When a component is said to be "set" on another component, it can be directly set on the other component or it may be placed in a component.

[0093] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. The terms "vertical," "horizontal," "left," "right," "top," "bottom," and similar expressions used herein are for illustrative purposes only and are not intended to limit the application.

[0094] It is understood that when describing the parallel / perpendicular setup of two components, the included angle between the two components is allowed to have a tolerance of ±10% relative to the standard parallel / perpendicular setup.

[0095] An embodiment of this application provides an injection box, including a shell and a cover. The shell has a receiving cavity and a first opening communicating with the receiving cavity in a first direction, and the cover is flip-connected to the shell. The injection box also includes a supporting mechanism, an elastic mechanism, a linkage mechanism, and a locking mechanism. The supporting mechanism is used to carry the injection. The supporting mechanism is movably disposed in the receiving cavity along a first direction and moves between a first position and a second position, the first position being farther away from the first opening than the second position. The supporting mechanism also has a stop groove recessed along a second direction, the second direction being perpendicular to the first direction. The elastic mechanism is disposed in the receiving cavity and elastically supports the supporting mechanism along the first direction from the first position to the second position. The linkage mechanism is disposed between the supporting mechanism and the cover, and the linkage mechanism drives the cover to open the first opening during the movement of the supporting mechanism from the first position to the second position, or drives the cover to close the first opening during the movement of the supporting mechanism from the second position to the first position. The locking mechanism is at least partially movably connected to the shell along the second direction for extending into the stop groove to restrict the movement of the supporting mechanism from the first position to the second position.

[0096] In the aforementioned syringe cartridge, when the carrying mechanism is in the first position, the syringe carried by the carrying mechanism is located in the receiving cavity, and the cover seals the first opening, forming a sealed protective space within the receiving cavity. When the carrying mechanism is in the second position, the syringe carried by the carrying mechanism extends out from the first opening. A locking mechanism and an elastic mechanism work together to control the carrying mechanism to be in either the first or second position, and a linkage mechanism, driven by the carrying mechanism, synchronously controls the cover to seal or open the first opening. During use, only the locking mechanism needs to be operated to remove the syringe, and pressing the cover allows for easy storage, thus improving the convenience of using the syringe cartridge.

[0097] The following describes some embodiments of this application in detail with reference to the accompanying drawings.

[0098] Please refer to the following: Figure 1 and Figure 2 An embodiment of this application provides an injection box 100 for containing an injection 90. The injection box 100 includes a housing 10 and a cover 20. The housing 10 has a receiving cavity 10a and a first opening 10b communicating with the receiving cavity 10a in a first direction Z. The cover 20 is flip-connected to the housing 10 and is used to seal or open the first opening 10b.

[0099] Please refer to the following: Figure 3 and Figure 4The syringe cassette 100 also includes a support mechanism 30, an elastic mechanism 40, a linkage mechanism 50, and a locking mechanism 60. The support mechanism 30 carries the syringe 90. The support mechanism 30 is movably disposed in the receiving cavity 10a along a first direction Z and moves between a first position A and a second position B, where the first position A is farther from the first opening 10b than the second position B. Specifically, when the support mechanism 30 is in the first position A, the syringe 90 carried by the support mechanism 30 is located in the receiving cavity 10a, so that the cover 20 can seal the first opening 10b to form a sealed protective space in the receiving cavity 10a. When the support mechanism 30 is in the second position B, the syringe 90 carried by the support mechanism 30 extends out from the first opening 10b, facilitating the removal of the syringe 90. The support mechanism 30 also has a stop groove 30a recessed along a second direction X, where the second direction X is perpendicular to the first direction Z.

[0100] The elastic mechanism 40 is disposed in the receiving cavity 10a and elastically supports the bearing mechanism 30 along the first direction Z from the first position A to the second position B. The linkage mechanism 50 is disposed between the bearing mechanism 30 and the cover 20.

[0101] The linkage mechanism 50 drives the cover 20 to open the first opening 10b during the process of the carrying mechanism 30 moving from the first position A to the second position B, so that the needle 90 carried by the carrying mechanism 30 can extend out from the first opening 10b; or during the process of the carrying mechanism 30 moving from the second position B to the first position A, it drives the cover 20 to seal the first opening 10b, so that the receiving cavity 10a forms a sealed protective space.

