Description

Technical Field

[0001] The present invention relates to the technical field of drug preparation, and in particular to a drug preparation hand exoskeleton. Background Art

[0002] In the medical field, drug preparation is a vital task that is directly related to the treatment effect and safety of patients. In the traditional drug preparation process, medical staff need to perform delicate manual operations for a long time, such as extracting and injecting drug solutions, etc. These operations not only require high accuracy and stability, but are also often accompanied by a large workload and fatigue. Especially when handling certain special drugs, such as chemotherapy drugs that require precise dosage control, any slight hand shaking or uneven strength may cause errors in the drug dosage, thereby affecting the treatment effect.

[0003] In order to improve the efficiency and accuracy of drug preparation and reduce the workload of medical staff, some auxiliary tools have appeared on the market, such as traditional medical gloves or simple mechanical assist devices. However, these tools often have many shortcomings. For example, although traditional medical gloves can provide basic protection, they are limited in improving finger flexibility and clamping force, and cannot meet the needs of delicate operations; and some simple mechanical assist devices may fail to achieve the expected effect in actual use due to unreasonable design or insufficient intelligence, and may even increase the complexity of operation. Summary of the invention

[0004] The purpose of the present invention is to provide a drug preparation hand exoskeleton to solve the problem mentioned in the above background technology that although traditional medical gloves can provide basic protection, they have limited effect in improving finger flexibility and clamping force and cannot meet the needs of delicate operations.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a drug dispensing hand exoskeleton, comprising: a glove body made of a breathable material and a glove tightening opening with elastic, the glove tightening opening being arranged at the tail end of the glove body, a tail plate being connected to the finger joints of the glove body, a middle plate being installed at the head of the tail plate through a movable shaft, and the tail plate being connected to the finger plate through a power-assisting structure;

[0006] A proximal joint groove is arranged between the knuckle plate and the middle joint plate, a middle joint groove is arranged between the middle joint plate and the tail joint plate, and a retractable rubber is connected to the palm of the glove body.

[0007] Preferably, the power-assisting structure includes a movable rod, a hydraulic cylinder, a movable plate and a head plate, one end of the movable rod is rotatably connected to the tail end of the hydraulic cylinder, the head end of the hydraulic cylinder is rotatably connected to the movable plate, and the other end of the movable plate is rotatably connected to the head plate.

[0008] Preferably, one end of the movable rod and the head plate are respectively connected to the tail joint plate and the finger joint plate through a rotating shaft.

[0009] Preferably, an extended protrusion is provided at the rear end of the knuckle plate, and the protrusion is rotationally connected to the head plate via a rotation axis.

[0010] Preferably, the knuckle plate includes a vent hole and a fingerprint. The knuckle plate is provided with a vent hole and the fingerprint is provided at the knuckle plate.

[0011] Preferably, the elastic rod comprises a movable rod, a sleeve rod and a restoring spring, one end of the movable rod is movably and telescopically installed inside the sleeve rod, a restoring spring is connected between the movable rod and the sleeve rod, and an elastic telescopic structure is formed.

[0012] Preferably, two ends of the elastic rod are respectively connected to the tail section plate and the movable rod through a movable shaft.

[0013] Preferably, the retractable rubber includes a gasket, an extrusion spring and a bottom gasket, the gasket extends into the interior of the bottom gasket, and the bottom of the gasket is connected to the extrusion spring and the inner wall of the bottom gasket.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The drug dispensing hand exoskeleton significantly improves finger flexibility: through the designed tail plate, middle plate and finger plate structure, combined with the movable axis and power-assisting structure, the present invention effectively enhances the range of motion and flexibility of the fingers after wearing gloves. In particular, the hydraulic cylinder in the power-assisting structure performs dynamic assistance according to the strength of the natural bending of the fingers, so that the fingers are almost free of additional burden when clamping and releasing the syringe, greatly reducing the operating fatigue of medical staff.

