The storage reel 110 and the recovery reel 120 can be replaced quickly by a concave-convex insertion structure, but the storage reel 110 and the recovery reel 120 can be detached conveniently and can be thrown out during rotation, so that the storage reel 110 and the recovery reel 120 are provided with structures for preventing the throwing-out.

As shown in fig. 6, 9 and 12, for example, the storage reel 110 is mounted at both ends thereof to the two side stands 130 via first axle seats 118. The first shaft base 118 has a first notch portion at an upper portion thereof for allowing the storage reel 110 to enter and exit. Correspondingly, the bottom surface of the front cover 150 is provided with a first stopper 119 corresponding to the first notch portion of the first shaft seat 118, so that the first stopper 119 covers the first notch portion of the first shaft seat 118 when the front cover 150 is in a covered state, and this structure ensures that the storage reel 110 can be taken down by opening the front cover when needing to be replaced, and the notch can be blocked by covering the front cover to prevent the storage reel from being thrown out.

In this embodiment, the front cover 150 may be fixedly connected to the first stop 119 by a screw, and the first shaft seat 118 may be fixedly connected to the stand 130 by a screw or a bolt. The front cover 150 and the first stopper 119 may be integrally molded or bonded.

The front cover of the present embodiment is in the form of a flip cover, so that the first stopper can change its height position according to the flipped state of the front cover. In some embodiments, the rear cover is in the form of a sliding cover, and thus the stopper is fixed differently.

As shown in fig. 9 and 11, both ends of the recovery reel 120 are mounted on the side stands 130 via the second shaft holders 128, and the second shaft holders 128 have second notches at upper portions thereof for the recovery reel to enter and exit. A second stopper 129 corresponding to the second notch portion of the second shaft holder 128 is fixedly coupled to a side of the slide rail 162 facing the recovery reel such that the second stopper 129 covers the second notch portion of the second shaft holder 128 in a state where the slide rail 162 is depressed. In this embodiment, the second stopper is indirectly connected to the slide rail and remains stationary relative to the rear cover 160, so that the recovery reel can be removed by opening the rear cover when it needs to be replaced, and the front cover can block the notch to prevent the recovery reel from being thrown out when it is covered.

The invention also provides a control system of the medical lining towel supply device, so as to realize automatic or manual operation. The control system may include a pressure sensor, a color sensor, a controller, and the like.

The controller is used for controlling the starting and stopping of the first motor based on sensing signals of the pressure sensor and the color sensor. The pressure sensor may act as a trigger signal for the activation of the first drive means. The color sensor can be used as a trigger signal for stopping the first driving device, the controller can adopt a PLC or a single chip microcomputer to control the operation of the whole machine, and the pressure sensor and the color sensor are connected with the controller.

For example, a pressure sensor may be provided in the flexible mat, i.e. underneath the arm of the person to be tested, to detect whether the arm of the person to be tested is placed thereon. The color sensor may be disposed below the first optical axis, and the medical lining cloth may be painted with color blocks or color bands according to a preset length of the lining cloth for a single person.

After the pressure sensor detects that the arm of the person to be tested leaves, the pressure sensor transmits a signal to the controller, and the controller controls the first motor to start to drive the recovery scroll to rotate so as to replace the medical lining towel. When the color sensor detects the next color block, the signal is transmitted to the controller, and the controller controls the first motor to stop rotating.

Because the thickness of the medical lining towel on the scroll can change constantly, the embodiment does not adopt the first motor to control the number of turns of the recovery scroll to realize the replacement of the medical lining towel at a fixed distance, but adopts the color block which is preset by the color sensor and the medical lining towel, and the mode has high control precision, reasonable length of the medical lining towel for one person and avoids cross infection and waste.

In another embodiment, the first motor of the invention can adopt a high-precision control motor, and because the specification design of the storage scroll and the recovery scroll has certain parameters, experiments can also be made in advance, the nth medical liner towel corresponds to the motor angular displacement with preset turns, and the motor rotation is controlled by the controller, so that the lengths of all the medical liner towels are accurately kept consistent.

In some embodiments, the device may be configured in a manual control mode, for example, the medical liner supply further comprises a button for manual control, in which one button controls single-person replacement of a medical liner.

