Description

Technical Field

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

[0002] Blood contains a wealth of biological information. Collecting blood for various laboratory tests can help doctors diagnose a variety of diseases. However, in the existing blood collection process, the patient's arm is usually placed flat on the blood collection pad, and the patient must ensure that the arm does not move during the blood collection process. There is a lack of additional fixation measures. During the blood collection process, the patient may move his arm due to tension, discomfort or unconscious movements. For example, the patient will instinctively retract his hand when the needle is inserted for blood collection, or unconsciously adjust the arm position due to maintaining a posture for a long time. This movement can cause the blood collection needle to shift, puncture the blood vessel wall or fall out of the blood vessel, causing blood collection failure and requiring re-puncture, increasing the patient's pain and the workload of medical staff.

[0003] At the same time, the blood collection pillow is usually designed to be smaller in size to facilitate placement on the blood collection table. Its length and width may not be sufficient to fully support the patient's entire arm, causing most of the arm to exceed the range of the blood collection pillow and be suspended in the air. In the suspended state, the arm lacks sufficient support and is more susceptible to external factors and shaking. Shaking of the arm can cause increased pain at the puncture site, increase the risk of vascular damage, and increase the difficulty and risk of blood collection.

[0004] To this end, a blood collection auxiliary device is proposed. Summary of the invention

[0014] Further, a hook is provided at the bottom end of the bottom contact pipe. The inner groove and the U-shaped block are located on the moving path of the hook of the bottom contact pipe.

[0015] Further, the atomizing pump head is located on the moving path of the trigger rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The patient's arm is fixed in a three-point manner by the annular airbag and the two semi-circular airbags. The patient's forearm and upper arm are both wrapped and limited and in contact with the semi-circular airbags, being in a state with a bottom support. Therefore, the patient cannot move the arm freely, which can ensure that the blood collection process will not be affected by the movement of the patient's arm, resulting in the displacement of the blood collection needle, and ensuring the comfort of the patient during the blood collection process and the smoothness of the blood collection work.

[0018] The patient's arm is supported in a three-point manner by the inflated annular airbag and the two semi-circular airbags, avoiding the problem that the patient's arm is in a suspended state during the existing blood collection process and is easily affected by external factors and shakes, ensuring the stability of the patient's arm during the blood collection process and at the same time guaranteeing the safety of the patient's blood collection work.

[0019] The inflated annular airbag applies uniform inward pressure to the required pulse position of the patient, and then the annular airbag plays a role similar to a "compression cuff" for the patient. Compared with the traditional compression cuff, the pressure distribution of the annular airbag is more uniform, and there will be no local excessive or low pressure, thereby improving the effect of venous filling. At the same time, the annular airbag can simultaneously realize the functions of arm fixation and "compression cuff", reducing the operation steps and the required time. Medical staff do not need to use traditional fixation devices and compression cuffs separately, which improves work efficiency. In emergency situations, such as rescuing patients or taking blood quickly, the time saved may have an important impact on the treatment and diagnosis of patients;

[0020] The patient's arm is fixed by inflating the annular airbag and two semi-annular airbags, and the medical staff can control the expansion degree of the annular airbag and the two semi-annular airbags by controlling the micro air pump, and adjust the position of the semi-annular airbag by telescopic tube one, and adjust it according to the specific situation of the patient. For patients of different ages, body shapes, and conditions, the pressure level can be adjusted to a suitable level, which can achieve good venous filling and arm fixation effects without causing excessive pressure on the patient. At the same time, the soft characteristics of the rubber material of the annular airbag and the semi-annular airbag and the uniform pressure can reduce the pressure on the patient's arm. Compared with the traditional compression cuff, the annular airbag will not produce excessive pressure locally, thereby reducing the patient's discomfort.

[0021] The patient's blood collection site is wiped and disinfected twice in a circular manner using an iodine cotton ball, and the process is driven by a micro air pump, which shares the driving source with the pulse compression arm support assembly. The traditional blood collection disinfection process requires medical staff to manually pick up the iodine cotton ball for wiping and then dispose of the waste, while here the disinfection and sterilization steps can be automatically completed while the annular airbag and semi-annular airbag are inflated, which greatly saves operation time. In a busy medical environment, especially when facing a large number of patients who need blood collection, it can significantly improve work efficiency.

