Description

Technical Field

[0001] The invention belongs to the technical field of blood drawing for intravenous treatment, and in particular is a blood drawing sampling device for intravenous treatment nursing and a use method thereof. Background Art

[0002] In the field of intravenous therapy and nursing, blood sampling is an indispensable part of the medical process. Blood testing is a common and effective means to diagnose the cause of a patient's illness. Currently, blood collection and filling in test tubes before blood testing are carried out in stages. Blood is mainly drawn from the patient's vein with a syringe and then pushed into a test tube for testing.

[0003] Traditional blood sampling devices are often simple in design, and patients may need to be pricked with needles multiple times to collect different samples, which increases their pain and discomfort. At the same time, problems such as the risk of cross-contamination between samples during the sampling process, the fixation stability of the sampling needle, and the disinfection effect before sampling also occur from time to time, affecting the accuracy and safety of sampling.

[0004] First, traditional blood sampling devices usually have only one sampling cavity, which cannot meet the needs of collecting two samples at the same time. As a result, when multiple samples need to be collected, patients often need to undergo multiple injections, which not only increases the pain of patients, but also may increase the risk of infection due to multiple operations. In addition, due to the lack of effective spatial separation measures, cross-contamination is prone to occur between different samples, affecting the purity and accuracy of the samples.

[0005] Secondly, in terms of sampling efficiency and patient comfort, traditional blood sampling devices often lack flexible adjustment mechanisms and cannot accurately locate according to the location and depth of the patient's blood vessels, which not only increases the difficulty of operation for medical staff, but may also cause discomfort to patients due to inaccurate positioning. At the same time, the control of clamping force during the sampling process is also very important. Too tight or too loose may affect the patient's comfort and even cause sampling failure.

[0006] Furthermore, in the disinfection process before sampling, traditional methods usually use spraying or wiping to disinfect, but these methods often have problems such as incomplete disinfection, limited coverage, and disinfectant residue. This may not only affect the accuracy of sampling, but also increase the risk of infection for patients. Summary of the invention

[0012] In one embodiment of the present invention, the atomization working mechanism includes an atomization power switch key, a switch start plate, an atomization sterilizer, an aerosol delivery pipe, an atomization nozzle and an atomization spray hole. A rectangular groove is provided on the outer wall of one side of the rectangular movable plate, and an atomization power switch key is provided inside the rectangular groove. A switch start plate matching the atomization power switch key is provided on the outer wall of one side of the rectangular movable plate.

[0014] In one embodiment of the present invention, the mist water storage mechanism includes a water storage box, a fixed handle and a mist water filter hole. The water storage box is placed inside a blood sampling support platform. A plurality of groups of mist water filter holes of the same size are provided on the top of the water storage box. The fixed handle is welded to both ends of the top surface of the water storage box.

[0015] In one embodiment of the present invention, bearing mounting seats are respectively provided on both sides of the outer wall of the space partition plate, and one end of the rotating threaded rod rotates inside the bearing mounting seat.

[0016] In one embodiment of the present invention, the four corners of the bottom surface of the blood sampling support platform are respectively welded with fixed supporting circular columns of the same size, and the bottoms of the four fixed supporting circular columns are respectively provided with rectangular anti-slip pads, and the bottoms of the four rectangular anti-slip pads are all provided with anti-slip grooves.

[0017] In one embodiment of the present invention, a method for using a blood sampling device for intravenous therapy care comprises the following steps: Step 1: The device achieves precise clamping and fixation of the patient's blood vessels through the clamping working mechanism. When the medical staff turns the rotating handle, the rotating threaded rod drives the threaded moving block to move on the fixed sliding track, thereby adjusting the positions of the two sets of rectangular moving plates and the first blood sampling clamping and fixing plates and the second blood sampling clamping and fixing plates thereon.

[0018] Step 2: The rectangular movable plate slides in the rectangular slide groove. At the same time, the buffer telescopic column and the buffer spring provide necessary buffering and stability to ensure moderate clamping force and avoid discomfort to the patient. The mutual attraction between the first NdFeB magnet bar and the second NdFeB magnet bar further enhances the stability of clamping and ensures that the blood vessel will not slip during blood drawing.

