Abstract
Description
Technical Field
[0001] This invention relates to the field of medical blood collection, and more particularly to a newborn blood collection device for gene screening. Background Technology
[0002] Newborn genetic screening requires blood sampling. The conventional method involves holding the newborn's wrist and inserting a lancet into a blood vessel in the wrist, or holding the newborn's ankle and inserting a lancet into a blood vessel in the heel. Both methods require a medical staff member to stabilize the newborn's wrist with one hand and control the lancet with the other. When the newborn struggles, this procedure becomes difficult to perform smoothly to avoid injury from the lancet, requiring an additional medical staff member to assist. Therefore, it is difficult for a single medical staff member to complete the newborn blood sampling. Furthermore, if the medical staff does not control the pressure properly when holding the newborn's wrist, it can cause discomfort to the newborn's wrist and even affect the normal blood flow in the wrist. This not only affects the efficiency of newborn blood sampling but also wastes the time that medical staff can spend caring for other newborns. Summary of the Invention
[0003] To overcome the shortcomings of medical staff having difficulty completing newborn blood collection independently and the discomfort caused by holding a newborn's wrist, this invention provides a newborn blood collection device for gene screening.
[0004] The technical solution is as follows: A newborn blood collection device for gene screening includes a U-shaped sleeve, a U-shaped sliding plate, a fixed plate, a rotating plate, a telescopic strip, a rotating groove structure, a rotating shaft, a blood collection needle tube, and a protective sleeve; the U-shaped sliding plate is slidably connected to the U-shaped sleeve; the fixed plate is fixedly connected to the U-shaped sliding plate; the rotating plate is rotatably connected to the fixed plate through a rotating shaft component; the telescopic strip is slidably connected inside the rotating plate; the telescopic strip has a rotating groove structure; the rotating shaft is detachably inserted into the telescopic rotating groove structure; the blood collection needle tube is fixedly connected to the rotating shaft; the protective sleeve is detachably inserted into the fixed plate; the blood collection needle tube is initially inserted into the protective sleeve.
[0005] As a further preferred option, the U-shaped jacket has several first ventilation slots; the U-shaped slide plate has several second ventilation slots.
[0006] As a further preferred option, the U-shaped sleeve is provided with several protrusion structures; a pressing piece is provided on the left and right sides of the U-shaped slide plate.
[0007] As a further preferred option, a wing is fixed to the blood collection needle.
[0008] As a further preferred option, a push plate is fixedly attached to the telescopic strip.
[0009] As a further preferred option, the rotating shaft, blood collection needle, and protective sleeve are disposable components.
[0010] As a further preferred option, the rotating groove structure is set as an arc-shaped slot structure with two-thirds of a circle, and the opening of the arc-shaped slot structure faces away from the fixed plate.
[0011] As a further preferred option, a torsion spring is fixedly connected between the rotating shaft components of the rotating plate and the fixed plate.
[0012] As a further preferred option, a pressure plate is fixed to the telescopic strip.
[0013] As a further preferred option, the pressure plate is provided with several protrusions, and the ends of the protrusions are non-sharp, flat-headed structures.
[0014] Beneficial Effects: This invention provides a newborn blood collection device for gene screening. It features a U-shaped clip and a U-shaped sliding plate, allowing it to replace manual gripping and be fitted onto the newborn's wrist. The U-shaped sliding plate is connected to a blood collection needle via a fixing plate, a rotating plate, a telescopic strip, and a rotating shaft. Even if the newborn struggles slightly, the blood collection needle, fixed to the U-shaped sliding plate, is unlikely to crush the newborn. Medical personnel only need to use both hands to control the telescopic strip and the blood collection needle to move along the rotating plate, inserting the needle into the newborn's blood vessel. This allows medical personnel to perform newborn blood collection independently and smoothly. If the newborn struggles violently, the medical personnel can quickly remove the rotating shaft to remove the blood collection needle, avoiding crushing the newborn. This invention solves the technical problems of medical personnel being unable to perform newborn blood collection independently and the discomfort caused by holding the newborn's wrist.

