Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically to a medical mini trolley. Background Technology

[0002] In the medical field, microinfusion pumps, or micropumps for short, are widely used in scenarios requiring continuous and stable drug delivery, especially in departments such as proctology. For postoperative analgesia, hemostasis, and other treatment needs, patients often require 24-hour uninterrupted drug infusion via micropumps to ensure treatment effectiveness.

[0003] Currently, in clinical practice, micropumps are typically placed on a fixed table next to the patient's bed, on a regular nursing cart, or directly on the bedside. Their location is relatively fixed, and they mainly rely on the infusion tubing connected to the patient's intravenous access to deliver medication. When the patient needs to leave the bed, because micropumps lack convenient portable carriers, medical staff often need to manually stop the micropump and seal the infusion tubing. The micropump is then restarted and the tubing flushed after the patient returns to the bed to resume the medication delivery process.

[0004] Since the micropump medication needs to be paused every time the patient gets out of bed, the drug infusion will be interrupted. Frequent interruptions can disrupt the stable concentration of the drug in the body and affect the treatment effect. This is especially true for patients who need continuous analgesia and to maintain coagulation function after surgery in the proctology department, where the continuity of drug infusion is directly related to the recovery process. At the same time, each interruption and resumption of medication requires the intervention of nurses, which not only increases the workload of medical staff and reduces nursing efficiency, but may also increase the risk of tubing contamination due to frequent operations.

[0005] Therefore, we propose a medical mini trolley. Utility Model Content

[0006] This invention provides a medical mini trolley with a swivel wheel structure. A micropump is placed in a groove on the surface of the trolley, and the infusion rod is inserted into a hollow support rod. A foldable support component is also provided for patient support. This allows patients to use the micropump without interrupting medication when getting out of bed to use the toilet or moving around, maintaining continuous drug infusion. Furthermore, patients can move independently without frequently calling for nurses' assistance. This solves the problems mentioned in the background art, namely, the frequent interruptions of medication due to patient movement when using the micropump, which affects treatment effectiveness and increases the workload of nurses.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A medical mini trolley includes a handcart on which an infusion rod and a micropump are placed. The handcart includes two panels, which are fixedly connected at the four corners by a support rod. The bottom of the support rod is provided with casters. The panels are used to support the micropump. Two support components are fixedly connected to one side of the outer wall of the board. The support components can be folded onto the outer wall of the board and are used to support the patient's hand strength and assist the patient in walking with the help of the trolley.

[0008] Preferably, the top of the plate is recessed downward to form a shallow groove, and the groove has multiple round holes. One end of the micropump is provided with a bracket, which has multiple round holes. A screw is threaded between the plate and the round holes of the bracket, and the screw is used to fix the micropump on the plate.

[0009] Preferably, the support rod has a hollow structure inside, and an infusion rod is placed inside the support rod. A caster wheel is fixedly connected to the bottom of the support rod. The caster wheel is used to drive the trolley to move as a whole, and the support rod is used to assist the infusion rod in being inserted into the interior for support.

[0010] Preferably, the support assembly includes a support plate, which is fixedly connected to the outer wall of the plate by a right-angle hinge. The right-angle hinge causes the support plate to fold on the outer wall of the plate, and the support plate is used to support the patient's arm.

[0011] Preferably, the support board consists of two parts: a thin plate and a thick plate. The thick plate is used to assist the patient's arm in support, while the thin plate is used to place the patient's hand and facilitate hand gripping and force application.

[0012] Preferably, the outer walls on both sides of the thin plate portion of the support board are provided with multiple recesses, which are used to match the gripping position of the patient's fingers.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In a medical mini trolley, the trolley serves as the supporting base, with a shallow groove on the board surface to hold a micropump. At the same time, a hollow support rod provides support for the infusion rod, making the micropump and infusion system a whole that can move synchronously with the patient. The patient can push the trolley independently through the support components, so that when the patient gets out of bed, there is no need for nurses to repeatedly intervene to perform operations such as sealing and restarting the tube. This reduces the workload of nurses while ensuring continuous drug infusion and avoiding frequent interruptions that affect the treatment effect.

