Description

Technical Field

[0001] This utility model relates to a blood collection device. More specifically, this utility model relates to a venous vacuum blood collection device. Background Technology

[0002] Venous blood collection is commonly used for routine patient admission examinations and during emergency treatment to provide doctors with a basis for treatment. Depending on the patient's condition, it may require one or multiple tubes of blood to be collected. Traditional blood collection needles are usually used individually, requiring separate operation for each blood collection, which is inefficient. When multiple samples need to be collected, the tail needle needs to be changed repeatedly, which is cumbersome and increases the risk of infection and operational errors. In existing technology, there is a design with one puncture needle connected to multiple tail needles, but this connection method may cause the extension tube to become kinked during use, affecting the blood collection effect. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide a venous vacuum blood collection device that can collect multiple tubes of blood samples at once, avoiding frequent tube changes during blood collection and improving blood collection efficiency and safety.

[0005] To achieve these objectives and other advantages according to the present invention, a venous vacuum blood collection device is provided, comprising a transparent flexible tube and a puncture needle connected to the tip of the transparent flexible tube; wherein, it further comprises:

[0006] At least one tail needle is connected to the tail end of the transparent flexible tube via a tube; the tail needle may be two or more and may be connected to the transparent flexible tube via a T-junction or by direct thermoforming.

[0007] A receiving and fixing plate is provided at the connection between the branch tube and the tail end. The receiving and fixing plate is provided with a groove for accommodating the connection, part of the branch tube and part of the transparent tube. The receiving and fixing plate embeds the connection between the branch tube and the transparent tube into its surface to prevent the connection between the branch tube and the transparent tube from breaking due to external pulling, which could lead to blood collection failure, blood leakage and other situations.

[0008] The device includes a handle rotatably connected to the receiving and fixing plate. The handle is for the operator to hold, and the receiving and fixing plate can rotate relative to the handle to adapt to different blood collection sites and patient positions, improving ease of operation.

[0009] Preferably, the gripping member is plate-shaped with a pin hole; a pin extends from the bottom of the receiving and fixing plate, and the pin passes through the pin hole. The pin extends through the receiving and fixing plate, and the pin cap is located on the bottom surface of the gripping member.

[0010] Preferably, the grip is square, and an arc-shaped groove is provided near the proximal end of the grip close to the tail pin. The grip can be any shape suitable for the operator's hand. The arc-shaped groove facilitates the accommodation of the operator's fingers, and there can be two or three arc-shaped grooves.

[0011] Preferably, there are three tail needles, each connected to the end of the transparent tubing via three branch tubes; the branch tubes and the transparent tubing are fixedly connected by a four-way fitting. Based on clinical experience, having three tail needles better balances cost and blood collection efficiency. The four-way fitting is fitted at the connection point between the branch tubes and the transparent tubing to increase the stability of the connection.

[0012] Preferably, the four-way fitting is embedded in the groove. After the four-way fitting is fitted onto the connection between the branch pipe and the transparent flexible hose, it is then embedded in the groove, further increasing structural stability.

[0013] Preferably, there are three tail needles, each connected to the tail end of the transparent flexible tube via three branch tubes; the branch tubes are integrally formed with the transparent flexible tube, and their connection points are embedded in the grooves.

[0014] Preferably, the venous vacuum blood collection device further includes a hemostatic clamp, which is inserted through the transparent flexible tube to control the opening and closing of the transparent flexible tube.

[0015] Preferably, the gripping member is circular, and the receiving and fixing plate is rotatably connected to the center of the gripping member via the pin.

[0016] Preferably, the gripping member is further provided with a limiting member to limit the rotation angle of the receiving and fixing plate.

[0017] Preferably, the limiting member includes a limiting groove formed on one side of the pin hole and a limiting piece disposed on the pin shaft.

[0018] This invention offers at least the following advantages: The venous vacuum blood collection device of this invention employs a design where one puncture needle connects to multiple tail needles, allowing for the simultaneous collection of multiple blood samples in a single puncture, reducing the risk of infection and minimizing the possibility of infection from multiple punctures. It also avoids the need for multiple changes of blood collection tubes during the blood collection process, improving efficiency and preventing situations such as needle displacement, dislodgement, or even bleeding caused by accidental pulling during tube changes.

[0019] The receiving and fixing plate of this utility model can rotate relative to the holding member. Therefore, medical staff can easily adjust the angle of the tail needle according to the patient's specific condition and operating environment during blood collection, without having to excessively twist the wrist or adjust the body posture, reducing the patient's pain and the difficulty of operation for medical staff, and greatly improving the convenience and comfort of operation.

[0020] This invention embeds the connection between the branch tube and the transparent flexible tube into the groove of the receiving and fixing plate. This reliable connection and stable structure can reduce the accidental risks during blood collection, such as needle detachment or blood leakage. At the same time, reducing operational uncertainties also helps improve the work safety of medical personnel.

[0021] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0027] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0028] like Figures 1-3 As shown, this utility model provides a venous vacuum blood collection device, including a transparent flexible tube 100 and a puncture needle 200 connected to the head end 101 of the transparent flexible tube 100; wherein, it also includes:

[0029] At least one tail needle 300 is connected to the tail end 102 of the transparent flexible tube 100 via a tube 301; the tail needle 300 may be provided in two or more, and may be connected to the transparent flexible tube 100 by means of a T-connector or by direct thermoforming.

