Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an easy-to-use sniffer needle holder. Background Technology

[0002] In medical blood collection scenarios, the lancet needle holder is a core auxiliary component in clinical blood collection operations, and its user experience directly affects blood collection efficiency, operational safety, and patient experience. Currently, most lancet needle holders on the market have structural design flaws, mainly manifested in insufficient tactile comfort and poor surface anti-slip performance.

[0003] In high-intensity blood collection scenarios such as peak outpatient visits and mass blood collection for physical examinations, medical staff need to hold the blood collection needle hub for extended periods of time to perform puncture procedures. Because existing needle hubs lack an ergonomic grip structure and have insufficient anti-slip surface design, medical staff must maintain a constant tension in their hands to ensure grip stability. Prolonged work can easily lead to occupational discomfort such as finger joint pain and palm muscle strain, resulting in decreased operational proficiency and slower blood collection speed, making it difficult to meet the efficiency requirements of high-intensity blood collection scenarios.

[0004] Meanwhile, insufficient anti-slip performance can cause slight slippage of the needle hub during gripping. Combined with decreased operational precision due to hand muscle fatigue, this may lead to inaccurate control of the puncture depth at the blood collection site. If the puncture is too deep, it may damage the patient's subcutaneous tissue, causing pain or bleeding; if the puncture is too shallow, it may not be possible to collect a sufficient amount of blood sample, requiring a second puncture, which not only increases the patient's pain and risk of infection, but also further reduces the overall efficiency of the blood collection process. Utility Model Content

[0005] This application provides a user-friendly snipping needle holder that solves the problems of poor tactile comfort and poor surface anti-slip properties of existing snipping needle holders.

[0006] This application provides a user-friendly bayonet blood collection needle holder, including a blood collection needle main tube, a hand-held mechanism mounted on the outer surface of the blood collection needle main tube, a force-bearing block fixedly mounted on the bottom end of the blood collection needle main tube, a plurality of anti-slip grooves formed on the outer surface of the force-bearing block, and the top end of the force-bearing block being fixedly connected to the bottom end of the blood collection needle main tube.

[0007] Furthermore, a needle mounting base is fixedly installed at the bottom end of the force-bearing block, and the top end of the needle mounting base is fixedly connected to the bottom end of the force-bearing block.

[0008] Furthermore, a flexible tube insertion block is fixedly installed at the top end of the blood collection needle main tube, and the bottom end of the flexible tube insertion block is fixedly connected to the top end of the blood collection needle main tube.

[0009] Furthermore, a miniature one-way valve is fixedly installed inside the main tube of the blood collection needle, and the miniature one-way valve is made of rubber.

[0010] Furthermore, the handheld mechanism includes two mounting slots, and a mounting plate is fixedly connected inside each mounting slot.

[0011] Furthermore, three anti-slip blocks are fixedly installed on the opposite sides of the two mounting plates, each of which is made of rubber.

[0012] Furthermore, two rubber anti-slip plates are fixedly installed on the side of each of the two mounting plates that are far apart from each other, and several anti-slip strips are fixedly installed on the side of each rubber anti-slip plate that is far away from the mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The technical solution provided in this application has at least the following technical effects or advantages:

[0015] The mounting plates fixed in the two mounting slots provide users with a force application point that conforms to their hand grip habits, avoiding the hand tension caused by the small diameter and lack of a force point when directly holding the main tube of the blood collection needle. The anti-slip block and rubber anti-slip plate not only increase the contact area between the hand and the hand-held mechanism, but also reduce the local pressure on the hand when holding it by utilizing the soft properties of the rubber material. In long-term continuous operation scenarios such as peak outpatient hours and batch blood collection for physical examinations, it can effectively avoid finger joint pain and palm strain caused by continuous tension of hand muscles, ensure the stability of the user's operation, maintain efficient operation speed, and solve the problems of poor hand comfort and poor surface anti-slip of existing bayonet blood collection needle holders.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Example 1:

[0023] Please see Figure 1-4 In this utility model, a user-friendly bayonet blood collection needle holder includes a blood collection needle main tube 1, a hand-held mechanism 2 installed on the outer surface of the blood collection needle main tube 1, a force-bearing block 3 fixedly installed at the bottom end of the blood collection needle main tube 1, and a plurality of anti-slip grooves 4 formed on the outer surface of the force-bearing block 3. The top end of the force-bearing block 3 is fixedly connected to the bottom end of the blood collection needle main tube 1. The force-bearing block 3 mainly undertakes the triple functions of connection, force application and anti-slip, realizing the stable connection between the blood collection needle main tube 1 and the needle mounting base 5, ensuring the continuity of blood flow path. The anti-slip grooves 4 increase the complexity of the texture of the force-bearing block 3 in contact with the hand and improve the friction.

