Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a blood collection box. Background Art

[0002] In medical blood collection, the traditional blood collection process often requires medical staff to manually wrap a cuff around the patient to promote venous filling and facilitate blood collection. This process consumes a lot of time and energy for medical staff when facing a large number of people who need blood collection. For example, during large-scale physical examination activities, community centralized blood collection services, or busy blood collection hours in hospitals, medical staff need to frequently wrap and remove the cuff for different patients. Manual operation is not only relatively inefficient, but also long-term repetitive labor can easily lead to fatigue of medical staff, increase work pressure, and even cause operational errors due to fatigue. Summary of the invention

[0033] Examples, such as Figure 1-Figure 7As shown, a blood collection box includes a box body 100, the box body 100 includes a placement cover 110 and an operating cover 120 hinged to the placement cover 110, the operating cover 120 is provided with an extension mechanism 200 and a binding mechanism 300, the extension mechanism 200 includes a side plate 210 constituting the operating cover 120, the side plate 210 is provided with a plug hole 211 for inserting an arm; the binding mechanism 300 includes a rubber belt 310 arranged in a ring shape in the plug hole 211, the two ends of the rubber belt 310 are respectively inserted into the side plate 210, an elastic drawstring 311 is connected between the ring part of the rubber belt 310 and the inner wall of the plug hole 211, after the arm is inserted into the middle part of the ring part of the rubber belt 310, the two ends of the rubber belt 310 are separated from each other, so that the rubber belt 310 is tightened around the arm.

[0034] The working mechanism of the blood collection box provided in this embodiment is as follows:

[0035] When drawing blood, the arm is inserted into the insertion hole 211, and the rubber band 310 in the insertion hole 211 is placed in a ring shape. After the arm is inserted into the ring-shaped rubber band 310, the rubber band 310 is wound around the arm, and then the two ends of the rubber band 310 are separated from each other, so that the rubber band 310 is tightly wound around the arm, thereby replacing the step of manually winding the compression cuff, and can reduce the burden of medical staff when drawing blood from a large number of people;

[0036] There are three elastic pull cords 311 , which are respectively arranged at the nine o'clock, twelve o'clock and three o'clock positions of the annular rubber belt 310 , so as to ensure that the rubber belt 310 can maintain the annular state.

[0037] Regarding the structure of the strapping mechanism 300, specifically:

[0038] The strapping mechanism 300 also includes two active cylinders 320 and two piston cylinders 350 connected to the two active cylinders 320 through two first air pipes 340. Piston plates 360 are slidably connected in the two piston cylinders 350. The two ends of the rubber belt 310 are respectively connected to the two piston plates 360. When the active cylinder 320 is extended, the piston plate 360 ​​slides into the corresponding piston cylinder 350, thereby tightening the rubber belt 310. When the active cylinder 320 is shortened, the rubber belt 310 is relaxed, and the elastic pull rope 311 pulls the rubber belt 310 away from the arm.

[0039] When the active cylinder 320 is extended, the gas in the piston cylinder 350 is extracted through the first air pipe 340, so that the piston plate 360 ​​slides into the piston cylinder 350, so that the rubber belt 310 connected to the piston plate 360 ​​is pulled. Since two piston cylinders 350 and two piston plates 360 are provided, and are symmetrically located on both sides of the insertion hole 211, the two ends of the rubber belt 310 are pulled. After the blood drawing needle is inserted into the blood vessel, the active cylinder 320 is controlled to shorten, and the gas in the active cylinder 320 is released into the piston cylinder 350. At this time, the piston plate 360 ​​is pushed, so that the two piston plates 360 approach each other, so that the rubber belt 310 is released. At this time, the elastic pull rope 311 pulls the rubber belt 310 to expand the diameter of the ring formed by the rubber belt 310, so that the rubber belt 310 is away from the arm, so that blood can be drawn subsequently, and the arm can be pulled away from the insertion hole 211 after blood drawing.

[0040] Regarding the structure of the driving mechanism 400, specifically:

[0041] The driving mechanism 400 includes a mounting block 410, the active cylinder 320 is connected inside the mounting block 410, a placement seat 420 is vertically slidably connected inside the mounting block 410, a first spring 430 is arranged between the placement seat 420 and the mounting block 410, the placement seat 420 is connected to the cylinder rod 330 of the active cylinder 320, and when the blood collection tube is placed on the placement seat 420 and pressed down, the active cylinder 320 extends.

[0042] After the arm penetrates deeply into the insertion hole 211, the blood collection tube is placed on the placement seat 420. The blood collection tube presses the placement seat 420 to move downward, so that the placement seat 420 drives the cylinder rod 330 to move downward, so that the active cylinder 320 extends, so that the active cylinder 320 extracts the air in the piston tube 350, and after releasing the pressure on the placement seat 420, the first spring 430 can lift the placement seat 420, so that the placement seat 420 moves upward, thereby shortening the active cylinder 320.

[0043] Among the optional methods of this embodiment, the more preferred ones are:

[0044] The driving mechanism 400 also includes a control frame 440, the sliding direction of the control frame 440 is perpendicular to the sliding direction of the placement seat 420, and a second spring 450 is connected between the control frame 440 and the mounting block 410; it also includes a pressure control mechanism 500, the pressure control mechanism 500 includes a circular plate 510, an elastic block 520 is connected between the circular plate 510 and the placement seat 420, a connecting frame 421 is connected between the circular plate 510 and the cylinder rod 330, a pawl is arranged on the connecting frame 421, and a ratchet that cooperates with the pawl is arranged on the control frame 440.