Detailed Implementation
[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0018] Example 1: A neonatal blood collection device for gene screening, as described in this example. Figures 1-5 As shown, it includes a U-shaped sleeve 1, a U-shaped sliding plate 2, a fixing plate 3, a rotating plate 41, a telescopic strip 42, a rotating groove structure 4201, a rotating shaft 43, a blood collection needle tube 44, a protective sleeve 45, a wing 46, and a pusher 47; the U-shaped sleeve 1 is slidably connected to the U-shaped sliding plate 2, as shown... Figure 1 As shown, the U-shaped slide plate 2 is initially completely merged with the outside of the U-shaped sleeve 1, with both the U-shaped sleeve 1 and the U-shaped slide plate 2 initially facing upwards; a fixing plate 3 is detachably fixed to the middle of the U-shaped slide plate 2; a rotating plate 41 is rotatably connected to the fixing plate 3 via a rotating shaft component; a telescopic strip 42 that slides and extends in the front-back direction is slidably connected inside the rotating plate 41; a rotating groove structure 4201 is provided at the end of the telescopic strip 42 away from the fixing plate 3; a rotating shaft 43 is detachably inserted into the telescopic rotating groove structure 4201; a fixed... A blood collection needle tube 44 is attached; a protective sleeve 45 is detachably inserted into the fixing plate 3; the blood collection needle tube 44 is initially inserted into the protective sleeve 45; a wing 46 is fixedly attached to the blood collection needle tube 44, and medical staff can hold the wing 46 and the blood collection needle tube 44 at the same time, which can increase the total contact area between the medical staff's fingers and the wing 46 and the blood collection needle tube 44, thereby controlling the blood collection needle tube 44 more flexibly; a pusher 47 is fixedly attached to the telescopic strip 42, and medical staff can more easily control the telescopic strip 42 to move along the rotating plate 41 by holding the pusher 47.
[0019] like Figure 1 and Figure 2As shown, the U-shaped sleeve 1 has several first ventilation grooves 101; the U-shaped slide plate 2 has several second ventilation grooves 201. When the U-shaped sleeve 1 and the U-shaped slide plate 2 are together placed on the newborn's wrist, the first ventilation grooves 101 on the U-shaped sleeve 1 and the second ventilation grooves 201 on the U-shaped slide plate 2 can enhance the breathability of the newborn's wrist skin and reduce the phenomenon of stuffiness and sweating. The U-shaped sleeve 1 has several protrusions 102 inside. The U-shaped sleeve 1 is placed on the newborn's wrist through the protrusions 102, with only the protrusions 102 present. 2. The U-shaped slide plate 2 has a pressure plate 202 on each of its left and right sides. After the U-shaped sleeve 1 and the U-shaped slide plate 2 are put on the newborn's wrist, during the newborn blood collection process, the medical staff can press the pressure plates 202 on both sides of the U-shaped slide plate 2 back and forth to push the protrusion structure 102 on both sides of the U-shaped sleeve 1 to squeeze the newborn's wrist, promote blood flow in the newborn's wrist, not only improve blood collection efficiency, but also allow normal blood circulation in the newborn's wrist.
[0020] Only the rotating shaft 43, blood collection needle 44, and protective sleeve 45 are disposable parts. The U-shaped clip 1, U-shaped slide plate 2, fixing plate 3, rotating plate 41, and telescopic strip 42 are all reusable medical-grade materials. Each time it is used, only the rotating shaft 43, blood collection needle 44, and protective sleeve 45 need to be replaced. Except for the rotating shaft 43, blood collection needle 44, and protective sleeve 45, the other materials do not come into contact with blood and only need to be disinfected, which reduces the waste of other materials.
[0021] Before using this newborn blood collection device for gene screening, medical staff connect the blood collection needle 44 to the blood collection container through the transfusion tube.
