[0035] In one embodiment, if Figure 1 and Figure 2 As shown, the collecting and fixing device comprises an arm pillow 100, a positioning member, a first fixing member and a second fixing member. The arm pillow 100 can be made of a material with moderate hardness, such as a hard sponge material.

[0036] The positioning member is arranged on the arm pillow 100 to fix the arm pillow 100 at a set position. For example, the positioning member can fix the arm pillow 100 on the bed, thereby preventing the arm pillow 100 from shaking during the collection process.

[0037] The arm pillow 100 includes a first fixing area 110 and a second fixing area 120. The first fixing area 110 is used to place the forearm of the subject, and the first fixing member is arranged in the first fixing area 110, and the first fixing member is used to fix the forearm of the subject in the first fixing area 110. The second fixing area 120 is used to place the finger of the subject, and the second fixing member is arranged in the second fixing area 120, and the second fixing member is used to fix the finger of the subject in the second fixing area 120.

[0038] When in use, the arm pillow 100 is first fixed at a set position using a positioning piece, and then the arm of the person being collected is placed in the first fixing area 110 of the arm pillow 100 and fixed by the first fixing piece, and then the palm and / or fingers of the person being collected are placed in the second fixing area 120 and fixed by the second fixing piece. Since the arms and fingers of the person being collected are fixed, that is, the part below and above the wrist of the person being collected are fixed, when collecting radial artery blood gas samples, the patient's arm will not swing back and forth, the arterial pulsation point is fixed, and the blood vessel will not slide, thereby improving the puncture success rate, and being able to collect radial artery blood gas samples from agitated patients more safely. Of course, the collection and fixing device of the utility model is not limited to collecting radial artery blood gas samples, and can also be used for other purposes.

[0039] In one embodiment, in order to more firmly fix the arm of the subject, the first fixing area 110 is further provided with a third fixing member, which is arranged at an interval from the first fixing member and is also used to fix the forearm of the subject to the first fixing area 110. Since the arm part below the wrist of the subject is fixed by two fixing members, and the fingers above the wrist of the subject are fixed by one point, this three-point fixing method can more firmly fix the arm and fingers of the subject to the arm pillow 100.

[0040] Furthermore, the positioning member includes a first restraining belt 210 and a second restraining belt 220, and the first restraining belt 210 and the second restraining belt 220 are used to be fixedly connected to the set position to fix the arm pillow 100.

[0044] Preferably, in order to more firmly fix the fingers of the person being collected, there are multiple finger sleeves 400 and they are arranged in parallel. The multiple finger sleeves 400 correspond to the fingers of the person being collected one by one. For example, five finger sleeves 400 can be arranged in a staggered manner according to the length of the five fingers. In other embodiments, only one finger sleeve 400 can be provided to fix only the middle finger of the person being collected. Of course, two, three or four finger sleeves 400 can also be provided. In order to take into account both convenience and firmness of fixation, it is preferred to provide three finger sleeves 400 to fix the index finger, middle finger and ring finger.

[0045] In another embodiment, the second fixing member includes a restraining glove (not shown in the drawings) and a fingertip, and the restraining glove is fixed to the second fixing area 120 to fix the palm of the subject. The back of the hand of the restraining glove can be fixed to the second fixing area 120 by glue or needle and thread. When in use, the palm of the subject is first inserted into the restraining glove, and then the arm of the subject is fixed by the first fixing member and the third fixing member.

[0046] The finger cuffs are arranged in the restraining gloves, and the finger cuffs can be inserted into the fingers of the person being collected to fix the fingers of the person being collected. The number of finger cuffs in the restraining gloves can be flexibly set, and can be one, two, three, four or five. In order to take into account both convenience and firmness of fixation, only three finger cuffs can be set to correspond to the fixed index finger, middle finger and ring finger. The restraining gloves can limit the large-scale rolling of the palm, and the finger cuffs can restrain the fingers more accurately.

[0047] In one embodiment, in order to improve the comfort of the subject, the arm pillow 100 is provided with a long groove 500 corresponding to the forearm to accommodate the forearm, thereby increasing the contact area between the arm pillow 100 and the forearm of the subject and reducing the pressure on the forearm of the subject. Preferably, the cross section of the long groove 500 is arc-shaped, and the long groove 500 with an arc-shaped cross section is similar to the contour of the forearm, which is more comfortable.
