Description

Technical Field

[0001] The utility model relates to an auxiliary device, in particular to a medical clinical blood sampling auxiliary device. Background Art

[0002] Venous blood sampling is an important clinical procedure, requiring the insertion of a needle into a patient's vein. Currently, after blood collection, patients are required to apply pressure to the blood collection site. This pressure shrinks or closes the rupture in the blood vessel, slowing blood flow and allowing platelets, fibrin, and red blood cells to rapidly form a thrombus, ultimately achieving hemostasis.

[0003] At present, the traditional compression method is generally that medical staff places medical cotton balls or medical cotton swabs on the blood collection site of the blood donor's arm, and then the blood donor manually presses the blood collection site. This method requires the blood donor to continue manual pressing. When the blood donor goes to the hospital alone to have blood drawn, it is inconvenient to transfer personal belongings on the way to the next examination item, and it is not conducive to answering and making phone calls. At the same time, the medical cotton balls or medical cotton swabs are easily contaminated by bacteria in the ambient air when exposed to the air for a long time, so there is a risk of bacterial infection in the wound on the blood donor's arm.

This arrangement can drive the guide component and the retractable fixing component to operate simultaneously through the driving component 2. At the same time, under the guiding effect of the guide component on the retractable fixing component, the fixing tape adhesive layer 17 in the retractable fixing component can be surrounded and adhered to the wound on the arm of the blood collector where a cotton swab (alcohol cotton, etc.) is placed to assist in short-term pressing of the blood collection site after blood collection. In general, compared with previous blood collection auxiliary devices, this device can provide blood collection assistance to the blood collector. The auxiliary short-term pressing of the blood collection site on the arm is beneficial for the blood donor to temporarily free his hands when he needs to do so just after completing the blood collection (such as when he is going to the next examination item to transfer his belongings (that is, transfer his belongings from the non-blood collection arm side to the blood collection arm side) or answering a phone call, etc. At the same time, the pressing end of the cotton swab (alcohol cotton, etc.) is always located in the fixing belt adhesive layer 17 during the process of the blood donor transferring his belongings (that is, transfering his belongings from the non-blood collection arm side to the blood collection arm side) or answering a phone call, which is beneficial for isolating external bacteria and reducing bacterial infection at the wound on the blood donor's arm. Possibility, more practical; the driving assembly 2 includes a motor 5 fixedly arranged on the inner wall of the rear side of the shell 1, the front side of the motor 5 is connected to the first rotating shaft 6, and the second rotating shaft 7 is correspondingly arranged below the first rotating shaft 6. The rear end of the second rotating shaft 7 is arranged on the inner wall of the rear side of the shell 1 through a fixed rotating connecting member 8. Two first gears 9 are arranged at intervals on the periphery of the first rotating shaft 6, and two second gears 10 are arranged on the periphery of the second rotating shaft 7 corresponding to the two first gears 9. The two first gears 9 are externally meshed with the two second gears 10. The motor 5 can adopt the integrated DC brushless servo motor 5 of PRMotor RGM5730PGH.

The whole process is simple in principle and easy to operate. By using a motor 5 as the main drive, the synchronous transmission between the first gear 9 and the second gear 10 can be achieved, which is more economical and makes the entire transmission process smoother and more efficient. At the same time, it also increases the service life of the entire device to a certain extent.The guide assembly 3 includes a guide shell 11 arranged in the shell 1, and a first guide groove 12 is respectively provided on the inner wall of the front and rear sides of the guide shell 11, and a chain 13 is movably provided in the two first guide grooves 12. The two chains 13 are respectively meshed with the corresponding first gear 9. The inner sides of the two chains 13 are respectively connected to one end of a guide block 14. The guide shell 11 inside the two first guide grooves 12 is provided with two second guide grooves 15 corresponding to the front and rear ends of the guide block 14. Under the action of the two chains 13 meshing with the corresponding first gear 9, the two chains 13 are synchronously moved in the corresponding first guide grooves 12 in a clockwise (relative to the front side of the entire device) circumferential direction. As the two chains 13 move circumferentially, the position of the guide block 14 on them also changes circumferentially in a clockwise (relative to the front side of the entire device) along the second guide groove 15, thereby driving the fixed belt rubber layer 17 to move circumferentially in a clockwise (relative to the front side of the entire device) . The principle is simple and easy to use. The invention can realize the above-mentioned function, and it is more economical, and the transmission between the first gear 9 and the chain 13 makes the whole movement process smoother; the retractable and fixed component includes a fixed belt roll 16, which is located between the two first gears 9 and its inner end face is wound around the periphery of the first rotating shaft 6, and the fixed belt roll 16 includes a fixed belt adhesive layer 17 and a release paper layer 18, wherein the starting end of the fixed belt adhesive layer 17 is bonded to the periphery of the guide block 14, and the starting end of the release paper layer 18 is wound around the periphery of the second rotating shaft 7 to form a release paper layer roll 19, which can be Driven by the drive assembly 2, the adhesive layer 17 of the fixing tape separates from the release paper layer 18. Simultaneously, the adhesive layer 17 moves along with the guide block 14, and the release paper layer 18 simultaneously wraps around the release paper roll 19. This allows for rapid separation of the adhesive layer 17 from the release paper layer 18, facilitating ready access to the adhesive layer 17 and ensuring its adhesion. This allows for better short-term assistance (e.g., when transferring belongings or making phone calls while on the way to the next inspection item).

