Description

Technical Field

[0001] This invention belongs to the field of medical device technology and provides a blood collection device. Background Technology

[0002] In medical treatment, some patients require simultaneous arterial blood gas analysis and laboratory blood collection due to their condition. This usually requires two punctures, which not only causes pain for the patient but also delays the sample delivery time and affects the efficiency of medical staff. To avoid this, medical staff may choose direct arterial puncture to collect the blood gas analysis sample, and then use a sterile syringe to collect other laboratory samples. However, this often results in hemolysis of the sample, subcutaneous hematoma, ecchymosis, thrombosis, or even failed collection, causing more harm to the patient. Therefore, there is a need for a blood collection device that is convenient for medical staff to use. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a blood collection device that aims to solve the problem that existing blood collection devices are prone to causing discomfort to patients during use.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides a blood collection device, including a blood collection needle mechanism, a placement box, a blood gas needle mechanism, a vacuum negative pressure blood vessel, and a sealing plug;

[0006] The placement box includes a box body, a fixing block, a pull ring, a guide rod, a spring, a top block, a rotating frame, and a mounting frame. The box body is disposed on one side of the blood collection needle mechanism. The fixing block is fixedly connected to the box body and located on the side of the box body. The pull ring is disposed on the side of the fixing block away from the box body. The guide rod is fixedly connected to the pull ring and slidably connected to the box body, and located on one side of the pull ring. The spring is fixedly connected to the fixing block and located on one side of the fixing block. The top block is fixedly connected to the guide rod and slidably connected to the box body. The rotating frame is slidably connected to the top block and rotatably connected to the box body, and located on one side of the box body. The mounting frame is fixedly connected to the rotating frame and located on the side of the rotating frame. The blood gas needle mechanism is slidably connected to the mounting frame and located on the side of the mounting frame. The vacuum negative pressure blood vessel is disposed on one side of the mounting frame. The sealing plug is disposed on the side of the box body.

[0007] Furthermore, the blood collection needle mechanism includes a transfusion tube, a needle tube, and a needle tip. The transfusion tube is located on the side of the blood gas needle mechanism. The needle tube communicates with the transfusion tube and is located at the top of the transfusion tube. The needle tip communicates with the needle tube and is located at the top of the needle tube.

[0008] Furthermore, the blood collection needle mechanism also includes a protective cover, which is slidably connected to the needle and located on top of the needle.

[0009] Furthermore, the placement box also includes a soft pad, which is fixedly connected to the mounting bracket and located on one side of the mounting bracket.

[0010] Furthermore, the blood gas needle mechanism includes a connecting tube, a syringe, a piston, and a pressing rod. The connecting tube is connected to the infusion tube and is located on the side of the connecting tube. The syringe is connected to the connecting tube and is located at the bottom of the connecting tube. The piston is slidably connected to the syringe and is located inside the syringe. The pressing rod is fixedly connected to the piston and is located on one side of the piston.

[0011] Furthermore, the vacuum negative pressure blood vessel includes a blood collection tube and a sealing plug. The blood collection tube is disposed on one side of the mounting frame, and the sealing plug is fixedly connected to the blood collection tube and located on top of the blood collection tube.

[0012] Furthermore, the vacuum negative pressure blood vessel also includes a tag, which is fixedly connected to the blood collection tube and located on the side of the blood collection tube.

[0013] The beneficial effects of this invention are as follows: When blood collection is required, the blood gas needle mechanism and the vacuum negative pressure blood vessel are first placed on the mounting frame and fixed. At this time, medical personnel can collect blood from the patient through the blood collection needle mechanism, allowing blood to enter the blood collection needle mechanism. Simultaneously, the medical personnel can connect the blood collection needle mechanism to the blood gas needle mechanism, allowing blood to enter the blood gas needle mechanism. After a suitable amount of blood has been collected in the blood gas needle mechanism, the blood collection needle mechanism can be removed. At this time, the medical personnel can hold the blood collection needle mechanism with one hand and place the sealing plug on the side of the placement box on the top of the blood gas needle mechanism with the other hand to seal the blood gas needle mechanism and prevent air from entering the blood gas needle mechanism, which would affect the quality of the blood. Then, the medical personnel can connect the blood collection needle mechanism to the vacuum negative pressure blood vessel and begin collecting blood through the vacuum negative pressure blood vessel. Blood is collected within the blood collection needle mechanism. After a suitable amount is collected, medical personnel remove the blood collection needle mechanism and process it. Simultaneously, medical personnel can pull the pull ring, causing the guide rod to slide within the fixed block, moving the top block and compressing the spring. This allows the top block to slide out of the rotating frame, no longer blocking it, allowing medical personnel to rotate the rotating frame. This causes the mounting frame to rotate as well, rotating the blood gas needle mechanism and the vacuum negative pressure blood vessel, reversing the flow of blood and preventing hemolysis or coagulation, thus facilitating blood testing. After rotation, medical personnel release the pull ring, causing the spring to stretch and push the top block into the rotating frame, stopping it from rotating further. This solves the problem of discomfort caused to patients by existing blood collection devices.

