[0002] Brachial vein blood sampling is the process of drawing a blood sample from the brachial vein in the upper arm for various laboratory tests. This procedure is one of the most common procedures in medical practice, used to diagnose diseases, monitor health conditions, or evaluate the effectiveness of treatment.

[0003] Brachial vein blood collection is the most common blood collection method. Due to improper pressure location, pressure time, or incorrect technique, bleeding and hematoma often occur at the puncture site. In particular, after blood collection from children, parents or medical staff need to apply pressure to the puncture site to stop the bleeding. However, because children tend to move around, the effect of pressure to stop the bleeding is not ideal. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] This application provides a strap-type brachial vein compression hemostat, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0029] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] Please see Figure 1-9 In this embodiment, a brachial vein compression hemostat is provided, comprising: a compression block 1, a connecting strap 3 connected to one side of the compression block 1, a fixing strap 4 connected to the other side of the compression block 1, a connecting block 5 connected to one side of the fixing strap 4, a sponge block 103 provided at the bottom of the compression block 1, a replacement component disposed between the sponge block 103 and the compression block 1, for quick replacement of the sponge block 103, the replacement component including: a sliding groove 101, a sliding plate 102, a connecting plate 2 and an insertion rod 201; and a fixing component disposed between the connecting block 5 and the connecting strap 3, for fixing the compression block 1 to the child, the fixing component including: a connecting groove 501, a moving groove 502 and a moving plate 503.

[0032] The compression block 1 and the sponge block 103 effectively compress the puncture site, preventing bleeding and hematoma due to insufficient pressure. The sponge block 103 can be replaced, allowing the compression block 1 to be reused. Furthermore, compared to traditional compression, the compression block 1 can be fixed at the puncture site by the fixing component, allowing the child to move freely, greatly improving comfort, facilitating implementation, reducing the workload of nurses, and adapting to different arm sizes of children, thus improving applicability.

[0033] Example 2

[0034] Based on embodiment 1, the bottom of the pressing block 1 is provided with a sliding groove 101, the top of the sponge block 103 is connected to a sliding plate 102, and the sliding plate 102 is slidably connected to the sliding groove 101. The top of the sliding plate 102 is provided with two symmetrically arranged fixing holes 104. The top of the pressing block 1 is provided with two insertion holes 2011, and the two insertion holes 2011 correspond to the positions of the fixing holes 104. An insertion rod 201 is inserted inside the insertion hole 2011, and the bottom end of the insertion rod 201 extends into the fixing hole 104. The top end of the insertion rod 201 is connected to a connecting plate 2. The top of the pressing block 1 is provided with two symmetrically arranged reset holes 2021, and a reset spring 202 is connected inside the reset hole 2021. The top end of the reset spring 202 is connected to the connecting plate 2.

[0035] When the sponge block 103 needs to be replaced, pull up the connecting plate 2, causing the connecting plate 2 to separate the insert rod 201 from the fixing hole 104 and retract it into the insertion hole 2011, thus releasing the locking and fixing of the slide plate 102. Then, take the slide plate 102 out of the slide groove 101 and align the new slide plate 102 with the slide groove 101 and insert it. During this process, the connecting plate 2 is still pulled up to prevent the insert rod 201 from blocking the slide plate 102 from sliding in. As the connecting plate 2 is pulled up, the return spring 202 is stretched and undergoes elastic deformation to generate elastic force. After the slide plate 102 has completely slid into the slide groove 101, the fixing hole 104 on the slide plate 102 corresponds to the insertion hole 2011. Then, the connecting plate 2 can be released, allowing the connecting plate 2 to rebound under the elastic force of the return spring 202, so that the bottom end of the insert rod 201 is inserted into the fixing hole 104, completing the replacement of the slide plate 102 and the sponge block 103.

[0036] Example 3

[0037] Based on embodiment 1, the bottom of the connecting strap 3 is connected to a first Velcro 301, the top of the fixing strap 4 is connected to a second Velcro 401, the connecting block 5 has a connecting groove 501 on one side, and the connecting groove 501 is matched with the size of the connecting strap 3. The top of the connecting block 5 has a moving groove 502, which communicates with the connecting groove 501. The moving groove 502 has a moving plate 503 inside, and the bottom of the moving plate 503 has multiple teeth. The bottom of the moving plate 503 extends into the connecting groove 501. The top of the connecting block 5 has two symmetrically arranged openings 504, and a compression spring 505 is connected inside the openings 504. The top of the compression spring 505 is connected to the moving plate 503.

[0038] When hemostasis is required at the puncture site, move the compression block 1 above the puncture site and position the sponge block 103 towards the puncture site. Then, press the compression block 1 onto the puncture site so that the sponge block 103 can apply pressure to stop the hemorrhage. Next, wrap one end of the connecting strap 3 around the child's arm and pass it through the connecting groove 501. As the connecting strap 3 passes through the connecting groove 501, pull up the moving plate 503 to allow the connecting strap 3 to pass smoothly through the connecting groove 501, avoiding obstruction of the connecting strap 3 by the teeth on the moving plate 503. When the moving plate 503 is pulled up, the compression spring 505 is stretched and undergoes elastic deformation to accumulate elastic force. Then, adjust the connecting strap 3 according to the size of the child's arm and the required pressure at the puncture site. The distance of the groove 501 allows the compression block 1 to effectively compress the puncture site, improving applicability. After the position of the connecting strap 3 is adjusted, the moving plate 503 can be released. At this time, the moving plate 503 rebounds under the action of the compression spring 505, so that the moving plate 503 presses and fixes the connecting strap 3 in the connecting groove 501. The teeth on the moving plate 503 can increase the fixing effect of the connecting strap 3, preventing the connecting strap 3 from loosening and shifting backward, which would affect the compression and hemostasis effect of the compression block 1 on the puncture site. Then, through the setting of the first Velcro 301 and the second Velcro 401, the connecting strap 3 passing through the connecting groove 501 can be attached to the fixing strap 4, preventing the excess connecting strap 3 from swinging around and affecting the wearer's comfort.
