Description

Technical Field

[0001] This utility model relates to the field of fingertip blood collection technology, and in particular to a fingertip blood collection kit. Background Technology

[0002] Finger-prick blood collection is a sampling method that obtains capillary blood by puncturing the surface of the skin. A typical finger-prick blood collection kit includes a lancet, a pipette, cotton swabs, and medical alcohol. The procedure for medical personnel to collect finger-prick blood involves disinfecting the patient's fingertip with medical alcohol, puncturing the fingertip with a lancet, and collecting the blood that seeps from the wound using a pipette for blood testing.

[0003] However, since the lancet punctures the capillaries at the fingertip, and the blood content in capillaries is relatively low, insufficient for laboratory testing, nurses often squeeze the patient's fingertip to increase the amount of bleeding at the wound. Children are more sensitive to pain, and if the fingertip is squeezed forcefully during blood collection, it will aggravate the pain at the wound, causing secondary pain to the child and making the child resist the blood collection process. This is not conducive to medical staff directly collecting blood from the child's fingertip. Therefore, this application proposes a fingertip blood collection kit. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art where forcefully squeezing the fingertip exacerbates the pain at the wound site on a child's fingertip, and to propose a fingertip blood collection kit.

[0005] The technical solution of this utility model is: a fingertip blood collection kit, including an upper shell and a puncture needle slidably installed in the upper shell, wherein the upper shell is provided with a fixing mechanism for assisting blood collection;

[0006] The fixing mechanism includes a slider fixedly fitted onto the surface of the puncture needle. A first spring is fixedly connected to one side of the slider. One end of the first spring is fixedly connected to the inside of the upper housing. An internal groove is provided on one side of the upper housing, and a first blocking block, a second blocking block, and a third blocking block are fixedly connected inside the upper housing. A lower housing is threadedly connected to one side of the upper housing. An elastic cloth is fixedly connected to the inside of the lower housing. A soft pad is fixedly connected to the side of the elastic cloth near the inner wall of the cannula. Soft ropes are fixedly connected to both ends of the soft pad. Circular holes for the soft ropes to cross and pass through are symmetrically opened on the inside of the upper housing.

[0007] Optionally, a fixed block and a moving block are fixedly connected to both ends of the soft rope, a sliding groove is provided on the lower housing, the sliding groove is slidably connected to the moving block, and a second spring is fixedly connected inside the sliding groove. The second spring is fixedly connected to the moving block. A through groove is provided on the fixed block, and a long rod that is slidably connected to the through groove is fixedly connected to the moving block. A track is provided inside the through groove.

[0008] Optionally, the track includes a return section, a fixed section, and an exit section, and a guide groove is provided on one side of the track.

[0009] Optionally, a crossbar is rotatably connected to the surface of the long rod, and a circular block that slides on the track is fixedly connected to one end of the crossbar. A limiting groove is provided on the surface of the long rod to limit the angle of the crossbar.

[0010] Optionally, the guide groove is in the shape of a figure eight.

[0011] Optionally, the lower housing is fixedly connected to an arc-shaped tube on the side near the elastic fabric, allowing the two ends of a soft rope to pass through each other.

[0012] Optionally, the second blocking block is made of lightweight plastic and is inclined within the upper housing, and one side of the slider is tapered.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] This invention, by setting a fixing mechanism, allows the moving block to drive one end of the soft rope to move, causing the circular hole formed by the middle of the soft rope and the soft pad to contract, and squeezing the soft pad into contact with the child's fingertip. This allows the blood from the child's fingertip to gather at the wound, which helps to increase the amount of blood collected from the fingertip and reduces the need for medical staff to manually squeeze the child's fingertip while drawing blood, thus improving the efficiency of finger blood collection for medical staff.

