Description

Technical Field

[0001] This utility model relates to the field of blood collection protection equipment, specifically a nail protector. Background Technology

[0002] Finger-prick blood glucose testing is a common method for monitoring blood glucose levels and usually provides relatively accurate readings. This test is simple and quick, suitable for daily blood glucose monitoring by diabetic patients. Common factors affecting accuracy during finger-prick blood collection include the technique used, the cleanliness of the puncture site, and the accuracy of the puncture device. For example, using a blood glucose meter with glucose oxidase or hexokinase reagents can reduce the influence of interfering substances and improve accuracy. Furthermore, ensuring the cleanliness and single-use of the lancet, and cleaning the finger before puncture, can reduce contamination and errors. In some cases, such as when using certain medications, blood glucose levels may be affected by the medication; medication and monitoring frequency should be adjusted under the guidance of a doctor.

[0003] However, the following problems still exist when performing finger prick blood sampling on diabetic patients:

[0004] The needles used for finger prick blood collection are small and generally invisible to the naked eye after pricking the finger. This can lead to frequent pricking of the same spot on the same finger. If the procedure is not performed correctly, it may cause local skin damage, increase the risk of infection, and cause more pain. Therefore, it is necessary to use nail protectors in the field of existing blood collection protective equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, the needles used for finger prick blood collection are relatively small, and the prick is generally invisible to the naked eye. This leads to frequent pricking of the same spot on the same finger. If the operation is not performed properly, it may cause local skin damage, increase the risk of infection, and cause more pain. This invention proposes a nail protector.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a nail protector, including a rubber finger sleeve, one end of which is fixedly equipped with a plastic connecting plate, and a finger placement groove is provided on the rubber finger sleeve. The other end of the rubber finger sleeve is fixedly equipped with an elastic band, which is located outside the finger placement groove. The plastic connecting plate is provided with an operating port, and the operating port is provided with multiple needle insertion ports, which are connected to the finger placement groove. Guide rods are symmetrically fixedly equipped on the operating port, and the guide rods are located on one side of the multiple needle insertion ports. A positioning and stabilizing mechanism is equipped on the guide rods.

[0007] Preferably, the positioning and stabilizing mechanism includes a positioning mark block, two guide rods are movably assembled with the positioning mark block, and a positioning pointer is fixedly mounted on the positioning mark block, with the positioning pointer close to the pin port.

[0008] Preferably, the inner wall of the operating port is provided with multiple slots, the number of which is the same as the number of pin ports.

[0009] Preferably, a connecting block is fixedly mounted on one end of the positioning mark block, a first horizontal block is fixedly mounted on the side of the connecting block, a second horizontal block is fixedly mounted on the side of the connecting block, the second horizontal block is located below the first horizontal block, and a traction port is provided through the second horizontal block.

[0010] Preferably, connecting rods are symmetrically fixedly mounted on the traction port, and operating blocks are movably mounted on the two connecting rods. A fixing plate is fixedly mounted on the top of the operating block, and a positioning rod is fixedly mounted on the operating block. The positioning rod is located below the second horizontal block, and the positioning rod is inserted into the slot on the operating port.

[0011] Preferably, an installation tube is fixedly mounted on the second cross block. The installation tube is located on one side of the traction port and has a movable port that communicates with the interior of the installation tube.

[0015] The advantages of this utility model are:

[0016] This invention requires inserting the finger to be drawn into the finger placement groove of a rubber finger cot. The elasticity of the rubber band secures the finger within the cot, causing the fingertip to be pulled out of the puncture site, preventing blood from adhering to the cot during blood collection. Positioning pointers on the positioning block sequentially point to the fingertip of the finger pulled out of the puncture site, indicating the previous puncture location. Another finger presses the lever, positioning the finger within the U-shaped stop. The telescopic spring extends and retracts, causing the lever to move the mounting plate on the sliding block. The operating block moves on the connecting rod under the action of the adjusting rod. The operating block drives the positioning rod to insert into the slot on the operating port, increasing the stability between the positioning mark block and the plastic connecting plate. The finger pushes the U-shaped stop, which prevents the finger from sliding out on the pressing rod, causing the positioning mark block to move on the guide rod. By modifying the position of the positioning mark block on the guide rod, the position of the needle insertion point on the patient can be changed, avoiding frequent punctures of the same finger at the same location, improving the operation effect, and reducing local skin damage and infection risk.