[0019] Step 3: Before drawing blood, medical staff can activate the atomizer power switch through the switch starter board to start the atomizer sterilizer. The aerosol generated by the atomizer sterilizer is transported to the atomizer nozzle on the fixed mounting plate through the aerosol delivery pipe, and evenly sprayed on the blood drawing area through the atomizer spray hole to achieve rapid and comprehensive disinfection.

[0020] Step 4: The mist water generated during the disinfection process is collected in a water storage box and initially filtered through the mist water filter holes to prevent impurities from clogging the pipes or affecting subsequent processing. The water storage box is convenient for medical staff to clean and replace regularly to ensure the continued effective operation of the disinfection system.

[0021] Step 5: The cooperation between the latch through hole on the rotating handle and the fixed bayonet pin enables the medical staff to adjust the fixed position of the rotating handle as needed, thereby adjusting the moving range of the threaded moving block and the clamping working mechanism.

[0022] The beneficial effects of the technical solution of the present invention are: Two sets of sampling cavities with the same structure set inside the blood sampling support platform provide convenience for double sample collection. The space partition plate effectively isolates the two sampling cavities to avoid cross contamination between samples, which not only improves the sampling efficiency but also ensures the purity and accuracy of the samples. When using it, patients can complete the collection of multiple samples at one time, reducing the pain of repeated needle sticks.

[0023] The mobile adjustment mechanism achieves precise positioning of the clamping working mechanism through the coordinated action of rotating the handle, fixing the pin, rotating the threaded rod, the threaded moving block and the fixed sliding track. Patients or medical staff can easily adjust the position of the clamping working mechanism to adapt to the location and depth of blood vessels of different patients, and also reduce patient discomfort caused by improper operation.

[0024] The combination of the buffer spring and the buffer telescopic column provides the clamping plate with appropriate elasticity and buffer force, making the clamping process gentler and reducing the patient's pain. The first blood sampling clamping fixing plate and the second blood sampling clamping fixing plate can firmly fix the sampling needle or test tube through the adsorption effect of the first NdFeB magnet bar and the second NdFeB magnet bar to prevent it from falling off or shaking during the sampling process.

[0025] Through the synergistic effect of the atomizer power switch, switch start board, atomizer sterilizer, aerosol delivery pipe and atomizer nozzle, the sampling area can be quickly and effectively disinfected before sampling. The aerosol produced by the atomizer sterilizer is fine and uniform, which can quickly cover and kill bacteria and viruses in the sampling area, thereby reducing the risk of infection.

[0026] The mist water storage mechanism is combined with a water storage box, a fixed handle and a mist water filter hole to effectively collect and filter the excess mist water generated during the disinfection process. The mist water filter hole on the top of the water storage box can prevent large particles of impurities from entering the box, thereby maintaining the cleanliness of the mist water.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] A blood sampling device for intravenous therapy care and a method of using the same will be described below with reference to the accompanying drawings.

[0032] like Figures 1 to 11As shown, an embodiment of the present invention provides a blood sampling device for intravenous treatment nursing, including: a blood sampling support platform 1, a sampling cavity 37, a moving adjustment mechanism 38, an atomization working mechanism 39, a mist water storage mechanism 40 and a clamping working mechanism 44, the blood sampling support platform 1 is provided with two groups of sampling cavities 37 with the same structure, a space partition plate 11 is provided between the two groups of sampling cavities 37, and the two groups of sampling cavities 37 include a moving adjustment mechanism 38, an atomization working mechanism 39, a mist water storage mechanism 40 and a clamping working mechanism 44; The movable adjustment mechanism 38 includes a rotating handle 13, a fixed pin 43, a rotating threaded rod 16, a threaded moving block 17 and a fixed sliding rail 18. One end of the rotating handle 13 passes through the side wall of the blood sampling support platform 1 and is connected to the rotating threaded rod 16. The outer wall of the rotating threaded rod 16 is provided with a threaded moving block 17. The rotating handle 13 is fixedly connected to the side wall of the blood sampling support platform 1 through the fixed pin 43. The bottom of the inner wall of the blood sampling support platform 1 is provided with a fixed sliding rail 18. The structural shape of the fixed sliding rail 18 is set to a rectangle. The bottom of the threaded moving block 17 is provided with a fixed sliding block 19 that matches the fixed sliding rail 18, and the top surface of the threaded moving block 17 is provided with a clamping working mechanism 44.