[0102] The locking mechanism 60 is at least partially slidably connected to the housing 10 along the second direction X, for extending into the stop groove 30a to restrict the movement of the carrying mechanism 30 from the first position A to the second position B. It is understood that when the locking mechanism 60 extends into the stop groove 30a and disengages from the stop groove 30a, the carrying mechanism 30 is released from restriction and moves to the second position B under the elastic resistance of the elastic mechanism 40.

[0103] Understandably, during the use of the syringe box 100, pressing the cover 20 can cause the linkage mechanism 50 to move the bearing mechanism 30 from the second position B to the first position A, so that the locking mechanism 60 can extend into the stop groove 30a.

[0104] In the aforementioned syringe cassette 100, when the supporting mechanism 30 is in the first position A, the syringe 90 carried by the supporting mechanism 30 is located in the receiving cavity 10a, and the cover 20 seals the first opening 10b, forming a sealed protective space in the receiving cavity 10a. When the supporting mechanism 30 is in the second position B, the syringe 90 carried by the supporting mechanism 30 extends out from the first opening 10b. The locking mechanism 60 and the elastic mechanism 40 cooperate to control the supporting mechanism 30 to be in the first position A or the second position B, and the linkage mechanism 50, driven by the supporting mechanism 30, synchronously controls the cover 20 to seal or open the first opening 10b. During use, only the locking mechanism 60 needs to be operated to remove the syringe 90, and the cover 20 can be pressed to store the syringe 90, which improves the ease of use of the syringe cassette 100.

[0105] Please continue reading. Figure 3 and Figure 4 In some embodiments, the locking mechanism 60 includes a control lever 61, a locking lever 62, and a transmission member 63. The control lever 61 is movably connected to the housing 10 along a first direction Z, the locking lever 62 is movably connected to the housing 10 along a second direction X, and the transmission member 63 is rotatably connected to the housing 10. The transmission member 63 connects between the control lever 61 and the locking lever 62, and is configured to synchronously drive the locking lever 62 to move along the second direction X when the control lever 61 moves along the first direction Z. The end of the locking lever 62 away from the transmission member 63 is used to extend into the stop groove 30a to restrict the movement of the bearing mechanism 30 from the first position A to the second position B. This arrangement allows one end of the control lever 61 to be exposed from the side of the housing 10 with the first opening 10b, thereby facilitating the operator to control the locking mechanism 60 from the side of the housing 10 with the cover 20 via the control lever 61, further improving the ease of use of the syringe box 100.

[0106] In some embodiments, the housing 10 includes a bottom wall 11, which is disposed opposite to a first opening 10b in a first direction Z. The bottom wall 11 has a communicating hole 111. The supporting mechanism 30 includes a supporting member 31 and a latching member 32. The supporting member 31 is used to support the syringe 90 and is movably disposed between the bottom wall 11 and the first opening 10b along the first direction Z. A first position A is configured as the position where the supporting member 31 is when it moves to the bottom wall 11. The latching member 32 is connected to the side of the supporting member 31 opposite to the first opening 10b, and a stop groove 30a is formed on the latching member 32. The latching member 32 passes through the communicating hole 111, and a locking rod 62 is connected to the side of the bottom wall 11 opposite to the supporting member 31, so as to facilitate direct observation of the positional relationship between the locking rod 62 and the stop groove 30a, further improving the ease of use of the syringe box 100.

[0107] Optionally, the second position B is configured as the position where the cover 20 is flipped to its limit position by the carrying mechanism 30 through the linkage mechanism 50.

[0108] Please refer to the following: Figure 4 and Figure 5 In some embodiments, the housing 10 further includes a first support member 12, which is connected to the side of the bottom wall 11 opposite to the support member 31. The first support member 12 and the connecting hole 111 are spaced apart along the second direction X. The first support member 12 is provided with a connecting groove 12a, in which the transmission member 63 is rotatably connected to improve the stability of the connection between the transmission member 63 and the housing 10. The control rod 61 and the locking rod 62 extend into the connecting groove 12a respectively to facilitate connection with the transmission member 63.

[0109] In some embodiments, the bottom wall 11 is provided with a groove 112 recessed along the first direction Z on the side opposite to the support member 31. The groove 112 is located between the connecting hole 111 and the connecting groove 12a. The locking rod 62 is slidably connected in the groove 112 to improve the stability of the locking rod 62 sliding along the second direction X.

