[0090] FIGS. 8 (A) to (C) illustrates a first armrest (310). Referring to FIGS. 8 (A) to (C), the first armrest (310) may include a first inner pad (311) and a first outer pad (312). The first inner pad (311) may be positioned further inward than the first outer pad (312). The first inner pad (311) and the first outer pad (312) may be foldably coupled. The first inner pad (311) and the first outer pad (312) may be folded (see FIGS. 8 (A), (C)) or unfolded (see FIGS. 8 (B)). The first inner pad (311) and the first outer pad (312) may have a rectangular shape with a long side in the front-rear direction.

[0091] Based on (A) of FIG. 8, the first inner pad (311) may include an upper surface (3111), a lower surface (3112) located opposite the upper surface (3111), a front surface (3113) connecting the upper surface (3111) and the lower surface (3112), a rear surface (3114) connecting the upper surface (3111) and the lower surface (3112), a first side surface (3115) connecting the inner end of the upper surface (3111) and the lower surface (3112), and a second side surface (3116) connecting the outer end of the upper surface (3111) and the lower surface (3112). Based on (A) of FIG. 8, the first outer pad (312) may include an upper surface (3121), a lower surface (3122) located opposite the upper surface (3121), a front surface (3123) connecting the upper surface (3121) and the lower surface (3122), a rear surface (3124) connecting the upper surface (3121) and the lower surface (3122), a first side surface (3125) connecting the inner end of the upper surface (3121) and the lower surface (3122), and a second side surface (3126) connecting the outer end of the upper surface (3121) and the lower surface (3122).

[0092] Referring to FIG. 8 (A), the first inner pad (311) and the first outer pad (312) can be foldably combined. When the first inner pad (311) and the first outer pad (312) are folded, the first side (3115) of the first inner pad (311) and the first side (3125) of the first outer pad (312) can face each other. When viewed from the front (3113, 3123) of FIG. 8 (A), the first inner pad (311) can be unfolded to the right (RS), and the first outer pad (312) can be unfolded to the left (LS). Referring to (B) of FIG. 8, when the first inner pad (311) and the first outer pad (312) are unfolded, the first side (3115) of the first inner pad (311) is exposed upward, and the first side (3125) of the first outer pad (312) can be exposed upward.

[0093] Referring to (C) of FIG. 8, at least one hinge (340) may be provided on the lower surface (3112) of the first inner pad (311) and the lower surface (3122) of the first outer pad (312). The first inner pad (311) and the first outer pad (312) may be folded or unfolded by the hinge (340) on the lower surfaces (3112, 3122). The unfolded state may be referred to as the extended state. The hinge (340) may be a torque hinge.

[0094] When the first inner pad (311) and the second inner pad (312) are in an extended state, the first armrest (310) may have an optimal width to support a blood collection pillow. For example, when extended, the width of the first armrest (310) in the left-right direction may be at least 16 cm, and in this case, it can easily support a blood collection pillow having a width of 20 cm. When the first inner pad (311) and the second inner pad (312) are in a folded state, the width of the first armrest (310) in the left-right direction may be at least 8 cm. The second armrest (320) may also have the same width.

[0095] Referring again to FIGS. 6 and 7, the second armrest (320) may include a second inner pad (321) and a second outer pad (322). The second inner pad (321) may be positioned further inward than the second outer pad (322). The second inner pad (321) and the second outer pad (322) may be foldably coupled. The second inner pad (321) and the second outer pad (322) may be folded (see FIG. 6) or unfolded (see FIG. 7). The second inner pad (321) and the second outer pad (322) may have a rectangular shape with a long side in the front-rear direction. When viewed from the front in FIGS. 6 and 7, the second inner pad (321) may be unfolded to the left (LS), and the second outer pad (322) may be unfolded to the right (RS).

[0096] The first armrest (310) and the second armrest (320) are symmetrical with respect to the front-rear axis, and the configuration described in the first armrest (310) may also be applied to the second armrest (320). Accordingly, the second inner pad (321) may include an upper surface, a lower surface, a front surface, a rear surface, a first side surface, and a second side surface, and the description thereof is substituted with the description of the first inner pad (311) of the first armrest (310). The second outer pad (322) may include an upper surface, a lower surface, a front surface, a rear surface, a first side surface, and a second side surface, and the description thereof is substituted with the description of the first inner pad (311) of the first armrest (310). At least one hinge (340) may be provided on the lower surface of the second inner pad (321) and the lower surface of the second outer pad (322). The second inner pad (321) and the second outer pad (322) can be folded or unfolded by means of a hinge (340) on the lower surface. The unfolded state can be referred to as the extended state.