[0033] In a specific application of the embodiment of the present invention, the blood sampling support platform 1 is the basis of the entire device, and two groups of sampling cavities 37 with the same structure are arranged inside it for accommodating and performing blood sampling operations. The two groups of sampling cavities 37 are isolated by a space partition plate 11 to ensure that the two sampling processes do not interfere with each other, thereby improving the sampling efficiency.

[0034] The moving adjustment mechanism 38 is the key to achieve precise adjustment of the sampling position, including a rotating handle 13, a fixed latch 43, a rotating threaded rod 16, a threaded moving block 17 and a fixed sliding track 18. The operator drives the rotating threaded rod 16 to rotate by rotating the handle 13. Due to the movement principle of the thread, the threaded moving block 17 will move along the axial direction of the rotating threaded rod 16. A fixed slider 19 is provided at the bottom of the threaded moving block 17 to match the fixed sliding track 18 to ensure the stability and accuracy of the threaded moving block 17 during movement. The shape of the fixed sliding track 18 is set to be rectangular to limit the moving direction of the threaded moving block 17 so that it can only move along a specific path.

[0035] The clamping working mechanism 44 is installed on the top surface of the threaded moving block 17 and is used to clamp the patient's venous site to ensure the accuracy and stability of blood sampling. When the threaded moving block 17 moves to the specified position, the clamping working mechanism 44 will automatically or manually adjust to the appropriate clamping force to fix the venous site.

[0036] Before blood sampling, the atomization working mechanism 39 absorbs the mist from the mist storage mechanism 40 and atomizes it into tiny particles and sprays it on the patient's veins. The atomized mist helps to relieve the patient's pain and promotes blood circulation in the veins, making the blood drawing process smoother.

[0037] In a possible embodiment, a plurality of groups of latch holes 14 of the same size are provided on the surface of the rotating handle 13, a side panel fixing through hole 15 matched with one end of the rotating handle 13 is provided on the side wall of the blood sampling support platform 1, and fixing pin through holes 45 matched with the fixing pin 43 are provided on both sides of the side panel fixing through hole 15. The fixing pin 43 passes through the latch through hole 14 and extends to the inside of the fixing pin through hole 45, and one end of the rotating handle 13 passes through the side wall of the blood sampling support platform 1 through the side panel fixing through hole 15.

[0038] In a specific application of the embodiment of the present invention, a plurality of groups of latch through holes 14 of the same size are opened on the surface of the rotating handle 13. These through holes not only provide a path for the fixing pin 43 to pass through, but also allow the operator to select a suitable fixing position according to actual needs. By rotating the rotating handle 13, the position of components related to blood sampling, such as the sampling needle, etc., can be adjusted. The design of the side panel fixing through hole 15 allows one end of the rotating handle 13 to pass through and cooperate with the internal thread or other fixing mechanism, so as to achieve a stable installation of the rotating handle 13 on the platform.

[0039] When the rotating handle 13 is rotated to the desired position, the fixed pin 43 will pass through the selected pin hole 14 and extend to the inside of the fixed pin hole 45 on the side wall of the blood sampling support platform 1. The fixed pin 43 locks the position of the rotating handle 13 to prevent it from accidentally rotating or moving during the blood sampling process.