[0022] During the movement of the hook of the bottom contact tube, an automatic loading and unloading operation of the iodine cotton balls is formed, and the discarded iodine cotton balls are collected into the discharge tube, which avoids direct contact between medical staff and discarded iodine cotton balls and reduces the risk of cross infection. The automatic loading operation can be started immediately when the annular airbag and the semi-annular airbag are inflated, and the iodine cotton balls are quickly pushed to the patient's blood collection site for disinfection. Medical staff do not need to manually prepare the iodine cotton balls, which saves time in finding and taking the iodine cotton balls, making the entire blood collection process more compact and efficient. The automatic loading operation can realize the uninterrupted supply of new iodine cotton balls, ensuring that after the blood collection of one patient is completed, it can be immediately prepared for the next patient. This continuous operation capability avoids the interruption of operation caused by the untimely supply of iodine cotton balls, so that the blood collection work can proceed smoothly. Through;

[0023] The disinfectant is pumped out from the liquid storage tank through the atomizing pump head and sprayed to the outside through the atomizing pump head. The atomized disinfectant is sprayed on the blood collection environment and the internal structure of the pulse compression arm support component and the sterilization replacement component to ensure the continuous use of the two components. The spraying is done when the patient has just finished the blood collection work, which can ensure the timeliness of disinfection and effectively block the transmission of the disease. Reduce the survival and spread of pathogens in the environment, reduce the risk of infection for other patients and medical staff, and there is no need to wait for medical staff to arrange time for disinfection operations. This can achieve continuous work and improve the work efficiency of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiments provided by the present invention:

[0041] Embodiment 1:

[0042] See also Figures 1 to 3 As shown, a blood collection auxiliary device includes a compression arm support assembly, which is used to fix the patient's arm and act as a compression belt. The compression arm support assembly includes a base plate 11 and an annular airbag 12. The base plate 11 is a cavity structure. A through hole is opened on the base plate 11. The annular airbag 12 is fixedly connected in the through hole of the base plate 11. Two telescopic tubes 13 are symmetrically fixedly connected to the bottom of the base plate 11 on both sides, and the telescopic ends of the two telescopic tubes 13 are respectively fixedly connected to a bottom support 14. The top ends of the two bottom supports 14 are respectively fixedly connected to a semi-ring airbag 15. A micro air pump 16 is installed on the top surface of the base plate 11, and the air outlet end of the micro air pump 16 is fixedly connected to a double-headed connecting tube 17, and the top surface of the double-headed connecting tube 17 is fixedly connected to an air pipe 18.

[0043] It should be noted that the blood collection location in the following text is the patient's elbow, which is the commonly used location for venous blood collection.

[0044] Among them: the air pipe 18 is connected to the base plate 11, the base plate 11 is connected to the annular airbag 12 and the telescopic tube 13 respectively, the telescopic tube 13 is connected to the bottom bracket 14, and the bottom bracket 14 is connected to the semi-annular airbag 15.

[0045] When the pulse compression arm support assembly is in use, the patient passes his arm through the inner ring surface of the annular airbag 12. When the elbow of the arm passes through the inner ring surface of the annular airbag 12, the medical staff confirms that the position of the inner ring surface of the annular airbag 12 coincides with the pulse compression position required by the patient. Then the patient places his forearm and upper arm flat on the inner ring surfaces of the two semi-annular airbags 15. Then the patient stretches or contracts the telescopic end of the telescopic tube 13 according to the length of his arm, so that the bottom support 14 drives the semi-annular airbag 15 to move at the bottom of the patient's arm. When the semi-annular airbag 15 moves to a comfortable position for the patient, the medical staff starts the micro air pump 16 to discharge air, and the airflow enters the interior of the annular airbag 12 through the trachea 18, and enters the interior of the semi-annular airbag 15 through the telescopic tube 13 and the bottom support 14. Then the annular airbag 12 and the two semi-annular airbags 15 are inflated at the same time. When the patient feels the inward squeezing force when inflated, the medical staff turns off the micro air pump 16.

[0046] As the two semi-circular airbags 15 expand, the front side of the patient's forearm and upper arm are half-wrapped by the semi-circular airbags 15, and the annular airbag 12 located at the position where the patient needs pulse pressure wraps the front side of the patient's upper arm in a circular shape and uniformly applies inward pressure to the patient's upper arm. At this time, the patient's arm is fixed in a three-point manner by the annular airbag 12 and the two semi-circular airbags 15, and the patient's forearm and upper arm are both wrapped and limited and in conflict with the semi-circular airbags 15, and are in a state of having a bottom support, so that the patient cannot move his arm freely, which can ensure that the blood collection needle will not be displaced due to the movement of the patient's arm during the blood collection process, thereby ensuring the patient's comfort during the blood collection process and the smoothness of the blood collection work.

