Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a movable needle eye pressing device. Background Art

[0002] In clinical practice, after intravenous puncture such as drawing blood or removing an infusion needle, the needle hole often needs to be pressed by hand. If the pressure is not applied for a long enough time or the pressure is misplaced, it can easily lead to further bleeding. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the current method of pressing the needle hole after blood drawing or infusion is to use a handheld sterilized cotton swab stick for pressing, and manual pressing is prone to misalignment, causing bleeding again.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A movable needle eye pressing device comprises a wristband, the sides of which are close to each other are bonded by Velcro, a long waist hole is opened in the middle of the outer surface of the wristband, and a pressing device is detachably connected in the long waist hole;

[0006] The pressing device includes an inflation nozzle, an outer surface of the inflation nozzle located above the wristband is provided with an external thread, the outer surface of the inflation nozzle located above the wristband is also threadedly connected to a fixing knob, and one end of the inflation nozzle located below the wristband is also fixedly connected to an air bag connected to the interior thereof.

[0007] Furthermore, a notch is provided at the top of the inflation nozzle.

[0008] Furthermore, the cross-section of the airbag is hemispherical, and the wall thickness at the bottom is greater than the wall thickness at the side;

[0009] The distance from the middle of the bottom of the airbag to the horizontal plane increases successively to the distances from both sides thereof to the horizontal plane.

[0010] Furthermore, a timer alarm is fixedly connected to the outer surface of the wristband.

[0011] Working principle and beneficial effects: Insert the syringe into the fine hole of the one-way valve, inflate the airbag, and when it is inflated to the appropriate size, press it on the needle eye with a medical sterile infusion patch or a sterile cotton ball, and fix the wristband and bracelet together with Velcro. The relative position of the pressing device to the long waist hole can be adjusted by the tightness fixing knob, so that fine adjustments can be made after fixation, and it is also convenient to replace the pressing device to reduce material waste. The purpose of using the airbag to inflate and press is to facilitate the airbag to be replenished with air after the wristband is fixed on the wrist, so that the pressing is tighter.

[0015] The present invention can be better understood according to the following embodiments.

[0016] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0017] like Figure 1-2 As shown,

[0018] Example 1

[0019] A movable needle eye pressing device comprises a wristband bracelet 1, the sides of the wristband bracelet 1 close to each other are bonded by Velcro, a long waist hole 2 is opened in the middle of the outer surface of the wristband bracelet 1, and a pressing device is detachably connected in the long waist hole 2;

[0020] The pressing device includes an inflation nozzle 3, the outer surface of the inflation nozzle 3 is provided with an external thread at a position above the wristband bracelet 1, the outer surface of the inflation nozzle 3 is also threadedly connected to a fixing knob 4 at a position above the wristband bracelet 1, and the end of the inflation nozzle 3 located below the wristband bracelet 1 is also fixedly connected to an air bag 5 connected to the interior thereof.

[0021] The distance from the middle of the bottom of the airbag 5 to the horizontal plane increases successively to the distance from both sides thereof to the horizontal plane. The cross section of the airbag 5 is hemispherical, and the wall thickness of the bottom is greater than the wall thickness of the side. After being inflated, the bottom remains a convex arc surface to ensure the pressing effect.

[0022] The inflation nozzle 3 is also embedded with a rubber one-way valve, which can be pre-inserted into the fine hole of the one-way valve through a syringe to inflate the airbag 5. When it is inflated to an appropriate size, it is pressed on the needle eye with a medical sterile infusion patch or a sterile cotton ball, and the ends of the wristband bracelet 1 that are close to each other are fixed with Velcro. The relative position of the pressing device at the long waist hole 2 can be adjusted by the loose fixing knob 4, so that fine adjustments can be made after fixation, and it is also convenient to replace the pressing device to reduce material waste. The purpose of inflating and pressing the airbag 5 is to facilitate the replenishment of air to the airbag 5 after the wristband is fixed on the wrist, so that the pressing is tighter.

[0023] In order to prevent the inflation nozzle 3 from rotating when the fixing knob 4 is rotated, embodiment 2 is provided. The specific structure is that a notch 6 is also provided on the top of the inflation nozzle 3. The thumb nail or other instruments can be used to get stuck in the notch 6 to prevent the inflation nozzle 3 from rotating together with the fixing knob 4.

[0024] In embodiment 3, a timer alarm 7 is fixedly connected to the outer surface of the wristband bracelet 1, and the time can be set by the timer alarm 7 to alarm at regular intervals.