Guide rods 22 are symmetrically fixedly mounted on the operating port 13, located on one side of the pin insertion ports 21. A positioning and stabilizing mechanism is mounted on the guide rods 22, including two positioning marker blocks 23. The guide rod 22 is movably assembled with the positioning mark block 23. A positioning pointer 32 is fixedly mounted on the positioning mark block 23. The positioning pointer 32 is close to the needle insertion port 21. The inner wall of the operating port 13 is provided with multiple slots 30. The number of slots 30 is the same as the number of needle insertion ports 21. The positioning mark block 23 moves on the guide rod 22 so that the positioning pointer 32 on the positioning mark block 23 points to the needle insertion port 21 in turn, which is convenient to remind the patient of the last needle insertion point. By modifying the position of the positioning mark block 23 on the guide rod 22, the position of the patient's needle insertion point can be changed, avoiding frequent punctures of the same part of the same finger and improving the operation effect.

[0033] Reference Figure 3 and Figure 4A connecting block 33 is fixedly mounted on one end of the positioning mark block 23. A first horizontal block 40 is fixedly mounted on the side of the connecting block 33. A second horizontal block 41 is fixedly mounted on the side of the connecting block 33. The second horizontal block 41 is located below the first horizontal block 40. A traction port 42 is provided through the second horizontal block 41. Connecting rods 43 are symmetrically fixedly mounted on the traction port 42. An operating block 50 is movably mounted on the two connecting rods 43. A fixing plate 51 is fixedly mounted on the top of the operating block 50. A positioning rod 60 is fixedly mounted on the operating block 50. The positioning rod 60 is located below the second horizontal block 41 and is inserted into the slot 30 on the operating port 13. An installation tube 53 is fixedly mounted on the second horizontal block 41. The installation tube 53 is located on one side of the traction port 42.

[0034] The mounting tube 53 is provided with a movable port 71 that communicates with the interior of the mounting tube 53. A pressing rod 61 is movably mounted on the mounting tube 53, passing through the mounting tube 53 and the first horizontal block 40. A sliding block 72 that moves in the movable port 71 is fixedly mounted on the pressing rod 61. A mounting plate 20 is fixedly mounted on one end of the sliding block 72.

[0035] During use, the finger to be drawn needs to be inserted into the finger placement groove 31 of the rubber finger sleeve 11. Under the elastic force of the rubber band 12, the finger to be drawn is clamped in the rubber finger sleeve 11, and the fingertip of the finger is pulled out from the needle insertion port 21, preventing blood from adhering to the rubber finger sleeve 11 during blood collection. The positioning pointer 32 on the positioning mark block 23 points sequentially to the fingertip of the finger pulled out from the needle insertion port 21, which helps to remind the patient of the last needle insertion site. Press the pressing rod 61 with another finger, so that the finger is in the U-shaped stop block 62. The telescopic spring 70 extends and retracts, and the pressing rod 61 drives the mounting plate 20 on the sliding block 72 to move. Under the action of the adjusting rod 52, the operating block 50 moves on the connecting rod 43. The operating block 50 drives the positioning rod 60 to insert into the slot 30 on the operating port 13, increasing the stability between the positioning mark block 23 and the plastic connecting plate 10. The finger pushes the U-shaped stop 62, which restricts the finger from sliding out on the pressing rod 61, causing the positioning mark block 23 to move on the guide rod 22. By modifying the position of the positioning mark block 23 on the guide rod 22, the position of the needle insertion point of the patient is changed, avoiding frequent punctures of the same finger at the same location, improving the operation effect, and reducing local skin damage and infection risk.