[0040] In a possible embodiment, the clamping working mechanism 44 includes a buffer spring 21, a buffer telescopic column 22, a rectangular moving plate 23, a first blood sampling clamping fixed plate 24, a second blood sampling clamping fixed plate 25, a first NdFeB magnet bar 26, a second NdFeB magnet bar 27, and a rectangular groove 28. Rectangular grooves 20 are respectively provided at both ends of the top surface of the threaded moving block 17, and two groups of rectangular moving plates 23 are provided on the top of the two rectangular grooves 20. The bottom of the two groups of rectangular moving plates 23 extends to the rectangular grooves 2 0, buffer telescopic columns 22 are respectively provided on both sides of the outer walls of the bottoms of the two groups of rectangular movable plates 23, buffer springs 21 are wound around the outer walls of the buffer telescopic columns 22, a first blood sampling clamping and fixing plate 24 is provided on the top surface of one rectangular movable plate 23, a second blood sampling clamping and fixing plate 25 is provided on the top surface of the other rectangular movable plate 23, a first matching neodymium iron boron magnet bar 26 is provided on the side wall of one rectangular movable plate 23, and a second matching neodymium iron boron magnet bar 27 is provided on the side wall of the other rectangular movable plate 23.

[0041] The outer wall on one side of the threaded moving block 17 is provided with a plurality of first fixed connection holes 31 of the same size, the outer wall on one side of the rectangular moving plate 23 is provided with a second fixed connection hole 32, the interior of the second fixed connection hole 32 is provided with a limiting clamping plate 41, the interior of the second fixed connection hole 32 is inserted with a connecting fixing pin 33, the structural shape of the connecting fixing pin 33 is set to be concave, an auxiliary moving plate 42 is provided on the outer wall of one end of the connecting fixing pin 33, and the other end of the connecting fixing pin 33 is inserted into the interior of the first fixed connection hole 31.

[0042] In a specific application of the embodiment of the present invention, two sets of rectangular movable plates 23 respectively carry the first blood sampling clamping and fixing plate 24 and the second blood sampling clamping and fixing plate 25. The two clamping and fixing plates can firmly clamp the sampling needle or sampling tube, and the combination of the buffer telescopic column 22 and the buffer spring 21 provides the necessary buffering effect for the clamping process. When the sampling tool is clamped, the buffer spring 21 can absorb and disperse the impact force generated during the clamping process, protect the sampling tool from damage, and ensure the stability of the clamping.

[0043] The arrangement of the first NdFeB magnet bar 26 and the second NdFeB magnet bar 27 enables the two groups of rectangular movable plates 23 to be attracted and fixed to each other by magnetic force when closed, further enhancing the stability of clamping. This magnetic fixing method is not only convenient and fast, but also can easily open or adjust the clamping position when needed.

[0044] The sliding design of the rectangular movable plate 23 in the rectangular slide groove 20 allows the operator to adjust the distance between the clamping fixed plates according to actual needs to accommodate sampling tools of different sizes. The first fixed connecting hole 31 on the threaded movable block 17 is connected to the second fixed connecting hole 32 on the rectangular movable plate 23 through a connecting fixing pin 33, thereby realizing a stable connection between the clamping working mechanism 44 and the entire blood sampling device.

[0045] The setting of the limiting card plate 41 prevents the connection fixing pin 33 from accidentally falling off after being inserted into the first fixed connection hole 31, thereby ensuring the stability of the connection. The auxiliary movable plate 42 provides additional operating convenience, allowing the operator to easily insert or remove the connection fixing pin 33.

[0046] In a possible embodiment, the atomization working mechanism 39 includes an atomization power switch key 29, a switch start plate 30, an atomization disinfector 5, an aerosol delivery pipe 6, an atomization nozzle 8 and an atomization spray hole 9. A rectangular groove 28 is provided on the outer wall of one side of a rectangular movable plate 23, and an atomization power switch key 29 is provided inside the rectangular groove 28. A switch start plate 30 matching the atomization power switch key 29 is provided on the outer wall of one side of the rectangular movable plate 23. An atomization disinfector 5 is provided on one side of the outer wall of the blood sampling support platform 1. The atomization disinfector 5 is electrically connected to the atomization power switch key 29 through a conductive line. An atomization disinfector 5 is provided on one side of the atomization disinfector 5. The other end of the aerosol delivery pipe 6 passes through the outer wall of the blood sampling support platform 1. The end of the other end of the aerosol delivery pipe 6 is provided with a fixed mounting plate 7. The surface of the fixed mounting plate 7 is provided with several groups of atomization nozzles 8 of the same size, and the surface of the atomization nozzle 8 is provided with an atomization spray hole 9.