[0042] like Figure 1 、 Figure 2 and Figure 4 As shown, it also includes a power control component 20, which includes a battery 21 arranged on the inner wall of the bottom of the shell 1, a controller 22 arranged above the battery 21, and a keypad 23 arranged on the front side of the shell 1. The keypad 23 and the motor 5 are electrically connected to the controller 22 and the battery 21 respectively. The controller 22 can adopt a small controller PNOZmulti 2 model controller 22. This controller 22 can be applicable to commonly used communication networks and can also connect, control and monitor multiple components at the same time. This setting is powered by the battery 21 and controls the keypad 23 and the motor 5 respectively through the controller 22, so that the device can operate normally.

[0043] like Figure 1and Figure 5 As shown, it also includes a support rod 24 (multiple support rods 24 can be provided), the first rotating shaft 6 rotates and passes through the first supporting tube 25 provided on the support rod 24, and the second rotating shaft 7 rotates and passes through the second supporting tube 26 provided on the support rod 24, which can provide auxiliary support for the first rotating shaft 6 and the second rotating shaft 7 while allowing the first rotating shaft 6 and the second rotating shaft 7 to rotate normally.

[0044] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it also includes an arc-shaped support plate 27. The arc-shaped support plate 27 is integrally formed with the shell 1 and is located on the inner side of the guide shell 11. The arc-shaped support plate 27 and the upper half of the inner end surface of the guide shell 11 together form an arm through-hole. A flexible pad can be provided on the arc-shaped support plate 27 to improve the comfort of the blood collector's arm during the blood collection process. This setting facilitates the placement of the blood collector's arm and can limit the position of the blood collector's arm, providing convenience for subsequent disinfection, blood collection and other processes of medical staff.

[0045] like Figure 2 and Figure 9 As shown, the front side of the shell 1 corresponds to the guide shell 11 and has two openings 29 symmetrically opened in the upper and lower parts, which facilitates the medical staff to cut the fixing tape adhesive layer 17 and pull the cut end of the fixing tape adhesive layer 17. At the same time, the fixing tape adhesive layer 17 can be quickly adhered to the blood collection position of the blood collector's arm after the blood collector completes blood collection, which is beneficial for the medical staff to quickly surround and adhere the fixing tape adhesive layer 17 to the blood collection position of the blood collector after completing blood collection.

[0046] like Figure 1 As shown, a guide slot 28 is provided at the bottom of the right side of the guide shell 11, and the top of the first gear 9 is placed in the guide slot 28 and is meshed with the outer ring of the chain 13, which is conducive to the first gear 9 driving the chain 13 to move, thereby enabling the guide block 14 to drive the fixed belt rubber layer 17 to move synchronously, which is conducive to quickly realizing the circumferential movement of the fixed belt rubber layer 17.

[0047] like Figure 1 and Figure 7As shown, a limit support plate 30 is formed horizontally and integrally on the guide housing 11 above the guide slot 28. The limit support plate 30 is located in the gap between the front and rear chains 13. A limit guide hole 31 is provided on the limit support plate 30 corresponding to the fixed belt roll 16. The starting end of the fixed belt adhesive layer 17 is passed through the limit guide hole 31 from bottom to top and bonded to the guide block 14. A Teflon coating is provided at the limit guide hole 31. The Teflon coating (generally prepared by electrostatic spraying) is very smooth and has extremely low surface energy, thus achieving hydrophobic, oleophobic and non-stick properties. The effect of this arrangement is that on the one hand, this arrangement can play a guiding and supporting role in the process of the guide block 14 driving the fixed belt adhesive layer 17 to move. On the other hand, this arrangement can leave a small section of the fixed belt adhesive layer 17 at one end of the fixed belt roll 16 on the limiting support plate 30 when the guide block 14 drives the fixed belt adhesive layer 17 to make a circle and is cut off. When the cutting is completed, the guide block 14 moves to the limiting support plate 30 again and can be bonded to the fixed belt adhesive layer 17 on the limiting support plate 30 again. The principle is simple and the operation is easy. In this way, short-term auxiliary pressing of multiple blood collectors can be achieved by reciprocating.

