Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to a pen-shaped umbilical vein puncture needle. Background Technique

[0002] During the rescue of critically ill neonates, doctors and nurses are in an extremely tense state. There are various objective difficulties in peripheral vein puncture, and the puncture success rate is not high. As a nutritional channel connecting the fetus and the mother, the umbilical vein has a thick blood vessel diameter and a thick wall, is easy to identify, greatly reduces the difficulty of catheterization, and has a very high success rate, which can shorten the time for opening a vein during emergency rescue and greatly relieve the pressure of the operating nurse. Therefore, umbilical vein puncture for injecting drugs is a commonly used operation technique for neonatal resuscitation in the delivery room. The traditional umbilical vein puncture method is to use a 7# ordinary metal needle for puncture. However, it is easy to slip off, and there are problems such as not being easy to fix, not being able to be retained, easy to pierce the blood vessel, and drug extravasation, resulting in delaying the rescue opportunity.

[0003] Umbilical vein catheterization is the fastest and most effective way to establish a venous access for neonates. The umbilical vein catheter is currently the most widely used. After the existing neonatal umbilical vein catheterization, suture fixation is generally performed with a needle and thread. However, the traditional suture process with a needle and thread is relatively cumbersome. After the neonatal umbilical cord atrophies, the sutured surgical thread will become loose, resulting in displacement and even bleeding of the catheter in the umbilical cord, affecting the treatment of neonates. Secondly, umbilical vein catheterization needs to be carried out under strict disinfection conditions. During the rescue of critically ill neonates, the operation is hasty, the disinfection is not strict enough, and it requires qualified personnel to operate. Moreover, the cost of umbilical vein catheters is relatively high, and the neonatal resuscitation equipment in the delivery rooms of different-level hospitals is not fully equipped.

[0004] Some hospitals also use indwelling needles for umbilical vein intubation, which can meet the clinical rescue drug requirements. This is an effective alternative method for rescuing critically ill neonates in units without umbilical vein catheters. However, when the current ordinary clinical indwelling needles are used for umbilical vein puncture, since the catheter is cylindrical and has a small contact area with the skin, it is easy to slide and is not easy to be fixed. Moreover, due to the wet umbilical cord, it is easy to slip off. In addition, the umbilical cord stump will atrophy over time, the blood vessels of the atrophied umbilical cord will shrivel, and the umbilical vein is not easy to identify, increasing the puncture difficulty.

[0005] Therefore, there is an urgent need to provide a needle for umbilical vein puncture to solve the problems of difficult fixation and difficult umbilical cord ligation. Content of the Utility Model

[0006] In view of the above problems, the utility model provides a pen-shaped umbilical vein puncture needle, which effectively solves the problems of difficult fixation of the puncture needle and difficult umbilical cord ligation, and is convenient for nurses to operate.

[0007] The utility model is realized through the following technical solutions:

[0008] A pen-type umbilical vein puncture needle, characterized by comprising:

[0009] The puncture needle body is an integrated structure, which is divided into a catheter seat and a puncture catheter from top to bottom. The middle of the catheter seat is recessed inward to form a limiting groove, and the diameter of the lower half of the catheter seat gradually decreases and is connected to the puncture catheter;

[0010] A pen clip device, the pen clip device is elastic and fixed to the upper part of the catheter seat;

[0011] A heparin cap, which is mounted on the top of the catheter seat;

[0012] an umbilical cord holder, the umbilical cord holder being detachably mounted on the pen clip device;

[0013] An umbilical cord fixing rope, which surrounds the puncture needle body, has one end fixed on the umbilical cord fixer, and the other end is a free end;

[0014] When the pen-type umbilical vein puncture needle is used, the umbilical cord fixator is pressed and the free end of the umbilical cord fixing rope is stretched so that the pen clip device is moved closer to the puncture needle body to fix the umbilical cord and the puncture needle; after use, the umbilical cord fixator is pressed, the puncture needle body is pulled out, the umbilical cord fixing clip is separated from the pen clip device, and the free end of the umbilical cord fixing rope is continued to be stretched to tie the umbilical cord.

[0015] Preferably, the umbilical cord fixing rope is an elastic cotton rope or cloth belt; the elastic cotton rope or cloth belt has a width of 0.3-0.5 cm and a length of 3-5 cm.

[0016] Preferably, the puncture needle body is made of polyurethane.

[0017] Preferably, when the free end of the umbilical cord fixing rope is stretched, the umbilical cord fixing rope is tightened at the horizontal position of the limiting groove.

[0018] Preferably, the heparin cap is for administration.

