DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] refer to Figures 1 to 7 As shown, this embodiment provides a blood sample collection and packaging device, including a housing 1, a sealed connecting tube 2 and at least three partitions 3.

[0038] The shell may be transparent, for example, so that the sample volume and liquid level in each blood sampling cavity 41 can be easily observed during blood sampling.

[0039] Specifically, the housing 1 has a vacuum chamber, and at least three partitions 3 are arranged in the vacuum chamber at intervals, so as to divide the vacuum chamber into at least two blood collection chambers 41 and at least one liquid storage chamber 42 arranged in sequence. Among them, the at least two blood collection chambers 41 and the at least one liquid storage chamber 42 can be arranged in sequence along the length direction of the housing 1, and the liquid storage chamber 42 is located at the outermost side.

[0040] For example, reference Figures 1 to 3 As shown, the shell 1 is arranged along its length direction (reference Figure 2 Eight partitions 3 are arranged at intervals in the X direction (in the vacuum chamber), and the eight partitions 3 divide the vacuum chamber into eight blood collection chambers 41 and a liquid storage chamber 42, and the liquid storage chamber 42 is located at the outermost side.

[0041] refer to Figures 1 to 6 As shown, one side of each blood collection cavity 41 is connected to an injection needle 5, and each injection needle 5 is in communication with the corresponding blood collection cavity 41 and is used to connect with the blood collection tube 11. Each injection needle 5 is fixed to the housing 1, and one end of each injection needle 5 facing the housing 1 extends into the corresponding blood collection cavity 41 to communicate with the corresponding blood collection cavity 41, and one end of each injection needle 5 facing away from the housing 1 can be exposed outside the housing 1, for example, to facilitate connection with the blood collection tube 11.

[0042] It should be noted that when the injection needle 5 is not connected to the blood collection tube 11, the side of each injection needle 5 facing away from the housing 1 is in a sealed state. When the blood collection tube 11 is connected to the injection needle 5, the blood collection tube 11 can release the seal at the end of the injection needle 5, so that the blood collection tube 11 is connected to the corresponding blood collection chamber 41 through the needle cavity of the injection needle 5.

[0043] The blood collection tube 11 may be, for example, a micro-blood collection tube.

[0044] In specific implementation, the connecting tube 2 is arranged on the housing 1 and communicated with one of the blood collection chambers 41. The connecting tube 2 is used to communicate with the blood collection needle 10 for collecting blood samples. The side of the liquid storage chamber 42 away from the injection needle 5 is detachably connected with a sealing member 6. The sealing member 6 can be, for example, a sealing cover, which is detachably connected to the cavity wall of the liquid storage chamber. Of course, the sealing member 6 can also be a sealed sealing film, such as an aluminum composite film.

[0045] For example, reference Figures 1 to 6As shown, the connecting tube 2 is arranged on the top of the housing 1. When in use, the needle of the blood collection needle 10 is inserted into the venous blood vessel of the subject, and the test tube end of the blood collection needle 10 is connected with the connecting tube 2. Under the action of negative pressure, the venous blood can enter the blood collection cavity 41 connected with the connecting tube 2 through the blood collection needle 10 and the connecting tube 2 in sequence.

[0046] refer to Figure 2 and Figure 3 As shown, a flow groove 31 is provided on the side of each partition 3 facing away from the injection needle 5, and two adjacent blood collection chambers 41 are connected through the corresponding flow groove 31, and the liquid storage chamber 42 is connected with the adjacent blood collection chamber 41 through the corresponding flow groove 31, and the height of the flow groove 31 on the partition 3 close to the liquid storage chamber 42 is not lower than the height of the flow groove 31 on other partitions 3, so that the blood sample enters the liquid storage chamber 42 when the liquid level in all blood collection chambers 41 reaches a preset height; the blood sample in each blood collection chamber 41 enters the corresponding blood collection tube 11 through the corresponding injection needle 5 when all injection needles 5 move to the bottom and the seal 6 is opened.

[0047] The preset height of the highest liquid level of the blood sample in the blood sampling cavity 41 is the height at which the flow channel 31 of the liquid storage cavity 42 is located.