[0048] like Figure 4 、 Figure 6 、 Figure 9 and Figure 10 As shown, the inner end of the first guide groove 12 is connected to the outer end of the second guide groove 15 , which is conducive to achieving synchronous movement of the chain 13 and the guide block 14 .

[0049] like Figure 1 、 Figure 4 and Figure 9 As shown, the middle part of the inner end surface of the guide shell 11 is provided with a circumferential opening 29, which makes it convenient for medical staff to cut the fixing tape adhesive layer 17 and pull it to the right so that it is pulled out from the circumferential opening 29 to surround and bond the blood collection site on the blood donor's arm.

[0050] like Figure 6 、 Figure 9 and Figure 10 As shown, the guide blocks 14 are symmetrical in front and back and are both arranged in a stepped columnar shape, and the diameter of the middle part is larger than the diameter of the front and rear end parts. This arrangement allows both ends of the guide block 14 to be well guided and limited by the corresponding second guide grooves 15. At the same time, during the process of the guide block 14 guiding the fixed tape adhesive layer 17, the fixed tape adhesive layer 17 is always spaced apart from the chain 13, preventing the fixed tape adhesive layer 17 from adhering to the chain 13 during the guiding process and affecting subsequent shearing steps.

[0051] The specific operating principle is:

[0052] When using this blood collection auxiliary device, it is first necessary to power the device through a battery or an external power supply, so that the electrical components contained in the device are in standby or running state, and then the blood collector passes the arm to be blooded through the arm through-hole formed by the arc-shaped support plate and the upper half of the inner end surface of the guide shell, and then places it on the arc-shaped support plate and aligns the blood collection part with the circumferential opening of the inner end surface of the guide shell; after the medical staff completes blood collection for the blood collector, click on the keyboard, and control the motor operation through the controller to drive the first rotating shaft to rotate, and then drive the fixed belt roll and the two first gears on the first rotating shaft to rotate synchronously. On the one hand, under the meshing connection between the two first gears and the corresponding chains, the two chains are synchronously moved clockwise (relative to the front side of the entire device) in the corresponding first guide groove in a circumferential direction. As the two chains move circumferentially, the position of the guide block on them (the initial position of the guide block is as shown in FIG. 1 ) is changed. Figure 1 The second guide groove is rotated in a clockwise direction (relative to the front side of the whole device) and the guide block drives the fixing tape adhesive layer to expand in a clockwise direction (relative to the front side of the whole device). When the guide block slides past the upper opening position in the second guide groove, the fixing tape adhesive layer can already surround the arm of the blood donor. At this time, the medical staff can use a shearing tool (scissors, etc.) to cut the fixing tape adhesive layers corresponding to the two openings at the same time, and then glue the two cut ends of the cut fixing tape adhesive layer together, and then pull the entire cut fixing tape adhesive layer to the right to make it surround and glue it to the wound on the arm of the blood donor where a cotton swab (alcohol cotton, etc.) is placed to assist in short-term pressing of the blood collection position after blood collection, which is beneficial for the blood donor to be able to The second gear is engaged with the second gear and the second gear is engaged with the second gear, so that the second gear drives the second rotating shaft to rotate counterclockwise synchronously, thereby causing the release paper layer to be wound on the release paper layer roll synchronously; during the above-mentioned cutting process, the guide block continues to move clockwise (relative to the front side of the entire device) with the chain. When the medical staff completes the cutting of the fixed tape adhesive layer, since the upper and lower openings are located on the left side of the shell corresponding to the limiting support plate, a small section of the fixed tape adhesive layer at one end of the fixed tape roll is left on the limiting support plate after cutting. When the cutting is completed, the guide block moves to the limiting support plate again and can be bonded with the fixed tape adhesive layer on the limiting support plate again. In this way, short-term auxiliary pressing for multiple blood drawers can be achieved by reciprocating.