[0110] Optionally, the housing 10 also includes a cover 14 for covering the opening of the slide groove 112 to support the locking rod 62 in the first direction Z, further improving the stability of the locking rod 62 sliding in the second direction X.

[0111] In some embodiments, the housing 10 further includes a second support member 13, which is connected to the side of the bottom wall 11 opposite to the support member 31. The second support member 13 and the first support member 12 are spaced apart along the second direction X, and a connecting hole 111 is located between the second support member 13 and the first support member 12. The first support member 12 and the second support member 13 are flush in the first direction Z and are used to connect an external device, thereby fixing the housing 10 to the external device. The external device may be, but is not limited to, a medical cart or an ambulance. It is understood that raising the bottom wall 11 by the first support member 12 and the second support member 13 also facilitates the formation of space on the side of the bottom wall 11 opposite to the support member 31 for the fastener 32 to move in the first direction Z.

[0112] Please refer to the following: Figure 4 and Figure 6In some embodiments, the housing is further provided with a sliding hole 10c, which extends from one side of the cover 20 to the connecting groove 12a. The sliding hole 10c and the receiving cavity 10a are spaced apart in the second direction X. The control lever 61 includes a lever body 611, a pressing part 612, and a limiting part 613. The lever body 611 is slidably connected to the sliding hole 10c. The pressing part 612 is connected to one end of the lever body 611 and is located on one side of the cover 20, so that the operator can control the locking mechanism 60 from the side of the housing 10 where the cover 20 is located through the pressing part 612, thereby improving the ease of use of the syringe 100. The limiting part 613 is connected to one end of the lever body 611 and faces the transmission member 63. Along the first direction Z, the projection of the sliding hole 10c is located within the projection range of either the pressing part 612 or the limiting part 613, so that the lever body 611 and the sliding hole 10c are limited and connected, thereby reducing the risk of the control lever 61 and the housing 10 disengaging. Furthermore, the above-mentioned configuration can increase the area of ​​the control lever 61 that the operator can press, thereby improving ease of use; and increase the contact area between the control lever 61 and the transmission component 63, thereby improving the stability of the connection.

[0113] Please continue reading. Figure 4 and Figure 6 In some embodiments, the transmission member 63 includes a rotating part 631, and a first transmission part 632 and a second transmission part 633 extending outward from the rotating part 631, with the first transmission part 632 and the second transmission part 633 arranged intersectingly. The rotating part 631 is connected to the housing 10. Specifically, the rotating part 631 has coaxially arranged rotating shafts 6311 on both sides. The connecting groove 12a includes two first groove walls 121 spaced apart in the third direction Y. The first direction Z, the second direction X, and the third direction Y are perpendicular to each other. Each first groove wall 121 has a connecting hole 1211, and the rotating shaft 6311 is rotatably engaged in the connecting hole 1211.

[0114] The end of the first transmission part 632 away from the rotating part 631 abuts against the control lever 61 in the first direction Z, specifically against the limiting part 613. The end of the second transmission part 633 away from the rotating part 631 abuts against the locking lever 62 in the second direction X. When the control lever 61 moves along the first direction Z, it drives the second transmission part 633 to rotate via the first transmission part 632, causing the second transmission part 633 to move along the second direction X, thereby driving the locking lever 62 to move along the second direction X.

[0115] Optionally, the extending direction of the first transmission part 632 is perpendicular to the extending direction of the second transmission part 633.

[0116] Please continue reading. Figure 4 and Figure 6In some embodiments, the locking rod 62 is provided with a limiting hole 62a extending through the first direction Z. The end of the second transmission part 633 away from the rotating part 631 extends into the limiting hole 62a. The limiting hole 62a includes a hole wall 621 adjacent to the control rod 61 in the second direction X, and the second transmission part 633 abuts against the hole wall 621. Specifically, the limiting hole 62a extends its length along the second direction X. The side of the second transmission part 633 facing the hole wall 621 is flat to facilitate abutting against the hole wall 621. The side of the second transmission part 633 away from the hole wall 621 is provided with a chamfered surface to reduce the risk of interference between the side of the second transmission part 633 away from the hole wall 621 and the limiting hole 62a when the locking rod 62 moves toward the stop groove 30a and drives the second transmission part 633 to rotate.