[0047] The patient's arm is supported at three points by the inflated annular airbag 12 and two semi-annular airbags 15, which can solve the problem that the patient's arm is in a suspended state and is easily shaken by external factors during the existing blood collection process, thereby ensuring the stability of the patient's arm during the blood collection process and ensuring the safety of the patient's blood collection work.

[0048] At this time, since the inflated annular airbag 12 applies uniform inward pressure to the patient's required pulse position, the annular airbag 12 plays a role similar to a "compression cuff" compared to the patient. Compared with the traditional compression cuff, the pressure distribution of the annular airbag 12 is more uniform, and there will be no local pressure that is too high or too low, thereby improving the effect of venous filling. At the same time, the annular airbag 12 can simultaneously realize the functions of arm fixation and "compression cuff", reducing the operation steps and the time required. Medical staff do not need to use traditional fixation devices and compression cuffs separately, thereby improving work efficiency.

[0049] The patient's arm is fixed by inflating the annular airbag 12 and the two semi-annular airbags 15, and the medical staff can control the expansion degree of the annular airbag 12 and the two semi-annular airbags 15 by controlling the micro air pump 16, and adjust the position of the semi-annular airbag 15 by the telescopic tube 13, and adjust it according to the specific situation of the patient. For patients of different ages, body shapes, and conditions, the pressure level can be adjusted to a suitable level, which can achieve good venous filling and arm fixation effects without causing excessive pressure on the patient. At the same time, the soft properties and uniform pressure of the rubber material of the annular airbag 12 and the semi-annular airbag 15 can reduce the sense of pressure on the patient's arm. Compared with the traditional compression cuff, the annular airbag 12 will not produce excessive pressure locally, thereby reducing the patient's discomfort.

Through holes are only opened on the bottom surface of the semi-circular sliding plate 218 on the side close to the annular airbag 12. The bottom end of the bottom special-shaped tube 216 faces upward above the bottom platform 220.

[0059] Among them: a hook is set at the bottom end of the bottom contact tube 210, the inner groove 221 and the U-shaped block 224 are both located on the moving path of the hook of the bottom contact tube 210, and in the initial state, the tip of the hook faces the side of the U-shaped block 224, and the function of the spring 1 211 is to ensure that the height of the bottom end of the bottom contact tube 210 can adapt to patients with different arm thicknesses.

[0060] When the sterilization replacement component is in use, during the operation of the pulse compression arm support component, the patient has laid his arm flat, and the micro air pump 16 has not started to inflate, the details are as follows:

[0061] At this time, the patient's arm passes through the inner ring surface of the annular airbag 12 at the elbow of the patient, and the patient has adjusted the position of the semi-annular airbag 15. Therefore, the position of the patient's elbow blood collection point is determined. At this time, the medical staff extends the telescopic end of the telescopic tube 21 so that the electric contact block 25 is located directly above the patient's blood collection point. Then the medical staff starts the micro air pump 16. At this time, the airflow flows into the elastic long airbag 28 through the trachea 23, so that the elastic long airbag 28 is inflated and stretched. While the elastic long airbag 28 stretches, it pushes the top sliding tube 29 to slide inside the guide plate 24. While the top sliding tube 29 moves, it drives the bottom contact tube 210 to move synchronously in the direction of the rotating plate 217. During the movement of the bottom contact tube 210, the rotating plate 217 is pushed on the special-shaped support frame 214 Rotate, at this time, the torsion spring 219 undergoes elastic deformation, and during the rotation of the rotating plate 217, it drives the semi-annular slide plate 218 to rotate to the side away from the patient's arm. As the semi-annular slide plate 218 rotates, the through hole on the bottom surface of the semi-annular slide plate 218 rotates to a position where the top storage tube 215 and the bottom special-shaped tube 216 are close to each other, and then under the action of gravity, the iodine cotton ball 223 will fall from the inside of the top storage tube 215 into the inside of the bottom special-shaped tube 216, and fall to the top surface of the base 220 through the bottom special-shaped tube 216. When the bottom contact tube 210 moves to a point where it does not conflict with the rotating plate 217, under the elastic reset action of the torsion spring 219, the rotating plate 217 rotates and resets. At this time, the semi-annular slide plate 218 blocks the bottom end of the top storage tube 215.