[0014] 2. In a medical mini trolley, the armrests are folded using right-angle hinges. When not in use, they can be stored on the outer wall of the armrest to save space, and unfolded for patient support when in use. Because the thicker part of the armrest is larger than the thinner part, the thicker part can support the patient's entire arm, providing stable support and distributing the force on the hand. For hands receiving intravenous infusions, this reduces pressure and traction at the puncture site, preventing pain, swelling, or extravasation of the puncture site due to concentrated force, thus maintaining the stability of the infusion. The thinner part, with its recessed sides, conforms to the hand's gripping needs, making the grip more stable and effortless, preventing slippage, and improving the stability of the patient's independent operation of the trolley.

[0015] 3. The casters in this application are equipped with brake pads, which adjust the flexibility of the casters. When the patient has difficulty moving and the trolley needs to be moved along with the patient, the resistance of the casters can be adjusted to reduce the flexibility. Nurses or family members can control the trolley to its most flexible position when moving it. With the brake pads, the trolley is also more stable when placed on the hospital bed.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example Please see Figures 1-4The illustration shows a medical mini trolley, including a trolley 1, on which an infusion rod 2 and a micro pump 3 are placed. The trolley 1 includes two panels 11, which are fixedly connected at the four corners by a support rod 12. The bottom of the support rod 12 is equipped with casters 13. The panels 11 are used to support the micro pump 3. Two support components 14 are fixedly connected to one side of the outer wall of the panel 11. The support components 14 can be folded on the outer wall of the panel 11. The support components 14 are used to support the patient's hand strength and assist the patient to walk with the help of the trolley 1.

[0019] Among them, see Figure 1 and Figure 2 As shown, the top of the plate 11 is recessed downward to form a shallow groove. Multiple round holes are provided inside the groove of the plate 11. A bracket 31 is provided at one end of the micropump 3. Multiple round holes are provided on the bracket 31. A screw 32 is threaded between the plate 11 and the round holes of the bracket 31. The screw 32 is used to fix the micropump 3 on the plate 11.

[0020] The support rod 12 has a hollow structure inside, and the infusion rod 2 is placed inside the support rod 12. The bottom of the support rod 12 is fixedly connected to the universal wheel 13, which is used to drive the trolley 1 to move as a whole. The support rod 12 is used to assist the infusion rod 2 to be inserted into the interior for support.

[0021] When the micropump 3 is placed in the groove, the shallow groove at the top of the plate 11 provides initial positioning for the micropump 3. The multiple round holes inside the groove correspond precisely to the round holes on the bracket 31 at one end of the micropump 3. The micropump 3 is firmly fixed on the plate 11 by passing through the round holes of both and connecting them with threads, thus preventing the micropump 3 from shifting or slipping during the movement of the trolley 1, and further ensuring the stable working state of the micropump 3. The hollow structure inside the support rod 12 provides an installation channel for the infusion rod 2. After the infusion rod 2 is inserted into the support rod 12, the support rod 12 can provide radial support for it, ensuring that the infusion rod 2 remains upright during use and preventing the infusion rod 2 from tipping over and affecting the infusion. It should be noted that in this application, a mobile charging module is also installed on one of the panels 11. This charging module can serve as a temporary power source for the micro pump and can also power other charging devices.

[0022] In the proposed implementation scheme, the commonly used micropump dimensions are approximately 34cm in length, 15cm in width, and 20cm in height. To facilitate placement of the micropump and its ease of use in wards, the plate surface 11 can be designed to be slightly larger than the micropump. Preferably, the plate surface 11 is designed to be 40cm in length and 25cm in width, allowing space for a mobile charging module as well.

