Description

Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to a sampler for heparin sodium products. Background Technology

[0002] Heparin sodium is an anticoagulant that interferes with many aspects of the blood clotting process. It has anticoagulant effects both in vivo and in vitro. When sampling heparin sodium, blood samples need to be drawn.

[0003] Conventional blood collection tubes require inserting a needle into a vein and then connecting it to a blood collection tube with negative pressure to draw blood. Because this requires two separate operations, the operation of conventional heparin sodium product samplers is quite cumbersome.

[0004] To address this issue, we propose a heparin sodium product sampler. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional heparin sodium product samplers are relatively cumbersome to operate, and to propose a heparin sodium product sampler.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heparin sodium product sampler includes a needle, a needle hub, a negative pressure bottle, and a sealing cap. The upper part of the needle is fitted over the lower part of the needle hub, and the internal space of the needle is in communication with the internal space of the needle hub. The needle hub is clamped to the outside of the negative pressure bottle, and the sealing cap is rotatably fitted over the lower part of the negative pressure bottle, fitting snugly to the lower end of the negative pressure bottle. In use, the index and middle fingers are held outside the needle hub, and then the needle hub is operated to insert the needle into a vein. The thumb is then used to press the negative pressure bottle, causing the lower part of the bottle to be pierced by the needle hub, thus creating communication between the internal space of the needle and the internal space of the negative pressure bottle. The negative pressure inside the bottle is used to draw blood from the vein, facilitating the collection of heparin sodium samples.

[0008] Preferably, the needle holder includes a base and a tubular needle tip, the tubular needle tip being fixedly connected to the lower part of the base and penetrating through the base. When the thumb presses on the negative pressure bottle, the negative pressure bottle moves downward along the base, causing the upper end of the tubular needle tip to pierce the lower part of the negative pressure bottle, thus connecting the internal space of the tubular needle tip with the internal space of the negative pressure bottle, facilitating connection between the needle holder and the internal space of the negative pressure bottle.

[0009] Preferably, the needle holder further includes a pinch button, which is symmetrically and fixedly connected to the upper outer end of the holder body. The pinch button allows the index and middle fingers to easily grip the holder body.

[0010] Preferably, the needle hub further includes a connecting nozzle, which is fixedly connected to the lower end of the tubular needle tip, and the tubular needle tip and the connecting nozzle are an integral structure. The connecting nozzle facilitates the connection between the needle hub and the needle tip.

[0011] Preferably, the negative pressure bottle includes a bottle body and a dome-shaped nozzle, the dome-shaped nozzle being fixedly connected to the lower part of the bottle body, and the bottle body and the dome-shaped nozzle being an integral structure. When the bottle body is subjected to downward pressure, it moves downward along the base, squeezing the dome-shaped nozzle downward, causing the dome-shaped nozzle to squeeze the tubular needle tip, thereby piercing the dome-shaped nozzle. This allows the negative pressure inside the bottle body and the dome-shaped nozzle to act on the needle holder, facilitating sampling by the negative pressure bottle.

[0012] Preferably, the negative pressure bottle further includes a widening plate, which is fixedly connected to the upper end of the bottle body. The widening plate increases the contact area between the negative pressure bottle and the thumb, reduces the pressure between the thumb and the bottle, and improves the comfort of pressing the negative pressure bottle.

[0013] Preferably, the sealing cap includes a cap body, a plastic sheet, and a plastic ring, with the cap body and plastic ring fixedly connected to both ends of the plastic sheet. The cap body is secured to the negative pressure bottle by the plastic sheet and plastic ring to prevent it from falling off.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. When using, place your index and middle fingers on the outside of the needle holder, then operate the needle holder to insert the needle into the vein. Then, press the negative pressure bottle with your thumb to pierce the lower part of the negative pressure bottle with the needle holder, so that the internal space of the needle is connected to the internal space of the negative pressure bottle. Use the negative pressure inside the negative pressure bottle to draw blood from the vein, which is convenient for drawing heparin sodium.

[0016] 2. After pressing the thumb on the negative pressure bottle, move the negative pressure bottle downward along the base, so that the upper end of the tubular needle tip pierces the lower part of the negative pressure bottle, making the internal space of the tubular needle tip communicate with the internal space of the negative pressure bottle, which facilitates connecting the needle base and the internal space of the negative pressure bottle.

