Description

Technical Field

[0001] This utility model relates to the field of postoperative rehabilitation medical equipment technology, and in particular to a rehabilitation walker that integrates an infusion pump and a rapid sitting and resting function. Background Technology

[0002] With advancements in medical rehabilitation concepts, early ambulation after surgery has become a crucial aspect of accelerating recovery. Currently, adult walkers, as postoperative walking aids, generally employ an open-frame structure. While providing stable support, their functional design remains limited to single-function walking training. In practical clinical applications, patients often require simultaneous intravenous infusion therapy. Traditional solutions typically involve operating the walker separately from the independently moving IV stand, leading to cumbersome equipment management, limited mobility, and the risk of IV tubing dislodgement due to asynchronous equipment movement, posing a medical safety hazard.

[0003] Most existing adult walkers have their seats located in the middle of the vehicle. When patients are physically exhausted, they need to stop walking, adjust their body orientation, and slowly step out of the walker frame. They can only sit down and rest after a family member has installed the seat. This procedure poses a risk of secondary injury to patients who are weak or have slow movement after surgery, especially if no one is there to assist them in time. They may fall due to instability during the turning process.

[0004] In summary, current technologies have not effectively solved the problem of equipment coordination between medical monitoring and rehabilitation training. Patients are forced to perform repetitive operations during scenarios such as walking, intravenous infusion, and rest, which reduces rehabilitation efficiency and increases the difficulty of care. Especially in emergency situations such as sudden physical exhaustion, the fragmented design of equipment functional modules makes it difficult to provide timely and safe emergency support for patients. This contradiction is particularly prominent in the field of postoperative rehabilitation. Utility Model Content

[0005] The purpose of this invention is to provide a rehabilitation walker that integrates an infusion pump and a quick sitting and resting function, so that patients can receive intravenous infusions simultaneously during walking rehabilitation training and can quickly sit down and rest.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rehabilitation walking vehicle integrating an infusion pump and a quick sitting and resting function, comprising a main frame with walking wheels and a handrail, a portable infusion pump assembly detachably connected to the main frame, a sitting and resting device provided on the rear side of the main frame, the sitting and resting device comprising a symmetrically distributed and foldable seat plate, the seat plate having a vertically folded state and a horizontally unfolded state, and an infusion rod assembly fixed to the top of the main frame.

[0007] Preferably, a shelf is provided on the front side of the main frame, the infusion pump assembly is placed in the shelf, and the inner wall of the shelf is provided with an elastic buffer pad for supporting the infusion pump assembly to maintain its stability.

[0008] More preferably, the seating device includes two support rods respectively connected to the rear sides of the main frame. The support rods are vertically arranged and fixedly connected to the main frame by a connecting rod. A fixed shaft is vertically inserted through the bottom end of the support rod. The seat plate is hinged to the fixed shaft on the corresponding side. An avoidance groove is opened in the middle of one side of the seat plate. When the seat plate is horizontally unfolded, the inner wall of the avoidance groove abuts against the corresponding support rod to limit the position and keep the seat plate horizontal. The seat plate can be flipped upward to rest against the support rod for vertical storage.

[0009] More preferably, the surface of the seat plate is further provided with a cushion made of soft material.

[0010] More preferably, the infusion pole assembly includes a telescopic upright and a crossbeam connected to the top of the upright, and the crossbeam is provided with at least two infusion hooks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By detachably connecting the portable infusion pump assembly to the main frame, and combining it with the infusion pole assembly fixed at the top, the infusion therapy system and walking training equipment are physically integrated. This innovative structure integrates the traditionally separate infusion stand, infusion pump, and walker into a unified functional unit. During walking rehabilitation training, the infusion tubing maintains a synchronized movement trajectory with the body, effectively eliminating the risks of tubing traction and twisting caused by asynchronous equipment movement in traditional methods. It also reduces the workload for medical staff who frequently need to adjust the equipment's position.

[0013] 2. The symmetrical folding seat utilizes a mechanism that allows for both vertical folding and horizontal unfolding. In the event of sudden weakness in the patient, the seat can be instantly unfolded by a caregiver with a single step. Compared to traditional centrally fixed seat cushions that require the patient to turn around and exit, the rear-mounted seat, after unfolding horizontally, directly forms a support plane behind the patient's direction of travel. This allows the patient to seamlessly switch between walking and sitting without changing their posture. This design is particularly suitable for postoperative patients with insufficient muscle strength and poor balance. Attached Figure Description

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] It should be noted in advance that, in this utility model, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, in this utility model, unless otherwise explicitly specified and limited, "on" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.

[0023] like Figure 1 and Figure 2 As shown, the rehabilitation walker integrating an infusion pump and a quick sitting and resting function includes a main frame 3 with walking wheels 1 and a handrail 2. A portable infusion pump assembly 4 is detachably connected to the main frame 3. A sitting and resting device is provided on the rear side of the main frame 3. The sitting and resting device includes a symmetrically distributed and foldable seat plate 5. The seat plate 5 has a vertically folded state and a horizontally unfolded state. An infusion rod assembly is fixed to the top of the main frame 3. The walking wheels 1, handrail 2 and main frame 3 can adopt the existing structure of adult walkers, and the walking wheels 1 are also equipped with a conventional braking structure.