[0048] In a specific implementation, the heights of the flow slots of each blood sampling cavity can be the same, for example, so that the volumes of blood samples to be collected by each blood sampling cavity are the same.

[0049] In some implementations, for example, the distance between two adjacent partitions can be changed to adjust the inner size of the corresponding blood sampling cavity to adjust the volume of the blood sample corresponding to the blood sampling cavity. In other implementations, for example, the inner size of the blood sampling cavity can be adjusted by changing the inclination angle of the partition or the thickness of the bottom wall of the blood sampling cavity.

[0050] When used specifically, when the blood collection cavity 41 (reference Figure 2 In the figure, when the liquid level of the blood sample in the fifth blood collection cavity 41 from left to right reaches a preset height, the blood sample can enter the adjacent blood collection cavity 41 through the circulation groove 31, and circulate in sequence until the liquid levels in all blood collection cavities 41 reach the preset height. The blood sample begins to enter the liquid storage cavity 42 from the circulation groove 31 on the partition 3 close to the liquid storage cavity 42. When the blood sample begins to flow into the liquid storage cavity 42, it indicates that the amount of blood sample to be collected has been collected enough. At this time, the blood collection needle 10 can be pulled out from the vein of the subject, which to a certain extent avoids the waste of blood samples caused by excessive collection and the increase in the amount of medical waste generated. At the same time, it also reduces the psychological burden of the subject to a certain extent.

[0051] When the blood sample begins to flow into the liquid storage chamber 42, the blood collection needle 10 is pulled out from the vein of the subject. Then the housing 1 is rotated toward the side where the injection needle 5 is located (refer to Figure 6 As shown, the housing 1 is rotated counterclockwise) so that all injection needles 5 are located below the housing 1 (reference Figure 7 As shown). Then, each injection needle 5 is connected to a blood sampling tube 11. At this time, each blood sampling tube 11 is connected to the corresponding blood sampling cavity 41 through the corresponding injection needle 5. Finally, the seal 6 is opened, and the blood sample in each blood sampling cavity 41 can enter the corresponding blood sampling tube 11 through the corresponding injection needle 5, thereby realizing the simultaneous collection of multiple blood samples from the same person being collected. Compared with the solution in the prior art that requires medical staff to constantly replace the blood sampling tube 11, the blood sample collection process is simplified, the collection process is simple, the blood sample collection time is shortened to a certain extent, the work efficiency is improved, and at the same time, the phenomenon of biological contamination caused by the uncontrolled replacement of the blood sampling tube 11 is avoided, thereby improving the safety of blood sample collection.

[0052] At the same time, by providing the liquid storage chamber 42, when the blood sample starts to flow into the liquid storage chamber 42, it indicates that the amount of blood sample that needs to be collected has been collected enough, so that a prompt signal to stop blood collection can be given to the medical staff who collects the blood sample. In other words, the medical staff can know whether to stop blood collection by observing whether there is a blood sample in the liquid storage chamber 42. This is convenient to use and improves the utilization rate of blood samples.

[0053] It should be noted that the blood sample collection and packaging device of this embodiment is a disposable product and meets the relevant requirements of medical and health care.