[0016] 2. The drug dispensing hand exoskeleton can accurately control the configuration of the drug solution: the five hydraulic cylinders can be controlled independently and can respond intelligently according to the actual strength of the medical staff during operation. This not only ensures the stability of the syringe when extracting and injecting the drug solution, but also realizes the precise control of the drug solution dosage, avoids errors caused by hand shaking or uneven strength, and improves the accuracy and safety of drug solution configuration.

[0017] 3. The drug is equipped with a hand exoskeleton to enhance the grip and friction: the ventilation holes on the knuckle plate ensure the breathability of the fingers and avoid discomfort caused by long-term wear; at the same time, the fingerprint-simulating design on the knuckle plate increases the contact friction with the surface of the syringe, so that the syringe can be firmly clamped even under the cover of gloves, reducing the risk of slipping and further ensuring the smooth operation.

[0018] 4. The drug dispensing hand exoskeleton has an innovative retractable rubber structure to assist in drug liquid management: the retractable rubber has a built-in extrusion spring that can assist the piston when the finger releases the syringe sleeve rod, so that both extraction and injection of drug liquid can be achieved with smooth and powerful movements, reducing the difficulty and intensity of manual operation. In addition, its rebound structure can effectively resist the piston head to prevent accidental leakage of drug liquid, keeping the working environment clean and safe.

[0019] 5. The exoskeleton gloves of the present invention not only significantly improve the efficiency of liquid medicine preparation and reduce the workload of medical staff through a series of innovative designs, but also greatly improve the comfort and accuracy of operation by enhancing finger flexibility, optimizing clamping force, introducing intelligent power-assisting systems and other measures, providing medical staff with a more humane and intelligent work auxiliary tool, which is of great significance for improving the quality of medical services and the satisfaction of medical staff.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6 The present invention provides a technical solution: a drug dispensing hand exoskeleton, comprising: a glove body 1 made of a breathable material and a glove tightening opening 2 with elasticity, the glove body 1 having a glove tightening opening 2 at the tail end, a tail plate 3 connected to the finger joints of the glove body 1, a middle plate 5 installed at the head of the tail plate 3 through a movable shaft 4, and the tail plate 3 connected to the finger plate 6 through a power-assisting structure, and the tail plate 3, the middle plate 5 and the finger plate 6 are provided in this solution to further increase the flexibility of the fingers;

[0029] A proximal joint groove 13 is provided between the knuckle plate 6 and the middle joint plate 5, a middle joint groove 12 is provided between the middle joint plate 5 and the tail joint plate 3, and a retractable rubber 14 is connected to the palm of the glove body 1. The proximal joint groove 13 can facilitate the bending of the knuckle plate 6, and the middle joint groove 12 can facilitate the bending of the middle joint plate 5 and the tail joint plate 3, thereby reducing the impact of the exoskeleton glove on holding the syringe.

[0030] The power-assisting structure includes a movable rod 7, a hydraulic cylinder 8, a movable plate 9 and a head plate 10. One end of the movable rod 7 is rotatably connected to the tail end of the hydraulic cylinder 8, the head of the hydraulic cylinder 8 is rotatably connected to the movable plate 9, and the other end of the movable plate 9 is rotatably connected to the head plate 10. The power-assisting structure can assist the nurse's fingers to clamp the syringe. The hydraulic cylinder 8 is connected to the hydraulic pump, and the five hydraulic cylinders 8 can be controlled and connected separately. When the power-assisting structure recognizes the strength of the finger, it calculates the strength of the finger, and the hydraulic cylinder 8 assists according to the strength of the active bending of the finger, so that most of the strength of the finger bending is driven by the hydraulic cylinder 8, so that the strength for clamping and releasing the syringe is provided by the hydraulic cylinder 8.

[0031] One end of the movable rod 7 and the head plate 10 are respectively connected to the tail joint plate 3 and the finger joint plate 6 through a rotating shaft, so that the two ends of the power-assisting structure can rotate on the tail joint plate 3 and the finger joint plate 6. When the nurse is configuring the infusion, the power-assisting structure can provide auxiliary power when configuring the infusion force, making it easier for the nurse to configure the infusion.

