[0040] The multifunctional chair for blood drawing provided in this embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0041] See Figure 1-3This utility model provides a multifunctional chair for blood drawing, including a chair body 1 and a chest shielding mechanism. A first connecting plate 2 is fixed to the bottom of the armrest 101 on one side of the chair body 1. The chest shielding mechanism includes a storage box 3, a shielding plate 5, and an adjustment component. The storage box 3 is detachably and fixedly connected to the first connecting plate 2. The adjustment component is located inside the storage box 3 away from the backrest 102 of the chair body 1. The adjustment component is connected to the shielding plate 5. Under the action of the adjustment component, the shielding plate 5 can move up and down and flip relative to the storage box 3 to block the front of the chair body 1 or be stored in the storage box 3. The front of the chair body 1 refers to the chest area when the user is sitting on the chair. A lifter 21 is provided at the bottom of the chair body 1, allowing the chair body 1 to adjust its height.
[0042] Specifically, a first connecting plate 2 is fixed to the armrest 101 on one side of the chair body 1, and the storage box 3 is detachably and fixedly connected to the first connecting plate 2. The top of the storage box 3 has an opening, and the top of the storage box 3 is connected to a cover plate 4 via a hinge. The cover plate 4 can be flipped to open or close the opening. The cover plate 4 can be flipped away from the chair body 1 to open the opening. When the cover plate 5 is stored in the storage box 3, the adjustment components are completely located inside the storage box 3. The first connecting plate 2 and the armrest 101 can be an integral structure.
[0043] In the above embodiments, preferably, the shielding plate 5 is in the shape of a convex character.
[0044] In the above embodiments, preferably, see [reference needed]. Figure 3-4 The adjustment assembly includes a flip rod 9, a lifting rod 7, a sleeve 6, and a locking device 8. The sleeve 6 is fixed inside the storage box 3 at a position away from the backrest 102 of the chair body 1. The bottom end of the lifting rod 7 is inserted into the sleeve 6 and can rotate relative to it. An angle locking structure is provided between the lifting rod 7 and the sleeve 6. The angle locking structure can lock the angle when the lifting rod 7 drives the cover plate 5 to rotate from the direction placed inside the storage box 3 to the front of the chair body 1. The lifting rod 7 can move up and down relative to the sleeve 6 and is locked in position by the locking device 8. The cover plate 5 is fixedly connected to the flip rod 9. One end of the flip rod 9 is connected to the top end of the lifting rod 7 and the flip rod 9 can be flipped 180° relative to the lifting rod 7. That is, when the cover plate 5 is inside the storage box 3, it is facing down relative to the flip rod 9. After the flip rod 9 drives the cover plate 5 to rotate 180°, the cover plate 5 is facing up relative to the flip rod 9. In this way, after the lifting rod 7 drives the flip rod 9 to rotate a certain angle, the cover plate 5 can block the front of the chair body 1.
[0045] Specifically, a support 12 is fixed at the top of the lifting rod 7. The support 12 has a U-shaped structure. A connecting shaft 19 is fixed on the inner side of the support 12. One end of the flipping rod 9 is sleeved on the connecting shaft 19. The axis of the connecting shaft 19 is perpendicular to the axis of the lifting rod 7. Pads 20 are fixed on the bottom walls of the support 12 on both sides of the connecting shaft 19. When the flipping rod 9 rests on one of the pads 20, the flipping rod 9 is in a horizontal position.
[0046] In the above embodiment, when the baffle 5 is located inside the storage box 3, the center line of the flip rod 9 in the length direction is perpendicular to the axis of the lifting rod 7, and the flip rod 9 is placed horizontally. The orientation within the storage box 3 refers to... Figure 2 As shown, the partition 5 is located directly in front of the chair body 1, as indicated. Figure 5 As shown. The ability of the flip lever 9 to flip 180° relative to the lifting lever 7 means that the cover 5 rotates 180° from its position inside the storage box 3, so that the cover 5 faces upwards and can cover the user's chest.
[0047] In this application, there is a distance between the shield 5 and the lifting rod 7, so that when the shield 5 is in front of the user's chest, it does not affect the operation of the arm, and the arm can pass over the flipping rod 9 to perform the blood drawing operation.
[0048] In the above embodiments, preferably, see [reference needed]. Figure 4 and Figure 7 The angle locking structure includes a locking groove 11 and a locking block 10. The locking groove 11 is set on the inner wall of the sleeve 6, and the locking block 10 is fixed to the bottom of the side wall of the lifting rod 7. When the baffle 5 is stored in the storage box 3, the locking block 10 is located below the locking groove 11. The locking block 10 can only be inserted into the locking groove 11 from the bottom end after the lifting rod 7 drives the baffle 5 to rotate to the front of the chair and then moves upward.
[0049] In this application, when the cover plate 5 is stored in the storage box 3, the locking block 10 is located below the locking groove 11, so that the cover plate 5 can rotate between the locking block 10 and the locking groove 11 to adjust the position and angle of the cover plate 5, thereby achieving the purpose of being located directly in front of the chair body 1.