[0054] The blood sample collection and packaging device provided in this embodiment is provided with a shell 1, a sealed connecting tube 2 and at least three partitions 3. The shell 1 has a vacuum chamber, and at least three partitions 3 are arranged in the vacuum chamber at intervals to divide the vacuum chamber into at least two blood collection chambers 41 arranged in sequence and at least one liquid storage chamber 42, and the liquid storage chamber 42 is located at the outermost side. An injection needle 5 is connected to one side of each blood collection chamber 41, and each injection needle 5 is connected to the corresponding blood collection chamber 41 and is used to connect to the blood collection tube 11; the connecting tube 2 is provided on the shell 1 and is connected to one of the blood collection chambers 41, and the connecting tube 2 is used to communicate with the blood collection needle 10 for collecting blood samples; the side of the liquid storage chamber 42 away from the injection needle 5 is detachably connected with a seal 6. A flow slot 31 is provided on the side of each partition 3 away from the injection needle 5. Two adjacent blood collection chambers 41 are connected through the corresponding flow slot 31. The liquid storage chamber 42 is connected with the adjacent blood collection chamber 41 through the corresponding flow slot 31. The height of the flow slot 31 on the partition 3 close to the liquid storage chamber 42 is greater than the height of the flow slot 31 on other partitions 3, so that the blood sample enters the liquid storage chamber 42 when the liquid level in all blood collection chambers 41 reaches a preset height; the blood sample in each blood collection chamber 41 enters the corresponding blood collection tube 11 through the corresponding injection needle 5 when all injection needles 5 move to the bottom and the seal 6 is opened. When in use, the needle of the blood collection needle 10 is inserted into the vein of the person being collected, and the test tube end of the blood collection needle 10 is connected to the connecting tube 2. At this time, under the action of negative pressure, the blood enters the blood collection chamber 41 connected to the connecting tube 2 through the blood collection needle 10 and the connecting tube 2 in sequence. Since two adjacent blood collection chambers 41 are connected through corresponding circulation grooves 31, when the liquid level of the blood sample in the blood collection chamber 41 connected to the connecting tube 2 reaches a preset height, the blood sample enters an adjacent blood collection chamber 41 through the circulation groove 31 until the liquid levels in all blood collection chambers 41 reach the preset height. Since the height of the circulation groove 31 on the partition 3 close to the liquid storage chamber 42 is greater than the height of the circulation grooves 31 on other partitions 3, when the liquid levels in all blood collection chambers 41 reach the preset height, excess blood samples begin to enter the circulation grooves 31. At this time, the shell 1 is rotated to make the injection needle 5 located below the shell 1. While ensuring that each injection needle 5 is connected to a blood collection tube 11, the seal 6 is opened. At this time, the blood sample in each blood collection cavity 41 can enter the corresponding blood collection tube 11 through the corresponding injection needle 5 under the action of atmospheric pressure and gravity, thereby realizing the simultaneous collection of multiple blood samples from the same person being collected. Compared with the solution in the prior art that requires medical staff to constantly replace the blood collection tube 11, the blood sample collection process is simplified, the collection process is simple, the blood sample collection time is shortened to a certain extent, the work efficiency is improved, and at the same time, the occurrence of biological contamination caused by the unrequited replacement of the blood collection tube 11 is avoided, thereby improving the safety of blood sample collection.

[0055] In some embodiments, reference Figures 2 to 4 As shown, along the direction from the circulation slot 31 to the injection needle 5, the thickness of each partition 3 increases successively, so that each blood collection cavity 41 is formed into a conical cavity. This arrangement makes the inner cavity of each blood collection cavity 41 facing the injection needle 5 smaller, and the inner cavity of each blood collection cavity 41 facing the circulation slot 31 larger. After the housing 1 is rotated until the injection needle 5 is located below the housing 1, the blood sample in each blood collection cavity 41 flows into the corresponding blood collection tube 11 more quickly, further shortening the blood sample collection time and improving work efficiency. It is particularly suitable for collecting trace blood, such as fingertip blood and earlobe blood.

[0056] The partition 3 may be, for example, a wedge-shaped or trapezoidal structure.

[0057] Definition: The arrangement direction of the blood sampling cavity 41 is the length direction of the housing 1 (refer to Figure 2 The X direction in the figure), the vertical direction perpendicular to the arrangement direction of the blood sampling chamber 41 is the height direction of the housing 1 (reference Figure 2 The horizontal direction perpendicular to the arrangement direction of the blood collection chamber 41 (i.e., the direction from the flow slot 31 to the injection needle 5) is the width direction of the housing 1 (reference Figure 2 in the Y direction).

[0058] In some embodiments, reference Figure 5 and Figure 6 As shown, in the direction from the circulation slot 31 to the injection needle 5, at least a portion of the top wall 411 of each blood sampling cavity 41 is tilted inwardly, and / or at least a portion of the bottom wall 412 of each blood sampling cavity 41 is tilted inwardly.

[0059] That is to say, the side of the top wall 411 of the blood collection chamber 41 close to the injection needle 5 is tilted downward, and the side of the bottom wall 412 of the blood collection chamber 41 close to the injection needle 5 is tilted upward, so that the side of each blood collection chamber 41 close to the injection needle 5 is formed into a constriction, which further facilitates the blood sample to flow into the corresponding blood collection tube 11 more quickly, thereby further shortening the blood sample collection time and improving work efficiency.

