DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] Figures 1-6 This is a schematic diagram of the structure of the blood collection auxiliary device provided in the embodiment of the present application, as shown in FIG. Figures 1-6 As shown, the blood collection auxiliary device may include: a base body 1, a pillow cover unwinding chamber 2, a pillow cover rewinding chamber 3, a first driving mechanism 4 and a belt unwinding chamber 5.

[0042] The seat 1 can be used to place the user's arm so that the user's arm can be used to draw blood on the seat 1. The pillow towel unwinding chamber 2 can be used to place a pillow towel 101. The pillow towel 101 in the pillow towel unwinding chamber 2 is released and transported to the pillow towel rewinding chamber 3. Then, the pillow towel rewinding chamber 3 can rewind the pillow towel 101 in the pillow towel unwinding chamber 2.

[0043] The first driving mechanism 4 can be used to drive the pillow cover 101 from the pillow cover unwinding chamber 2 through the upper surface of the base 1 and then be rolled up into the pillow cover rolling chamber 3.

[0044] The tape unwinding chamber 5 is used to output the tape 102 to the outside of the base 1 to the tape output port 6 provided on the wall of the base 1 .

[0045] Furthermore, when the blood collection auxiliary device is put into use, a control circuit board and / or control buttons may be provided to facilitate corresponding electric control operations of various components.

[0046] The blood collection auxiliary device provided in this embodiment includes a base, a pillow cover unwinding chamber, a pillow cover rewinding chamber, a first drive mechanism, and a belt unwinding chamber. The first drive mechanism drives the pillow cover from the pillow cover unwinding chamber through the upper surface of the base and then rewinds it into the pillow cover rewinding chamber. The belt unwinding chamber is used to output the belt outside the base to a belt output port provided on the wall of the base. Thus, the blood collection auxiliary device has a cuff belt disposed between the pillow cover unwinding chamber and the pillow cover rewinding chamber. When using the blood collection auxiliary device for blood collection, a nurse can directly remove the belt from the belt unwinding chamber, thereby improving the convenience and efficiency of blood collection.

[0047] In some embodiments of the present application, the blood collection auxiliary device mentioned in the above embodiments is further introduced, such as Figure 4 As shown, the blood collection auxiliary device may further include a cutting mechanism 7 .

[0048] Specifically, the cutting mechanism 7 can be used to cut the belt 102 at the belt output port 6 .

[0049] It is understandable that the setting of the cutting mechanism 7 facilitates the output and cutting of the belt body 102, and it is easy to use so that the staff does not need to get the belt body 102 from other places, thereby improving the efficiency of blood collection.

[0050] Furthermore, the cutting mechanism 7 comprises a cutter / spike 71. The cutter / spike can be used to cut / stab the strip 102 at the strip outlet.

[0051] Furthermore, the cutting mechanism 7 may be provided with an electric retractor 72. The electric retractor 72 may be used to drive the cutter / spiking member 71 to cut / pierce the belt 102 at the belt outlet 6.

[0052] The electric retractor 72 may be a linear motor, which drives the cutter / spike 71 to retract and retract.

[0053] For example, when using the belt, the operator can tension the output belt segment toward the cutter / spike 71 to cut / sever the belt segment, or use the electric retractor 72 to electrically cut / sever the belt segment at the belt output port 6. Therefore, no matter which method is used to cut the belt segment at the belt output port 6, it is convenient to use.

[0054] In some embodiments of the present application, the blood collection auxiliary device mentioned in the above embodiments is further introduced, such as Figure 6 As shown, the seat body 1 is provided with a detachably mounted bottom shell member 12 and a detachably mounted upper shell member 13 .

[0055] Specifically, the bottom shell 12 and the upper shell 13 can be used to separate the pillow cover unwinding chamber 2, the pillow cover rewinding chamber 3 and the belt unwinding chamber 5.

[0056] The upper shell 13 can be mounted on the bottom shell 12, and a tape unwinding cavity 5 is formed between the bottom shell 12 and the upper shell 13. Figure 6 As shown, the left and right sides of the upper end of the upper shell 13 are concave downward to form corresponding pillow towel unwinding cavities 2 and 3.

[0057] It can be understood that the arrangement of the bottom shell 12 and the upper shell 13 separates the pillow towel unwinding chamber 2, the pillow towel rewinding chamber 3 and the belt unwinding chamber 5, which facilitates the overall layout and implementation of the blood collection auxiliary device, and the bottom shell 12 and the upper shell 13 are both detachable to facilitate the loading of the belt 102 and the replacement operation after use.

[0058] In some embodiments of the present application, the blood collection auxiliary device mentioned in the above embodiments is further introduced, such as Figure 4 and Figure 5 As shown, the seat body 1 is provided with a second driving mechanism 8 for driving the belt body 102 to output.

[0059] The second driving mechanism 8 includes a second motor 81 and a second rotating body 82 .

[0060] Specifically, the second motor 81 can be used to drive the second rotating body 82 to rotate the belt body 102 to generate friction output.

[0061] It is understandable that since the second motor 81 can automatically drive the second rotating body 82 to drive the belt body 102 to rotate and output friction, there is no need for staff to pull the belt body 102 for output. It can be seen that the blood collection auxiliary device is convenient and practical.

[0062] In some embodiments of the present application, the blood collection auxiliary device mentioned in the above embodiments is further introduced, such as Figure 1 and Figure 2 As shown, the base body 1 is provided with a first cover body 21 and a second cover body 31 .

[0063] The first cover 21 is used to open / close the pillow towel unwinding chamber 2. The second cover 31 is used to open / close the pillow towel rewinding chamber 3. A recess 9 is formed between the first cover 21 and the second cover 31 for the pillow towel 101 to pass through.

[0064] It can be understood that the arrangement of the first cover 21 and the second cover 31 allows the pillow towel unwinding chamber 2 and the pillow towel rewinding chamber 3 to be opened / closed, which facilitates the loading of the pillow towel 101 and the replacement operation after use.

[0065] It can be understood that the setting of the concave position 9 has a reminder function, specifically it can remind the user to place the arm in the concave position 9.

[0066] Furthermore, the recessed portion 9 is provided with a pad 10 for padding the pillow cover 101 so as to pad the arm placed on the pillow cover 101 .

[0067] It can be understood that the cushion block 10 cushions the arm so that the user's arm is not likely to come into contact with other positions of the seat body 1 .

[0068] Furthermore, forward and backward pressing rollers 11 are provided on the first cover body 21 side and the second cover body 31 side of the recess 9 .

[0069] The forward and backward pressing rollers 11 are used to press the pillow cover 101 against or release it from the cushion block 10 during rolling.

[0070] In some embodiments of the present application, the blood collection auxiliary device mentioned in the above embodiments is further introduced, such as Figure 3 and Figure 4 As shown, the first driving mechanism 4 includes a first motor 41 and a first rotating body 42 .

[0071] Specifically, the first motor 41 can be used to drive the first rotating body 42 to roll up the pillow towel 101 in the pillow towel rolling chamber 3.

[0072] It can be understood that when the first rotating body 42 rotates, it can drive the pillow towel rolling chamber 3 to collect the pillow towel 101 in the pillow towel unwinding chamber 2.