[0047] In a specific application of the embodiment of the present invention, the atomizing power switch key 29 is placed in the rectangular groove 28 provided on the outer wall of one side of the rectangular movable plate 23, which not only protects the switch key from interference from the external environment, but also ensures the convenience of the operator when using it. When it is necessary to start the atomizing disinfection, the operator only needs to lightly touch the switch start plate 30 matched with the atomizing power switch key 29 to trigger the start of the atomizing disinfector 5 by closing the circuit. Once the atomizing disinfector 5 is activated, it will receive the electrical energy from the atomizing power switch key 29 through the conduction line, and start to atomize the internal disinfection liquid. The advanced atomization technology is used inside the atomizing disinfector 5, which can quickly convert the disinfection liquid into aerosol of tiny particles.

[0048] The atomized disinfectant mist is transported to the vicinity of the sampling area of ​​the blood sampling support platform 1 through the aerosol delivery tube 6. The other end of the aerosol delivery tube 6 passes through the outer wall of the blood sampling support platform 1 and is connected to the fixed mounting plate 7. Several groups of atomizing nozzles 8 of the same size are evenly distributed on the surface of the fixed mounting plate 7. These nozzles can spray the disinfectant mist on the blood drawing site in a uniform and delicate manner. Each atomizing nozzle 8 has a tiny atomizing spray hole 9 on its surface. These holes can ensure that the disinfectant mist is evenly sprayed on the blood drawing site in a mist form. The atomized disinfectant particles can quickly penetrate into the skin surface and tiny wounds, effectively killing bacteria, viruses and other microorganisms, thereby achieving the purpose of rapid disinfection.

[0049] In a possible embodiment, a nebulizer sterilizer support fixing plate 4 is welded to the outer wall on one side of the blood sampling support platform 1, and the nebulizer sterilizer 5 is placed above the nebulizer sterilizer support fixing plate 4. A rear fixing plate 10 is welded to the outer wall on the other side of the fixed mounting plate 7, and the other side of the rear fixing plate 10 is welded to the inner wall of the blood sampling support platform 1.

[0050] The mist water storage mechanism 40 includes a water storage box 34, a fixed handle 35 and mist water filtering holes 36. The water storage box 34 is placed inside the blood sampling support platform 1. A plurality of groups of mist water filtering holes 36 of the same size are opened on the top of the water storage box 34. The fixed handle 35 is welded to both ends of the top surface of the water storage box 34.

[0051] In a specific application of the embodiment of the present invention, the atomizer sterilizer 5 in the device is firmly placed on the atomizer sterilizer support fixing plate 4, and the fixing plate is connected to the outer wall of one side of the blood sampling support platform 1 by welding. When blood sampling is required, the operator can start the atomizer sterilizer to atomize the disinfectant liquid into tiny particles, and spray these particles evenly onto the patient's blood drawing site through air flow. The atomization sterilization can not only quickly kill microorganisms such as bacteria and viruses, but also reduce the use of disinfectant liquid and reduce skin irritation.

[0052] During the blood sampling process, part of the mist water generated by the atomizer disinfector will float into the air. In order to collect the mist water, the device is provided with a mist water storage mechanism 40. The mist water storage mechanism 4 consists of a water storage box 34, a fixed handle 35 and a mist water filter hole 36. The water storage box 34 is placed inside the blood sampling support platform 1, and a plurality of groups of mist water filter holes 36 of the same size are opened on the top. The filter holes can not only allow mist water to enter the water storage box, but also effectively block impurities and particulate matter in the air, ensuring that the collected mist water is relatively pure. The fixed handle 35 is welded to both ends of the top surface of the water storage box, so that the operator can easily pull out the water storage box when not in use and clean or replace it.