[0097] Referring again to FIGS. 1a and 1b, the blood collection chair (10) may include an angle adjuster (700). The angle adjuster (700) may connect the backrest (200) and the armrest (300). The angle adjuster (700) may adjust the angle of the armrest (300) relative to the backrest (200). The angle adjuster (700) may be provided on the left side and the right side of the backrest (200), respectively. Accordingly, the angles of the first armrest (310) and the second armrest (320) may be adjusted independently. Below, the process of adjusting the angle of the first armrest (310) by the angle adjuster (700) is described, but this can be applied in the same way to the angle adjustment of the second armrest (320).

[0098] FIGS. 9 to 12 are drawings illustrating the process of adjusting the angle of the armrest (300) of a blood collection chair (10) according to an embodiment of the present disclosure.

[0099] The angle adjuster (700) may include a first coupling frame (710). The first coupling frame (710) may include at least one hole penetrating the first coupling frame (710) in the left-right direction. A fastener may be fixed to the backrest (200) by passing through at least one hole of the first coupling frame (710).

[0100] The angle adjuster (700) may include a second coupling frame (720). The second coupling frame (720) may be rotatably coupled to the first coupling frame (710). For example, the second coupling frame (720) may be connected to the first coupling frame (710) by a pin or shaft, so that it may be rotatable to the first coupling frame (710) when adjusting the angle.

[0101] The angle adjuster (700) may include an adjustment unit (730). The adjustment unit (730) may perform the function of fixing or changing the angle between the first coupling frame (710) and the second coupling frame (720). The adjustment unit (730) may be designed to include a ratchet mechanism or a gear inside so as to be fixed at various angles.

[0102] The angle adjuster (700) may include a lever (740). One end of the lever (740) is connected to the adjustment part (730), and the other end may be exposed to the outside of the angle adjuster (700). The lever (740) can unlock or lock the adjustment part (730). When a user presses the lever (740), the adjustment part (730) may be unlocked. In this state, after the user adjusts the angle of the first armrest (310) to a desired position, if the user releases the lever (740) that was being pressed, the adjustment part (730) may be locked again.

[0103] For example, the angle adjuster (700) may be able to adjust the angle of the first armrest (310) in three steps: a first angle (A1), a second angle (A2), and a third angle (A3). The second angle (A2) may be larger than the first angle (A1), and the third angle (A3) may be larger than the second angle (A2). Referring to FIGS. 9 and 10, the first armrest (310) may be adjusted downward to have a first angle (A1) relative to the first armrest (310) in a horizontal state. At this time, the first angle (A1) may be approximately 10°. Referring to FIGS. 9 and 11, the first armrest (310) may be adjusted downward to have a second angle (A2) relative to the first armrest (310) in a horizontal state. At this time, the second angle (A2) may be approximately 15°. Referring to FIGS. 9 and FIGS. 12, the first armrest (310) can be adjusted downward to have a third angle (A3) with respect to the first armrest (310) in a horizontal state. At this time, the third angle (A3) may be approximately 20°. However, it is not limited thereto, and the first armrest (310) can be adjusted to various angles. In addition, the first armrest (310) can be adjusted to rotate upward as well as to be adjusted downward.

[0104] The angle adjustment of the armrest (300) can provide convenience and stability during blood collection.

[0105] The blood collection chair (10) of the present disclosure is configured to allow the angle of the armrest (300) to be adjusted in various ways, thereby optimizing the position of the arm according to the patient's body type (body size, arm length, blood collection location) and condition, and thus allowing blood collection to be performed more smoothly. For example, by adjusting the angle, blood flow visibility can be improved, blood flow can be improved, and it can be applied to various body types.

[0106] The first angle (A1) is suitable for standard blood collection and can provide a stable and comfortable position for most patients. The second angle (A2) is an angle adjusted downward compared to the first angle (A1) and can improve vein visibility in patients where veins are difficult to see. The third angle (A3) is an angle adjusted downward compared to the second angle (A2) and can improve vein visibility in patients where veins are difficult to find, such as obese patients or patients with deep veins.