The blood gas needle mechanism 103 includes a connecting tube 119, a syringe 120, a piston 121, and a pressing rod 122. The vacuum negative pressure blood vessel 104 includes a blood collection tube 123, a sealing plug 124, and a label 125. The aforementioned solution solves the problem that existing blood collection devices are inconvenient for medical personnel to use.

[0025] In this specific embodiment, the box body 106 is disposed on one side of the blood collection needle mechanism 101. The fixing block 107 is fixedly connected to the box body 106 and located on the side of the box body 106. The pull ring 108 is disposed on the side of the fixing block 107 away from the box body 106. The guide rod 109 is fixedly connected to the pull ring 108 and slidably connected to the box body 106, and located on one side of the pull ring 108. The spring 110 is fixedly connected to the fixing block 107 and located on one side of the fixing block 107. The top block 111 is fixedly connected to the guide rod 109 and slidably connected to the box body 106. The rotating frame 112 is slidably connected to the top block 111 and to the box body 106. The 06 rotating connection is located on one side of the housing 106. The mounting bracket 113 is fixedly connected to the rotating bracket 112 and located on the side of the rotating bracket 112. The blood gas needle mechanism 103 is slidably connected to the mounting bracket 113 and located on the side of the mounting bracket 113. The vacuum negative pressure blood vessel 104 is located on one side of the mounting bracket 113. The sealing plug 105 is located on the side of the housing 106. When blood collection is required, the blood gas needle mechanism 103 and the vacuum negative pressure blood vessel 104 are first placed on the mounting bracket 113 and fixed. At this time, medical personnel can collect blood from the patient through the blood collection needle mechanism 101, allowing blood to enter the blood collection needle mechanism 101. At the same time, the medical personnel... Personnel can connect the blood collection needle mechanism 101 to the blood gas needle mechanism 103, allowing blood to enter the blood gas needle mechanism 103. After collecting an appropriate amount of blood in the blood gas needle mechanism 103, the blood collection needle mechanism 101 can be removed from the blood gas needle mechanism 103. At this time, the medical personnel can hold the blood collection needle mechanism 101 with one hand and place the sealing plug 105 on the side of the placement box 102 on the top of the blood gas needle mechanism 103 with the other hand to seal the blood gas needle mechanism 103 and prevent air from entering the blood gas needle mechanism 103, which would affect the quality of the blood. At this time, the medical personnel can connect the blood collection needle mechanism 101 to the vacuum negative pressure blood vessel 104, and then... 4. Blood collection begins within the blood collection needle mechanism 101. Once a suitable amount has been collected, medical personnel remove the blood collection needle mechanism 101 and process it. Simultaneously, medical personnel can pull the pull ring 108, causing the guide rod 109 to slide within the fixed block 107, moving the top block 111 and compressing the spring 110. This allows the top block 111 to slide out of the rotating frame 112, no longer blocking it. Medical personnel can then rotate the rotating frame 112, causing the mounting frame 113 to rotate as well. This causes the blood gas needle mechanism 103 and the vacuum negative pressure blood vessel 104 to rotate, reversing the flow of blood and preventing hemolysis or coagulation.This facilitates blood testing. After rotation, medical personnel release the pull ring 108, causing the spring 110 to stretch and push the top block 111 into the rotating frame 112, thus holding the rotating frame 112 in place and preventing it from continuing to rotate. This solves the problem of discomfort caused to patients by existing blood collection devices.

[0026] The transfusion tube 114 is located on the side of the blood gas needle mechanism 103. The needle tube 115 is connected to the transfusion tube 114 and is located at the top of the transfusion tube 114. The needle tip 116 is connected to the needle tube 115 and is located at the top of the needle tube 115. When blood needs to be drawn, the needle tip 116 is first inserted into the patient's blood collection site, and the transfusion tube 114 is connected to the blood gas needle mechanism 103, so that the patient's blood flows through the needle tip 116, from the needle tube 115 to the transfusion tube 114, and from the transfusion tube 114 to the blood gas needle mechanism 103.

