Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nursing bed for replacing PICC lines. Background Technology

[0002] A PICC (Peripherally Inserted Central Catheter) is inserted through a peripheral vein in the arm (basilicone vein, median cubital vein, cephalic vein), then follows the course of the blood vessels through the axillary vein, subclavian vein, and brachiocephalic vein, finally inserting the catheter tip into the superior vena cava. PICCs provide patients with a convenient, safe, effective, and long-term venous access and are widely used in clinical practice.

[0003] The PICC line must be dressed within the first 24 hours. Afterward, if the wound heals well and there is no infection or bleeding, the dressing should be changed every 7 days. Currently, when changing the PICC, the patient is usually laid on a hospital bed, and the limb requiring PICC replacement is supported by a movable cart. Medical staff perform the procedure on the surface of the cart. However, because the bed and the support structure are two separate entities, they take up extra space when not in use and are inconvenient to store. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing PICC replacement methods require additional support structures, and these support structures are independent of the nursing bed, occupying a large space and being inconvenient to store. To address this problem, this invention proposes a nursing bed for PICC replacement, comprising: a bed body, a bed board, a mattress, a lifting mechanism, and a support assembly. The bed board is mounted on the bed body, and the mattress is mounted on the bed board. The bed board is three-sectioned, with the two side sections hinged to the middle section. Two lifting mechanisms are provided and respectively located below the bed body, connected to the lower surfaces of the two side sections of the bed board. The support assembly is slidably connected to one side of the bed body and is extendable, with the sliding direction of the support assembly opposite to the extension direction.

[0005] In this embodiment, the technical solution includes a support component that slides along the bed body for easy adjustment and support of the patient's limbs. The support component itself is also extendable, reducing space occupation. A lifting mechanism adjusts the height of the bed board, significantly improving patient comfort. Furthermore, the three-section bed board allows for adjustment of both sides, enabling the limb requiring PICC replacement to be positioned on the side of the support component simply by adjusting the patient's lying position, facilitating the PICC replacement procedure.

[0006] In a preferred embodiment of the present invention, the four legs of the bed body are height-adjustable, and the legs can be adjusted according to the height of medical staff to facilitate the replacement of PICC lines for patients.

[0007] In a preferred embodiment of the present invention, a movable groove for a lifting component is provided on one side of the bed frame of the bed body, which facilitates the sliding of the lifting component.

[0008] In a preferred embodiment of the present invention, the movable groove is a through groove that extends through both the inner and outer surfaces of the bed frame. The direction of the movable groove is consistent with the extension and retraction direction of the lifting component. The lifting component can extend and retract freely and can be stored inside the bed body when not in use, without taking up additional space.

[0009] In a preferred embodiment of the present invention, the inner surface of the bed frame where the movable slot is located is provided with a slide rail for the lifting component. The slide rail is used to allow the lifting component to slide, making it easy to move to a suitable position to lift the patient's limbs and complete the PICC replacement operation.

[0010] In a preferred embodiment of the present invention, the lifting mechanism includes a support base, an electric push rod, a first fixing part, and a second fixing part. The support base is connected to the bed legs, the first fixing part is mounted on the support base, the fixed end of the electric push rod is hinged to the first fixing part, the movable end of the electric push rod is hinged to the second fixing part, and the second fixing part is connected to the lower surface of the bed board. By extending and retracting the push rod, the bed board can be lifted, allowing the patient to lie in a comfortable position.

[0011] In a preferred embodiment of the present invention, the lifting assembly includes a lifting plate, a limiting block, a slider, a guide rod, and a support leg. The lifting plate passes through a moving groove. A limiting block is provided at the bottom inner side of the lifting plate. The slider is slidably connected to a slide rail. A guide rod is provided on the inner surface of the slider. The guide rod passes through and extends out of the limiting block. A support leg is provided at the bottom end of the lifting plate. The lifting plate is used to place the limb of the patient that needs PICC replacement, so as to facilitate the operation by medical staff. The slider cooperates with the slide rail to realize the sliding of the lifting assembly. The guiding direction of the guide rod is the extension and retraction direction of the lifting assembly.

