Abstract
Description
Technical Field
[0001] This utility model relates to the field of blood collection equipment technology, and in particular to a vacuum blood collection device for polyclonal antibody immune serum. Background Technology
[0002] Polyclonal antibody immune serum plays a crucial role in many fields such as medical research, disease diagnosis, and biopharmaceuticals. As an important tool for obtaining such serum samples, the polyclonal antibody immune serum vacuum blood collection device can accurately and efficiently collect blood, ensuring the smooth progress of subsequent serum separation and analysis. Through a pre-set vacuum environment, it uses the pressure difference inside and outside the blood collection tube to make the blood flow into the blood collection tube automatically, reducing the interference of human factors on the blood collection process, improving the accuracy and stability of blood collection, and helping to collect a sufficient amount of blood samples in a short time to meet various testing needs.
[0003] However, vacuum blood collection for polyclonal antibody immune serum places extremely high demands on the vacuum level of the blood collection tubes. Existing methods for checking for leaks in blood collection tubes mainly rely on visual inspection and simple pressure tests. Visual inspection can often only detect obvious damage or cracks on the surface of the blood collection tube, but it is difficult to detect tiny leaks. Traditional pressure tests require specialized equipment and are relatively cumbersome to operate, and usually cannot be performed on-site. As a result, in practical applications, if a tiny leak in the blood collection tube is not detected in time, it will reduce the vacuum level inside the blood collection tube, affecting the normal collection of blood, leading to problems such as slower blood collection speed, insufficient blood volume, or even blood clotting. In severe cases, the collected blood sample may be contaminated and cannot be used for subsequent polyclonal antibody immune serum preparation and testing, thus delaying the research or diagnostic process, increasing costs, and reducing work efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polyclonal antibody immune serum vacuum blood collection device. This device uses an elastic membrane to visually indicate the vacuum level inside the blood collection tube. When the elastic membrane deforms, it moves the guide rod and the indicator at the bottom of the guide rod together. The indicator bar is equipped with color indicators, and the vacuum level inside the blood collection tube can be viewed by observing the color range on the indicator bar where the indicator is located.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A vacuum blood collection device for polyclonal antibody immune serum includes a blood collection tube, the upper and lower ends of which are not sealed. An end cap is snapped onto the upper end of the blood collection tube. The end cap includes a cap shell, and a rubber stopper is embedded inside the cap shell. The rubber stopper is made of antibacterial elastic material. An airtight self-checking component is snapped onto the lower end of the blood collection tube. The airtight self-checking component includes a transparent sealing shell, and a transparent sealing plug is fitted inside the transparent sealing shell. The transparent sealing plug is tightly fitted to the inner wall of the blood collection tube, and an elastic membrane is fixedly connected to the top of the transparent sealing plug.
[0007] Through the above technical solution, this vacuum blood collection device, as a blood collection container, allows for direct observation of whether there is leakage or contamination inside the blood collection tube. During the vacuuming stage, the port of the vacuuming equipment is inserted into the blood collection tube through the plug, and then the vacuuming operation is performed. During the vacuuming process, because the upper end of the elastic membrane is in contact with the inner cavity of the blood collection tube, and the lower part of the elastic membrane is in contact with the atmosphere, the middle part of the elastic membrane begins to deform upward under the action of the negative pressure difference between the two. If leakage occurs at any point in the blood collection tube, the vacuum environment of the blood collection tube will be destroyed or contaminated, and the negative pressure difference acting on the elastic membrane will decrease, thereby causing the elastic membrane to recover. Before performing vacuum blood collection of polyclonal antibody immune serum, the staff can directly observe the degree of deformation of the elastic membrane to see whether there is leakage inside the blood collection tube.
[0008] Furthermore, the elastic membrane is made of an elastic material and its surface is coated with an anticoagulant;
[0009] The above technical solution prevents the collected blood samples from coagulating at the bottom of the test tube.
[0010] Furthermore, a guide rod is fixedly connected directly below the elastic membrane cloth, an indicator is fixedly connected to the bottom of the guide rod, a glass guide tube is fixedly connected to the bottom center of the transparent sealing shell, an indicator strip is provided on the inner side wall of the glass guide tube, and both the guide rod and the indicator are located inside the glass guide tube.
[0011] With the above technical solution, when the elastic membrane deforms, it will cause the guide rod and the indicator at the bottom of the guide rod to move together. The indicator bar is equipped with color indicators. By observing the color range on the indicator bar where the indicator is located, the vacuum level in the blood collection tube can be checked.
[0012] Furthermore, multiple color indicator marks are provided on the surface of the glass guide tube;
[0013] The above technical solution allows for a direct visual representation of the vacuum level in the blood collection tube based on the position of the indicator.
[0014] Furthermore, a light-proof placement component is installed on the outer wall of the transparent sealing shell. The light-proof placement component includes a fixing component, and a sliding sleeve is slidably connected to the upper limit of the outer wall of the fixing component.
[0015] The above technical solution can shield the blood collection tube and the airtight self-checking device by using a sliding cover, preventing the light source from shining directly on the blood sample and preventing the outer surface of the sliding cover from being variable, so that the test tube is not easy to roll off when placed on the table.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, if any part of the blood collection tube leaks, the vacuum environment of the blood collection tube will be destroyed or contaminated, and the negative pressure difference acting on the elastic membrane will decrease, which will lead to the elastic membrane recovering. Before performing vacuum blood collection of polyclonal antibody immune serum, the staff can visually check whether there is a leak in the blood collection tube by observing the degree of deformation of the elastic membrane.