[0027] Secondly, the protective cover 117 is slidably connected to the needle 116 and is located on top of the needle 116. The protective cover 117 can protect the needle 116 and prevent it from being damaged.

[0028] Furthermore, the soft pad 118 is fixedly connected to the mounting frame 113 and is located on one side of the mounting frame 113. The soft pad 118 can protect the blood gas needle mechanism 103 and the vacuum negative pressure blood vessel 104, preventing them from being damaged during long-term placement.

[0029] Additionally, the connecting tube 119 communicates with the infusion tube 114 and is located on the side of the connecting tube 119. The syringe 120 communicates with the connecting tube 119 and is located at the bottom of the connecting tube 119.

The pressing rod 122 is fixedly connected to the piston 121 and is located on one side of the piston 121, connecting the connecting tube 119 with the infusion tube 114, allowing blood to pass through the infusion tube 114 and enter the syringe 120 through the connecting tube 119. Within 20 minutes, when a certain amount of blood has been collected in the syringe 120, the medical personnel can pull out the infusion tube 114 from the connecting tube 119, hold the infusion tube 114 with one hand, and place the sealing plug 105 into the connecting tube 119 with the other hand to seal the connecting tube 119. During testing, the medical personnel remove the sealing plug 105 from the connecting tube 119 and push the pressing rod 122 to move the piston 121, squeezing out the blood in the syringe 120, thus facilitating blood testing.

[0030] Then, the blood collection tube 123 is disposed on one side of the mounting frame 113, and the sealing plug 124 is fixedly connected to the blood collection tube 123 and located at the top of the blood collection tube 123. After the blood gas needle mechanism 103 completes the blood collection, the medical personnel can insert the infusion tube 114 into the sealing plug 124 so that the blood can enter the blood collection tube 123 through the infusion tube 114 and the blood is collected through the blood collection tube 123, which facilitates the subsequent operations of the medical personnel.

[0031] Furthermore, the label 125 is fixedly connected to the blood collection tube 123 and located on the side of the blood collection tube 123.

[0035] The connecting ring 127 can cover the connection between the rotating frame 112 and the box 106, preventing foreign objects from entering and jamming the top block 111, thus affecting the use of the top block 111.

[0036] The working principle of this invention is as follows: When blood collection is required, the blood gas needle mechanism 103 and the vacuum negative pressure blood vessel 104 are first placed on the mounting frame 113 and fixed. At this time, medical personnel can collect blood from the patient through the blood collection needle mechanism 101, allowing blood to enter the blood collection needle mechanism 101. Simultaneously, medical personnel can connect the blood collection needle mechanism 101 to the blood gas needle mechanism 103, allowing blood to enter the blood gas needle mechanism 103. After a suitable amount of blood is collected in the blood gas needle mechanism 103... The blood collection needle mechanism 101 can be removed from the blood gas needle mechanism 103. At this time, the medical personnel can hold the blood collection needle mechanism 101 with one hand and place the sealing plug 105 on the side of the placement box 102 onto the top of the blood gas needle mechanism 103 with the other hand to seal the blood gas needle mechanism 103 and prevent air from entering and affecting the blood quality. Then, the medical personnel can connect the blood collection needle mechanism 101 to the vacuum negative pressure blood vessel 104 and begin blood collection through the vacuum negative pressure blood vessel 104. Blood is collected within the blood collection needle mechanism 101. After a suitable amount is collected, medical personnel remove the blood collection needle mechanism 101 and process it. Simultaneously, medical personnel can pull the pull ring 108, causing the guide rod 109 to slide within the fixed block 107, moving the top block 111 and compressing the spring 110. This causes the top block 111 to slide out of the rotating frame 112, no longer blocking it, allowing medical personnel to rotate the rotating frame 112 and move the safety device. The mounting frame 113 rotates, causing the blood gas needle mechanism 103 and the vacuum negative pressure blood vessel 104 to rotate as well, inverting the blood within them to prevent hemolysis or coagulation, thus facilitating blood testing. After rotation is complete, medical personnel release the pull ring 108, causing the spring 110 to stretch and push the top block 111 into the rotating frame 112, holding the rotating frame 112 in place and preventing it from continuing to rotate. This solves the problem of discomfort that existing blood collection devices can cause to patients during use.