[0050] Specifically, the locking groove 11 is a strip-shaped structure. More specifically, two strip-shaped blocks are fixed on the side wall inside the sleeve 6, and the gap between the two strip-shaped blocks forms the locking groove 11. The number of locking grooves 11 can be one or two, and when there are two, they are evenly distributed along the circumference inside the sleeve 6. The number of locking blocks 10 is the same as the number of locking grooves 11, and they fit together one by one.
[0051] In one embodiment, the bottom end of the locking device 8 is provided with a groove, the inner wall of the groove is provided with threads, the top end of the locking device 8 is provided with a threaded hole communicating with the groove, the lifting rod 7 is provided with a first threaded segment, the locking device 8 is sleeved on the lifting rod 7 through the threaded hole and can be threadedly connected with the first threaded segment, and the top outer wall of the sleeve 6 is provided with a second threaded segment that can be threadedly connected with the groove. Figure 4 As shown, for example, the locking device 8 is cylindrical in shape.
[0052] In use, when the baffle 5 reaches the desired height, rotating the locking device 8 simultaneously connects it to the sleeve 6 of the lifting rod 7 via threads. This fixes the lifting rod 7, thus securing the baffle 5. Loosening the locking device 8 in the opposite direction allows for height adjustment of the baffle 5, thus achieving height adjustment functionality to suit different user needs. When the baffle 5 is stored in the storage box 3, the outer wall of the lifting rod 7 exposed on the sleeve 6 has no threads; that is, the first threaded section is located inside the sleeve 6.
[0053] In one embodiment, see Figure 10 The cover plate 4 has a U-shaped notch 13 that allows the lifting rod 7 to pass through. A cap 14 is rotatably connected to the top of the cover plate 4 around the U-shaped notch 13. The cap 14 can cover or open the U-shaped notch 13 by rotating itself. When the lifting rod 7 extends out of the storage box 3, the U-shaped notch 13 is designed so that the cover plate 4 can cover the storage box 3. When the cover plate 4 is flipped over to cover the opening, the U-shaped notch 13 fits onto the lifting rod 7, so that the lifting rod 7 does not prevent the cover plate 4 from covering the opening.
[0054] In one embodiment, see Figure 11-13 A second connecting plate 15 is fixed to the bottom of the armrest 101 on the other side of the chair body 1. A support plate is detachably fixed to the second connecting plate 15. A detachable storage basket 16 is suspended on the side wall of the support plate facing away from the chair body 1.
[0055] Specifically, at least two parallel hanging rings 17 are fixed on the side wall of the support plate facing away from the chair body 1, and hooks 18 that cooperate with the hanging rings 17 are fixed on the outer side wall of the storage basket 16. The storage basket 16 is suspended on the side of the chair body 1 by hanging the hooks 18 on the hanging rings 17.
[0056] Regarding the connection method between the first connecting plate 2 and the storage box 3, and between the second connecting plate 15 and the support plate, this application does not make specific limitations. For example, a bolt and nut connection method can be used for detachable fixed connection. Both the first connecting member and the second connecting member are provided with connection holes for connection.
[0057] The following example illustrates the specific usage of the chest covering mechanism by taking the cover 5 out of the storage box 3 and placing it in front of the chair body 1.
[0058] See Figure 3 , Figure 5-6 and Figure 9 The initial state of the shield 5 is that it is stored in the storage box 3, such as... Figure 3 As shown, first flip the cover 4 to the open side, then manually grasp the flipping lever 9 and pull the cover 5 upwards. When part of the cover 5 is outside the storage box 3, flip the cover 5 to make the flipping lever 9 stand upright, as shown. Figure 5 As shown, the lifting rod 7 is then rotated to align the locking block 10 with the locking groove 11. The lifting rod 7 is then moved upwards to move the baffle 5 upwards, and the locking block 10 is inserted into the locking groove 11. At this point, the lifting rod 7 cannot rotate relative to the sleeve 6. Figure 6 As shown, the partition 5 is then flipped upwards so that it is directly in front of the chair body 1. During this process, the partition 5 is flipped 180°. Figure 9 As shown, if the user is sitting in a chair, with the cover 5 positioned directly in front of their chest, then manually rotate the locking device 8 to simultaneously connect the locking device 8 to the lifting rod 7 and the sleeve 6, until the locking device 8 can no longer rotate. At this point, the lifting rod 7 is connected to the sleeve 6 via the locking device 8, and the lifting rod 7 cannot move up or down relative to the sleeve 6. This completes the process of removing the cover 5 from the storage box 3 and rotating it to the user's chest. In order for the cover 4 to be placed back on the storage box 3, rotate the sealing cover 14 to expose the U-shaped notch 13. Thus, when the cover 4 is placed on the storage box 3, the lifting rod 7 is located within the notch and does not obstruct the cover 4.
[0059] This invention features a retractable or expandable shield on the armrest of a chair. When drawing blood from a patient, the shield covers the chest of the medical staff, preventing the patient's arm from frequently touching the chest of the staff member opposite them, thus improving the comfort of the medical staff. Furthermore, when not in use, the shield can be stored in a storage box, reducing space occupation, allowing the chair to be moved freely, meeting hospital requirements for keeping the work surface clean and tidy, and also serving as a dust barrier. When retracted, the chest shielding mechanism designed in this application is located on one side of the chair body, not affecting sitting on the chair, conforming to ergonomic standards and meeting comfort requirements.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