[0053] The fixed mounting plate 7 is connected to the rear fixing plate 10 by welding, and the other side of the rear fixing plate 10 is welded to the inner wall of the blood sampling support platform 1, which not only enhances the structural strength of the device, but also makes it more stable and reliable during use.

[0054] In a possible implementation manner, bearing mounting seats 12 are respectively provided on both sides of the outer wall of the space partition plate 11 , and one end of the rotating threaded rod 16 rotates inside the bearing mounting seat 12 .

[0055] The four corners of the bottom surface of the blood sampling support platform 1 are welded with fixed support circular columns 2 of the same size, and the bottoms of the four fixed support circular columns 2 are respectively provided with rectangular anti-skid pads 3, and the bottoms of the four rectangular anti-skid pads 3 are all provided with anti-skid patterns.

[0056] In a specific application of an embodiment of the present invention, bearing mounting seats 12 are respectively provided on both sides of the outer wall of the space partition plate 11. The bearing mounting seats provide stable support points for the rotating threaded rod 16, so that the rotating threaded rod can rotate smoothly inside the bearing mounting seats. The space partition plate not only effectively separates the blood sampling area from other areas and reduces the risk of cross infection, but also provides a more focused and private environment for blood sampling.

[0057] The four corners of the bottom surface of the blood sampling support platform 1 are respectively welded with fixed supporting circular columns 2 of the same size. The fixed supporting circular columns serve as the supporting structure of the device to ensure the stability and load-bearing capacity of the blood sampling support platform. By adjusting the rotation position of the rotating threaded rod 16 in the bearing mounting seat, the height of the blood sampling support platform can be fine-tuned to adapt to different heights and operating requirements.

[0058] Rectangular anti-skid pads 3 are respectively provided at the bottom of the four fixed supporting circular columns 2. The anti-skid pads are made of high-quality materials and have anti-skid grooves on the bottom. The anti-skid grooves increase the friction between the anti-skid pads and the ground, effectively preventing safety hazards caused by accidental sliding or tilting of the device during use. Anti-skid not only improves the stability of the device during use, but also provides a safer and more reliable operating environment for the operator and the patient.

[0059] When the present invention is used in practice, the device achieves precise clamping and fixation of the patient's blood vessels through the clamping working mechanism 44. When the medical staff rotates the rotating handle 13, the rotating threaded rod 16 drives the threaded moving block 17 to move on the fixed sliding track 18, thereby adjusting the positions of the two sets of rectangular moving plates 23 and the first blood sampling clamping and fixing plates 24 and the second blood sampling clamping and fixing plates 25 thereon.

[0060] Specifically, the rectangular movable plate 23 slides in the rectangular slide groove 20, and the buffer telescopic column 22 and the buffer spring 21 provide necessary buffering and stability to ensure moderate clamping force and avoid discomfort to the patient. The mutual attraction between the first NdFeB magnet bar 26 and the second NdFeB magnet bar 27 further enhances the stability of clamping and ensures that the blood vessel will not slip during blood drawing.

[0061] Specifically, before drawing blood, medical staff can activate the atomizing power switch 29 through the switch starter board 30, thereby starting the atomizing disinfector 5. The aerosol generated by the atomizing disinfector 5 is transported to the atomizing nozzle 8 on the fixed mounting plate 7 through the aerosol transport pipe 6, and is evenly sprayed on the blood drawing area through the atomizing spray hole 9, so as to achieve rapid and comprehensive disinfection.

[0062] Specifically, the mist water generated during the disinfection process is collected in the water storage box 34 and is initially filtered through the mist filter holes 36 to prevent impurities from clogging the pipeline or affecting subsequent processing. The water storage box 34 is convenient for medical staff to clean and replace regularly to ensure the continued effective operation of the disinfection system.

[0063] Specifically, the cooperation between the latch through hole 14 on the rotating handle 13 and the fixed latch 43 enables medical personnel to adjust the fixed position of the rotating handle 13 as needed, thereby adjusting the moving range of the threaded moving block 17 and the clamping working mechanism 44 .

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