[0045] When the placement seat 420 moves downward, it drives the circular plate 510 to move downward synchronously. At this time, the connecting frame 421 moves downward synchronously, so that the pawl on the connecting frame 421 can move downward unidirectionally on the ratchet on the control frame 440. At this time, the pawl pushes the control frame 440 to slide back and forth a small amount. The elastic force of the second spring 450 can make the pawl clamped on the ratchet, ensuring that the position of the placement seat 420 after moving downward can remain stable, thereby ensuring the firmness of the rubber belt 310. After inserting the needle into the blood vessel, the control frame 440 is manually pressed to compress the second spring 450, so that the pawl moves away from the ratchet. At this time, the first spring 430 extends to lift the placement seat 420, so that the active cylinder 320 is shortened, thereby relaxing the rubber belt 310.

[0046] Among the optional methods of this embodiment, the more preferred ones are:

[0047] A first connecting rod 530 is hinged on the placement seat 420, a second connecting rod 540 is hinged on the circular plate 510, the first connecting rod 530 is connected to a sliding rod 531, and the second connecting rod 540 is provided with a sliding groove that cooperates with the sliding rod 531. When the rubber belt 310 is tied tightly to the arm, the elongation resistance of the cylinder rod 330 increases, so that the elastic block 520 is compressed, so that the circular plate 510 is close to the placement seat 420, so that the second connecting rod 540 abuts against the control frame 440, so that the ratchet prevents the pawl from moving downward.

[0048] When the placement seat 420 moves downward, the placement seat 420 applies pressure to the circular plate 510 through the elastic block 520, and the circular plate 510 further applies pressure to the first spring 430. When the rubber belt 310 is tied tightly on the arm, the extension of the cylinder rod 330 is hindered, so that the pressure applied by the placement seat 420 to the elastic block 520 increases, causing the elastic block 520 to be deformed under pressure, so that the placement seat 420 and the circular plate 510 approach each other, causing the first connecting rod 530 and the second connecting rod 540 to swing relative to each other, so that the sliding rod 531 slides in the sliding groove on the second connecting rod 540, causing the second connecting rod 540 to swing and be able to abut against the control frame 440, so that the ratchet and the pawl are tightly abutted, thereby hindering the downward movement of the connecting frame 421. At this time, the rubber belt 310 is no longer tightened on the arm, preventing the rubber belt 310 from being overly tightened on the arm.

[0049] Among the optional methods of this embodiment, the more preferred ones are:

[0050] The box body 100 further includes a placement block 111 , which is connected to the placement cover 110 , and has a plurality of placement holes 112 for placing blood collection tubes.

[0051] The blood collection tube to be used is placed in the placement hole 112 on the placement block 111. If blood has not been collected in the blood collection tube, when the box body 100 is closed, either the placement cover 110 or the operation cover 120 can be located at the upper part. If blood has been collected in the blood collection tube, the placement cover 110 should be located at the lower part when the blood collection tube is placed.

[0052] The placement block 111 can also be configured in a box shape for storing blood collection bags, blood collection tubes, centrifuges, blood typing test kits, and the like.

[0053] Among the optional methods of this embodiment, the more preferred ones are:

[0054] The extending mechanism 200 further includes a straight cylinder 230 . The straight cylinder 230 is connected to the outer wall of the operating cover 120 , and an output end of the straight cylinder 230 is connected to the side plate 210 .

[0055] When the straight cylinder 230 is extended, it can push the side plate 210 to move, so that the side plate 210 moves away from the operating cover 120, providing enough space for the placement of the arm.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] The placement cover 110 is connected to an arc-shaped cylinder 220 , and the arc-shaped cylinder 220 is communicated with the straight cylinder 230 through a pipeline.

[0058] After the placement cover 110 is opened ninety degrees, the output end of the arc cylinder 220 contacts the operating cover 120. As the placement cover 110 continues to open, the arc cylinder 220 begins to shorten, so that the air in the arc cylinder 220 is conducted to the straight cylinder 230, causing the straight cylinder 230 to extend and push the side plate 210 out.

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] A backing plate 240 is hinged on the operation cover 120 . The backing plate 240 is composed of a plurality of rectangular plates hinged at the first end. The rectangular plates at both ends are hinged to the operation cover 120 and the side plate 210 , respectively.

[0061] When the side plate 210 is away from the operation cover 120 , the side plate 210 pulls the pad 240 to unfold, changing from an “M” shape to an “I” shape, thereby providing padding for the lower part of the arm.

[0062] Among the optional methods of this embodiment, the more preferred ones are:

[0063] The backing plate 240 is connected to an air bag 250 , and a second air pipe 231 is connected between the air bag 250 and the straight cylinder 230 .

[0064] A piston is provided on the rod of the straight cylinder 230. When the piston slides to push out the side plate 210, the air in the straight cylinder 230 is pushed into the airbag 250 through the second air pipe 231, so that the airbag 250 expands, thereby increasing the comfort of the arm support.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
