Description

Technical Field

[0001] This application relates to the field of blood collection tube sleeve technology, and in particular to blood collection tube sleeves that are easy to assemble and use. Background Technology

[0002] Traditional methods of storing blood collection tubes involve standardized trays or fixed-size tube racks. This leads to limitations in the uniform placement of tubes, including wasted space. During blood collection, tubes from multiple patients are often placed together in a disorganized manner, making it difficult for medical staff to quickly retrieve them from the racks. Furthermore, haphazardly inserted tubes easily result in missed collections. Additionally, nursing staff may forget the correct blood collection order, leading to incorrect results and potentially inaccurate test findings.

[0003] Therefore, in response to the above issues, the applicant provided a blood collection tube set that is easy to combine and use. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a blood collection tube sleeve that is easy to use in combination.

[0005] The blood collection tube sleeve provided in this application, which is easy to combine and use, adopts the following technical solution:

[0006] A blood collection tube sleeve for easy assembly includes a tube sleeve body, with a retaining ring fixedly connected to the outer circumference of the tube sleeve body. The tube sleeve body and the retaining ring are combined to form a unit tube sleeve assembly. The tube sleeve body in the unit tube sleeve assembly can be arbitrarily snapped into the retaining rings of adjacent unit tube sleeve assemblies. A blood collection tube can be placed in the tube sleeve body.

[0007] Furthermore, the number of unit tube sleeve assemblies is multiple with different colors, and the color of each unit tube sleeve assembly matches a blood test tube of a certain color.

[0008] Furthermore, the color of the test tube sleeve body in each unit tube sleeve assembly matches the color of a cap of the blood test tube (existing blood test tubes are distinguished by color according to the blood collection order, which are in turn divided into blood collection test tubes with blue caps, black caps, red caps, orange caps, yellow caps, green caps, purple caps and gray caps).

[0009] Furthermore, the retaining ring is a PVC buckle, and one side of the retaining ring has an opening for placing the test tube sleeve body.

[0010] Furthermore, the test tube sleeve body has a groove in the inner diameter of the top opening, and a soft ring is embedded in the groove, which causes the top opening of the test tube sleeve body to form a soft plastic constriction.

[0011] Furthermore, a ring buckle is fixedly connected to the outer circumference of the test tube sleeve body in the middle, and the ring buckle is attached to the top surface of the retaining ring.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. In this utility model, medical staff take multiple unit tube sleeves of the required color according to the blood drawing order, and then assemble them into a row of unit tube sleeves (that is, the test tube sleeve body in the later unit tube sleeve is inserted into the retaining ring of the previous unit tube sleeve, and so on to form a row), corresponding to one patient drawing blood. Then, multiple blood test tubes of different colors are placed one by one into the test tube sleeve bodies of the multiple unit tube sleeves of different colors. The visual operation combined with the unit design greatly reduces the possibility of accidental or missed blood draws.

[0014] 2. This invention avoids the risk of cross-contamination that may occur when multiple patients' blood collection tubes are placed together by individually placing them in an array of sleeve assemblies. Furthermore, the sleeve assemblies can be made of soft plastic material with a color matching the different colors of the blood collection tubes, ensuring consistent color matching, clear color differentiation, and high visual appeal, further reducing the possibility of accidental or missed aspirations. Because the sleeve assemblies are made of plastic, their elasticity and flexibility effectively absorb external impacts, allowing for repeated use and avoiding the need for single-use disposal.

[0023] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0024] This application discloses blood collection tube sleeves that are easy to combine and use. Example 1

[0025] like Figure 1-2 As shown, the blood collection tube sleeve, which is easy to assemble, includes a sleeve body 1. A retaining ring 2 is fixedly connected to the outer circumference of the sleeve body 1. The sleeve body 1 and the retaining ring 2 are combined to form a unit sleeve assembly. The sleeve body 1 in the unit sleeve assembly can be arbitrarily snapped into the retaining rings 2 of adjacent unit sleeve assemblies. The sleeve body 1 is a cylindrical structure with an open top. A blood collection tube 5 can be placed inside the sleeve body 1, and the blood collection tube 5 can be inserted into the sleeve body 1 through its top opening. The unit sleeve assembly design facilitates assembly. Based on the needs of a patient requiring blood collection, several unit sleeve assemblies corresponding to that patient can be taken and then combined to form a row of unit sleeve assemblies. This modular design greatly reduces the possibility of accidental or missed blood collection.