[0015] Furthermore, by setting up circular blocks to slide within the track, the moving blocks can reciprocate within the groove, causing the soft pads to repeatedly press and contact the child's fingertips. When the blood volume in the child's fingertips is insufficient, repeated pressing of the fingertips can cause multiple congestion of the fingertips, and avoids secondary pain to the child's wound caused by medical staff pressing the child's fingertips too hard, making it easier to draw blood for testing.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figures 1 to 4 As shown, the present invention proposes a fingertip blood collection kit, including an upper shell 1 and a puncture needle 101 slidably installed in the upper shell 1. The upper shell 1 is provided with a fixing mechanism 2 for assisting blood collection. Medical staff will use the puncture needle 101 to puncture the skin of the child's fingertip, causing the capillaries in the subcutaneous tissue to rupture and seep out blood. Medical staff will use a disposable medical pipette to collect the blood for testing.

[0023] The fixing mechanism 2 includes a slider 201 fixedly sleeved on the surface of the puncture needle 101. A first spring 202 is fixedly connected to one side of the slider 201. One end of the first spring 202 is fixedly connected to the upper housing 1. An internal groove 203 is provided on one side of the upper housing 1. A first blocking block 204, a second blocking block 205 and a third blocking block 206 are fixedly connected inside the upper housing 1. The second blocking block 205 is made of lightweight plastic and is inclined inside the upper housing 1. One side of the slider 201 is conical. A lower housing 207 is threadedly connected to one side of the upper housing 1. Elastic fabric 208 is fixedly connected to the inner side of the lower housing 207. A soft pad 209 is fixedly connected to the side of the elastic fabric 208 near the inner wall of the sleeve. Soft ropes 210 are fixedly connected to both ends of the soft pads 209. Symmetrical circular holes 211 are opened on the inner side of the upper housing 1 for the soft ropes 210 to pass through. An arc-shaped tube 226 is fixedly connected to the side of the lower housing 207 near the elastic fabric 208, allowing the ends of the soft ropes 210 to pass through. A child's fingers can pass through... The lower housing 207 is inserted into the upper housing 1, and the fingertip touches the inner wall of the built-in groove 203. At this time, the puncture needle 101 and the slider 201 are fixed together, and the slider 201 is located between the second blocking block 205. The spring is in a stretched state. Since the second blocking block 205 is made of lightweight plastic and the connection between it and the upper housing 1 is adhesive, the second blocking block 205 can separate from the inner wall of the upper housing 1 under certain pressure. Due to the pressure applied by the medical staff, the slider 201... The slider 201 can separate the second blocking block 205 from the inner wall of the upper housing 1, and continue to drive the puncture needle 101 and the spring to move. When the slider 201 contacts the first blocking block 204, the puncture needle 101 can stop moving inside the upper housing 1 and puncture the skin of the child's fingertip. Meanwhile, the soft pad 209 can be pulled by the soft rope 210 to move inside the lower housing 207 and compress the elastic cloth 208 to deform. At this time, the soft rope 210 and the soft pad 209 form a whole. The two ends of the soft rope 210 are respectively The soft rope 210 passes through both ends of the arc-shaped tube 226 and enters the interior of the lower housing 207 through the round hole 211, so that the soft rope 210 is in a crossed state. The middle part of the soft rope 210 and the soft pad 209 form a retractable round hole. When the two ends of the soft rope 210 are pulled, the area of ​​the round hole shrinks, so that the soft pad 209 is tightly attached to the fingertip of the child. This can maintain sufficient blood volume at the fingertip and reduce the pain caused by medical staff squeezing the fingertip of the child due to insufficient bleeding after puncture.