[0019] Preferably, the tail of the puncture catheter is pointed for puncture.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] (1) The pen-type umbilical vein puncture needle has its own umbilical cord fixation device, which can quickly fix the puncture needle compared to the common clinical indwelling needle and avoid secondary umbilical cord ligation. The puncture needle can be fixed and the umbilical cord can be ligated in one step.

[0022] (2) Pen-type umbilical vein puncture needles are relatively cheaper than umbilical vein catheters. Hospitals at all levels are capable of equipping them and can improve the equipment of neonatal rescue supplies in primary hospitals.

[0023] (3) The pen-shaped umbilical vein puncture needle can not only be used for rescuing critically ill neonates, but also for children who need infusion treatment and are immediately transferred to the neonatal department after delivery, such as premature infants, for whom it is difficult to puncture with a peripheral intravenous indwelling needle; children with neonatal hypoglycemia due to maternal gestational diabetes can save puncture time and relieve the pressure on nurses.

[0024] (4) The pen-shaped umbilical vein puncture needle does not have a self-contained needle core, which can avoid problems such as blood vessel puncture and injury caused by the traditional steel umbilical vein puncture needle. Description of the Drawings

[0027] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as "fixed to", "disposed on", "connected to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of the pen-shaped umbilical vein puncture needle of the present utility model, including a puncture needle body 1, a pen clip device 2, a heparin cap 3, an umbilical cord fixator 4 and an umbilical cord fixing cord 5; the puncture needle body 1 includes a limit groove 11, a catheter seat 12 and a puncture catheter 13; the umbilical cord fixing cord 5 is provided with a free end 51.

[0031] The puncture needle body 1 is an integrated structure, which is divided into a catheter seat 12 and a puncture catheter 13 from top to bottom. The middle of the catheter seat 12 is recessed inward to form a limiting groove 11, and the diameter of the lower half of the catheter seat 12 gradually decreases and is connected to the puncture catheter 13; the pen clip device 2 is elastic and fixed to the upper half of the catheter seat 12; the heparin cap 3 is installed on the top of the catheter seat 12; the umbilical cord fixator 4 is detachably installed on the pen clip device 2; the umbilical cord fixing rope 5 surrounds the puncture needle body, one end of which is fixed to the umbilical cord fixator 4, and the other end is a free end 51.

[0032] The utility model is mainly used for quickly opening venous access when rescuing a newborn after birth or when intravenous medication is needed for hypoglycemia at birth. At 2 cm away from the root of the umbilical cord, the pen-type umbilical vein puncture needle of the utility model is used to directly puncture the umbilical vein section. After puncturing, blood is returned. After 0.5-1 cm is advanced, the umbilical cord fixer 4 with the utility model is directly used to lock it. Specifically, the umbilical cord fixer 4 is pressed and the free end 51 of the umbilical cord fixing line 5 is stretched at the same time, so that the pen clip device 2 is moved closer to the puncture needle body 1 to clamp the umbilical cord and fix the puncture needle; then the medicine is pushed at the heparin cap 3. After the rescue is completed and other effective venous accesses have been established, the umbilical cord fixer 4 is pressed, the needle body is directly pulled out, and the free end 51 of the umbilical cord fixing line 5 is further stretched to lock the umbilical cord until the umbilical cord naturally dries and falls off, eliminating the need for secondary processing of the umbilical cord.

[0033] The puncture needle catheter seat 12 is designed with a limiting groove 11. When the free end 51 of the umbilical cord fixing rope 5 is stretched, the umbilical cord fixing rope 5 is tightened at the horizontal position of the limiting groove 11, which is more conducive to fixing the umbilical cord with the rope and preventing the puncture needle from slipping due to the umbilical cord being moistened.

[0034] The pen clip device 2 is fixed to the upper part of the catheter seat 12. On the one hand, it facilitates the holding of the puncture needle, puncture and withdrawal of the needle body; on the other hand, the pen clip device is elastic and can clamp the umbilical cord together with the puncture needle body when the umbilical cord fixator and the umbilical cord fixing rope are tightened, thereby preventing the umbilical cord from slipping and facilitating drug administration.

[0035] In one example, the umbilical cord fixing strip is an elastic cotton rope or a wide cloth strip with a width of about 0.3-0.5cm and a length of about 3-5cm. It is convenient for locking the umbilical cord without breaking it easily. The inherent elasticity is more conducive to tightening the seal, and the puncture needle can be fixed while locking the umbilical cord, eliminating the trouble of secondary ligation of the umbilical cord.

[0036] In one example, the puncture needle body is made of polyurethane, and the puncture catheter is a BD Wanlong catheter, which is soft and hard enough to perform puncture independently without relying on a steel needle.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0038] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