[0060] In some embodiments, reference Figures 1 to 4 As shown, the connecting tube 2 can be connected to the blood collection chamber 41 located in the middle, so that when the liquid level of the blood sample in the blood collection chamber 41 connected to the connecting tube 2 reaches a preset height, the blood sample can flow into the blood collection chambers 41 located on both sides thereof at the same time. When the total amount of blood samples to be collected is the same, the collection time is shortened and work efficiency is improved.

[0061] For example, reference Figure 2As shown, in the direction from left to right, the connecting tube 2 is connected with the fifth blood collection chamber 41. With such a design, when the liquid level in the fifth blood collection chamber 41 reaches a preset height, the blood sample enters the fourth blood collection chamber 41 through the flow slot 31 on the fourth partition 3, and enters the sixth blood collection chamber 41 from the flow slot 31 on the fifth partition 3. When the liquid level in the fourth blood collection chamber 41 reaches a preset height, the blood sample enters the third blood collection chamber 41 from the flow slot 31 on the third partition 3, until the liquid level in the first blood collection chamber 41 reaches a preset height. When the liquid level in the sixth blood collection chamber 41 reaches a preset height, the blood sample enters the seventh blood collection chamber 41 from the flow slot 31 on the sixth partition 3, until the liquid level in the eighth blood collection chamber 41 reaches a preset height. With such a configuration, the blood sample can flow from two directions at the same time, which is beneficial to shortening the collection time and improving work efficiency.

[0062] In some embodiments, the connecting tube 2 includes a hollow tube body 21 and a sealing member 22 sealed at the inlet end of the tube body 21. The tube body 21 is connected to one of the blood collection cavities 41. The blood collection needle 10 is inserted into the sealing member 22 and connected to the inner cavity of the tube body 21. The structure is simple and easy to manufacture, and the blood collection needle 10 is inserted into the connection.

[0063] The sealing member 22 may be, for example, medical rubber.

[0064] In addition, refer to Figures 1 to 6 As shown, the top of the connecting tube 2 can be exposed outside the housing 1, which is convenient for identification and for the insertion and connection of the blood collection needle 10. Of course, the connecting tube 2 can also be arranged inside the housing 1, so that the top of the connecting tube 2 is flush with the outer wall of the housing 1, which is convenient for the stacking and transportation of the blood sample collection and packaging device.

[0065] In some embodiments, reference Figure 2 As shown, the height of the seal 6 is greater than the height of the flow groove 31 on the partition 3 close to the liquid storage chamber 42. In this way, when collecting blood samples, there is a large distance between the blood sample flowing into the liquid storage chamber 42 and the seal 6, and the blood sample will not block or contaminate the seal 6, which is safer to use.

[0066] For specific implementation, refer to Figures 1 to 3 As shown, the seal 6 is arranged on the top of the side of the shell 1 opposite to the injection needle 5, or the seal 6 is arranged on the side of the top surface of the shell 1 away from the injection needle 5, so that when collecting blood samples and packaging blood samples after rotating the shell 1, the blood sample always maintains a large distance from the seal 6, which is safer to use.

[0067] In some embodiments, reference Figure 1As shown, each injection needle 5 includes a sealing cover 51 and a hollow needle body 52. ​​Each needle body 52 is connected to the housing 1 and communicates with the corresponding blood collection cavity 41. Each sealing cover 51 is covered on the end of the corresponding needle body 52 away from the housing 1 and can slide relative to the corresponding needle body 52.

[0068] During specific use, when the blood collection tube 11 is being sheathed on the needle body 52, the blood collection tube 11 pushes the sealing cover 51 toward the direction close to the shell 1, so that the end of the needle body 52 away from the shell 1 is opened, and the blood collection tube 11 is connected with the corresponding blood collection tube 11 through the needle cavity of the needle body 52. ​​The structure is simple and easy to use.

[0069] The sealing cover 51 may be made of medical rubber, medical silicone, etc.