[0026] like Figure 1-2 As shown, the number of unit tube sleeve assemblies is multiple with different colors, and the color of each unit tube sleeve assembly matches a blood test tube 5 of a certain color. The color of the test tube sleeve body 1 in each unit tube sleeve assembly matches the color of a cap 50 of the blood test tube 5. The existing blood test tubes 5 are distinguished by color according to the blood collection order, which are, in order, blood collection tubes with blue caps, black caps, red caps, orange caps, yellow caps, green caps, purple caps, and gray caps. The colors of the test tube sleeve bodies 1 in each unit tube sleeve assembly also correspond one-to-one with blue, black, red, orange, yellow, green, purple, and gray test tube sleeve bodies. The test tube sleeve bodies 1 are made of PVC material, which has the advantages of being soft, tough, and malleable. Each color of the test tube sleeve body 1 can be obtained by adding corresponding color pigments or dyes to the PVC base. The test tube sleeve body, which uses multiple unit tube sleeve components of different colors, matches the color of the blood tube cap. The color distinction is more obvious, more visually acceptable, and highly distinguishable. The combination of visual operation and unit design further reduces the possibility of accidental or missed aspiration.

[0027] Alternatively, each color of the test tube sleeve body 1 can also be a modular test tube sleeve body. This modular test tube sleeve body includes an upper half 11 and a lower half 12 integrally connected to the upper half 11. The upper and lower halves 11 and 12 are spliced ​​together. The upper half 11 of this modular test tube sleeve body is a color matching the cap color of the blood test tube (e.g., a blue upper half), and its lower half 12 is a transparent lower half. The modular test tube sleeve body can be manufactured using a two-color co-extrusion process, that is, by using two independent extruders to feed raw materials of different colors or materials (e.g., PC, PE, PP), and achieving layered composite through a co-extrusion mold to form a one-time modular test tube sleeve body. This modular test tube sleeve body design allows the lower half to form a transparent window. When the blood collection tube is placed inside the test tube sleeve body 1, a scanning gun can be used to directly scan the blood collection tube through the lower half 12 of the test tube sleeve body 1. barcode Simply scan the label; see the attached document for details. Figure 4 .

[0028] In addition, within each unit tube sleeve assembly, according to the blood collection sequence of each blood collection tube 5, a numerical label (such as Arabic numerals 1, 2, 3, etc.) is fixed to the outer wall of each tube sleeve body 1 from front to back (e.g., printed or affixed). Each unit tube sleeve assembly has a color corresponding to a numerical label (i.e., a numerical code). Blood collection is performed sequentially according to the numerical labels (i.e., numerical codes) from smallest to largest, effectively preventing nurses from easily making mistakes in the blood collection sequence due to forgetting the order. lead to The problems of sample cross-contamination and test result deviation are further reduced, thus lowering the possibility of false or missed sampling.

[0029] like Figure 1-3 As shown, the retaining ring (2) is a PVC buckle, and one side of the retaining ring (2) has an opening for placing the test tube sleeve body (1). The retaining ring (2) is a commonly used plastic buckle material (or other buckles such as metal spring clips, etc.). The working principle of the retaining ring 2 is to utilize the elastic deformation generated by the plastic when it is subjected to force. When it is necessary to insert the test tube sleeve body 1, the opening of the retaining ring 2 can be pried open to deform the retaining ring 2 to adapt to the size of the test tube sleeve body 1. When the opening is released, the retaining ring 2 will automatically tighten using its own elastic restoring force, thereby firmly fixing the object. In addition, the PVC buckle can also be the same color as the test tube sleeve body 1 that it is fixedly matched with.

[0030] like Figure 1-2As shown, the different colored caps of blood collection tubes 5 correspond to different orders of blood collection tubes 5 during venous blood draws. For example, blood collection tubes 5 without additives are selected with red caps, blood collection tubes 5 with pink caps are selected for citrate or erythrocyte sedimentation rate tubes, blood collection tubes 5 with white caps are selected for coagulant tubes, blood collection tubes 5 with green caps are selected for heparin tubes, and blood collection tubes 5 with purple caps are selected for EDTA. The test tube sleeves 1 on the same colored non-adhesive paper 6 are placed together in the same drawer for easy identification and retrieval by medical staff.