[0107] FIG. 13 is a drawing for showing the coupling position of the angle adjuster (700) of the blood collection chair (10) according to an embodiment of the present disclosure.

[0108] Referring to FIG. 13, the second armrest (320) may further include a coupling portion (323). If the coupling portion (323) is located at the rear end of the second inner pad (321) and the second outer pad (322), it may be structurally connected to the second inner pad (321) and the second outer pad (322). However, the coupling portion (323) may not be foldable. The coupling portion (323) may be a part that is coupled to the second coupling frame (720) of the angle adjuster (700). Depending on the size and position of the angle adjuster (700), at least a portion of the coupling portion (323) may overlap with the right side of the backrest (200) in the left and right directions. The second coupling frame (720) of the angle adjuster (700) may be coupled to the inside of the coupling portion (323). Alternatively, the second coupling frame (720) may be coupled to the side facing the right side of the backrest (200) where the coupling portion (323) is coupled. When the second coupling frame (720) is rotated relative to the first coupling frame (710), the coupling portion (323) and the second inner pad (321) and second outer pad (322) structurally connected to the coupling portion (323) may be rotated together.

[0109] Although only the second armrest (320) is described in FIG. 13, this description can be applied equally to the first armrest (310). The first armrest (310) may include a coupling part (313), and the second coupling frame (720) of the angle adjuster (700) may be coupled to the coupling part (313) of the first armrest (310).

[0110] FIG. 14 is a drawing illustrating another embodiment of a means for adjusting the angle of an armrest (300) of a blood collection chair (10) according to an embodiment of the present disclosure.

[0111] In the above description, the angles of the first armrest (310) and the second armrest (320) are independently adjusted through the angle adjuster (700). However, this is not limited thereto, and the first armrest (310) and the second armrest (320) can be adjusted together in conjunction. For example, referring to FIG. 14, the shaft (330) can adjust the angles of the first armrest (310) and the second armrest (320) simultaneously in conjunction. One end of the shaft (330) can be connected to the coupling part (313) of the first armrest (310), and the other end of the shaft (330) can be connected to the coupling part (323) of the second armrest (320). As the shaft (330) rotates, the first and second armrests (310, 320) can rotate together.

[0112] FIG. 15 is a drawing illustrating the process of moving the armrest (300) of a blood collection chair (10) left and right according to an embodiment of the present disclosure.

[0113] Referring to (A) and (B) of FIG. 15, the first and second armrests (310, 320) can be moved to the right relative to the connecting part (313, 323) in addition to angle adjustment. Referring to (A) and (B) of FIG. 15, the first and second armrests (310, 320) can be moved to the left relative to the connecting part (313, 323) in addition to angle adjustment. The left and right movement of the armrest (300) can accommodate various body types of patients. Additionally, the armrest (300) can be moved left and right according to the arrangement of medical staff or equipment to efficiently utilize the workspace. A rail system, an actuator, or the like can be used for the left and right movement of the armrest (300).

[0114] FIGS. 16 and 17 are drawings illustrating a fall prevention means for a blood collection chair (10) according to an embodiment of the present disclosure and a combined position of the fall prevention means and the blood collection chair (10).

[0115] The blood collection chair (10) may be equipped with a fall prevention means to prevent the patient from falling during blood collection. For example, the fall prevention means may be a belt (810). The belt (810) may be detachably attached to the chair (10). A clip may be provided at one end of the belt (810), and a receiver may be provided at the other end of the belt (810). The clip may be secured by being inserted into the receiver. The belt (810) may further include a length adjustment member that can adjust the length of the belt (810).

[0116] Referring to (A) of FIG. 16, a first attachment portion (820) may be provided on the inner surface of the belt (810). Referring to (B) of FIG. 16, a second attachment portion (830) may be provided on the rear surface of the backrest (200). Referring to (A) of FIG. 17, the belt (810) may be attached to the chair (10) by attaching the first attachment portion (820) to the second attachment portion (830). Referring to (B) of FIG. 17, the clip and receiver of the belt (810) may be positioned near the seat plate (100) of the chair (10). By attaching the belt (810) while sitting, the user can prevent falling during blood collection.

[0117] The chair (10) of the present disclosure can be used for office work or similar purposes in normal times, and a belt (810) can be attached to the chair (10) to prevent falls during blood collection. Additionally, the belt (810) can be removed from the chair (10) after blood collection is finished.