[0032] The rear end of the knuckle plate 6 is provided with an extended protrusion, which is rotatably connected to the head plate 10 via a rotating shaft. By providing the protrusion on the knuckle plate 6, the pushing force of the head plate 10 to pull the knuckle plate 6 can be increased, thereby facilitating the bending of the knuckle plate 6 and further assisting the bending of the fingers.

[0033] The knuckle plate 6 includes a ventilation hole 61 and a fingerprint 62. The knuckle plate 6 is provided with a ventilation hole 61, and a fingerprint 62 is provided at the fingerprint position of the knuckle plate 6. The ventilation hole 61 can increase the ventilation of the finger, and the fingerprint 62 can increase the friction with the surface of the syringe, thereby reducing the clamping force on the syringe.

[0034] The elastic rod 11 includes a moving rod 111, a sleeve rod 112 and a restoring spring 113. One end of the moving rod 111 is movably and telescopically installed inside the sleeve rod 112. A restoring spring 113 is connected between the moving rod 111 and the sleeve rod 112 to form an elastic telescopic structure. When the power-assisting structure returns to its original state, the elastic rod 11 can ensure that the position of the hydraulic cylinder 8 is inconvenient.

[0035] The two ends of the elastic rod 11 are respectively connected to the tail section plate 3 and the movable rod 7 through a movable shaft, and the two ends of the elastic rod 11 can be rotatably connected to the tail section plate 3 and the movable rod 7 respectively.

[0036] The retractable rubber 14 includes a gasket 141, an extrusion spring 142 and a bottom pad 143. The gasket 141 extends into the interior of the bottom pad 143. The bottom of the gasket 141 is connected to the extrusion spring 142 and is connected to the inner wall of the bottom pad 143. The rubber material of the gasket 141 and the bottom pad 143 can form a rebound structure. When the gasket 141 and the bottom pad 143 are compressed, they will be deformed. At the same time, the extrusion spring 142 can restore the extrusion force under the action of elasticity, so that the drawn syringe piston can be supported and the piston can be helped when the syringe sleeve rod is released.

[0037] In summary: Figure 1-6As shown, when using the hand exoskeleton for preparing medicine, first prepare the configured medicine and syringe, then put the exoskeleton glove on the hand, when the medical staff wearing the exoskeleton glove prepares the liquid medicine, insert the head of the syringe into the medicine bottle, then clamp the syringe with the middle finger and index finger, and bend the middle finger and index finger. When the fingers are bent, the hydraulic cylinder 8 is driven by the driving force, and the force is fed back to the hydraulic pump, and the hydraulic pump feeds back the force to the corresponding hydraulic cylinder 8, the length of the hydraulic cylinder 8 increases, and the hydraulic cylinder 8 drives the movable plate 9 and the head plate 10 to rotate, and at the same time the knuckle plates 6 of the middle finger and index finger are bent, thereby achieving The syringe is clamped with assistance, and then the thumb is also bent with assistance by the hydraulic cylinder 8, and the back of the thumb's knuckle plate 6 is pressed against the back of the syringe's piston head, and then the thumb is opened with assistance by the hydraulic cylinder 8. As the thumb is opened, the piston gradually grows, so that the syringe draws out the liquid medicine, and the liquid medicine in the syringe is injected into other liquid medicine bottles for preparation, and then the retractable rubber 14 of the exoskeleton glove is pressed against the head of the piston, and at the same time, the middle finger and index finger clamp the syringe in a vertical state, and then the middle finger and index finger are gradually bent, and the hydraulic cylinder 8 assists the bending force of the middle finger and index finger when bending. The piston can inject the liquid medicine in the syringe into the inside of the configured liquid medicine, so that the assistance configuration of the liquid medicine can be easily completed, so that medical staff can more easily perform liquid medicine configuration injection.