[0117] Please continue reading. Figure 4 and Figure 6 In some embodiments, the locking mechanism 60 further includes a reset member 64, which is disposed between the housing 10 and the locking rod 62, and elastically supports the locking rod 62 toward the stop groove 30a. Specifically, the reset member 64 is a reset spring, disposed in the connecting groove 12a, which includes a second groove wall 122 disposed in the second direction X. The opposing ends of the locking rod 62 and the second groove wall 122 are respectively provided with slots for holding the reset member 64, so as to improve the structural stability of the reset member 64 between the housing 10 and the locking rod 62.

[0118] During use, when the supporting mechanism 30 is in the first position A, the locking rod 62 extends into the stop groove 30a under the elastic action of the reset member 64, and the end of the control rod 61 adjacent to the cover 20 is in a protruding state. By pressing the control rod 61, the transmission member 63 is rotated clockwise, causing the second transmission part 633 to move away from the stop groove 30a along the second direction X. This causes the locking rod 62 to overcome the elastic force of the reset member 64 and disengage from the stop groove 30a along the second direction X. At this time, the supporting mechanism 30 is released from restriction and moves to the second position B under the elastic support of the elastic mechanism 40. By pressing the cover 20, the linkage mechanism 50 drives the bearing mechanism 30 to move from the second position B to the first position A. Under the elastic action of the reset member 64, the locking rod 62 extends into the stop groove 30a again, thereby driving the transmission member 63 to rotate counterclockwise, so that the first transmission part 632 has a movement amount along the first direction Z, thereby making the end of the control rod 61 adjacent to the cover 20 in a protruding state.

[0119] Please refer to the following: Figure 7 and Figure 8In some embodiments, the support member 31 has a receiving groove 31a on the side facing the first opening 10b. The support mechanism 30 also includes a plurality of protective members 33, which are arranged along the second direction X in the receiving groove 31a. Each protective member 33 has a retaining groove 33a for holding the needle 90. The protective members 33 protect the needle 90 and reduce the risk of damage to the needle 90. Optionally, the retaining groove 33a is configured to conform to the shape of the needle 90 to improve the stability of the connection between the protective member 33 and the needle 90.

[0120] In some embodiments, the receiving groove 31a includes a first inner wall 311 and a second inner wall 312 disposed opposite to each other along a second direction X, with the first inner wall 311 being away from the control lever 61 and the second inner wall 312 being adjacent to the control lever 61. A plurality of protective members 33 are held between the first inner wall 311 and the second inner wall 312 along the second direction X. The first inner wall 311 has an inclined surface 3111 at one end facing the first opening 10b to facilitate the sliding of the protective members 33 into the receiving groove 31a.

[0121] In use, the aforementioned syringe cassette 100 extends from the first inner wall 311 along the second direction X toward the second inner wall 312, defined as a left-to-right direction. The syringes 90 in the multiple protective members 33 are arranged from left to right in order of their expiration dates, gradually moving from furthest to closest. When adding syringes 90 to the receiving slot 31a, the protective member 33 containing the syringes 90 slides into the receiving slot 31a from the left, pushing the other protective members 33 in the receiving slot 31a to the right to achieve automatic replacement. This ensures that the syringes 90 in the receiving slot 31a are always arranged according to their expiration dates, following a first-in, first-out principle. Compared to traditional compartmentalized syringe cassettes where the remaining syringes need to be manually moved after removal, this significantly improves the ease of use of the syringe cassette 100.

[0122] Please refer to the following: Figure 9 In some embodiments, the protective member 33 includes a first end face 331 and a second end face 332 disposed opposite each other along a first direction Z, two third surfaces 333 disposed opposite each other along a second direction X, and two fourth surfaces 334 disposed opposite each other along a third direction Y. The slot 33a is recessed in the first end face 331, and the second end face 332 is used to contact the bottom wall of the receiving groove 31a.

[0123] Viewed along the third direction Y, the length of the first end face 331 in the second direction X is greater than the length of the second end face 332 in the second direction X. Correspondingly, each third surface 333 includes a first segment 3331 and a second segment 3332 connected sequentially in the first direction Z. The two first segments 3331 are connected to both sides of the first end face 331 and are arranged opposite each other. Each second segment 3332 extends obliquely from the end of the first segment 3331 away from the first end face 331 to one side of the second end face 332. When multiple protective members 33 are held between the first inner wall 311 and the second inner wall 312 along the second direction X, the first segments 3331 of the multiple protective members 33 abut against each other to improve the stability of the holding. When the syringe 90 is replenished into the receiving groove 31a, the second segments 3332 of the protective members 33 can easily be inserted into the receiving groove 31a.