[0012] In a preferred embodiment of the present invention, the sum of the thicknesses of the lifting plate and the limiting block is greater than the height of the moving groove. Due to the obstruction of the limiting block, the lifting component will not completely detach during extension and retraction.

[0013] In a preferred embodiment of the present invention, a handle is provided on the outer side wall of the lifting plate, which facilitates manual extension and retraction of the lifting component.

[0014] In a preferred embodiment of the present invention, the support leg is located outside the bed frame of the bed body, the height of the support leg is adjustable, the support leg assists in supporting the lifting component, and the height of the support leg is adjusted according to the height of the bed leg.

[0015] The advantages of this utility model compared with the prior art are:

[0016] The technical solution of this utility model, by setting up a support component, can slide along the bed body, making it easy to adjust and then support the patient's limbs. The support component itself can also extend and retract, reducing the space occupied. By setting up a lifting mechanism, the height of the bed board can be adjusted, greatly improving the patient's comfort when lying down. At the same time, with the three-section bed board, both sides of the bed board can be adjusted. By simply adjusting the patient's lying direction, the limb that needs to be replaced with the PICC is located on the side where the support component is located, making it easy to complete the PICC replacement operation.

Detailed Implementation

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model will be described in detail below. Example 1

[0024] like Figure 1-5 As shown, this utility model is a nursing bed for replacing PICC, including: a bed body 1, a bed board 2, a mattress 3, a lifting mechanism 4, and a support assembly 5.

[0025] like Figure 1 Figure 2 Figure 3 As shown, the bed body 1 is placed on the ground via four bed legs 11. The height of the bed legs 11 is adjustable, so the height of the bed body 1 is adjustable. In actual use, it can be adjusted according to the height of the relevant medical staff to facilitate the medical staff in replacing the PICC.

[0026] Furthermore, the four bed legs 11 can be equipped with electric push rods, and the four bed legs 11 can extend and retract synchronously, with the extension and retraction ends of the electric push rods connected to the bed body 1.

[0027] In this embodiment, a movable groove 12 is provided on one side of the bed frame of the bed body 1. The movable groove 12 extends through the inner and outer surfaces of the bed frame. The two ends of the movable groove 12 extend towards the head and foot of the bed, respectively. The lifting component 5 slides in the movable groove 12 and moves to a suitable position to support the patient's limbs, so that medical staff can complete the PICC replacement operation.

[0028] In this embodiment, a slide rail 13 is installed on the inner surface of the bed frame where the moving groove 12 is located. The slide rail 13 is used to cooperate with the lifting component 5 to realize the sliding of the lifting component 13. The slide rail 13 belongs to the prior art.

[0029] like Figure 3 As shown, the bed board 2 is located above the bed body 1 and is used to support the mattress 3. The bed board 2 is in the form of three sections, with both side sections of the bed board 2 being hinged to the middle section. Therefore, the side sections of the bed board 2 can rotate and be raised around the hinge point to facilitate the patient's adjustment of their lying position and improve comfort.

[0030] In this embodiment, the mattress 3 is located above the bed board 2. The mattress 3 is also divided into three sections. The specifications and dimensions of each section of the mattress 3 are the same as those of each section of the bed board 2 that are in contact with it. After the mattress 3 is divided into sections, it is easy to move together with the bed board 2 as it rotates and rises. Furthermore, the mattress 3 is also easy to fold and transport after being divided into sections, which is the prior art.

[0031] In this embodiment, there are two lifting mechanisms 4, which are installed under the head and foot of the bed body 1 respectively. The lifting mechanisms 4 are connected to the two side sections of the bed board 2, and the bed board 2 can be rotated and lifted through the lifting mechanisms.

