Description

Technical Field

[0001] The utility model relates to the technical field of blood vessel puncture, in particular to a compression device that is convenient for observing the blood vessel puncture point of a newborn. Background Art

[0002] When puncturing a neonatal artery or vein, strict aseptic techniques must be followed to prevent infection. If dark blood is drawn, indicating that the needle has entered a vein, it should be removed immediately. Pressure should be applied to the puncture site for 3-5 minutes, and proper pressure should be applied after the puncture to stop bleeding and prevent local thrombosis. Therefore, the wound should be observed for a short period of time during and after the puncture to ensure that the procedure was performed properly.

[0003] The vascular puncture visualization device is a device used to apply pressure to stop bleeding and observe the condition of the puncture point.

[0004] When used on adults, the pressure adjustment part of the existing vascular puncture visualization instrument can relatively meet the puncture compression requirements. However, when performing vascular puncture on newborns, the pressure adjustment is difficult to adapt to the newborn's tolerance range, which can easily cause excessive compression, leading to adverse conditions such as blood loss in the newborn's affected limb. Utility Model Content

[0005] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present invention is to provide a compression device that is convenient for observing the puncture point of the newborn's blood vessels, and adjusts the pressure in a slow and self-adjusting manner to avoid excessive compression of the newborn's affected limb due to long-term compression.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a compression device for facilitating observation of the puncture point of a neonatal blood vessel, comprising a compression device and a strap, the compression device comprising a compression strip and a rubber pad, the compression strip having a first through slot, a second through slot, and two through holes respectively formed at both ends, the two through holes being symmetrically arranged on one side of the second through slot, a first compression buckle being fixed on the rubber pad, the first compression buckle passing through the through holes;

[0007] One end of the strap is provided with a widening head, and the strap is embedded in the through slot 1 with the widening head. The end of the strap away from the widening head passes through the through slot 2, and then passes through the gap between the pressure buckle 1 and the compression strip.

[0008] Furthermore, a second pressure buckle is provided on the compression strip, and one end of the strap passes through the gap between the first pressure buckle and the compression strip and is folded in the opposite direction.

[0009] Furthermore, a soft pad is provided on one side of the strap close to the compression strip.

[0010] Furthermore, it includes a pressure regulating part, which includes a transparent bolt. The compression bar is provided with a threaded tube, the threaded tube passes through the compression bar, and the transparent bolt is engaged in the threaded tube.

[0011] Furthermore, a widened boss 1 is provided at one end of the transparent bolt away from the strap, and an observation port is provided at one end of the widened boss 1 away from the strap.

[0012] Furthermore, the pressure regulating part includes a dust cover, an annular protrusion is provided at the edge of the dust cover, and a retaining ring is provided on the inner side of the annular protrusion of the dust cover, and the transparent bolt is provided with a widened boss 2 at one end close to the strap, and a retaining groove is provided at the edge of the widened boss 2, and the dust cover is connected to the transparent bolt in such a way that the retaining ring is embedded in the retaining groove.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] 1. The newborn's affected limb is passed through the compression device and the strap. By pulling the end of the strap that passes through the pressure buckle 2, the space between the compression device and the strap can be narrowed, so that the vascular puncture visualization instrument can be stably worn on the newborn's affected limb. At this time, the pressure buckle 1 is lifted by the strap to loosen the strap, and the rubber pad is deformed to facilitate tightening the strap. After the strap is tightened, the rubber pad recovers, which drives the pressure buckle 1 to press the strap on the compression strip, and the contact part between the strap and the pressure buckle 1 is deformed and concave, so that the strap is stably compressed on the compression strip, so that the vascular puncture visualization instrument can be stably worn.

[0015] 2. After the vascular puncture visualization device can be worn on the neonatal affected limb, remove the tension on the band. If the vascular puncture visualization device is too surgically applied, the rebound force of the neonatal affected limb will gradually expand the space between the compression device and the band, thus preventing the compression device and the band from exerting excessive pressure on the neonatal affected limb.

[0016] 3. After wearing the vascular puncture visualizer, remove the dust cover and turn the transparent bolt to control the widened boss to press on the puncture point to stop bleeding. The puncture point can be observed intuitively through the observation port, and the condition of the puncture point can be confirmed in real time to avoid adverse situations.

[0038] See also Figure 1-5 The utility model provides a technical solution: a compression device for facilitating observation of vascular puncture points in newborns, comprising a pressure regulating part 1, a compression device 2 and a band 3.

[0039] The voltage regulating part 1 includes a transparent bolt 11 and a dust cover 12 .

[0040] One end of the transparent bolt 11 is provided with a widened boss 111, and the end of the widened boss 111 away from the transparent bolt 11 is provided with an observation port 1110. The end of the transparent bolt 11 away from the widened boss 111 is provided with a widened boss 2 112, and a slot 1120 is provided at the edge of the widened boss 2 112.

[0041] An annular protrusion is provided at the edge of the dust cover 12 , and a snap ring 121 is provided on the inner side of the annular protrusion of the dust cover 12 .

[0042] The dust cover 12 is connected to the transparent bolt 11 in a manner that the snap ring 121 is engaged in the snap groove 1120 .

[0043] The compression device 2 includes a compression strip 21 and a rubber pad 22 .

[0044] The two ends of the compression strip 21 are respectively provided with a through groove 1 2101, a through groove 2102 and two through holes 2103. The two through holes 2103 are symmetrically arranged on one side of the through groove 2102. The compression strip 21 is provided with a threaded tube 211 and a pressure buckle 2 212. The threaded tube 211 passes through the compression strip 21.

[0045] The transparent bolt 11 is engaged in the threaded tube 211 .

[0046] A belt buckle 221 is fixed on the rubber pad 22 , and the belt buckle 221 passes through the through hole 2103 .

[0047] One end of the strap 3 is provided with a widening head 31, and the strap 3 is embedded in the through slot 1 2101 with the widening head 31. The end of the strap 3 away from the widening head 31 passes through the through slot 2 2102, and then passes through the gap between the self-pressing buckle 1 221 and the compression strip 21.

[0048] One end of the strap 3 that passes through the gap between the first pressure buckle 221 and the compression strip 21 passes through the gap between the second pressure buckle 212 and the compression strip 21 and is folded in the opposite direction.

[0049] A soft pad 32 is provided on one side of the strap 3 close to the compression strip 21 .

[0050] The newborn's affected limb is passed through the compression device 2 and the strap 3, and the space between the compression device 2 and the strap 3 can be narrowed by pulling the end of the strap 3 passing through the pressure strap buckle 212, so that the vascular puncture visualization instrument can be stably worn on the newborn's affected limb. At this time, the pressure strap buckle 1 221 is lifted by the strap 3 to loosen the strap 3, and the rubber pad 22 is deformed to facilitate tightening the strap 3.

[0051] In addition, after the vascular puncture visualization instrument can be worn on the affected limb of the newborn, the tension on the strap 3 is removed. If the surgical degree of the vascular puncture visualization instrument is too large, the rebound force of the newborn's affected limb will gradually expand the space between the compression device 2 and the strap 3, thereby avoiding excessive pressure on the newborn's affected limb by the compression device 2 and the strap 3.

[0053] After completing the wearing of the vascular puncture visualization instrument, remove the dust cover 12 and then rotate the transparent bolt 11 to control the widened boss 112 to press on the puncture point to stop bleeding. The puncture point can be intuitively observed through the observation port 1110, and the condition of the puncture point can be confirmed in real time to avoid adverse situations.

[0054] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
