Description

Technical Field

[0001] The utility model relates to the technical field of blood detection auxiliary instruments, in particular to an anticoagulant blood sample clot catcher. Background Art

[0002] Anticoagulant blood specimens refer to blood samples obtained by drawing blood from patients into blood collection tubes and adding corresponding anticoagulants. Although adding anticoagulants can effectively prevent the blood in the blood collection tubes from clotting, in practice, there are cases where the anticoagulant and blood are mixed unevenly, causing some blood to clot. Once blood in the blood collection tubes clot, it will affect the accuracy of the final test results. Therefore, when the existing hospital laboratory department conducts laboratory tests on the blood in the anticoagulant blood collection tubes, it is necessary to determine whether there are clots in the blood before and after the test.

[0003] It is understood that the existing hospital laboratory does not have a dedicated instrument for detecting whether there are clots in the blood in the anticoagulant blood collection tube. Usually, the test personnel will turn the blood collection tube upside down to mix it and observe it with the naked eye. However, if there are tiny clots that cannot be observed with the naked eye, the blood test can only be completed first. When the test results are inconsistent with the clinical situation or the deviation is large, a sterile rod (such as a sterile medical cotton swab rod) is generally inserted into the blood collection tube for stirring to determine whether there are clots in the blood in the blood collection tube. However, due to the poor transparency of blood and the fact that the sterile rod is usually short and smooth, it is difficult to reach the bottom of the blood collection tube and hang on the wall. Therefore, it is often difficult to accurately determine whether there are clots in the blood by stirring, and it may result in erroneous test results after the blood with clots is tested. Summary of the invention

[0004] The utility model aims to provide an anticoagulant blood sample clot catcher, so as to at least overcome the technical problem that the existing hospital laboratory does not have a dedicated device for detecting whether the blood in the blood collection tube has clots, and thus cannot more accurately determine whether there are clots in the blood.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0007] In some possible embodiments, the bottom of the capturing portion is in an arc-shaped structure, and the connection position between the holding portion and the capturing portion is located on the outer wall of the capturing portion.

[0008] In some possible embodiments, the holding portion is arranged to be inclined relative to the capturing portion.

[0009] In some possible embodiments, the angle between the holding portion and the capturing portion is 120-150°.

[0010] In some possible embodiments, the length of the grip portion is adjustable.

[0011] In some possible embodiments, the gripping portion includes a fixed tube and an adjusting rod, and the fixed tube and the adjusting rod are coaxially arranged;

[0012] One end of the adjusting rod is connected to the capturing portion, and the other end of the adjusting rod extends into the interior of the fixing tube. The outer wall of the adjusting rod is provided with an external thread along its axial direction, and the adjusting rod is threadedly connected to the fixing tube.

[0013] In some possible embodiments, a connecting portion is provided on an outer wall of the capturing portion, and a threaded hole adapted to the external thread of the adjusting rod is opened in the connecting portion.

[0023] Please refer to Figures 1 to 3 This embodiment provides an anticoagulant blood specimen clot catcher to at least overcome the technical problem that the existing hospital laboratory does not have a dedicated device for detecting whether there are clots in the blood in the blood collection tube, and thus cannot more accurately determine whether there are clots in the blood.

[0024] Specifically, the clot catcher includes a holding portion 10 and a capturing portion 20, wherein the holding portion 10 is used for the inspector to hold, and the capturing portion 20 is used to capture clots that may exist in the blood in the blood collection tube, thereby assisting the inspector to determine whether there are clots in the blood in the blood collection tube, and ensuring as much as possible that no clots appear in the blood used for laboratory testing.

[0025] In this embodiment, combined with Figure 1 As shown in the figure, the capturing part 20 is arranged at one end of the holding part 10. At this time, in order to capture the clots that may exist in the blood, Figure 2 As shown, the capture portion 20 is provided with a capture cavity 20a having an opening, and the opening of the capture cavity 20a faces upward. At the same time, the outer wall of the capture portion 20 is provided with a plurality of leakage holes 20b communicating with the capture cavity 20a.