[0124] Viewed along the second direction X, each fourth surface 334 has a protrusion 3341 on the side near the first end face 331. The protrusion 3341 is used to abut against the surface of the carrier 31 where the receiving groove 31a is provided. Firstly, this facilitates the removal of the protective member 33 from the receiving groove 31a. Secondly, it improves the stability of the protective member 33 in the receiving groove 31a. Optionally, the side of the protrusion 3341 opposite to the groove 33a has a concave surface 3342, which further facilitates the operator's handling.

[0125] Understandably, the concave surface 3342 can be covered with a friction layer such as rubber to improve the stability of the operator's handling.

[0126] Please refer to the following: Figure 10 In some embodiments, the elastic mechanism 40 includes a guide rod 41 and a compression spring 42. The guide rod 41 is connected to the receiving cavity 10a and extends along a first direction Z. The guide rod 41 passes through the support mechanism 30 to facilitate movement of the support mechanism 30 along the first direction Z under the guidance of the guide rod 41. The compression spring 42 is sleeved on the guide rod 41 and located between the support mechanism 30 and the housing 10 to stably support the support mechanism 30.

[0127] Specifically, the supporting mechanism 30 also includes two connecting members 34, which are arranged opposite each other on both sides of the supporting member 31 along the second direction X. Each connecting member 34 has a guide hole 341 extending through along the first direction Z. Correspondingly, there are two elastic mechanisms 40. One end of a guide rod 41 is connected to the bottom wall 11, and the other end passes through the guide hole 341. A compression spring 42 is sleeved on the guide rod 41 and located between the connecting member 34 and the bottom wall 11. Through the cooperation of the two connecting members 34 and the two elastic mechanisms 40, the force on both sides of the supporting member 31 is evenly distributed, improving the stability of the movement of the supporting member 31.

[0128] Please continue reading. Figure 10In some embodiments, the linkage mechanism 50 includes a connecting rod 51, one end of which is hinged to the supporting mechanism 30, and the other end is hinged to the cover 20. Specifically, one end of the connecting rod 51 is hinged to the connecting member 34, and the other end is hinged to the cover 20. When the supporting mechanism 30 is in the first position A, the connecting rod 51 drives the cover 20 to seal the first opening 10b; when the supporting mechanism 30 is in the second position B, the connecting rod 51 drives the cover 20 to open the first opening 10b.

[0129] Optionally, there are two connecting rods 51, which are arranged at intervals along the second direction X to improve the stability of the linkage between the bearing mechanism 30 and the cover 20.

[0130] Please see Figure 11 The embodiments of this application also provide an emergency rescue device 200, including a mobile body 80 and any of the syringes 100 described in the above embodiments. The syringe 100 is connected to the mobile body 80 to improve ease of use.

[0131] In some embodiments, the syringe 100 is connected to the movable body 80 via a first support 12 and a second support 13, thereby saving the steps of taking out and putting in the syringe during use and improving the convenience of use.

[0132] Optionally, the mobile body 80 may be, but is not limited to, an emergency trolley or ambulance.

[0133] In summary, in the aforementioned syringe cassette 100 and emergency device 200, when the supporting mechanism 30 is in the first position A, the syringe 90 carried by the supporting mechanism 30 is located in the receiving cavity 10a, and the cover 20 seals the first opening 10b, forming a sealed protective space in the receiving cavity 10a. When the supporting mechanism 30 is in the second position B, the syringe 90 carried by the supporting mechanism 30 extends out from the first opening 10b. The locking mechanism 60 and the elastic mechanism 40 work together to control the supporting mechanism 30 to be in the first position A or the second position B, and the linkage mechanism 50, driven by the supporting mechanism 30, synchronously controls the cover 20 to seal or open the first opening 10b. During use, only the locking mechanism 60 needs to be operated to remove the syringe 90, and the cover 20 can be pressed to store the syringe 90, which improves the ease of use of the syringe cassette 100.

[0134] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
