Description

Technical Field

[0001] This invention relates to a medical aid, and more particularly to a gripping device for holding medicine bottles. Prior Technology

[0002] Medical sharps injuries are a common occupational hazard for medical personnel, potentially exposing them to the risk of infection with various infectious diseases. This can cause immense psychological stress for those who frequently use medical sharps such as syringes.

[0003] Taiwanese Patent No. M430287 discloses a clamping device. This clamping device includes a hollow tubular structure with opposite ends, and a shield connecting one end of the opposite ends of the tubular structure. One end of the opposite ends of the tubular structure has a first opening, and the other end has a second opening. The shield is disposed at the first opening of the tubular structure. In use, the clamping device is fitted around the periphery of a sample tube, with the non-open end of the sample tube exposed outside the first opening and the open end of the sample tube exposed outside the second opening. An injection device injects the contents of the sample tube through a needle via the open end of the sample tube exposed outside the second opening.

[0004] However, this gripping device can only be used on specimen tubes of a fixed size. Frontline medical personnel frequently deal with medicine bottles of various sizes, clearly indicating that this gripping device is insufficient to meet their actual needs. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a gripping device that can improve upon at least one of the disadvantages of the prior art.

[0006] Therefore, the clamping device of the present invention is suitable for clamping a medicine bottle, and includes a handle mechanism, an operating mechanism, a transmission mechanism, and a clamping mechanism.

[0007] The operating mechanism includes an adjustment and positioning unit installed on the grip mechanism and operable to be positioned relative to the grip mechanism by moving back and forth, and a linkage extending forward from the adjustment and positioning unit, which can be moved by the adjustment and positioning unit.

[0008] The transmission mechanism is mounted and positioned on the grip mechanism and includes two transmission rods that extend forward and backward and are pivotable at their front ends relative to the grip mechanism from left to right. These transmission rods are located on the left and right sides of the linkage, respectively.

[0009] The clamping mechanism includes two clamps that are pivotally connected to the front ends of the transmission rods and pivotally connected to the front ends of the linkage, respectively, and are spaced apart from each other and pivotable to the left and right. The clamps can be pulled backward by the linkage and pivot relative to the transmission rods, changing from an open state to a clamping state in which the medicine bottle is clamped by a ring that cooperates with the handle mechanism.

[0010] The advantages of this invention are as follows: By adjusting the operating mechanism relative to the handle mechanism, and through the structural design that drives the clamping mechanisms to change between the open and clamping states relative to the transmission mechanism, the medicine bottle can be gripped and retrieved by the cooperation of the clamping mechanisms and the handle mechanism, keeping the hand relatively away from the medicine bottle, thus helping to reduce the risk of needle pricks when extracting the medicine from the bottle. Furthermore, the structural design of the clamping mechanism changing between the open and clamping states can be used to grip medicine bottles of various sizes.

[0011] The clamping device of this invention can help medical personnel to pick up and discard the medicine bottle more conveniently, avoiding the risk of needle pricks faced by medical personnel when holding the medicine bottle, and also reducing the harm of medical personnel directly contacting corrosive or radioactive drugs, fully demonstrating the importance attached to the occupational safety and long-term health of medical personnel.

Implementation

[0013] Referring to Figures 1, 2, and 3, one embodiment of the gripping device of the present invention is suitable for gripping a medicine bottle 91. The gripping device includes a gripping handle mechanism 1, an operating mechanism 2 mounted on the gripping handle mechanism 1, a transmission mechanism 3 disposed on the gripping handle mechanism 1, a clamping mechanism 4 mounted on the operating mechanism 2 and connected to the transmission mechanism 3, and a holding handle 5 mounted on the gripping handle mechanism 1.

[0014] The grip mechanism 1 includes a grip 11 that extends forward and backward and is movable forward and backward for the operation mechanism 2, a storage shell 12 connected to the front end of the grip 11 and for the transmission mechanism 3 to be installed inside, and an outer ring 13 that is connected to the storage shell 12 at its left and right ends and cooperates with the storage shell 12 to define an active space 191.

[0015] Referring to Figures 2, 3, and 5, the handle 11 defines an upward-opening adjustment groove 14. The adjustment groove 14 has a front-to-back extending groove body 141 and a front-to-back extending opening 142 that connects the groove body 141 vertically to the outside. The opening 142 has several staggered partition segments 151 and several positioning segments 152, the lateral width of the partition segments 151 being smaller than the lateral width of the positioning segments 152.

