[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] The present invention provides an auxiliary device for blood sample sampling of multiple myeloma patients based on LDH-induced chemotherapy, including a base 1;
[0037] At both ends of the top of the base 1, there are provided pressing mechanisms 2 for arm fixation. At one end of the top of the base 1, there is provided a venous occlusion mechanism 3 for arm puncture. Above the base 1, there is provided a syringe pressing mechanism 4 for limiting the blood sampling syringe. Inside the base 1, there is provided a positioning mechanism 5 for limiting the test tube;
[0038] The pressing mechanism 2 includes a support component, a power component, a pressing-down component, and a sliding component. The support component is arranged on the top of the base 1. The power component is arranged outside the support component. The pressing-down component is arranged inside the support component. The sliding component is arranged outside the pressing-down component;
[0039] Through the cooperation among the support component, the power component, the pressing-down component, and the sliding component, the upper arm position and the lower arm position in the patient's arm can be simultaneously pressed to avoid the inability to perform puncture blood sample sampling operations due to resistance.
[0040] The syringe pressing mechanism 4 includes a connection component, an elastic component, and a micro-pressing component. The connection component is arranged on the top of the base 1. The elastic component is arranged at the bottom of the connection component. The micro-pressing component is arranged at the bottom end of the elastic component;
[0041] Through the cooperation among the connecting component, the elastic component and the micro-pressure component, the blood pressure measurement operation on the patient's arm can be realized, which is not only beneficial to the blood collection operation, but also can press and hold the position of the needle handle for blood collection and limit the pressure on the tail end pipeline, so as to avoid blood collection interruption caused by deviation after puncture and avoid the secondary puncture operation.
[0042] The patient's arm is fixed by the pressing mechanism 2, the patient's arm is assisted in blood collection by the blood pressure measurement mechanism 3, and the sampling needle tube is pressed and limited according to the pressing tube mechanism 4, and the extracted blood is discharged into the test tube in the positioning mechanism 5 in a directional manner.
[0043] Preferably;
[0044] As Figure 2 As shown in the figure, the support component includes a support plate 21, the support plates 21 are respectively fixedly installed at both ends of the top of the base 1, a connection box 22 is fixedly installed on the top of the support plate 21, and through holes 210 are opened at the centers of the top and bottom of the connection box 22, which plays a supporting role, can assist in limiting the internal components, and can also prevent the internal components from being blocked during operation.
[0045] As Figure 2 As shown in the figure, the power component includes a motor 23, the motor 23 is fixedly installed on the outside of the connection box 22, the output shaft of the motor 23 is key-connected with a transmission shaft 24, a gear 25 is fixedly installed on the outside of the transmission shaft 24, and a sleeve 211 is rotatably connected through the inside of both connection boxes 22. The sleeve 211 is located outside the transmission shaft 24. By changing the rotational force into a downward pressure according to the power output operation, the patient's arm is pressed and held, so that it can be fixed on the auxiliary device, which is beneficial to the subsequent blood collection, that is, the blood sample sampling work.
[0046] As Figure 2 As shown in the figure, the downward pressing component includes a toothed plate 26, the toothed plate 26 meshes on one side of the gear 25, a connection frame 27 is fixedly installed on the outside of the toothed plate 26, a pressing seat 28 is fixedly installed at the bottom of the connection frame 27, and a first rubber pad 29 is fixedly installed at the bottom of the pressing seat 28. By using the meshing transmission method and changing the rotational force into a downward pressure as described above, the patient's arm pressing operation is completed. At the same time, the arc-shaped pressing seat 28 and the first rubber pad 29 can better adapt to the patient's arm and the pressing operation, and the setting of the first rubber pad 29 can protect the patient's arm during the pressing process.
[0047] As Figure 2 As shown in the figure, the sliding component includes a chute 212, the chute 212 is opened on the inner side wall of the support plate 21, a slider 213 is slidably connected inside the chute 212, and the inner side of the slider 213 is fixed to the outside of the pressing seat 28. According to the sliding connection relationship, while limiting the pressing seat 28, it can also ensure the verticality and stability of its up and down movement.
