Description
Technical field
The utility model relates to a kind of Medical Devices of pediatric patient, and in particular to a kind of children's single nerve block set
Part.
Background technique
Single (discontinuous) or continuous nerve block can directly act on targeting target and mitigate surgical pain, not only reduce
The dosage of general anesthesia drug reduces the adverse reaction being generated by it, and good analgesia can be also provided for postoperative patient, reduces
Stress reaction, more conducively postoperative quick recovery improve patient satisfaction and Clinical Outcome.But in pediatric patient, mind is carried out
Be often used often through being blocked for adult nerve block external member, although the puncture needle that model can be selected less than normal in clinical manipulation and
The connecting tube of low capacity, there are still many drawbacks, such as can not between local anaesthetics and physiological saline free switching, if by injecting office
Anaesthetic judges that needle position will lead to excessive local anaesthetics injection or muscle/intravascular injection, small size needle length are too short not
It is suitble to the operation of children's metastomium, puncture needle type is excessive to cause more puncture wounds etc..
Therefore, it is necessary to improve to the prior art.
Utility model content
The children that the technical problem to be solved by the present invention is to provide a kind of ultrasonic developments to understand, simple and practical in structure are single
Secondary nerve block external member.
In order to solve the above technical problems, the utility model provides a kind of children's single nerve block external member: including connecting tube
One, connecting tube two and puncture needle；
The puncture needle includes sequentially connected syringe needle, shank and backshank, is arranged with Y-connector on backshank；The Y type
Connector is connected to one end of connecting tube one and connecting tube two respectively, and one other end of connecting tube is infused with the local anaesthetics equipped with local anaesthetics
Emitter connection, two other end of connecting tube are connect with the physiological saline device equipped with physiological saline；
Folder, which is provided with, in the connecting tube one closes device one；Folder, which is provided with, in the connecting tube two closes device two.
As the improvement to the utility model children's single nerve block external member:
The folder closes device one and is located at connecting tube one close to local anaesthesia syringe one end；The folder closes device two and is located at connecting tube two
Close to physiological saline device one end.
As the further improvement to the utility model children's single nerve block external member: the connecting tube one and connecting tube
Two length is different.
As the further improvement to the utility model children's single nerve block external member: the length of the connecting tube one is
15cm, the length of connecting tube two are 30cm.
As the further improvement to the utility model children's single nerve block external member: the puncture needle is metal puncture
Pipe, the length of puncture needle are 3cm.
As the further improvement to the utility model children's single nerve block external member: the inclined-plane of the syringe needle is 45 °.
The technical advantage of the utility model children's single nerve block external member are as follows:
The utility model discloses a kind of nerve block external member for children, including metal puncture needle, two inner capacities
The plastic union pipe of respectively 0.3ml and 0.4ml, respective connecting puncture needle and the syringe equipped with drug.The model of puncture needle
(26G) and length (3cm) are more suitable for pediatric patient, and the puncture needle of metal quality is conducive to ultrasonoscopy, the Y of puncture needle tail end
Type connector is conducive to judge puncture needle head position by injecting physiological saline, while avoiding the physiology being detained in connecting tube
Salt water dilutes local anaesthesia concentration；In addition, the connecting tube by two kinds of different models distinguishes physiological saline and local anaesthetics, it can be more preferable
Reduction unexpected local anaesthetics injection, increase the safety of operation.Thus more convenient comfortable assistance operator passes through puncture
Needle injecting normal saline or local anaesthetics improve the efficiency of operation without replacing drug or reconnecting puncture needle and connecting tube.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model children single nerve block external member.
Specific embodiment
The utility model is described further combined with specific embodiments below, but the protection scope of the utility model is simultaneously
It is not limited only to this.
Embodiment 1, children's single nerve block external member, as shown in Figure 1, including connecting tube 1, connecting tube 2 32 and wearing
Pricker 1.
Puncture needle 1 includes syringe needle 11, shank 12 and backshank 13, and the note of connection syringe needle 11 and backshank 13 is provided in shank 12
Pipeline is penetrated, Y-connector 2 is arranged on backshank 13, the inclined-plane of syringe needle 11 is 45 °.Y-connector 2 respectively with connecting tube 1
Be connected to one end of connecting tube 2 32 (as Y-connector 2 altogether there are three interface, three interfaces respectively with puncture needle 1, even
Adapter tube 1 is connected to connecting tube 2 32), the other end and (the local anaesthesia syringe 41 of local anaesthesia syringe 41 of connecting tube 1
Capacity is 20ml, wherein being equipped with local anaesthetics) connection, the other end and 42 (physiology salt of physiological saline device of connecting tube 2 32
42 capacity of water syringe is 5ml, wherein being equipped with physiological saline) connection.
Connecting tube 1 closes device 1 being provided with folder close to 41 one end of local anaesthesia syringe, close in connecting tube 2 32
42 one end of physiological saline device is provided with folder and closes device 2 52.Folder closes device 1 and folder closes device 2 52 and can control connecting tube one respectively
31 and connecting tube 2 32 conducting close.