The controller may count the number of times of sensing signals based on the pressure sensor or the color sensor to calculate the used number of the medical supplies and calculate the remaining number of the medical supplies based on the total number of the supplies. The device may also be provided with a display for displaying the total number of copies of the medical drape, the number of used copies, the number of remaining copies, etc. Wherein, button and display can set up the front end at the complete machine, the low level end of blood sampling platform promptly to make things convenient for medical personnel to observe.

In addition, the medical lining towel supply device can also be matched with a device for manually or automatically replacing the tourniquet to simultaneously replace the lining towel and the tourniquet, thereby reducing the operation process of medical staff, executing the standard of one towel with one belt and preventing cross infection.

As shown in fig. 2, in some embodiments, the tourniquet conveyor may include a band-binding station 210, a band cassette 220 for receiving the tourniquet, a band-carrying mechanism, and the like.

The clamping mechanism 240 is installed on the conveyor belt 231, the tourniquet belt is clamped from the first position of the first side end of the binding table 210 and is conveyed to the second position of the second side end through the conveyor belt 231, the tourniquet belt can be unfolded, and after the arm of the person to be tested is placed above the binding table 210, the medical personnel can carry out binding by pulling down the tourniquet belt, so that the subsequent blood sampling operation process can be carried out. The tourniquet conveying device can lead out the tourniquet from the belt box, does not need medical staff to arrange manually, reduces the labor intensity of the medical staff, and can adopt the disposable tourniquet in the belt box to avoid cross infection.

The first position and the second position of the embodiment of the invention depend on the length of the belt tying table for unfolding the pulse pressing belt, and when the length of the upper table surface is longer, the first position and the second position can be arranged at two sides of the upper table surface of the belt tying table; when the length of the upper table surface is not enough to the length of the tourniquet belt of a single person, the first position and the second position can be arranged at two side ends of the belt tying table. The first position may be considered as an initial position of the belt conveying mechanism and the second position may be considered as an end position of the belt conveying mechanism. The belt clamping mechanism of the belt conveying mechanism clamps the head end of the vein pressing belt from the first position and starts conveying the vein pressing belt, and the head end of the vein pressing belt is loosened from the second position. After the blood sampling of a person to be tested is completed, the belt conveying mechanism returns to the first position, and the pulse pressing belt is clamped by the clamping mechanism and then the steps are repeated.

Fig. 13 is a schematic view showing the structure of the rear plate of the band stand 210 removed to show the inner structure thereof. Fig. 14 is a partially enlarged view of a portion a in fig. 13. Fig. 15 is a schematic plan view of the belt conveying mechanism, and the arrangement shape of the conveying belt and the half section of the entrainment mechanism can be visually seen. Fig. 16 is a partially enlarged schematic view of a portion C in fig. 15. Fig. 17 to 19 are schematic perspective views of the connecting block, the magnetic clamping jaw and the movable clamping jaw respectively.

In some embodiments, the entrainment mechanism may be a magnetic attraction type mechanism or a negative pressure air suction type mechanism. Taking the magnetic-type structure as an example, as shown in fig. 14 and 16, the entrainment mechanism 240 may include a connection block 241, a magnetic jaw 242, a movable jaw 243, and the like. Wherein the connecting block 241 is mainly used for mounting the entire entrainment mechanism on the conveyor belt 231. The magnetic clamping jaw 242 and the movable clamping jaw 243 are mainly used for mutually matching and clamping or releasing the tourniquet. The conveyor belt 231 is mainly used to draw out and spread the tourniquet belt.

In this embodiment, as shown in fig. 16 and 17, one end of the bottom surface of the connecting block 241 has a protrusion 2411, and the protrusion 2411 is fixedly connected to the conveyor belt, and the connection may be by adhesion. The connecting block 241 is generally long, and the main body structure thereof can be used as a sliding rod 2412 for keeping relatively fixed, a groove 2413 is arranged at one end of the top surface of the connecting block 241, which is opposite to the convex part 2411, and two end parts of the groove 2413 are arc surfaces.