[0026] It is understandable that the capture part 20 after the above arrangement is roughly similar to an existing colander. In actual implementation, the outer diameter of the capture part 20 should be smaller than the inner diameter of the blood collection tube so that the capture part 20 can normally enter the blood collection tube and immerse into the blood in the blood collection tube. At the same time, the size and number of the leakage holes 20b provided on the capture part 20 can be set according to actual needs, as long as the clot can be prevented from entering the capture cavity 20a and then leaking out from the leakage holes 20b.

[0027] For example, blood collection tubes used in existing hospitals generally have two specifications. The size parameters of the first specification of blood collection tubes are: diameter 1.3cm, length 7.5cm; the size parameters of the second specification of blood collection tubes are: diameter 1.3cm, length 10cm. And it is known that clots that may exist in the blood are generally larger than 2mm. On this basis, the diameter of the capture part 20 can be set to 0.8-1cm, the diameter of the holding part 10 can be set to 0.5cm, the total length of the holding part 10 and the capture part 20 can be set to 12cm, and the diameter of the leakage hole 20b can be set to 1-2mm, so that the holding part 10 can drive the capture part 20 to extend into the blood collection tube, and can achieve the capture of clots that may exist in the blood.

[0028] In actual use, the inspector holds the holding portion 10 and slowly extends the capturing portion 20 into the blood in the blood collection tube, and makes the capturing portion 20 completely immersed in the blood. After the capturing portion 20 extends to the inner bottom of the blood collection tube, the inspector uses the capturing portion 20 to scoop out the blood in the blood collection tube until the capturing portion 20 is removed from the blood. In this process, the blood in the capturing chamber 20a of the capturing portion 20 will flow back into the blood collection tube from the leakage hole 20b. At this time, if there is a clot in the blood in the capturing chamber 20a, the clot cannot fall into the blood collection tube through the leakage hole 20b but remains in the capturing chamber 20a. In this way, the inspector can be assisted in judging whether there is a clot in the blood in the blood collection tube, and in actual application, the above method should be repeatedly used to capture the clot that may exist in the blood, thereby improving the accuracy of the final judgment of whether there is a clot in the blood.

[0029] On this basis, combined with the foregoing, considering that the diameter of a general blood collection tube is not large and the clot is usually located at the inner bottom of the blood collection tube, in order to facilitate the capture portion 20 to be able to more smoothly extend into the blood collection tube and reach the inner bottom of the blood collection tube, this embodiment further improves the structure of the capture portion 20 and the connection method between the capture portion 20 and the holding portion 10.

[0030] Specifically, combined Figure 1 or Figure 2 As shown in the content, the bottom of the capturing portion 20 in this embodiment is an arc-shaped structure. For example, the capturing portion 20 is roughly a bowl-shaped structure. By setting the bottom of the capturing portion 20 to an arc-shaped structure, the capturing portion 20 can hold more blood at a time, which is beneficial for the capturing portion 20 to extend into the inner bottom of the arc-shaped structure of the blood collection tube to capture clots that may exist in the blood.

[0031] At the same time, Figure 1As shown, the connection position between the gripping portion 10 and the capturing portion 20 is located on the outer wall of the capturing portion 20, that is, the gripping portion 10 is connected to the outer wall of the capturing cavity 20a, and as preferably, the gripping portion 10 is inclined relative to the capturing portion 20, wherein, as Figure 3 As shown, the angle α between the holding portion 10 and the capturing portion 2 is an obtuse angle. Furthermore, the angle α is preferably set to 120-150°, so that when in use, it is convenient to adjust the posture of the capturing portion 20 when it is extended into the blood collection tube, which is more conducive to the capturing portion 20 to capture clots that may exist in the blood.

[0032] With such arrangement, in actual use, the inspector holds the holding portion 10 and then extends the capturing portion 20 into the inner bottom of the blood collection tube to capture any clots that may exist in the bottom of the blood collection tube. On this basis, by appropriately adjusting the posture of the capturing portion 20 when entering the blood collection tube and repeatedly using the capturing portion 20 to capture any clots that may exist in the blood collection tube, it is possible to effectively determine whether there are clots in the blood in the blood collection tube, thereby improving the accuracy of determining whether there are clots in the blood collection tube.