[0062] At this time, the moving curved hook of the bottom contact tube 210 contacts the iodine cotton ball 223 located on the base 220, and the curved hook of the bottom contact tube 210 pushes the iodine cotton ball 223 to move toward the patient's arm. During this process, the curved hook will also drive the iodine cotton ball 223 to pass through the inner groove 221. At this time, the inner groove 221 contacts the iodine cotton ball 223, causing the iodine cotton ball 223 to deform, which is equivalent to pushing the iodine cotton ball 223 inward on the curved hook, that is, the iodine cotton ball 223 covers the curved hook to prevent the iodine cotton ball 223 from falling off naturally as the bottom contact tube 210 moves.

[0063] During the movement of the bottom contact tube 210, the bottom slide bar 213 slides synchronously on the top surface of the side slide plate 212. At this time, the bottom contact tube 210 does not extend downward due to the interference between the bottom slide bar 213 and the side slide plate 212. At this time, the spring 1 211 is in an elastically compressed state. When the bottom contact tube 210 moves to the vicinity of the patient's elbow fossa, the bottom slide bar 213 slides on the side slide plate 212 to the inclined position, and then under the elastic extension action of the spring 1 211, the bottom contact tube 210 drives the iodine cotton ball 223 to synchronously descend until it interferes with the patient's arm. At this time, the elastic long airbag 28 continues to be inflated, and it will continue to push the top slide tube 29, so that the top slide tube 29 enters the guide plate 2 4's vortex groove b, at this time, the top sliding tube 29 drives the bottom contact tube 210 and the iodine cotton ball 223 to move synchronously along the vortex groove b, which will make the iodine cotton ball 223 touch the patient's elbow skin. Under the action of the iodine cotton ball 223 squeezing the skin, iodine will seep out to disinfect the patient's elbow. At this time, the movement trajectory of the iodine cotton ball 223 at the patient's elbow is a rotation that gradually shrinks from a large circle to a small circle. When the top sliding tube 29 slides inside the vortex groove b of the guide plate 24 until it contacts the electric contact block 25, the contraction end of the electric telescopic rod 26 will drive the ring sealing plate 27 to move upward to block the trachea 23. However, since the sealing plate thickness of the ring sealing plate 27 is thinner than the ring tube, the sealing plate will only block The trachea 23 will not block the elastic long airbag 28, so that the elastic long airbag 28 is connected to the outside. At this time, the air flow inside the elastic long airbag 28 flows to the outside. Under the action of the elastic contraction of the elastic long airbag 28, the top sliding tube 29 is pulled to move in the opposite direction inside the guide plate 24. In this process, the movement trajectory of the iodine cotton ball 223 at the patient's elbow fossa is a rotation from a small circle to a large circle, until the top sliding tube 29 enters the straight groove of the guide plate 24. At this time, the bottom sliding bar 213 moves to the inclined surface of the side sliding plate 212 and is squeezed to slide upward. At this time, the bottom sliding bar 213 pulls the bottom contact tube 210 to lift upward, and the spring 1 211 is elastically compressed, which will also make the iodine cotton ball 223 no longer contact with the patient. The bottom contact tube 210 pushes the rotating plate 217 to rotate when the bottom contact tube 210 moves in the reverse direction, so that the semi-annular slide plate 218 rotates in the reverse direction. However, since the through hole is only provided on one side of the semi-annular slide plate 218, the top storage tube 215 is not connected with the inside of the bottom special-shaped tube 216 during the reverse rotation. When the hook drives the iodine cotton ball 223 to move in the reverse direction to the position of the U-shaped block 224, the hook passes through the inside of the U-shaped block 224, but the iodine cotton ball 223 is blocked by the U-shaped block 224 and falls off the hook. At this time, the iodine cotton ball 223 falls into the discharge tube 222 under the action of gravity and is discharged into the external collection box. At this time, the disinfection and sterilization of the patient is completed, and the medical staff can draw blood from the patient.

[0064] In the above process, the patient's blood collection site is wiped and disinfected twice in a circular manner using the iodine cotton ball 223, and the process is driven by the micro air pump 16, that is, the driving source is shared with the pulse compression arm support assembly. The traditional blood collection disinfection process requires medical staff to manually pick up the iodine cotton ball 223 for wiping and then dispose of the waste. Here, the disinfection and sterilization steps can be automatically completed while the annular airbag 12 and the semi-annular airbag 15 are inflated, which greatly saves operation time. In a busy medical environment, especially when facing a large number of patients who need blood collection, it can significantly improve work efficiency.

