Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

In the following description, the terms "left", "right", "upper", "lower", "front", "rear", "inner" and "outer" are relative terms, and are not intended to be exhaustive.

A blood collection tube fixing device comprises an arm fixing device 1 and a blood collection tube fixing device 2.

Referring to fig. 1, the arm fixing apparatus 1 includes a base block 11. An annular fixing sleeve 12 is arranged on the right side of the base block 11. The annular fixing sleeve 12 is made of elastic materials and can stretch and retract circumferentially. The elastic material adopted in the embodiment is rubber material, and can be firmly sleeved on the arm of a patient. For those skilled in the art, the annular fixing sleeve 12 may also be made of a memory metal elastic sheet, and is flat and vertical in a normal state, so that when the annular fixing sleeve needs to be firmly sleeved on the arm of the patient, the annular fixing sleeve touches the arm of the patient, and is automatically and firmly arranged on the arm of the patient, similar to a snap roll structure, and can be selected according to practical situations.

Referring to fig. 2, the blood collection tube fixing device 2 includes a fixing plate 21. The right side of the fixing plate 21 is connected to the base block 11. The fixing plate 21 is provided with a fixing block 23 on the left side. The fixing plate 21 is provided with four pockets 22 below the fixing blocks 23. The cuff 22 is made of an elastic member such as a rubber ring or the like. The collar 22 may also be of an adjustable caliber structure, which is a relatively prior art, and not described in any great detail herein, and those skilled in the art may use corresponding schemes according to practical situations. The blood collection tube 3 can be fixedly sleeved at the sleeve opening 22, and the embodiment can be used for fixing four blood collection tubes 3. For those skilled in the art, the number of the cuffs 22 may be one, two, three, five, six, etc., and is not limited to four in the present embodiment, and the number of the fixed blood collection tubes 3 may be changed accordingly. The fixed block 23 is provided with communication holes 24 corresponding to the positions and the numbers of the sleeve openings 22.

The communication pipe 4 is provided with the needle return head 5 far away from fixed block 23 one end, is close to fixed block 23 one end UNICOM have with the same number of branch pipe 41 of sleeve mouth 22. The branch tubes 41 are respectively connected to the corresponding blood collection tubes 3 through the corresponding communication holes 24. The branch pipes 41 are each provided with an opening/closing device 6. The opening/closing device 6 may be a commercially available switching structure, and is not described here too much because it is a conventional technology.

When the medical staff takes blood, the annular fixing sleeve 12 is sleeved at the arm of the patient to be firmly fixed. The blood collection tube 3 is fitted into the cuff 22. When medical personnel take blood, the blood collection tube 3 is not required to be additionally fixed, and the blood collection efficiency can be greatly improved.

Because four blood collection tubes 3 can be fixed simultaneously, when the number of the plurality of blood collection tubes 3 is required to be collected, the opening and closing device 6 can be opened and closed in sequence to be pumped into the corresponding blood collection tubes 3 in sequence. If the number of the collected blood collection tubes 3 is greater than four, the blood collection tubes 3 filled with blood can be taken down, and the empty blood collection tubes 3 can be replaced, so that the operation is very convenient.

Further improvements of the present experiment can be further extended according to the above cases, and various novel embodiments are provided.

As a second embodiment of the present utility model, on the basis of example 1, referring to fig. 3 and 4, the opening/closing device 6 includes a base 61. The base 61 is provided with side walls 62 on both sides. A through portion through which the communication pipe 4 passes is formed between the two side walls 62. The two side walls 62 are provided with guide grooves 63. The guide groove 63 is slidably provided with a slider 64 that moves in the extension direction thereof. An extrusion 65 is provided between the two sliders 64. When the sliding block 65 is positioned at the upper end of the guide groove 63, the branch pipe 41 is not extruded, and when the sliding block 65 is positioned at the lower end of the guide groove 63, the branch pipe 41 is completely extruded by the extrusion part 65, so that the branch pipe 41 is blocked.

By adopting the opening and closing device 6 with the structure, not only the blocking of the branch pipe 41 can be realized, but also the blood sampling speed can be adjusted, and when a patient is untimely due to too fast blood sampling, the blood sampling speed can be adjusted, and the discomfort of the patient is reduced.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