[0024] In the above structure, a shelf 6 is provided on the front side of the main frame 3, and the infusion pump assembly 4 is placed in the shelf 6. The inner wall of the shelf 6 is provided with an elastic buffer pad (not shown in the figure) to hold the infusion pump assembly 4 against it and keep it stable. It should be noted that the infusion pump assembly 4 in this embodiment can be a readily available portable infusion pump, such as the Shenke SK-600I micro infusion pump, which has a rechargeable battery and does not require a power supply, making it suitable for the walker in this embodiment.

[0025] By setting an elastic buffer pad on the inner wall of the front shelf 6, the infusion pump assembly 4 is given three-dimensional dynamic constraint during the movement of the walker. This not only meets the quick assembly and disassembly requirements of commercially available standard infusion pumps, but also absorbs the vibration energy of walking through elastic deformation. At the same time, the front-positioned layout of the shelf 6 allows medical staff to easily adjust the infusion parameters while walking. Combined with the continuous power supply characteristics of the rechargeable battery, it ensures the smooth and continuous progress of the treatment process and rehabilitation training.

[0026] The seating device in this embodiment includes two support rods 7 connected to the rear sides of the main frame 3. The support rods 7 are vertically arranged and fixedly connected to the main frame 3 via connecting rods. A fixed shaft 8 is vertically inserted through the bottom end of the support rod 7. The seat plate 5 is hinged to the fixed shaft 8 on the corresponding side. An avoidance groove 9 is opened in the middle of one side of the seat plate 5. When the seat plate 5 is horizontally unfolded, the inner wall of the avoidance groove 9 abuts against the corresponding support rod 7 to limit the seat plate 5 and keep it horizontal. The seat plate 5 can be flipped upwards to rest against the support rod 7 for vertical storage. The structural principle can be referred to the footrest folding structure in existing wheelchair structures. The seat plate 5 can be made of rigid plastic, and the surface of the seat plate 5 is also provided with a cushion made of soft material (not shown in the attached figure). The seat plate 5 with this structure allows a single caregiver to quickly switch states and meet the immediate response needs of emergency seating. The limiting cooperation between the avoidance groove 9 of the seat plate 5 and the support rod 7 can form sufficient support when the seat plate 5 is unfolded, and it will not easily deform when bearing the weight of an average adult.

[0027] Furthermore, it should be noted that the walker in this embodiment has four wheels 1, two on the front and two on the back, and the two on the back have a braking mechanism (refer to the mechanism of a conventional walker). When the seat 5 is opened to a horizontal position, the two wheels 1 on the back are located on the outside and slightly behind the seat 5. This ensures that the patient's center of gravity will not shift to the rear of the walker after sitting down (there are also walking wheel structures on both sides below the body when sitting down), thus preventing the walker from becoming unstable or tipping over due to a shift in the center of gravity.

[0028] Additionally, the infusion pole assembly includes a telescopic upright 10 and a crossbeam 11 connected to the top of the upright, with at least two infusion hooks on the crossbeam 11. The telescopic upright 10 allows for easy adjustment of the height of the infusion hooks to accommodate the venous pressure differential needs of patients of different heights.

[0029] The general procedure for using the rehabilitation walker with integrated infusion pump and rapid sitting function provided in the above embodiments is as follows:

[0030] First, adjust the upright 10 of the infusion pole assembly to a suitable height, suspend the infusion bag from the infusion hook on the crossbeam 11 to avoid interference with the handrail 2, and ensure that the infusion tubing has sufficient length to accommodate the increased distance between the patient's hand and the infusion bag after sitting down. Then, the patient holds onto the handrail 2 and enters the walker frame. The nursing staff starts the infusion pump 4 and sets the parameters. The operation of using the infusion pump 4 to administer infusion to the patient can be performed according to standard nursing procedures. During the journey, the vibration energy of the infusion pump 4 can be absorbed by the elastic cushioning pad of the shelf 6, and at the same time, the infusion hook maintains a constant liquid level difference with the height of the upright 10 to ensure a stable flow rate.

[0031] As those skilled in the art know, standard nursing care requires postoperative patients to be accompanied by family members or caregivers when using a walker for rehabilitation training. Therefore, when the patient is physically exhausted, the caregiver or accompanying family member can move the seat plate 5, causing the two seat plates 5 to fold down around the fixed axis 8 to a horizontally unfolded state. At this time, the inner wall of the clearance groove 9 abuts against the support rod 7 to form a self-locking mechanism. The patient can then move back half a step to sit directly on the soft cushion, and the infusion pump 4 can continue to operate without being affected during the rest period. After resting, the patient stands up, and the caregiver or accompanying family member pushes the seat plate 5 upward to the vertical storage position, where the seat plate 5 can reliably engage with the support rod 7 on the corresponding side. When finished using the device, first turn off the infusion pump 4, retract the upright rod 10 to its lowest position, remove the infusion bag, and then remove the infusion pump assembly 4 from the shelf 6 for charging, making it convenient for the next use.

[0032] This invention integrates a portable infusion pump assembly, a quickly convertible sitting device, and an infusion pole assembly into the main frame of a baby walker. Through optimized spatial layout design, each functional module effectively achieves coordinated operation of infusion therapy and walking training. Furthermore, in the event of sudden weakness in the patient, the seat can be quickly deployed for rest, greatly facilitating postoperative recovery training.

[0033] To facilitate understanding by those skilled in the art of the improvements of this utility model compared to the prior art, some of the accompanying drawings and descriptions of this utility model have been simplified. The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
