Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a heel blood smear clamping device. Background Technology

[0002] Newborns need to be screened for congenital metabolic disorders, endocrine disorders, and deafness genes after birth. Current screening methods typically involve pricking the newborn's heel to collect blood for disease screening. Heel prick blood collection is usually performed 72 hours to 7 days after birth, after adequate feeding (up to 20 days for premature infants). During the procedure, the newborn's sole needs to be firmly grasped and squeezed. Applying warmth before the procedure can improve the efficiency of natural bleeding.

[0003] After pricking the newborn's heel, the blood should be dripped onto a blood smear and allowed to air dry naturally (3-4 hours). Then, the smear should be placed in a sealed bag and refrigerated. It should be sent to a higher-level institution within the prescribed time and then sent to a testing institution for analysis.

[0004] During bedside blood collection, medical staff place a heel prick blood smear holder on a treatment cart and move the cart to different beds to collect blood from newborns. For example, when blood needs to be collected from a newborn in one bed, the medical staff will push the cart to that bed and collect blood using a heel prick blood smear. After collection, the medical staff will clamp the collected heel prick blood smear onto the holder on the treatment cart and move the cart to the next bed to collect blood from the newborn there.

[0005] During outpatient blood collection, medical staff will collect blood from different newborns and clamp the collected heel prick blood smears onto a heel prick blood smear holder. After the outpatient blood collection is completed, the medical staff will place the heel prick blood smear holder onto a treatment cart and push the cart back to the ward.

[0006] In all the aforementioned blood collection processes, the heel prick blood smear holding device needs to be moved along with the treatment cart. However, existing heel prick blood smear holding devices cannot hold the heel prick blood smears well. As the heel prick blood smears move along the treatment cart, they easily fall off the holding device, causing contamination of the blood smears and affecting the accuracy of subsequent test results.

[0007] Therefore, there is an urgent need for a heel prickling device that can effectively hold heel pricklings. Utility Model Content

[0085] According to one embodiment of the present invention, referring to... Figure 3 The locking block 9 has a locking hole 10, and the locking hole 10 is close to one end of the locking rod 11 near the locking block 9 (i.e., Figure 3 The leftmost end of the locking rod 11 is adapted to the locking block 9. When the clamp 3 holds the heel blood patch, the locking rod 11 extends into the locking hole 10 to lock the locking block 9 and the clamp 3 above.

[0086] In this embodiment, refer to Figure 6 The locking hole 10 can be a cylindrical structure.

[0087] In this embodiment, refer to Figure 3 The locking hole 10 can completely penetrate the locking block 9.

[0114] In this embodiment, refer to Figure 3 The two ends of the third spring 23 can abut against the right side wall of the fourth connecting block 21 and the left side wall of the vertical plate 2 respectively, or they can be fixedly connected to both, without any particular limitation.

[0115] According to one embodiment of the present invention, referring to... Figure 1 and Figure 5 The fixing mechanism includes a suction cup housing 24 installed at the bottom of the base plate 1, and the bottom of the suction cup housing 24 has an open structure.

[0116] In this embodiment, refer to Figure 1 and Figure 5 The suction cup housing 24 can be a frustum structure.

[0117] According to one embodiment of the present invention, referring to... Figure 1 and Figure 5 A suction unit is installed on the base plate 1. One end of the suction unit located below the base plate 1 is located inside the suction cup housing 24, and the suction cup body 25 is fixedly installed at the bottom end of the suction unit. The top end of the suction cup body 25 abuts against the bottom end of the suction cup housing 24. The suction unit is used to make the suction cup body 25 suction.

[0118] Furthermore, referring to Figure 1 and Figure 5 The suction unit includes a movable rod 26 that is slidably mounted on the base plate 1 in a vertical direction. One end of the movable rod 26 located below the base plate 1 is inside the suction cup housing 24, and the bottom end of the movable rod 26 is fixedly connected to the center of the suction cup body 25.

[0119] In this embodiment, the suction cup body 25 can be made of rubber materials known in the art, such as nitrile rubber and polyurethane. The suction cup outer shell 24 can be made of hard plastic materials known in the art.

[0120] In this embodiment, refer to Figure 5 The movable rod 26 can penetrate the base plate 1 vertically and slide in engagement with the base plate 1. The fixed connection between the movable rod 26 and the suction cup body 25 can be any method known in the art, such as bonding with adhesive substances, and is not particularly limited here.

[0121] According to one embodiment of the present invention, referring to... Figure 4 and Figure 5 The movable rod 26 is rotatably mounted with a buckle 27 at one end located above the base plate 1, and the bottom end of the buckle 27 contacts and engages with the top end of the base plate 1.

[0122] In this embodiment, the rotatable connection between the movable rod 26 and the buckle 27 can be achieved by using a bearing known in the art, or by setting a rotating shaft between the two for rotatable connection, without any particular limitation.

[0123] According to one embodiment of the present invention, the buckle 27 has an arc-shaped protrusion on the side wall of the end near the base plate 1.

[0124] In this embodiment, refer to Figure 5 The structure of buckle 27 can be a structure similar to the letter "b".