[0016] Referring to Figures 1, 2 and 3, the storage shell 12 is fitted onto the front end of the handle 11, and is generally trapezoidal in shape with the width gradually increasing from left to right, defining a storage space 192 with an opening facing forward that connects to the active space 191.

[0017] The outer ring 13 is made of a ferromagnetic material that can be magnetically attracted, and a first connecting part 131 is provided on the outer periphery of the outer ring 13 away from the storage shell 12.

[0018] Referring to Figures 2, 3 and 4, the operating mechanism 2 includes an adjustment and positioning unit 21 installed on the handle 11 and operable to move back and forth relative to the handle 11, and a linkage 22 extending forward from the adjustment and positioning unit 21 into the storage space 192.

[0019] The adjustment and positioning unit 21 has a pressing member 211 exposed on the top side of the handle 11 and detachably embedded in one of the positioning sections 152, a sliding seat 212 disposed in the slot body 141 and connected to the rear end of the linkage 22, and an elastic member 213 connected between the pressing member 211 and the sliding seat 212. In this embodiment, the elastic member 213 is a wave-shaped spring sheet that extends back and forth and bends up and down. However, in other embodiments of the present invention, the elastic member 213 may also be, for example, but not limited to, a spring or other elastically compressible object.

[0020] The pressing member 211 has a pressing head 251 exposed on the top side of the handle 11, a latching portion 252 that can be disengaged downwards and locked in one of the positioning segments 152, and a neck 253 connecting the pressing head 251 and the latching portion 252 on their opposing vertical sides. The left-right width of the latching portion 252 is greater than the left-right width of the dividing segments 151, but smaller than the left-right width of the positioning segments 152. The left-right width of the neck 253 is smaller than the left-right width of the dividing segments 151.

[0021] Referring to Figures 5 and 6, the pressing member 211 can move vertically between a locked position and a disengaged position. When the pressing member 211 is in the locked position, the latching part 252 is pushed upward by the elastic member 213 and locked in one of the positioning segments 152 (as shown in Figure 5). When the pressing member 211 is to be moved to the disengaged position, the pressing head 251 is pressed downward, causing the latching part 252 to disengage downward from the originally locked positioning segment 152, and elastically pushing the elastic member 213 downward, causing the elastic member 213 to deform and accumulate an upward restoring elastic force, and causing the neck 253 to move downward to the positioning segment 152 (as shown in Figure 6).

[0022] When the adjustment and positioning unit 21 needs to be moved back and forth relative to the handle 11, the pressing member 211 can be pressed to move to the disengaged position. Then, the pressing head 251 is pushed back and forth relative to the handle 11, thereby moving the elastic member 213 and the sliding seat 212 in the groove 141 via the latching part 252 and the neck 253. When the latching part 252 is moved to align with another positioning segment 152, the pressing head 251 is released, and the reset force stored in the elastic member 213 will push the latching part 252 upward to reset it, so that the latching part 252 is engaged and positioned in the other positioning segment 152, thus completing the adjustment.

[0023] Referring to Figures 1 and 4, the transmission mechanism 3 is located in the storage space 192 and includes a fixed rod 31 extending laterally and fixed to the storage shell 12, and two transmission rods 32 that are pivotally connected to the two ends of the fixed rod 31 and extend forward in opposite directions. In other embodiments of the present invention, the fixed rod 31 is not necessary, and the rear ends of the transmission rods 32 can be pivotally mounted on the storage shell 12.

[0024] The clamping mechanism 4 includes two clamps 41 respectively pivotally connected to the front ends of the transmission rods 32 and coaxially pivotally connected to the front end of the linkage 22, and several anti-slip members 42 respectively disposed on the clamps 41. The clamps 41 are partially exposed in the movable space 191 and are coaxially pivotally connected to the front ends of the linkage 22 in a stacked manner.

[0025] Each of the clamps 41 has a pivot portion 411 that is pivotally connected horizontally between the corresponding transmission rod 32 and the linkage 22, and a gripping portion 412 that extends forward from one end of the pivot portion 411 that is pivotally connected to the transmission rod 32 and curves toward the other clamp 41.

[0026] The anti-slip components 42 are arranged longitudinally and spaced apart on the inner curved surface of the clamping portions 412. In this embodiment, the anti-slip components 42 are strip-shaped and made of silicone. Each anti-slip component 42 has the same length and is attached to the inner curved surface of the clamping portions 412 at equal intervals. In other embodiments, the shape, size, material, or spacing of the anti-slip components 42 can be changed according to the actual application.