[0024] In this implementation, such as Figure 3As shown, a fixed block 212 and a moving block 213 are fixedly connected to both ends of the soft rope 210, respectively. The fixed block 212 and the moving block 213 are at the same height and on the same straight line. A sliding groove 214 is provided on the lower housing 207, and the moving block 213 can slide freely in the sliding groove 214. The sliding groove 214 and the moving block 213 are slidably connected, and a second spring 215 is fixedly connected in the sliding groove 214. In the initial state, the moving block 213 is located at one end of the sliding groove 214 and the second spring 215 is fixedly connected in the sliding groove 214. The second spring 215 is in a relaxed state. The second spring 215 is fixedly connected to the moving block 213. A through groove 216 is provided on the fixed block 212. A long rod 217 that is slidably connected to the through groove 216 is fixedly connected to the moving block 213. A track 218 is provided inside the through groove 216. When the moving block 213 moves toward the fixed block 212, the long rod 217 on one side of the moving block 213 will enter the through groove 216, which can fix or release the long rod 217 in the through groove 216.

[0025] In this implementation, such as Figure 2 and Figure 3 As shown, track 218 includes a return section 219, a fixed section 220, and an exit section 221. A guide groove 222 is provided on one side of track 218, and the guide groove 222 is V-shaped. A crossbar 223 is rotatably connected to the surface of a long rod 217. A circular block 224 that slides on track 218 is fixedly connected to one end of the crossbar 223. A limiting groove 225 is provided on the surface of the long rod 217 to limit the angle of the crossbar 223. The crossbar 223 on one side of the long rod 217 and the circular block 224 at one end of the crossbar 223 will... Always located within the limiting groove 225, the connection points between the return section 219, the fixed section 220, and the exit section 221 are all equipped with guide angles. When the long rod 217 enters the through groove 216, the round block 224 at one end of the crossbar 223 will enter the guide groove 222 and thus enter the return section 219. It will then enter the fixed section 220 along the guide angle in the return section 219, and then enter the exit section 221 along the guide angle in the fixed section 220. Finally, it will enter the guide groove 222 and move out of the through groove 216.

[0026] In this embodiment, medical personnel insert the child's fingertip into the lower housing 207 and the upper housing 1 until the fingertip touches the inner wall of the built-in groove 203. At this time, the medical personnel push the moving block 213 to move towards the fixed block 212 in the slide groove 214. The second spring 215 is in a compressed state, and the long rod 217 on one side of the moving block 213 begins to enter the through groove 216 in the fixed block 212. When the round block 224 at one end of the crossbar 223 enters the return section 219 from the guide groove 222 and reaches the fixed section 220, the moving block 213 is fixed in a specific position in the slide groove 214. During this process, the moving block 21... 3. Pulling one end of the soft rope 210 causes the circular hole formed by the middle of the soft rope 210 and the soft pad 209 to contract, thereby squeezing the soft pad 209 onto the child's fingertip, causing sufficient blood to pool at the fingertip. At this time, the medical staff presses the slider 201, causing the slider 201 to break the second blocking block 205. Under inertia, the puncture needle 101 pierces the skin of the child's fingertip, causing bleeding. The slider 201 is blocked by the first blocking block 204 and cannot continue to move. After the medical staff releases control of the slider 201, the first spring 20... 2. Pull the slider 201 and the puncture needle 101 towards the third blocking block 206 to complete the retrieval of the puncture needle 101, preventing the puncture needle 101 from protruding and causing accidental injury. If the blood volume at the child's fingertip is still insufficient, medical staff can press the moving block 213 again, causing the round block 224 to move from the fixed section 220 to the exit section 221 and out of the guide groove 222, thus releasing the fixed restriction between the long rod 217 and the through groove 216. At this time, under the action of the second spring 215, the moving block 213 moves to the initial position in the slide groove 214, and the moving block 213... The soft rope 210 at one end is in a slack state, so that the soft pad 209 will not put pressure on the child's fingertip. When the round block 224 moves from the return section 219 to the fixed section 220 again, the soft pad 209 will put pressure on the child's fingertip again, thus forming repeated pressing on the child's fingertip, causing repeated congestion of the child's fingertip. This is conducive to the flow of sufficient blood from the child's fingertip, which helps medical staff to manually press on the child's injured fingertip and avoids aggravating the child's pain due to strong pressing. It also makes it easier for medical staff to quickly and easily perform fingertip blood collection on children.
