Description

PICC puncture package is with broken skin sword

Technical Field

The utility model belongs to the technical field of medical appliances, concretely relates to PICC puncture package is with broken dermatotome.

Background

The skin tissue section shows that blood vessels distributed in a papillary layer of dermis are vertically opposite to epidermis, the thickness of the epidermis is 0.07-2 mm, and the thickness of the dermis can reach 1-2 mm, and researches show that the dermis of the epidermis of the human forearm skin is 1284.09 +/-209.96 mu m (namely 1074.12-1494.05 mu m and 1.1-1.5 mm), so that the skin cutting range is as deep as 2mm, the dermis layer or subcutaneous tissue is broken through, and the dermis and the subcutaneous tissue contain abundant vascular networks. The existing dermatotome has only one specification, the skin breaking depth is manually judged by a nurse according to experience, the reliability is low, and the dermatotome is more difficult to master for a beginner, so that the patient is easy to have much bleeding and strong pain.

SUMMERY OF THE UTILITY MODEL

To the not enough of existence among the above-mentioned prior art, the utility model provides a PICC puncture package that can effectively guide nurse to break skin degree of depth and length is with broken dermatotome.

The utility model discloses the technical scheme who adopts does:

the utility model provides a PICC puncture package is with brokenly dermatotome, includes handle of a knife, blade I or blade II, and the knife tip angle of blade I is different with the knife tip angle of blade II, and all is equipped with striking mark line on the blade of blade I and the blade of blade II. The blade I is a blade with the skin breaking length of 4.5Fr and 5Fr, and the angle of the tool nose of the blade I is 63 degrees; the blade II is a blade with the skin breaking length of 3.5Fr, and the knife point angle of the blade II is 72 degrees.

Striking mark line upwards extends to 2mm department for following the lowest of blade point and sets up the scale mark, and the scale mark can indicate the operator that breaks the skin degree of depth directly perceived, prevents that the degree of depth of breaking the skin exceeds 2mm and causes bleeding much.

The striking mark line is a striking warning line arranged at the position of 2mm of the blade point, and the striking warning line also plays a role in guiding the operator to break the skin to the maximum degree, so that the skin is prevented from being broken too deeply.

All be provided with striking supplementary spacing at the 2mm department of the blade point of blade I and the 2mm department of the blade point of blade II, striking supplementary spacing further plays the guard action, avoids broken skin degree of depth to exceed 2 mm.

And this skin breaking sword is applied to PICC puncture package, can instruct the accurate broken skin of nurse.

The utility model discloses a set up striking mark line on the blade, guide and warn the operator and break the skin degree of depth, can reduce to bleed to the patient, alleviate pain, reduce the pipe and maintain the frequency to alleviate the nervous mood of patient, reduce the cost of being in hospital. The length and the depth of the broken skin can be better mastered for nurses, secondary skin breaking or skin breaking openings are avoided being too large, tension is felt when the tube is placed, and the device especially plays a reference role for beginners.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

Example 1: a PICC puncture package is with brokenly skin sword, as shown in fig. 1-2, includes handle of a knife 1, blade I2 is for brokenly the blade of skin length 4.5Fr and 5Fr and blade I2's knife tip angle is 63.

And be equipped with striking mark line 5 on the blade point 8 of blade I2, striking mark line can be from the lowest of blade point upwards extend to 2mm department and set up the scale mark, and the scale mark can the visual indication operator brokenly the skin degree of depth, prevents that the brokenly skin degree of depth from surpassing 2mm and causing the hemorrhage to be many.

In this embodiment, the marking line can also be a striking warning line arranged at 2mm of the blade edge, and the warning line also plays a role in guiding the operator to break the skin to a maximum depth, so as to avoid overlong or overlong incision.

In order to better avoid the incision overlength or too short, a striking auxiliary limiting strip 4 is arranged at the 2mm position of the blade edge of the blade I2, the striking auxiliary limiting strip further plays a role in protection, and the phenomenon that the broken skin length is inconsistent with the used sheath due to the fact that the broken skin depth exceeds 2mm is avoided.

The skin-breaking knife of this embodiment is applied to the PICC puncture package.

Example 2: a PICC puncture package is with sword that punctures skin, as shown in fig. 3-4, includes handle of a knife 1, blade II 3 is the blade that the length of the broken skin is 3.5Fr and blade II 3's knife tip angle is 72, and is different with the knife tip angle of blade I2.

And be equipped with striking mark line 5 on the blade point 8 of blade II 3, striking mark line can be from the lowest of blade point upwards extend to 2mm department and set up the scale mark, and the scale mark can the visual indication operator brokenly the skin degree of depth, prevents that the brokenly skin degree of depth from surpassing 2mm and causing the hemorrhage to be many.

In this embodiment, the striking mark line can also be a striking warning line arranged at 2mm of the blade edge, and the warning line also plays a role in guiding the operator to break the skin to a maximum depth, so as to avoid overlong or overlong incision.

In order to better avoid the incision overlength or too short, a striking auxiliary limiting strip 4 is arranged at the 2mm position of the blade edge of the blade II 3, the striking auxiliary limiting strip further plays a role in protection, the phenomenon that the skin breaking depth exceeds 2mm to cause the skin breaking length to be inconsistent with the used sheath is avoided, and the skin breaking knife in the embodiment is applied to the PICC puncture bag.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