[0031] The implementation principle of the blood collection tube sleeve in this application embodiment, which is easy to combine, is as follows:

[0032] When a patient has venous blood drawn, multiple tubes of blood need to be drawn in the order of venous blood drawing. The caps of the blood collection tubes 5 for each tube of blood are different colors. In order to facilitate the independent placement of the multiple blood collection tubes 5 for the patient, this unit tube sleeve assembly is required. Its usage method is as follows.

[0033] Medical staff match the number of blood collection tubes 5 with different colored caps used by the patient to multiple unit tube sleeve assemblies of the same number and color. Based on the blood collection order of the blood collection tubes 5 with different colored caps, they are then assembled into a row of unit tube sleeve assemblies (i.e., the tube sleeve body of the subsequent unit tube sleeve assembly is inserted into the retaining ring of the preceding unit tube sleeve assembly, and so on, forming a row). The specific method of assembling multiple unit tube sleeve assemblies is as follows: the retaining ring 2 of the preceding unit tube sleeve assembly is opened to form an opening, deforming the retaining ring 2 to adapt to the size of the tube sleeve body 1 of the subsequent unit tube sleeve assembly. After inserting the tube sleeve body 1 into the retaining ring 2, the opening is released, and the retaining ring 2 will automatically tighten using its own elastic restoring force, thereby firmly fixing the tube sleeve body 1 of the subsequent unit tube sleeve assembly, and so on, forming a row of unit tube sleeve assemblies. Then, the blood collection tubes 5 with different colored caps 50 are placed one by one into the corresponding tube sleeve body 1 of the same color. By arbitrarily combining, disassembling, adding, or subtracting the number of combined cannula components to suit the number of blood collection tubes 5 used by the patient, the visual operation combined with the modular design greatly reduces the possibility of accidental or missed aspirations. Furthermore, assembly is convenient, ensuring 100% utilization of the cannula body 1 and avoiding space waste. Multiple blood collection tubes 5 from one patient can be placed individually within a row of unit cannula components. This avoids the cross-contamination risks that may result from placing multiple patients' blood collection tubes 5 together (as in existing test tube racks). Example 2

[0034] like Figure 5-6As shown, this embodiment is basically the same as the embodiment in Example 1, except that the test tube sleeve body 1 and the retaining ring can also be made of transparent soft plastic material. The elasticity and flexibility of the test tube sleeve body 1 made of soft plastic material can effectively absorb external impact. The transparent material allows direct observation of the label (such as patient name, barcode and sample type) of the blood drawing tube 5, without the need to frequently remove the blood drawing tube 5 to observe the label (such as patient name, barcode and sample type), thus improving operational efficiency. The outer circumference of the test tube sleeve body 1 is adhered with colored non-adhesive paper 6. The colored non-adhesive paper 6 comes in various colors, each corresponding to a different color of the cap 50 of the blood collection tube 5. These different colors of the cap 50 correspond to different sequences of blood collection tubes 5 during venous blood draws. For example, tubes without additives use a red cap, citrate or erythrocyte sedimentation rate tubes use a pink cap, coagulant tubes use a white cap, heparin tubes use a green cap, and EDTA tubes use a purple cap. Furthermore, test tube sleeve bodies 1 with the same color of colored non-adhesive paper 6 can be stored together in a drawer box for easy identification and retrieval by medical staff.

[0035] Additionally, a groove can be provided on the inner diameter of the top opening of the test tube sleeve body 1, and a soft ring 101 is embedded in the groove. The soft ring 101 forms a soft plastic constriction at the top opening of the test tube sleeve body 1. The soft plastic constriction prevents the blood collection tube 5 from slipping out when inserted into the constriction and is squeezed. For details, please refer to the attached instruction manual. Figure 7 As shown. Example 3

[0036] like Figure 8 As shown, the implementation methods of this embodiment and Embodiment 1 are basically the same, except that: for the blood collection tube sleeve that is easy to use in combination, a ring buckle 100 is fixedly connected to the outer circumference of the middle part of the tube sleeve body 1. The ring buckle 100 fits against the top surface of the retaining ring 2. The function of the ring buckle 100 is that when the operator picks up the two ends of the combination of multiple unit tube sleeve components, the lower part of the tube sleeve body 1 may cause multiple blood collection tubes 5 to tilt or move downward under the action of gravity, which may cause the tube sleeve body 1 to slip off the retaining ring 2. The ring buckle 100 can limit the tube sleeve body 1, thus avoiding the risk of it slipping off the retaining ring 2.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