[0033] On the other hand, considering that the models of blood collection tubes used in the laboratory departments of general hospitals are different, and the lengths of blood collection tubes of different models are often different, in order to further improve the practicality of the clot catcher so that the clot catcher can be used with blood collection tubes of various lengths, the present embodiment provides the holding portion 10 as a length-adjustable structure. For example, the existing conventional telescopic rod can be directly used as the holding portion 10, which is conducive to adjusting the length of the holding portion 10 according to the length of the blood collection tube, ensuring that the capturing portion 20 can extend to the inner bottom of the blood collection tube, so that the capturing portion 20 can contact the blood in all areas of the blood collection tube.

[0034] In order to achieve the adjustable length of the gripping portion 10 and further optimize the use effect of the clot catcher, this embodiment uses another rod with adjustable length as the gripping portion 10. Figure 1 As shown in the content, the holding portion 10 of the present embodiment includes a fixed cylinder 11 and an adjusting rod 12, wherein the fixed cylinder 11 and the adjusting rod 12 are coaxially arranged, that is, the axes of the fixed cylinder 11 and the adjusting rod 12 coincide, at this time, one end of the adjusting rod 12 is connected to the capturing portion 20, and the other end of the adjusting rod 12 extends into the interior of the fixed cylinder 11, and the outer wall of the adjusting rod 12 is provided with an external thread 12a along its axial direction, and at the same time, a threaded hole adapted to the external thread 12a of the adjusting rod 12 is provided at one end of the fixed cylinder 11 close to the adjusting rod 12, so that when the adjusting rod 12 extends into the interior of the fixed cylinder 11, the connection between the adjusting rod 12 and the fixed cylinder 11 is a threaded connection.

[0035] It is understandable that in actual implementation, anti-slip grooves 11a can also be set on the outer wall of the end of the fixed tube 11 away from the capture portion 20 to increase the friction between the outer wall of the fixed tube 11 when the inspector holds the fixed tube 11, thereby preventing the grip portion 10 from easily slipping out of the inspector's hand.

[0036] With such a configuration, in actual use, the length of the adjusting rod 12 exposed outside the fixing tube 11 can be changed by appropriately twisting the fixing tube 11 or the adjusting rod 12 according to the length of the blood collection tube, thereby adjusting the length of the gripping portion 10, which is simple and convenient to operate. It is worth noting that in this embodiment, the length of the gripping portion 10 is adjustable by providing an external thread 12a on the outer wall of the adjusting rod 12. On the one hand, it is simple and convenient to adjust the length of the gripping portion 10 in this manner, and on the other hand, a groove (i.e., a thread groove) can be formed on the outer wall of the adjusting rod 12. When the adjusting rod 12 enters the blood collection tube together with the capturing portion 20, the contact area between the adjusting rod 12 and the blood in the blood collection tube can be increased, which is conducive to the adhesion of possible clots in the blood to the thread groove on the outer wall of the adjusting rod 12, thereby further improving the accuracy of judging whether there are clots in the blood.

[0037] On this basis, combined with Figure 1 and Figure 2 As shown in the content, in actual implementation, a connecting portion 30 for connecting with the holding portion 10 can be provided on the outer wall of the capturing portion 20, and the connecting portion 30 is provided with a threaded hole adapted to the external thread 12a of the adjusting rod 12, that is, the adjusting rod 12 and the connecting portion 30 can also be threadedly connected, so that the capturing portion 20 is also a detachable structure relative to the holding portion 10. By setting the capturing portion 20 as a detachable structure, on the one hand, it is beneficial to disassemble and package the various components during production and packaging, thereby further reducing the volume of the clot catcher in an unused state, and on the other hand, it is possible to use capturing portions 20 with a variety of different outer diameters, thereby facilitating the selection of capturing portions 20 with different outer diameters for use according to the different inner diameters of the blood collection tube. The selection criterion is to ensure that the capturing portion 20 can smoothly enter the blood collection tube so that the capturing portion 20 can hold as much blood as possible at a time, thereby reducing the number of repeated captures of clots in the blood and improving efficiency.

[0038] In addition, it should be noted that the clot catcher provided in this embodiment is a disposable medical device. Therefore, in order to reduce the manufacturing cost of the clot catcher as much as possible and make the clot catcher meet medical requirements, the holding part 10 and the capturing part 20 in this embodiment are both made of disposable medical plastics, such as medical PVC material.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