[0048] When blood sample collection is required from the arm of a myeloma patient, the patient needs to first pass the arm through the bracket 33 and the blood pressure cuff 34 and place the arm on the inner wall of the second rubber pad 32. At this time, the arm lies horizontally on the inner wall of the second rubber pad 32 in a transverse direction. Then, the patient's arm moves horizontally as required and is adjusted to the desired position. At this time, the motor 23 is started, and the motor 23 directly drives the gear 25 to rotate through the transmission shaft 24. At this time, the rotation direction of the gear 25 is counterclockwise. By means of meshing connection, the two sets of toothed plates 26 and the connecting frame 27 are directly driven to move downward together. At this time, the pressing seat 28 and the first rubber pad 29 are pushed to move downward simultaneously until the first rubber pad 29 contacts the patient's arm and the pressing operation is achieved. The pressing force can be controlled according to the actual situation. Based on the fact that both the pressing seat 28 and the first rubber pad 29 are arc-shaped and the first rubber pad 29 is made of rubber, it can better adapt to the patient's arm and protect the pressed part;
[0049] Based on the above, when the two sets of pressing seats 28 move downward simultaneously, they will drive the slider 213 to move downward. At this time, the slider 213 will also slide inside the chute 212 to ensure the stability of the simultaneous downward movement of the two sets of pressing seats 28. And the two sets of pressing seats 28 and the first rubber pad 29 can respectively limit and press the position of the upper arm and the lower arm in the patient's arm, leaving the inner position of the elbow joint for puncture blood sample sampling operation.
[0050] Furthermore;
[0051] As Figure 5 shown, the connecting component includes a fixed frame 41. The fixed frame 41 is fixedly installed on the top of the base 1. The outside of the fixed frame 41 is slidably connected with an installation frame 42. The bottom of the outside of the installation frame 42 is threadedly penetrated by a bolt 43, which can realize the support operation and can also adjust the pressed position as required to meet the needs of people during actual operation.
[0052] As Figure 5 shown, the elastic component includes a first spring 44. The first spring 44 is welded to the top inside the installation frame 42. The top of the installation frame 42 is slidably connected in a penetrating manner with a pull rod 45. A limit block 46 is fixedly installed on the outside of the pull rod 45. A limit hole 49 is opened at the top of the installation frame 42. The first spring 44 is located outside the pull rod 45, which is convenient for pressing the handle position of the puncture needle and the tail end pipeline in a way of elastic downward push, so as to avoid partial puncture at the puncture position and the needle tip offset caused by the pipeline movement driving the needle head to shift, resulting in a change in the puncture position.
[0053] As Figure 5As shown in the figure, the micro-pressure assembly includes a first pressing plate 47 and a second pressing plate 48. The first pressing plate 47 is welded to the bottom of the first spring 44 on one side, and the second pressing plate 48 is welded to the bottom of the first spring 44 on the other side. The first pressing plate 47 and the second pressing plate 48 are rotatably connected to the pull rod 45, and can respectively limit and press the needle handle and the pipeline. An arc-shaped groove is opened at the bottom of the second pressing plate 48, and the opening of the arc-shaped groove is mainly used to adapt to the pipeline to prevent the blood collection tube from being flattened and causing blood to not enter the inside of the negative pressure test tube.
[0054] When taking a blood sample, first wipe and clean the wrist. You can use a disinfected alcohol cotton for wiping and cleaning, including but not limited to the above cleaning method. At this time, take out the syringe and puncture the position of the arm vein. After the puncture is completed, rotate the needle handle to fit on the surface of the arm, and then pull up the pull rod 45. The pull rod 45 drives the limit block 46 to move upward at the same time. At the same time, rotating the pull rod 45 will drive the limit block 46 to rotate together until the limit block 46 is symmetrically arranged with the top of the limit hole 49. Then slowly release the pulling force. According to the elastic push of the first spring 44, the first pressing plate 47 is pressed on the needle handle position, and the second pressing plate 48 can be pressed on the outside of the pipeline connected to the tail end of the needle head, so as to realize limit pressing and wait for subsequent sampling operations.
[0055] In addition, the distance between the two can be adjusted as required. For example, rotate the bolt 43 counterclockwise. At this time, the bolt 43 releases the pressing state on the fixing frame 41. Then directly push and pull the mounting frame 42, and the mounting frame 42 can slide on the outside of the fixing frame 41 until it slides to the required position. When in the preset position, rotate the bolt 43 clockwise, and use the bolt 43 to press against the fixing frame 41 to complete the locking work. The other group is adjusted for position change in the same way as above, so as to improve the adaptability during actual use.