[0017] 3. When the bottle is subjected to downward pressure, it moves downward along the base. The bottle squeezes the cover-shaped nozzle downward, which in turn squeezes the tubular needle tip. This causes the tubular needle tip to pierce the cover-shaped nozzle, and the negative pressure inside the bottle and the cover-shaped nozzle acts on the needle holder, facilitating the negative pressure bottle to collect samples.

[0018] 4. The widened plate increases the contact area between the negative pressure bottle and the thumb, reduces the pressure between the thumb and the negative pressure bottle, and improves the comfort of pressing the negative pressure bottle. Attached Figure Description

[0024] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0025] Reference Figure 1 and 2 A heparin sodium product sampler includes a needle 1, a needle holder 2, a negative pressure bottle 3, and a sealing cap 4. The upper part of the needle 1 is fitted onto the lower part of the needle holder 2, and the internal space of the needle 1 is connected to the internal space of the needle holder 2. The needle holder 2 is clamped onto the outside of the negative pressure bottle 3. The sealing cap 4 is rotatably fitted onto the lower part of the negative pressure bottle 3, and the sealing cap 4 is matched with the lower end cap of the negative pressure bottle 3.

[0026] Reference Figure 1 and 2 The needle holder 2 includes a base 21 and a tubular needle tip 22. The tubular needle tip 22 is fixedly connected to the lower part of the base 21 and penetrates through the base 21. When the thumb presses on the negative pressure bottle 3, the negative pressure bottle 3 moves downward along the base 21, thereby causing the upper end of the tubular needle tip 22 to pierce through the lower part of the negative pressure bottle 3, making the internal space of the tubular needle tip 22 communicate with the internal space of the negative pressure bottle 3.

[0027] Reference Figure 1 and 2 The needle holder 2 also includes a pinch button 24, which is symmetrically and fixedly connected to the upper outer end of the base body 21. The pinch button 24 is used to hold the base body 21 with the index and middle fingers.

[0028] Reference Figure 1 and 2 The needle holder 2 also includes a mating nozzle 23, which is fixedly connected to the lower end of the tubular needle tip 22, and the tubular needle tip 22 and the mating nozzle 23 are an integral structure. The mating nozzle 23 is used to mate with the needle tip 1.

[0029] Reference Figure 1 , 2 The negative pressure bottle 3 includes a bottle body 32 and a dome-shaped nozzle 33. The lower end of the dome-shaped nozzle 33 is directly opposite the upper end of the tubular needle tip 22. The bottle body 32 is clamped inside the base 21, and the dome-shaped nozzle 33 is fixedly connected to the lower part of the bottle body 32. The bottle body 32 and the dome-shaped nozzle 33 are an integral structure. When the bottle body 32 is subjected to downward pressure, it moves downward along the base 21. The bottle body 32 presses down on the dome-shaped nozzle 33, which in turn presses down on the tubular needle tip 22, causing the tubular needle tip 22 to pierce the dome-shaped nozzle 33. This causes the negative pressure inside the bottle body 32 and the dome-shaped nozzle 33 to act on the needle holder 2.

[0030] Reference Figure 1 and 3 The negative pressure bottle 3 also includes a widening plate 31, which is fixedly connected to the upper end of the bottle body 32. The widening plate 31 increases the contact area between the negative pressure bottle 3 and the thumb, thereby reducing the pressure between the thumb and the negative pressure bottle 3.

[0031] Reference Figure 1 , 3 4. The sealing cap 4 includes a cap body 41, a plastic sheet 42, and a plastic ring 43. The plastic ring 43 is rotatably fitted between the dome-shaped bottle mouth 33 and the bottle body 32. The cap body 41 is fitted and matched with the dome-shaped bottle mouth 33. The cap body 41 and the plastic ring 43 are fixedly connected to both ends of the plastic sheet 42. The cap body 41 is secured to the negative pressure bottle 3 by the plastic sheet 42 and the plastic ring 43.

[0032] Working principle: When the thumb presses on the negative pressure bottle 3, the negative pressure bottle 3 moves downward along the base 21, so that the upper end of the tubular needle tip 22 pierces the lower part of the negative pressure bottle 3, making the internal space of the tubular needle tip 22 communicate with the internal space of the negative pressure bottle 3. Blood is drawn for sampling using negative pressure. After sampling is completed, the negative pressure bottle 3 is pulled out, and then the sealing cap 4 is placed on the bottom of the negative pressure bottle 3.
