Description

Vascular positioning auxiliary device

Technical Field

The utility model relates to the field of medical auxiliary instruments, in particular to a blood vessel positioning auxiliary device.

Background

Newborns in neonatal care units often need to draw blood for biochemical, routine, blood culture, blood gas analysis, etc. examinations. However, the blood vessels of the newborns are thin, and the blood vessels are difficult to actively fit when blood is taken, so that the situations of unobvious pulsation, anatomical position variation and the like are often caused due to poor circulation, and finally, the blood taking failure is caused, so that the failure rate of blood taking of the newborns is increased, and repeated puncture blood taking is required.

The structure of the handheld near infrared venous blood vessel display is mainly disclosed in a patent number CN104027072A and a patent name of scanning type venous blood vessel synchronous imaging and indicating device and method, the handheld near infrared venous blood vessel display comprises a near infrared LED light source for illuminating blood vessels and an imaging lens, a scanning galvanometer is arranged between the imaging lens and an imaging plane of the imaging lens, a linear array photoelectric sensing element capable of sensing near infrared light is arranged on the imaging plane after the scanning galvanometer reflects, a near infrared interference filter is arranged between the imaging plane where the linear array photoelectric sensing element is arranged and a reflected light optical axis of the scanning galvanometer, the near infrared interference filter is parallel to a mirror surface of the scanning galvanometer when the scanning type venous blood vessel synchronous imaging and indicating device and method is static, a visible light LED array is connected to a driving end of a signal processing and driving circuit, and a projection lens is further arranged between the visible light LED array and the near infrared interference filter. The linear array photoelectric sensing element is mainly used for receiving scanning imaging signals, the blood vessel is indicated by the visible light LED array in a discrete light spot mode after analog or digital processing of photoelectric signals, and the position of the vein blood vessel can be displayed on the surface of the skin, so that medical staff can more accurately find the position of the vein blood vessel.

Taking an arm as an example, when the near infrared light venous blood vessel display instrument is used, one hand of medical staff needs to hold the near infrared light venous blood vessel display instrument, the other hand needs to position the arm of the neonate, and the arm of the neonate is prevented from shaking, so that the medical staff cannot perform operations such as intravenous injection while using the near infrared light venous blood vessel display instrument, and therefore, the other hand needs to hold the near infrared light venous blood vessel display instrument, and the injection can be completed under the condition that the venous blood vessel position is displayed through the near infrared light venous blood vessel display instrument.

However, the number of medical staff in the neonatal care unit is limited, each medical staff needs to be responsible for a plurality of newborns, and most of newborns perform operations such as injection, blood sampling inspection and the like in the same time, so that it is difficult to realize that two medical staff simultaneously perform injection and blood sampling on one newborns in the time period. The neonatal guardian is not allowed to enter the neonatal guardian, and the near infrared venous vascular display device and the limb for fixing the neonate cannot be assisted, so that the near infrared venous vascular display device capable of marking blood vessels is needed.

Disclosure of Invention

The present utility model is intended to provide a blood vessel positioning auxiliary device to be able to mark a blood vessel without using a near infrared light vein blood vessel display.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the vascular positioning auxiliary device comprises a shell and a vascular indicator lamp, wherein the vascular indicator lamp is arranged at one end of the shell, a marking unit is arranged on the shell, the marking unit comprises a rotating shaft and a marking pen, and the rotating shaft penetrates through the shell and is in running fit with the shell; the marker pen is connected with the rotating shaft, and the distance between one end of the marker pen far away from the rotating shaft and the rotating shaft is greater than the axial distance between the blood vessel indicator lamp and the rotating shaft.

The near infrared light vein blood vessel display is more convenient to carry about and use.

Further, a positioning rod is arranged on the first rotating part, penetrates through the first rotating part and can move along the axial direction of the positioning rod relative to the first rotating part.

The beneficial effect of this scheme is: after the through hole is cut out on the bag mouth cloth in advance, when the shell and the first rotating part are clamped on the bag mouth cloth, the positioning rod can be screwed in to pass through the through hole, so that the connection strength with the bag mouth cloth is improved, and the near infrared light venous blood vessel display instrument is further prevented from falling.

Further, the positioning rod is in threaded connection with the first rotating portion.

The beneficial effect of this scheme is: the locating lever in this scheme is connected with first rotation portion, can avoid the locating lever to drop from first rotation portion, further improves fixed effect.

Further, a groove opposite to the positioning rod is formed in the shell, and the end part of the positioning rod is located in the groove.

The beneficial effect of this scheme is: the recess can be close to the one end of shell to the locating lever and carry out spacingly, can follow the both sides of locating lever with first rotation portion cooperation and fix a position, improves the location effect to the locating lever.

Further, the part of the rotating shaft, which is positioned outside the shell, is a prism, the first rotating part is provided with a through groove opposite to the rotating shaft, and one end of the rotating shaft, which is far away from the shell, is detachably connected with the through groove.

The beneficial effect of this scheme is: the relative rotation between the rotating shaft and the first rotating part can be avoided, and the first rotating part is driven to rotate more conveniently through the rotating shaft. In the in-service use, because first rotation part and second rotation part stretch out, when receiving pressure or shell drop and appear the collision between with ground or desktop, first rotation part and second rotation part have the risk of deformation or damage, in this scheme, because first rotation part can be torn down from the pivot, so can tear down after first rotation part or second rotation part warp, change new first rotation part and second rotation part.

Further, an elastic sleeve is fixed in the clamping groove.

The beneficial effect of this scheme is: after the marking part is clamped into the clamping groove, the elastic sleeve is elastically deformed, so that the pressure on the marking part can be increased, and the fixing effect on the marking part is improved.