[0056] The stability during blood sample collection from myeloma patients is improved. It can not only prevent the needle from failing to penetrate into the designated position, but also prevent the needle from falling off and being mis-pierced during the sampling process.
[0057] Furthermore;
[0058] Such as Figure 3 As shown in the figure, the blood pressure pressing mechanism 3 includes a support base 31. The support base 31 is fixedly installed on the top of the base 1. A second rubber pad 32 is fixedly installed on the top of the support base 31. One end of the top of the base 1 is also fixedly installed with a bracket 33. A blood pressure pressing airbag 34 is installed on the inner side wall of the bracket 33. The top of the blood pressure pressing airbag 34 is communicated with a connecting pipe 35. One end of the connecting pipe 35 is communicated with a hose 36, which is beneficial to support the arm of the myeloma patient and at the same time complete the blood pressure pressing operation on the patient's arm in the way of a blood pressure pressing belt, so as to facilitate subsequent blood collection operations.
[0059] Based on the above, at this time, the arm passes through the blood pressure cuff 34. First, the blood pressure cuff 34 is connected to an external air pump through a connecting pipe 35 and a flexible hose 36. Since the air pump is a mature existing technology, there is no need to describe it in detail in the specification. When blood pressure measurement is required, the air pump operates, and inflates the inside of the blood pressure cuff 34 through the flexible hose 36 and the connecting pipe 35, causing the blood pressure cuff 34 to expand and perform blood pressure measurement on the patient's arm. At the same time, there are two groups of pipe valves provided on the connecting pipe 35. The position close to the flexible hose 36 is an intake check valve, which can be directly opened when intake is required as described above. When exhaust is required, the other group of exhaust check valves can be directly opened, causing the gas to be discharged outward, so that the gas inside the blood pressure cuff 34 is emptied, facilitating the placement and removal of the arm. The exhaust check valve is in a closed state when inflating and expanding;
[0060] Wiping disinfection and puncture work can only be carried out after blood pressure measurement to ensure stable and efficient blood sample sampling operations for myeloma patients.
[0061] It realizes blood pressure measurement of the arm and pressure holding and limiting of the needle pipeline during blood sample sampling of myeloma patients, not only realizes stable blood sample extraction, but also can limit the sampling tube and the needle, without the need for medical staff to continuously press the position of the needle handle by hand.
[0062] Finally;
[0063] As Figure 4 and 7 shown, the positioning mechanism 5 includes a second spring 51 and a telescopic rod 52. The second spring 51 and the telescopic rod 52 are both fixedly installed on the inner side wall of the base 1. The second spring 51 is arranged outside the telescopic rod 52. One ends of the second spring 51 and the telescopic rod 52 are both fixedly installed with a positioning frame 53. An adaptation hole 56 is opened on one side of the base 1. The positioning frame 53 slides in the adaptation hole 56. A lengthening plate 55 is fixedly installed at the bottom on one side of the base 1. A loading rack 54 is placed on the top of the lengthening plate 55. The loading rack 54 is located inside the positioning frame 53, and can clamp and fix a test tube rack carrying test tubes, avoiding test tube breakage and blood sample outflow caused by test tube dropping during the puncture process, and improving the safety and protection during the blood sample sampling process.
[0064] When the preparation work is in progress, take out the test tube rack carrying the test tubes, and then pull the positioning frame 53. Both ends of the positioning frame 53 are fixedly installed with connecting blocks, which is conducive to pulling the positioning frame 53. When pulling the positioning frame 53, the positioning frame 53 will slide inside the fitting hole 56, and is located on the top of the extension plate 55 and is in a fitting state with the top of the extension plate 55. During the pulling process, the second spring 51 and the telescopic rod 52 will be stretched until the test tube rack, that is, the loading rack 54 marked and presented in the figure, can be placed. Place the loading rack 54 on the top of the extension plate 55 and inside the positioning frame 53, and then slowly release the pulling force until the loading rack 54 is clamped between the positioning frame 53 and the base 1 according to the elastic pulling principle.
[0065] It realizes the advantages of limiting and supporting the placement of the test tube parts, and avoids falling caused by unconscious touching during operation.