[0022] When using this newborn blood collection device for gene screening, medical staff first place the U-shaped clip 1 on the newborn's wrist, then rotate the U-shaped slide plate 2 to move it along the U-shaped clip 1 until... Figure 6In the shown setup, the U-shaped sleeve 1 and U-shaped slide 2 are together fitted onto the newborn's wrist, with the blood collection needle 44 aligned with the blood collection site on the newborn's wrist. Next, the medical staff pulls the pusher 47, causing the telescopic strip 42 to move forward along the rotating plate 41. The telescopic strip 42 pulls the rotating shaft 43, causing the blood collection needle 44 to be pulled out of the protective sleeve 45. The medical staff then flips the rotating plate 41 downwards, causing the telescopic strip 42, rotating shaft 43, and blood collection needle 44 to move closer to the blood collection site on the newborn's wrist. Then, one hand pushes the pusher 47, causing the telescopic strip 42 to move slowly backward along the rotating plate 41, while the other hand pushes the wing 46 and rotates the rotating shaft 43, causing the blood collection needle 44 to move. The needle is inserted into the blood collection site on the newborn's wrist. The blood collected from the blood collection site on the newborn's wrist flows along the blood collection needle 44 and the transfusion tube into the external blood collection container. Blood collection is performed on the newborn. Since the blood collection needle 44 is fixed to the newborn's wrist along with the U-shaped slide plate 2, even if the newborn struggles slightly, the blood collection needle 44 will move with the direction of the newborn's wrist swing. Therefore, the blood collection needle 44 fixed on the U-shaped slide is unlikely to crush the newborn. Medical staff only need to use both hands to control the telescopic bar 42 and the blood collection needle 44 to move along the rotating plate 41 and crush the blood collection needle 44 into the newborn's blood vessel. This allows medical staff to perform newborn blood collection smoothly and independently.
[0023] Example 2, as Figures 1-5 As shown, based on the above embodiment 1, the rotating groove structure 4201 of this embodiment is set as an arc-shaped slot structure with a two-thirds arc, and the opening of the arc-shaped slot structure faces away from the fixed plate 3. The rotating shaft 43 is locked in the arc-shaped slot structure. During the neonatal blood collection process, when the newborn struggles violently, the medical staff immediately pulls the wing 46 and the blood collection needle 44 to drive the rotating shaft 43 to be pulled upward quickly from the rotating groove structure 4201, so that the blood collection needle 44 is pulled away from the neonatal blood collection site along with the rotating shaft 43, so as to avoid the blood collection needle 44 damaging the neonatal blood collection site. At this time, the neonatal blood collection work is suspended, and priority is given to comforting the neonate who is struggling violently.
[0024] Example 3, as Figures 1-5As shown, based on the above embodiment 1, in this embodiment, a torsion spring 48 is fixedly connected between the rotating plate 41 and the rotating shaft component of the fixed plate 3. The torsion spring 48 is initially in a torsional state. A pressure plate 51 is fixedly connected to the telescopic bar 42. Under the action of the torsional torque, the torsion spring 48 drives the rotating plate 41, the telescopic bar 42, and the pressure plate 51 to rotate towards the U-shaped sleeve 1. The pressure plate 51 is provided with several protrusions 52, and the ends of the protrusions 52 are non-sharp flat structures. After the neonatal blood collection is completed, and after the medical staff removes the blood collection needle 44 and the rotating shaft 43 from the rotating groove structure 4201 of the telescopic bar 42, the medical staff rotates the rotating plate 41, the telescopic bar 42, and the pressure plate 51 away from the U-shaped sleeve 1, so that the rotating plate 41 drives the torsion spring 51 to rotate away from the U-shaped sleeve 1. As spring 48 twists, medical staff simultaneously clamp the medical hemostatic cotton between pressure plate 51 and the newborn's blood collection site. After the medical staff slowly releases pressure plate 51, the torsion spring 48 causes the rotating plate 41, telescopic strip 42, and pressure plate 51 to rotate towards the U-shaped clip 1, allowing pressure plate 51 to firmly clamp the medical hemostatic cotton onto the newborn's blood collection site. At the same time, the protrusions 52 on pressure plate 51 prevent the medical hemostatic cotton from falling off pressure plate 51. The ends of the protrusions 52 are non-sharp, flat-headed structures to avoid injuring the newborn's skin. In this way, the pressure plate 51 can replace manual maintenance to keep the medical hemostatic cotton tightly attached to the newborn's blood collection site. Before the wound at the newborn's blood collection site heals, medical staff can focus more on caring for the newborn.