[0027] The pivoting parts 411 can be driven by the linkage 22 to push and pull back and forth, thereby driving the gripping parts 412 to pivot left and right relative to the transmission rods 32. The grippers 41 can change between an open state where they are facing away from each other and a gripping state where they are tilted towards the storage shell 12 and can be used to clamp the medicine bottle 91. The operation transmission method by which the operating mechanism 2 can drive the grippers 41 to change between the open state and the gripping state will be explained later.

[0028] Referring to Figures 1 and 2, the handle 5 can be installed on one side of the outer ring 13, for example, on the left side of the outer ring 13.

[0029] The grip handle 5 includes an extension 51 that extends forward and backward and curves left and right, a magnetic part 52 disposed on the inner periphery of the curve of the extension 51, a T-shaped handle part 53 connected to the outer periphery of the curve of the extension 51, an inverted U-shaped clip part 54 connected to the front end of the extension 51, and a second connecting part 55 disposed in the front end section of the extension 51.

[0030] When the handle 5 is to be installed on the outer ring 13, the clip 54 is laterally clamped on the upper and lower sides of the front end of the grip 11, so that the extension 51 drives the magnetic part 52 to abut against the outer periphery of the outer ring 13, and the second connecting part 55 is connected to the first connecting part 131 to complete the assembly. At this time, the magnetic part 52 will be magnetically attracted to the outer ring 13.

[0031] In this embodiment, the first connecting part 131 and the second connecting part 55 are respectively the male and female fasteners in a set of male and female fasteners. However, in other embodiments of the present invention, the combination of the first connecting part 131 and the second connecting part 55 can be achieved by other types of fasteners, such as Velcro or snap fasteners, depending on the actual application. In addition, in this embodiment, the magnetic part 52 is a long strip-shaped soft magnet that completely fits the inner periphery of the extension part 51, and its number or shape can be changed depending on the actual application.

[0032] When the medicine bottle 91 is to be gripped by the gripping device of the present invention, the holding handle 5 can be first installed on the grip mechanism 1. Then, the medicine bottle 91 is placed in the movable space 191, between the opposing sides of the clamps 41. Next, the adjustment and positioning unit 21 is moved backward relative to the grip 11, thereby driving the linkage 22 to pull the pivoting portions 411 of the clamps 41 backward, thereby driving the clamps 41 to gradually pivot from the open state to the gripping state, until the gripping portions 412 cooperate with the storage shell 12 to clamp the medicine bottle 91. At this time, the gripping portions 412 will drive the anti-slip members 42 to abut against the medicine bottle 91, which helps to improve the gripping stability.

[0033] Once the medicine bottle 91 is securely clamped and the medication needs to be taken from the bottle 91 with a needle, the user can instead use their fingers to pass through the handle 5 to secure it in their hand. Since the operating mechanism 2 is not located on the handle 5, the user does not need to worry about accidentally touching the operating mechanism 2 and causing the medicine bottle 91 to fall off when holding the medicine bottle 91 through the handle 5, allowing for a safer and more secure grip on the medicine bottle 91 to take the medication.

[0034] When the medicine bottle 91 is to be released, the adjustment and positioning unit 21 can be pushed forward relative to the handle 11, thereby driving the linkage 22 to push the pivot parts 411 of the clamps 41 forward, thereby driving the gripping parts 412 to unfold and change to the open state, and releasing the medicine bottle 91.

[0035] In summary, by adjusting the operating mechanism 2 relative to the handle mechanism 1, and thereby driving the clamps 41 to change between the open and clamping states relative to the transmission mechanism 3, the clamping mechanism 41, in conjunction with the handle mechanism 1, can grip and retrieve the medicine bottle 91, keeping the hand relatively away from the bottle 91. This helps reduce the risk of needle pricks when extracting the medicine from the bottle 91. Furthermore, the design of the holding handle 5 further keeps the hand away from the bottle 91, preventing accidental release of the bottle 91 due to accidental activation of the operating mechanism 2 while extracting the medicine. Moreover, the design of the clamps 41, which change between the open and clamping states, can be used to grip medicine bottles of various sizes. Therefore, the clamping device of this invention is indeed a highly innovative and practical creation, effectively achieving the purpose of this invention.

[0036] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification shall still fall within the scope of the patent of the present invention.