[0030] A receiving and fixing plate 400 is disposed at the connection between the branch tube 301 and the tail end 102. The receiving and fixing plate 400 is provided with a groove 401 for accommodating the connection, a portion of the branch tube 301, and a portion of the transparent tubing 100. The receiving and fixing plate 400 embeds the connection between the branch tube 301 and the transparent tubing 100 into its groove, which can stably fix the connection between the branch tube 301 and the transparent tubing 100 on the receiving and fixing plate 400, and prevent the branch tube 301 and the tail end 102 of the transparent tubing 100 from shifting or breaking under pulling. This ensures good sealing and stability of the venous vacuum blood collection device of this utility model, greatly reduces the chance of bacterial contamination, and protects the health of patients and medical staff.

[0031] The device includes a handle 500, which is rotatably connected to the receiving and fixing plate 400. When using the device, the operator holds the handle 500 in their palm and presses their thumb against the receiving and fixing plate 400. They can moderately rotate the receiving and fixing plate 400 to adjust the angle of the tail needle 300 according to the actual blood collection site and patient position, thus adapting to different blood collection sites and patient positions and improving operational convenience. Medical personnel can easily adjust the angle of the tail needle 300 without excessive wrist twisting or body posture adjustments, greatly improving operational convenience and comfort. For example, when drawing blood from a patient with difficulty bending their arm, the tail needle 300 can be flexibly rotated to find the most suitable puncture angle, reducing patient pain and operational difficulty for medical personnel.

[0032] In one embodiment, such as Figure 1 and Figure 4 As shown, the holding member 500 is plate-shaped with a pin hole 501. A pin 402 extends from the bottom of the receiving and fixing plate 400, passing through the pin hole 501. The pin 402 extends through the receiving and fixing plate 400, and the pin cap 403 is located on the bottom surface of the holding member 500. Thus, the operator can use their thumb to rotate the receiving and fixing plate 400, adjusting the angle of the multiple tail needles. Alternatively, the receiving and fixing plate 400 can be selected by rotating the pin cap 403 with other fingers to adjust the tail needle angle. This allows for flexible rotation of the tail needle to find the most suitable puncture angle, improving blood collection efficiency and patient comfort.

[0033] In one embodiment, such as Figure 2As shown, the grip 500 is square, and an arc-shaped groove 502 is provided on the proximal end of the grip 500 near the tail needle 300. For example, there are two arc-shaped grooves 502, which facilitate the fixation of the operator's middle and ring fingers within the grooves, increasing hand stability and preventing accidental dislodgement during blood collection, thus avoiding blood collection failure and injury to the patient.

[0034] In one embodiment, such as Figures 1-3 As shown, there are three tail needles 300, each connected to the tail end 102 of the transparent tubing 100 via three branch tubes 301; the branch tubes 301 and the transparent tubing 100 are fixedly connected by a four-way fitting 103. Based on clinical experience, using three tail needles 300 better balances cost and blood collection efficiency. The four-way fitting 103 is fitted at the connection between the branch tubes 301 and the transparent tubing 100 to increase the stability of the connection. The branch tubes 301 and the transparent tubing 100, for example, have the same diameter and thickness and are made of the same material. This ensures that the tubing of this invention remains sealed, improving the safety of blood collection.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the four-way fitting 103 is embedded in the groove 401. After the four-way fitting 103 is fitted onto the connection between the branch tube 301 and the transparent flexible tube 100, it is embedded in the groove 401, further increasing structural stability. This reduces the shaking of the blood collection needle during use and lowers the risk of injury to the patient. The groove 401 has, for example, a shape that matches the tube at the connection point, such as an umbrella shape. This allows the branch tube 301 and part of the transparent flexible tube 100 to be fixed in the groove at certain intervals, reducing the risk of kinking and making the connection between the branch tube 301 and the tail needle 300 smoother, reducing the occurrence of kinking and ensuring smooth blood flow. The receiving and fixing plate 400 can more stably fix the tail needle to the transparent flexible tube 100, reducing the shaking of the blood collection needle during use and lowering the risk of injury to the patient.

[0036] In one embodiment, such as Figure 1 As shown, there are three tail needles 300, each connected to the tail end 102 of the transparent flexible tube 100 via three branch tubes 301. The branch tubes 301 and the transparent flexible tube 100 are integrally formed, and their connections are embedded in the grooves 401. The integrally formed tubing can reduce processing costs, while improving the stability of the tubing's sealing performance and increasing the blood collection success rate.

[0037] In one embodiment, such as Figure 1As shown, the venous vacuum blood collection device further includes a hemostatic clamp 600, which is inserted through the transparent tubing 100 to control the opening and closing of the transparent tubing 100. The hemostatic clamp 600 is used to control the opening and closing of the transparent tubing 100, and is used to clamp the transparent tubing 100 in time in case of an accident during blood collection to prevent the patient from spurting blood.

[0038] In one embodiment, such as Figure 3 As shown, the gripper 500 is circular, and the receiving and fixing plate 400 is rotatably connected to the center of the gripper 500 via the pin 402. Making the gripper 500 circular makes it easier for the operator to rotate the receiving and fixing plate 400 and increases the convenience of adjusting the angle of the tail needle 300.

[0039] In one embodiment, such as Figure 4 As shown, the holding member 500 is also provided with a limiting member to restrict the rotation angle of the receiving and fixing plate 400. The limiting member includes a limiting groove 502 formed on one side of the pin hole 501 and a limiting piece 404 disposed on the pin 402. The limiting piece 404 reciprocates within the limiting groove 502, thereby limiting the rotation angle of the receiving and fixing plate 400. This reduces the pulling on the patient's skin and blood vessels, reducing patient discomfort. At the same time, stable puncture also reduces pain and local damage caused by the shaking of the tail needle 300.

[0040] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