[0023] This application places the micropump on a handcart 1, allowing the patient to easily move around by pushing the handcart 1 when needed. It eliminates concerns about securing or removing the micropump. For greater patient convenience, the handcart 1 is positioned at a height of 70cm-90cm for wider adaptability.

[0024] The casters 13 at the bottom of the support rod 12 rotate flexibly with the direction of the patient's movement, driving the entire trolley 1 to move synchronously with the patient, so that the micropump 3 and the infusion system always maintain a relatively stable positional relationship when the patient moves, thereby achieving the effect of continuous drug administration by the micropump 3 and no interference with the infusion process when the patient gets out of bed.

[0025] For details, please refer to Figure 3 and Figure 4 As shown, the support assembly 14 includes a support plate 140, which is fixedly connected to the outer wall of the plate surface 11 by a right-angle hinge 141. The right-angle hinge 141 drives the support plate 140 to fold on the outer wall of the plate surface 11. The support plate 140 is used to support the patient's arm.

[0026] When the patient needs to use the support board 140, the support board 140 can be unfolded from the outer wall of the board surface 11 to a state perpendicular to the board surface 11 by rotating the right-angle hinge 141. At this time, the support board 140 can provide a support surface for the patient's arm. When the support board 140 is not needed, the support board 140 can be folded and fitted to the outer wall of the board surface 11 by rotating the right-angle hinge 141 in the opposite direction, reducing space occupation.

[0027] As is known to those skilled in the art, the right-angle hinge 141 works by fixing the two ends of the hinge to the support plate 140 and the plate surface 11 respectively, and achieving relative rotation between the two with the hinge axis as the rotation center. During rotation, the hinge has a matching locking structure inside. When the support plate 140 rotates around the hinge axis to the outside of the plate surface 11 to a 90° right angle with the plate surface 11, the locking component inside the hinge will engage to form a rigid lock. At this time, the support plate 140 cannot continue to rotate, thereby stably supporting the pressure applied by the patient's arm. When it is necessary to fold the support plate 140, a reverse force needs to be applied to the support plate 140 to overcome the locking force of the locking structure, so that the locking component disengages from the engagement state. The support plate 140 can then rotate in the opposite direction around the hinge axis and fit against the outer wall of the plate surface 11 to complete the folding and storage.

[0028] See Figure 3 As shown, the support board 140 consists of two parts: a thin plate and a thick plate. The thick plate of the support board 140 is used to assist the patient's arm support, while the thin plate of the support board 140 is used to place the patient's hand and facilitate hand gripping and force application. The outer walls on both sides of the thin plate of the support board 140 have multiple recesses to match the gripping position of the patient's fingers.

[0029] Because the thicker part of the support plate 140 is larger than the thinner part, it can support the patient's entire arm, providing a larger area of ​​support, distributing the force on the hand, and reducing pressure and traction on the puncture site during infusion. This avoids discomfort at the puncture site or interference with the infusion due to concentrated force. The thinner part is used to assist in hand gripping. Multiple notches on its outer walls on both sides match the natural curvature of the patient's fingers, allowing the fingers to be firmly embedded in the notches, enhancing the stability and ease of gripping, and preventing slippage. The support plate 140 also assists the patient in maintaining balance when pushing the trolley 1, ensuring the stability of the micro-pump 3 and the infusion system during movement. This allows the patient to walk independently by pushing the trolley 1, avoiding the need for nurses to repeatedly intervene to perform procedures such as sealing and restarting the catheter when the patient gets out of bed, thus reducing the workload of nurses.

[0030] In addition, the casters 13 of this application are equipped with brake pads, which can adjust the flexibility of the casters 13. When the patient has difficulty moving and the trolley needs to be moved together, the resistance of the casters 13 can be adjusted appropriately to reduce the flexibility. When the nurse or family member moves the trolley 1, the trolley can be controlled to be in the most flexible state. With the brake pads, the trolley 1 is also more stable when placed on the hospital bed.