[0018] 2. In this utility model, when the elastic membrane deforms, it will cause the guide rod and the indicator at the bottom of the guide rod to move together. The indicator strip is equipped with color indicator marks. By observing the color range on the indicator strip where the indicator is located, the vacuum level in the blood collection tube can be checked.
[0019] 3. In this utility model, the sliding cover can shield the blood collection tube and the airtight self-checking component, preventing the light source from shining directly on the blood sample and preventing the outer surface of the sliding cover from being variable, so that the test tube is not easy to roll off when placed on the table.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example: Refer to Figure 1-4 This utility model provides an embodiment of a polyclonal antibody immune serum vacuum blood collection device, including a blood collection tube 1. The upper and lower ends of the blood collection tube 1 are not sealed. An end cap 2 is snapped onto the upper end of the blood collection tube 1. The end cap 2 includes a cover shell 21. A rubber stopper 22 is embedded inside the cover shell 21. The rubber stopper 22 is made of antibacterial elastic material. An airtight self-checking component 4 is snapped onto the lower end of the blood collection tube 1. The airtight self-checking component 4 includes a transparent sealing shell 41. A transparent sealing plug 42 is fitted inside the transparent sealing shell 41. The transparent sealing plug 42 is tightly fitted to the inner wall of the blood collection tube 1. An elastic membrane 45 is fixedly connected to the top of the transparent sealing plug 42. This vacuum blood collection device, serving as a blood collection container, allows for direct visualization of any leaks or contamination inside the blood collection tube. During the vacuuming phase, the port of the vacuuming device is inserted into the blood collection tube 1 through the stopper 22, followed by vacuuming. During this process, the upper end of the elastic membrane 45 contacts the inner cavity of the blood collection tube 1, while the lower part of the elastic membrane 45 contacts the atmosphere. Under the influence of the negative pressure difference, the middle portion of the elastic membrane 45 begins to deform upwards. If a leak occurs at any point in the blood collection tube, the vacuum environment of the blood collection tube 1 is disrupted or contaminated, reducing the negative pressure difference acting on the elastic membrane 45, causing it to recover. Before performing vacuum blood collection with polyclonal antibody immune serum, staff can visually check for leaks inside the blood collection tube 1 by observing the degree of deformation of the elastic membrane 45. The elastic membrane 45 is made of elastic material and coated with an anticoagulant to prevent the collected blood sample from coagulating at the bottom of the test tube.
[0032] In an optional embodiment: a guide rod 46 is fixedly connected to the bottom of the elastic diaphragm 45, and an indicator 47 is fixedly connected to the bottom of the guide rod 46. A glass guide tube 43 is fixedly connected to the center of the bottom of the transparent sealing shell 41, and an indicator strip 44 is provided on the inner side wall of the glass guide tube 43. Both the guide rod 46 and the indicator 47 are located inside the glass guide tube 43. When the elastic diaphragm 45 deforms, it will cause the guide rod 46 and the indicator 47 at the bottom of the guide rod 46 to move together. The indicator strip 44 is provided with color indicators. By observing the color range on the indicator strip 44 where the indicator 47 is located, the vacuum level in the blood collection tube 1 can be checked.
[0033] In an optional embodiment, multiple color indicators are provided on the surface of the glass guide tube 43. The position of the indicator 47 can visually indicate the vacuum level in the blood collection tube 1.
[0034] In an optional embodiment: a light-proof placement component 3 is installed on the outer wall of the transparent sealing shell 41. The light-proof placement component 3 includes a fixing component 31. A sliding sleeve 32 is slidably connected to the upper limit of the outer wall of the fixing component 31. The sliding sleeve 32 can block the blood collection tube 1 and the airtight self-checking component 4, preventing the light source from shining directly on the blood sample, and preventing the outer surface of the sliding sleeve 32 from being variable, so that the test tube is not easy to roll off when placed on the table.
[0035] Working Principle: This vacuum blood collection device, acting as a blood collection container, allows for direct visualization of any leaks or contamination inside the blood collection tube. During the vacuuming phase, the port of the vacuuming equipment is inserted into the blood collection tube 1 through the stopper 22, followed by vacuuming. During this process, the upper end of the elastic diaphragm 45 is in contact with the inner cavity of the blood collection tube 1, while the lower part of the elastic diaphragm 45 is in contact with the atmosphere. Therefore, under the influence of the negative pressure difference, the middle portion of the elastic diaphragm 45 begins to deform upwards. If a leak occurs at any point in the blood collection tube, the vacuum environment of the blood collection tube 1 is disrupted or contaminated, reducing the negative pressure difference acting on the elastic diaphragm 45, which in turn causes the elastic diaphragm 45 to recover. Before performing vacuum blood collection of polyclonal antibody immune serum, staff can visually check for leaks in the blood collection tube 1 by observing the degree of deformation of the elastic membrane 45. When the elastic membrane 45 deforms, it will cause the guide rod 46 and the indicator 47 at the bottom of the guide rod 46 to move together. The indicator strip 44 is equipped with color indicators. By observing the color range on the indicator strip 44 where the indicator 47 is located, the vacuum level in the blood collection tube 1 can be checked. The sliding cover 32 can shield the blood collection tube 1 and the airtight self-checking component 4 to prevent the light source from shining directly on the blood sample. The outer surface of the sliding cover 32 is also flexible, making it less likely for the test tube to roll off when placed on the table.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