As shown in fig. 16 and 18, magnetic jaw 242 may include a slotted slide mount 2421 and a second jaw 2423 extending and projecting diagonally upward from slotted slide mount 2421. One end of the sliding groove seat 2421 corresponding to the second clamping jaw 2423 is used as a first clamping jaw (hereinafter, the reference numeral of the first clamping jaw is referred to as 2421), and the sliding groove seat 2421 is provided with a through groove 2422 for sleeving the connecting block 241, so that the magnetic clamping jaw 242 can slide relative to the connecting block 241. Furthermore, the magnetic jaw 242 is provided with a pivot hole 2424 for connecting with the movable jaw 243, and is further provided with a slot 2425 corresponding to the groove 2413 of the connecting block, so that the movable jaw 243 can extend into. The first jaw 2421 and the second jaw 2423 of the magnetic jaw 242 may be made of a magnetic material, such as a permanent magnetic ferromagnetic material, or may be provided with corresponding ferromagnetic members at the positions thereof.

As shown in fig. 16 and 19, the movable jaw 243 is made of a material that can be attracted to the first jaw 2421 and the second jaw 2423 of the magnetic jaw. The movable clamping jaw 243 is also pivotally connected to the magnetic clamping jaw 242, one end of the movable clamping jaw has a bending portion 2431 extending into the groove 2413 of the connecting block, and the other end 2432 of the movable clamping jaw can be attracted to the first clamping jaw 2421 and the second clamping jaw 2423 of the magnetic clamping jaw. The movable jaw 243 is disposed between the first jaw 2421 and the second jaw 2423 of the magnetic jaws and is engaged with one of the jaws. The movable jaw 243 is pivotally connected to the magnetic jaw 242 by its pivot holes 2433. The end of the bending part 2431 of the movable clamping jaw is correspondingly of a cambered surface structure.

When the magnetic clamping jaw 242 and the connecting block 241 slide relatively, the movable clamping jaw 243 can slide together with the magnetic clamping jaw 242 relative to the connecting block 241, and the bent part 2431 of the movable clamping jaw is in contact with one end of the connecting block groove 2413, so that the movable clamping jaw 243 rotates around a pivot and is released from the clamping jaw which is engaged with the movable clamping jaw before and is engaged with the other clamping jaw to clamp or release the tourniquet.

In the above embodiment, referring to fig. 16, it can be seen that when the conveyor belt stops rotating, the connecting block 241 is also kept fixed, and the magnetic clamping jaw 242 and the movable clamping jaw 243 can continuously slide a short distance due to inertia. For example, as the magnetic jaw 242 and the movable jaw 243 slide relatively downward in FIG. 16, the movable jaw 243 may change from engagement with the second jaw 2423 to engagement with the first jaw 2421.

For example, when the movable clamping jaw 243 is attracted to the first clamping jaw 2421 of the magnetic clamping jaw, the tourniquet can be clamped; when the movable clamping jaw 243 is attracted with the second clamping jaw 2423 of the magnetic clamping jaw, the tourniquet can be released. With reference to the drawings, it can be seen that when the magnetic jaw 242 and the movable jaw 243 slide relative to each other on the connecting block towards the connecting portion 241 protruding from the connecting block, the movable jaw 243 is shifted to be engaged with the first jaw 2421, and vice versa, the movable jaw 2423 is engaged.

The clamping mechanism of the embodiment of the invention creatively provides a connecting block and a magnetic clamping jaw which slide relatively, and a movable clamping jaw which can change the attraction state, and clamps or releases the tourniquet through the sliding direction.

The belt box of the embodiment of the invention can be provided with the whole vein pressing belt, and each vein pressing belt of a single person is connected in a point-breaking manner and can be easily broken by medical personnel.

The whole vein pressing belt of the belt box of the embodiment of the invention can also be cut off by a cutter. For example, the tourniquet delivery apparatus according to the embodiment of the present invention may further include an electromagnetic cutting mechanism provided on a side of the band-tying station 210 and configured to partially cut off the tourniquet. The electromagnetic shut off mechanism may include a push-pull electromagnet 251, an extension arm 252 to which the plunger of the push-pull electromagnet is attached, a cutting blade 253 secured at the end of the extension arm 252, and a hard pad 254 secured to the tie table.

Fig. 20 is a schematic perspective view of the electromagnetic cutting mechanism and the related parts of the entrainment mechanism, and fig. 21 is a schematic sectional view of the extension arm 252, the cutting blade 253 and the hard shim 254 of the electromagnetic cutting mechanism.