[0125] In one embodiment of this utility model, reference is made to Figure 5 Because the buckle 27 has an arc-shaped protrusion, when it is... Figure 5 When the latch 27 is rotated clockwise, the latch 27 will pull the moving rod 26 upward under the action of the arc-shaped protrusion. The moving rod 26 will then pull the suction cup body 25 upward, thereby allowing the suction cup body 25 to be firmly attached to an external platform (such as a desktop) to secure the device using atmospheric pressure. That is, when the arc-shaped protrusion contacts the top of the base plate 1, the moving rod 26 will hold the suction cup body 25 firmly in place.

[0126] When it is necessary to remove the device from the external platform, rotate the latch 27 in the opposite direction. At this time, the moving rod 26 will move downward, thereby canceling the upward pull on the suction cup body 25, so that the device can be easily removed from the external platform.

[0127] According to one embodiment of the present invention, a buffer anti-slip layer (not shown in the figure) is installed at the bottom end of the upper clamping plate 3 and the top end of the lower clamping plate 3 in the clamping mechanism.

[0128] In this embodiment, the cushioning and anti-slip layer can be made of materials known in the art, such as silicone, and is not particularly limited thereto. The cushioning and anti-slip layer allows the clamping plate 3 to more firmly hold the heel pouch.

[0129] In this embodiment, both the second telescopic rod 18 and the third telescopic rod 22 can be structures in which the slider is sleeved inside the sleeve. When the slider rises to the top of the sleeve, it will be limited by the top of the inner wall of the sleeve, thus preventing the slider from sliding out of the top of the sleeve (as is known in the art). Those skilled in the art can also choose any telescopic rod known in the art and suitable for this device according to the actual situation, without any particular limitation.

[0130] The working process of this device will be briefly described below with reference to the above embodiments:

[0131] When it is necessary to clamp the heel pouches, firstly, place multiple heel pouches sequentially between the two clamping plates 3 above and below the clamping mechanism of different layers, and then press down on the upper clamping plate 3. At this time, refer to Figure 3 The upper clamp 3 will move downwards to clamp the blood clots on the heel.

[0132] The downward movement of the upper clamping plate 3 will cause the locking block 9 to move downward synchronously until the locking hole 10 moves to the same position as the locking rod 11. At this point, the locking rod 11 will be inserted into the locking hole 10 under the pulling force of the tension spring 13 (see reference). Figure 9 This locks the upper clamp 3 and continuously clamps the blood clots on the heel.

[0133] Then, refer to Figure 9 When multiple heel pouches need to be removed simultaneously from the clamping plates 3 of different layers of clamping mechanisms, i.e., when the upper clamping plates 3 of different layers of clamping mechanisms need to be unlocked, the unlocking lever 16 is pulled to the right. The rightward movement of the unlocking lever 16 will cause the fourth connecting block 21 to move to the right and compress the third telescopic lever 22 and the third spring 23. At the same time, it will also cause the second telescopic lever 18 to move to the right. Since the telescopic end of the second telescopic lever 18 is located in the unlocking hole 14 at this time, the rightward movement of the second telescopic lever 18 will cause the locking lever 11 to move to the right until the locking lever 11 is completely disengaged from the locking hole 10. At this time, the upper clamping plate 3 will automatically move upward under the elastic force of the first spring 8, thereby releasing the clamping of the heel pouches and allowing them to be removed.

[0134] Since the unlocking levers 16 of each layer are connected, pulling the unlocking lever 16 to the right once can simultaneously remove the heel blood patches from different layers, thus improving the efficiency of removing the heel blood patches.

[0135] When the upper clamp 3 returns to its original position, release the unlocking lever 16. The unlocking lever 16 will automatically return to its original position under the elastic force of the third spring 23 (i.e., towards). Figure 9 (Moves to the left). Because the top of the telescopic end of the second telescopic rod 18 has a sloping structure, when the unlocking rod 16 moves to the left, and when the ball bearing 15 re-abuts against the right side wall of the locking block 9 (i.e., after the upper clamping plate 3 returns to its original position), the telescopic end of the second telescopic rod 18 will automatically press down on the second spring 19 due to its sloping structure. This causes the telescopic end of the second telescopic rod 18 to automatically retract, allowing the unlocking mechanism to automatically return to its original position. Figure 3 Position it in the middle to prepare for the next clamping operation.

[0136] Furthermore, if it is not necessary to remove every layer of heel prick blood, but only a single layer of heel prick blood needs to be removed, then refer to... Figure 9Simply pull the locking lever 11 to the right until it is completely disengaged from the locking hole 10, and you can remove a single layer of heel pouches. Pulling the locking lever 11 to the right on a single layer will not cause the unlocking lever 16 to move synchronously, preventing each layer of heel pouches from falling off, as the spring force of the third spring 23 keeps the unlocking lever 16 relatively stationary. Simultaneously, due to the inclined structure of the telescopic end of the second telescopic lever 18, when the locking lever 11 is pulled to the right, the telescopic end of the second telescopic lever 18 automatically retracts downwards as the locking lever 11 moves to the right, returning to its abutting state with the bottom of the locking lever 11, thus allowing the removal of a single layer of heel pouches.

[0137] The above embodiments of this utility model can be combined with each other and have corresponding technical effects.

[0138] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