[0024] Example 2:

[0025] A needle mounting base 5 is fixedly installed at the bottom of the force-bearing block 3. The top of the needle mounting base 5 is fixedly connected to the bottom of the force-bearing block 3. A tubing insertion block 6 is fixedly installed at the top of the blood collection needle main tube 1. The bottom of the tubing insertion block 6 is fixedly connected to the top of the blood collection needle main tube 1. A miniature one-way valve 7 is fixedly installed inside the blood collection needle main tube 1. The miniature one-way valve 7 is made of rubber. Its function is to realize one-way blood flow and prevent backflow. During blood collection, the blood can flow smoothly from one side of the force-bearing block 3 to the side of the tubing insertion block 6 under negative pressure and enter the blood collection tube.

[0026] The handheld mechanism 2 includes two mounting grooves 21, a mounting plate 22 is fixedly connected inside each mounting groove 21, three anti-slip blocks 23 are fixedly mounted on the sides of the two mounting plates 22 facing away from each other, each anti-slip block 23 is made of rubber, two rubber anti-slip plates 24 are fixedly mounted on the sides of the two mounting plates 22 facing away from each other, a plurality of anti-slip strips 25 are fixedly mounted on the side of each rubber anti-slip plate 24 facing away from the mounting groove 21. The anti-slip blocks 23 function to enhance gripping friction and improve comfort, the high friction coefficient of the rubber material can effectively prevent slipping between the hand and the mounting plate 22, and the effect is particularly remarkable when the hand is sweating. Meanwhile, the soft property of rubber can reduce the pressing sensation of the mounting plate 22 on the skin, relieve hand discomfort caused by long-time gripping, and further improve operation comfort. The rubber anti-slip plates 24 cooperate with the anti-slip blocks 23 to strengthen the anti-slip and comfort effects of the handheld mechanism 2, and the anti-slip strips 25 further increase the contact friction between the hand and the rubber anti-slip plates 24.

[0027] The working principle of the present application is as follows:

[0028] The user first aligns the blood collection needle with the needle mounting base 5 at the bottom end of the force-bearing block 3, completes the fixed connection between the needle and the base by means of rotation or snap-fitting, then inserts one end of the hose matched with the blood collection tube into the hose insertion block 6 at the top end of the blood collection needle main tube 1 to ensure that the hose is in internal communication with the blood collection needle main tube 1, thus completing the assembly work before blood collection. Next, the user holds the mounting plate 22 of the handheld mechanism 2 by hand, with fingers naturally fitting the anti-slip blocks 23 and the rubber anti-slip plates 24, and the palm fitting the force-bearing block 3. The anti-slip grooves 4 increase the friction between the hand and the force-bearing block 3 to stably grip the blood collection needle holder. After determining the blood collection site, the user applies appropriate force through the handheld mechanism 2 to puncture the blood collection needle into the blood collection site of the patient. At this time, blood enters the force-bearing block 3 through the needle under the action of negative pressure, and then flows into the blood collection needle main tube 1. Since the micro one-way valve 7 is installed inside the blood collection needle main tube 1, the blood will flow along the conduction direction of the one-way valve to the hose insertion block 6, and finally enter the blood collection tube. The one-way valve can effectively prevent the blood from flowing back reversely, avoiding blood contamination or affecting the blood collection effect. After the blood collection is completed, the user releases the handheld mechanism 2, pulls out the blood collection needle, then can detach the hose and the used needle in sequence, clean and disinfect the blood collection needle holder, or dispose of the discarded components in accordance with the medical waste disposal specifications, thus completing the entire blood collection process.

[0029] What has been described above is merely the preferred specific embodiment of the example of the present application, but the protection scope of the present application is not limited thereto. Any equivalent replacement or modification made by those skilled in the art within the technical scope disclosed by the present application based on the technical solution and the concept thereof of the present application shall be covered within the protection scope of the present application.