[0070] In some embodiments, the distance between the sealing cover 51 on each needle body 52 and the shell 1 is different. Specifically, the sealing cover 51 on each needle body 52 is arranged at intervals along the width direction of the shell 1. If multiple blood collection tubes 11 are connected together, this arrangement allows the multiple blood collection tubes 11 to contact the corresponding sealing covers 51 in batches during the simultaneous connection process, saving the driving force required for the connection, saving time and effort, and facilitating the connection.

[0071] In some embodiments, reference Figures 1 to 7 As shown, each injection needle 5 is covered with a protective cover 7 on its outer side, and the inner wall of the protective cover 7 and the outer wall of the injection needle 5 enclose a receiving space for the blood collection tube 11 to extend into, and each protective cover 7 is connected to the housing 1.

[0072] By arranging a protective cover 7 on the outside of each injection needle 5, the protective cover 7 protects the injection needle 5. On the one hand, it is convenient for transportation, and on the other hand, it can prevent the injection needle 5 from being bent or damaged, which is very practical.

[0073] In some embodiments, reference Figures 1 to 4 As shown, a shell 81 is provided on the outside of the shell 1. The shell 81 is located at least on the side of the shell 1 facing the injection needle 5. An avoidance hole for the injection needle 5 to pass through is opened on the shell 81. The protective cover 7 is connected to the shell 81 to facilitate the connection of the protective cover 7, which improves the integrity and aesthetics to a certain extent.

[0074] In some embodiments, reference Figure 6 and Figure 7As shown, the top wall 411 of each blood collection cavity 41 is provided with a strip groove 9 that is recessed outward, and each strip groove 9 is connected to the blood collection cavity 41 where it is located, and extends from the side where the injection needle 5 is located toward the side where the circulation groove 31 is located, that is, the strip groove 9 in each blood collection cavity 41 extends along the width direction of the shell 1. Exemplarily, the extension direction of each strip groove 9 is perpendicular to the arrangement direction of the multiple blood collection cavities 41. In this way, when the shell 1 is rotated until the injection needle 5 is located below the shell 1, if the blood sample in the blood collection cavity 41 contains bubbles, the bubbles can enter the strip groove 9 of the blood collection cavity 41, which to a certain extent avoids the phenomenon that the blood sample cannot enter the blood collection tube due to the rapid disappearance of the vacuum in the blood collection tube due to the bubbles entering the blood collection tube 11. It is particularly suitable for micro blood collection tubes with a small inner cavity space, thereby improving the quality of the blood sample entering the blood collection tube 11 and ensuring the effective collection and packaging of the blood sample.

[0075] In some embodiments, reference Figures 5 to 7 As shown, each partition 3 is provided with a bevel 32 on the side facing away from the injection needle 5, the bevel 32 is located at the bottom, and each bevel 32 is inclined in the direction from top to bottom toward the direction close to the blood collection cavity 41, and each flow groove 31 is opened on the bevel 32 of the partition 3. This arrangement can reduce the amount of blood collected while meeting the inspection amount. On the one hand, it can reduce the psychological burden of the person being collected, and on the other hand, it can avoid the increase in the amount of medical waste generated due to excessive collection, and it is highly practical.

[0076] In some embodiments, reference Figures 1 to 6 As shown, a bracket 82 is provided below the shell 1. The bracket 82 can be, for example, a support plate arranged along the height direction of the shell 1. The side of the bracket 82 facing away from the shell 1 is used to be flush with the bottom surface of the shell 1, that is, the bottom surface of the bracket 82 is flush with the bottom surface of the shell 1. In this way, during the blood collection process, the blood sample collection and packaging device can be kept in a horizontal state, the position is stable during the collection process, the blood sample is collected easily, and it is easy to use.

[0077] In other embodiments, the bottom surface of the shell 81 can be set as a horizontal plate, or the bottom surface of the shell 1 can be set as a horizontal plate, which can also keep the blood sample collection and packaging device in a horizontal state during the collection process.

[0078] It should be noted that the blood sample collection and packaging device of this embodiment can be applied to manual operation by medical personnel, and can also be applied to instruments and equipment with blood collection function, such as automatic blood collection instrument.

[0079] Among them, when the blood sample collection and packaging device of this embodiment is used in conjunction with an automatic blood collection instrument, the seal 6 can adjust the air pressure in the blood collection chamber and the liquid storage chamber, such as negative pressure and positive pressure, through a medical air pump.