As shown in fig. 20, the push-pull electromagnet 251 may be disposed within the band table, with an extension arm 252 extending from the inside to the outside of the belt, the extension arm 252 having at least one end 2521 extending outside the belt 231, the end 2521 being pushed and pulled in a direction perpendicular to the end face of the belt; preferably, two are provided symmetrically. The cutting blade 254 is arranged in the width direction of the conveyor belt to transversely cut off the partial tourniquet.

The hard pad 253 is disposed outside the conveyor belt 231 and inside the end 2521 of the extension arm to interpose the tourniquet between the hard pad 253 and the end 2521 of the extension arm.

In the embodiment, the electromagnetic cutting mechanism is adopted to cut off only the wide edge part of the tourniquet belt, so that the tourniquet belt can be torn off conveniently by medical personnel without opening a point-break notch on the tourniquet belt in advance.

As shown in fig. 21, since the tourniquet is made of highly elastic rubber, and cannot be easily cut by the cutting tool, in the embodiment of the present invention, the hard pad 253 has a downwardly concave slit at a position corresponding to the cutting blade 254, so that the cutting blade 254 can extend into and cut the tourniquet.

In addition, the end 2521 of the extension arm 252 is also provided with a cushion for compressing the tourniquet, including a first cushion 255A disposed above the cutting blade 254 and a second cushion 255B disposed below the cutting blade 254. Both cushions may be bonded to the inside of the end 2521 of the extension arm in a position that avoids the position of the cutting blade 254. Two cushions are provided at the boundary of the cutting blade 254, which can press the two sides of the tourniquet when the blade cuts the tourniquet, so as to prevent the tourniquet from entering the concave slot of the hard pad 253. The second function is to limit the cutting blade, and the second soft pad 255B at the lower end of the cutting blade can press the starting end of the next pulse pressing belt for a single person.

In some embodiments, as shown in fig. 22, a concave portion 2531 is provided at an intermediate position of the upper end of the hard pad 253 for blocking the connecting block 241 of the entrainment mechanism, so that when the conveying belt drives the connecting block 241 to return to the first position, the magnetic jaw 242 and the connecting block 241 slide relatively, and the movable jaw 243 attracts the first jaw to clamp the tourniquet belt.

The hard pad 253 may be further provided with bent connection portions 2532 at both sides thereof to be fixed to both side walls of the band table by screws. The bottom end of the hard pad 253 may be further provided with a bevel transition 2533 to facilitate the tourniquet to be guided onto the hard pad 253 from the bottom up.

In some embodiments, the positional relationship of the second cushion 255B, the recess 2531 of the hard spacer, and the connection block 241 of the entrainment mechanism is such that: under the state that the connecting block 241 of the entrainment mechanism is blocked by the concave part 2531 of the hard gasket, the first clamping jaw 2421 of the magnetic clamping jaw is attracted with the movable clamping jaw 243, the second soft cushion 255B horizontally corresponds to the attraction position thereof, or the second soft cushion 255B is higher than the attraction position thereof. This arrangement ensures that even when the entrainment mechanism returns for air ride, the start of the next single tourniquet compressed by the second cushion 255B can be found at the first position,

generally, the soft cushion applies a certain pressure to the tourniquet to prevent the tourniquet from falling.

In some embodiments, the tape cassette 220 may be disposed at a bottom of the band stand 210, and the outlet 221 of the tape cassette 220 is disposed at a bottom of the first side end of the band stand 210. But is not limited thereto, the tape cassette 220 may be provided at one side of the band stand 210.

In some embodiments, at least one guide shaft 222 is further provided at the cassette outlet 221, and is fixed to the band-binding station 210 for guiding the tourniquet. The tourniquet of the embodiment of the invention can be a flat-sheet type strip structure, and the guide shaft 222 can avoid the winding phenomenon after the tourniquet is folded.

In some embodiments, the second drive means may comprise a second motor and a drive pulley 232 connected to an output shaft of the second motor. The conveying belt 231 may be a timing belt, the driving pulley 232 and the driven pulley may be timing pulleys, and the guide pulley outside the conveying belt 231 may be a pulley without a tooth shape.