[0065] During the movement of the hook of the bottom contact tube 210, an automatic loading and unloading operation of the iodine cotton balls 223 is formed, and the discarded iodine cotton balls 223 are collected into the discharge pipe 222, avoiding direct contact between medical staff and the iodine cotton balls 223 and discarded iodine cotton balls 223, reducing the risk of cross infection, and the automatic loading operation can be started immediately when the annular airbag 12 and the semi-annular airbag 15 are inflated, and the iodine cotton balls 223 are quickly pushed to the patient's blood collection site for disinfection. There is no need for medical staff to manually prepare the iodine cotton balls 223, saving time in searching for and taking the iodine cotton balls 223, making the entire blood collection process more compact and efficient, and the automatic loading operation can realize the uninterrupted supply of new iodine cotton balls 223, ensuring that after blood collection from one patient is completed, it can be prepared for the next patient immediately. This continuous operation capability avoids operation interruptions caused by untimely supply of iodine cotton balls 223, allowing blood collection work to proceed smoothly.

[0066] Example 2: Please refer to Figure 10 to Figure 11 As shown, two environmental disinfection components for automatically disinfecting the environment and structure after the blood collection work is completed are symmetrically arranged on the base plate 11, and the environmental disinfection component includes a spring 2 31, and the spring 2 31 is fixedly connected between the base plate 11 and the base bracket 14, and a trigger rod 32 is fixedly connected to the bottom of the base bracket 14 near the base plate 11, and a liquid storage tank 33 is fixedly connected to the bottom of the base plate 11 near the trigger rod 32. The top surface of the liquid storage tank 33 is provided with a filling port, and a filling cap 34 is clamped in the filling port. An atomizing pump head 35 is fixedly connected to the side of the liquid storage tank 33 near the trigger rod 32.

[0067] Among them: medical staff can pull out the filling cap 34 to add disinfectant into the liquid storage tank 33, and the suction tube of the atomizing pump head 35 is connected to the inside of the liquid storage tank 33.

[0068] Wherein: the atomizing pump head 35 is located on the moving path of the trigger rod 32 .

[0069] Among them: in the initial state, the trigger rod 32 presses the atomizing pump head 35, that is, the distance between the bottom bracket 14 and the base plate 11 is the smallest, and when the user adjusts the distance, only the second spring 31 can be stretched.

[0070] Among them: the environmental disinfection components are set into two groups, one group close to the sterilization replacement component is used to disinfect the internal structure of the sterilization replacement component, and the other environmental disinfection component is used to disinfect the blood collection environment.

[0071] When the environmental disinfection component is in use, the patient's arms are placed on the two semi-ring airbags 15, and the distance between the base support 14 and the base plate 11 is adjusted so that the trigger rod 32 no longer presses against the atomizing pump head 35, and as the patient adjusts, the spring 2 31 is elastically stretched. At this time, since the patient's arm applies downward pressure to the base support 14, the spring 2 31 is elastically stretched during the blood collection process, and then the patient performs blood collection.

[0072] When the patient completes the blood collection, the medical staff extracts the air inside the annular airbag 12 and the semi-annular airbag 15 through the micro air pump 16, and resets the electric telescopic rod 26 through the external controller, and then manually resets the telescopic tube 21. At this time, the patient can pull his arm out of the inner ring surface of the annular airbag 12. At this time, the spring 2 31 elastically contracts, pulling the base support 14 to move toward the base plate 11, and causing the telescopic end of the telescopic tube 13 to contract. During this process, the trigger rod 32 moves synchronously with the base support 14, and the trigger rod 32 resists and presses the atomizing pump head 35, so that the atomizing pump head 35 pumps out disinfectant from the liquid storage tank 33, and atomizes and sprays it to the outside through the atomizing pump head 35. The atomized disinfectant is sprayed on the blood collection environment and the internal structure of the pulse compression arm support assembly and the sterilization replacement assembly, ensuring the continuous use of the two components, and the spraying is when the patient has just finished the blood collection work, which can ensure the timeliness of disinfection and effectively block the transmission route of the disease. Reduce the survival and spread of pathogens in the environment, reduce the risk of infection for other patients and medical staff, and eliminate the need to wait for medical staff to arrange time for disinfection operations. This allows for continuous work and improves the work efficiency of medical staff.
