end in the first slide groove 11, and the second slider 14 detaches from the second slide groove 12 from the open end. When the first slider 13 slides to the closed end of the first slide groove 11, the drawer 3 can no longer be pulled out, ensuring that the drawer 3 will not detach from the drawer box 2, so that the nurse can take the items and push the drawer 3 back inward.

[0041] In addition, the nurse does not need to continuously press the switch 9 when pulling out the drawer 3. After the drawer 3 slides outward a certain distance, the nurse no longer presses the switch 9, and the switch 9 is disconnected. The electromagnet 7 is powered off and no longer applies magnetic adsorption force to the lock column 5. Under the action of the elastic member 8, the lock column 5 tends to slide away from the electromagnet 7. The first universal ball 6 presses against the inner wall of the drawer box 2, and rolling friction occurs between the first universal ball 6 and the inner wall of the drawer box 2, with small friction resistance.

[0042] After taking out the items, the nurse pushes the drawer 3 back inwards. During this process, rolling friction occurs between the first universal ball 6 and the inner wall of the drawer box 2. The friction resistance is small. After the first universal ball 6 on the rear wall of the drawer 3 is separated from the inner wall of the drawer box 2, the lock column 5 slides away from the electromagnet 7 under the action of the elastic member 8, and the lock column 5 and the first universal ball 6 are reset, thereby restoring the locking function of the drawer 3 to prevent the drawer 3 from sliding. At the same time, the first slider 13 and the second slider 14 are reset.

[0043] Similarly, if the nurse holds the push-pull handle 10 on the rear wall of the drawer 3 and presses the switch 9 on the push-pull handle 10, the lock column 5 and the first universal ball 6 in the locking assembly on the front wall of the drawer 3 will retract toward the direction of the cavity 401 under the magnetic adsorption of the electromagnet 7, and the lock column 5 and the first universal ball 6 will be separated from the front wall of the drawer box 2, so that the drawer 3 can be unlocked, so that the nurse can pull out the drawer 3 (at this time, the front wall of the drawer 3 enters the drawer box 2); during this process, the second slider 14 slides from the open end to the closed end in the second slide groove 12, and the first slider 13 is separated from the first slide groove 11 from the open end. When the second slider 14 slides to the closed end of the second slide groove 12, the drawer 3 can no longer be pulled out, ensuring that the drawer 3 will not be separated from the drawer box 2. After the items are taken, the nurse can push the drawer 3 back inward.

[0044] In summary, in this embodiment, the drawer 3 on the treatment cart body 1 can be drawn out in both directions, which is convenient for medical staff to use. During rescue, there is no need to turn the treatment cart, nor is there any need for medical staff to change their position to draw out the drawer 3, thereby avoiding wasting precious rescue time. In addition, the drawer 3 in this embodiment is locked by a locking assembly to prevent the drawer 3 from being opened when not in use, thereby effectively preventing the items in the drawer 3 from being contaminated. In addition, in this embodiment, the first slider 13 and the second slider 14 are also used to prevent the drawer 3 from sliding out of the drawer box 2.

[0045] Embodiment 2

[0046] The difference between this embodiment and the first embodiment is that: Figure 6 As shown, in this embodiment, the middle section of the cavity 401 expands to form an additional chamber 402, one end of the lock post 5 facing the electromagnet 7 is located in the additional chamber 402, and one end of the lock post 5 located in the additional chamber 402 is fixedly connected to the connecting plate 20, one end of the elastic member 8 is connected to the connecting plate 20, and the other end of the elastic member 8 is connected to the inner wall of the additional chamber 402. In addition, the electromagnet 7 can magnetically adsorb the connecting plate 20 after being energized.

[0047] In this embodiment, the elastic member 8 is located in the additional chamber 402, and the elastic member 8 is shortened by force during the sliding process of the lock column 5 toward the electromagnet 7; after the lock column 5 and the first universal ball 6 are separated from the inner wall of the drawer box 2, the lock column 5 slides away from the electromagnet 7 under the action of the elastic member 8, thereby realizing the reset of the lock column 5 and the first universal ball 6, and restoring the locking function of the drawer 3. Moreover, compared with the first embodiment, the length of the elastic member 8 in this embodiment is effectively reduced.