[0032] like Figure 3 As shown, the lifting mechanism 4 includes a support base 41, an electric actuator 42, a first fixing part 43, and a second fixing part 44. The support base 41 is elongated, and its two ends are respectively connected to a set of bed legs 11 near the head or foot of the bed. The support base 41 is connected to the telescopic ends of the bed legs 11. Therefore, when the height of the bed legs 11 is adjusted, it will not affect the lifting mechanism 4.

[0033] In this embodiment, the fixed end of the electric actuator 42 is hinged to the first fixed part 43, and the movable end of the electric actuator 42 is hinged to the second fixed part 44. The first fixed part 43 is fixedly installed on the support base 41, and the second fixed part 44 is fixedly installed on the lower surface of the bed board 2.

[0034] like Figure 4 and Figure 5 As shown, the lifting assembly 5 is slidably connected to one side of the bed body 1. The lifting assembly 5 itself can extend and retract. The lifting assembly 5 includes a lifting plate 51, a limiting block 52, a slider 53, a guide rod 54, and a support leg 55.

[0035] In this embodiment, the lifting plate 51 passes through the moving groove 12, and the inner side of the lifting plate 51 is located inside the bed body 1. The bottom end of the inner side of the lifting plate 51 protrudes downward to form a limiting block 52. The sum of the thickness of the lifting plate 51 and the limiting block 52 is greater than the height of the moving groove 12, so the lifting plate 51 will not come out of the moving groove 12.

[0036] In this embodiment, the slider 53 is matched with the slide rail 13, and the slider 53 can slide on the slide rail 13, which is the prior art. A guide rod 54 is installed on the inner surface of the slider 53. The guide rod 54 passes through and extends out of the limiting block 52, and the lifting plate 51 can slide in the extension direction of the guide rod 54.

[0037] Furthermore, the guide rod 54 is perpendicular to the slider 53, so the extension and retraction direction of the lifting plate 51 is perpendicular to the sliding direction of the slider 53.

[0038] In this embodiment, a support leg 55 is installed at the bottom of the support plate 51. The support leg 55 is located outside the bed frame of the bed body 1, and the support leg 55 assists in supporting the support plate 51.

[0039] In this embodiment, the height of the outrigger 55 is adjustable, depending on the height of the bed body 1, so as to facilitate the support of the lifting plate 51. The outrigger 55 can be a manual telescopic rod or an electric push rod, both of which are existing conventional technologies. As long as it is ensured that within the height adjustment range of the bed body 1, the outrigger 55 can be adjusted to fit with the ground and play a supporting role.

[0040] Furthermore, casters can be installed at the bottom of the outrigger 55, making it easier for the lifting plate 51 to extend, retract, or slide.

[0041] In this embodiment, a handle 56 is installed on the outer wall of the lifting plate 51, which facilitates the pulling out of the lifting plate 51 so that it can slide or extend.

[0042] The following is a method for using a nursing bed for replacing a PICC in this embodiment:

[0043] First, the patient chooses a suitable orientation based on their own condition and lies down on the bed body 1, with the PICC tube positioned on the side of the lifting component 5. Then, the lifting mechanism 4 at the end where the patient's head is located is adjusted. Through the action of the electric push rod 42, the bed board 2 corresponding to the side of the patient's head is rotated and lifted, adjusting the patient's lying position and improving comfort.

[0044] Then, by adjusting the outrigger 55, the bottom of the outrigger 55 is brought into contact with the ground for auxiliary support. The lifting plate 51 is pulled outward by the handle 56, so that the lifting plate 51 moves along the extension direction of the guide rod 54 until the limiting block 52 and the slider 53 are in contact. The lifting plate 51 is then pulled by the handle 56 to slide in the moving groove 12. At this time, the slider 53 moves on the slide rail 13 until the lifting plate 51 moves to the limb where the PICC tube is located. Finally, the patient's limb is placed on the lifting plate 51. The lifting plate 51 supports the limb, making it easier to complete the relevant operations for replacing the PICC. After the replacement is completed, the device is restored to its original state and ready for the next use.

[0045] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
