Abstract
The utility model provides a novel dark vein pjncture needle, including bodkin head puncture cylinder, fine needle head puncture cylinder, bodkin head, fine needle head, its characterized in that: the needle file setting that the fine needle head passes through the bodkin head is in the bodkin head, and fine needle scalp acupuncture point leaks cruelly outside bodkin scalp acupuncture point under the normal conditions, bodkin scalp acupuncture seat anterior segment is provided with retractable device. This conceptual design is ingenious, is carrying out dark vein when puncture through this scheme, and medical personnel can utilize not only that the integrative structure of bodkin and fine needle is accurate to find dark venous position, and the fine needle head still is connected with the puncture cylinder in addition, presses the puncture cylinder through taking out, according to the size of blood flow, further judges whether be dark vein, and this scheme has apparent practicality, is accepted the popularization by market very easily.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, is specifically related to a kind of Novel deep vein puncture needle.
Background technology
In medical practice, deep vein puncture technology is an important diagnostic techniques, and deep vein puncture is widely applied to major operation and rescues in critical patient.In order to avoid accidentally injuring large artery trunks, generally require before deep vein puncture at present and detect with tiny fine needle, first judge position and the direction of Deep venou, after change again bodkin carry out next step operation, but when changing bodkin, since it is desired that taking-up fine needle, penetrate bodkin again, so operation needs medical personnel rule of thumb to operate with range estimation, once operational error, bodkin cannot enter Deep venou smoothly, in addition it is also necessary to again detects, but also exist and prick aortic danger by mistake, the secondary injury of patient can be caused.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is proposed that a kind of simple in construction, bodkin and the Novel deep vein puncture needle of fine needle one.
For realizing the purpose of this utility model, the utility model proposes a kind of Novel deep vein puncture needle, including thick needle piercing needle cartridge, fine needle piercing needle cartridge, thick needle, fine needle, it is characterized in that: described fine needle is arranged in thick needle by the needle stand of thick needle, fine needle needle point leaks cruelly outside thick needle needle point under normal circumstances, and described thick needle needle stand leading portion is provided with telescopic mounting.
Thick needle needle stand leading portion telescopic mounting described further is that thick needle is outside equipped with external screw thread, thick needle needle stand is internally provided with matched female thread, after fine needle detects Deep venou, twist thick needle, make thick needle needle point just align with fine needle needle point.
Further when fine needle detects Deep venou, pumpback pressure fine needle piercing needle cartridge can be carried out, further determined whether as Deep venou by blood volume.
The beneficial effects of the utility model are: this programme design is ingenious, by this programme when carrying out deep vein puncture, medical personnel are possible not only to utilize bodkin to find the position of Deep venou accurately with fine needle structure integrally, and fine needle is the most separately externally connected with piercing needle cartridge, by taking out pressure piercing needle cartridge, according to the size of blood volume, further determine whether as Deep venou, the program has significant practicality, it is easy to be acceptable to the market popularization.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is structural representation of the present utility model.
1. fine needle piercing needle cartridge 2. thick needle piercing needle cartridge 3. fine needle 4. telescopic mounting 5. thick needle.
Detailed description of the invention
It is structural representation of the present utility model referring to Fig. 1, the utility model proposes a kind of Novel deep vein puncture needle, including thick needle piercing needle cartridge 2, fine needle piercing needle cartridge 1, thick needle 5, fine needle 3, it is characterized in that: described fine needle 3 is arranged in thick needle 5 by the needle stand of thick needle 5, fine needle 3 needle point leaks cruelly outside thick needle 5 needle point under normal circumstances, and described thick needle 5 needle stand leading portion is provided with telescopic mounting 4.
During use, first carry out Deep venou by fine needle 3 to detect, after penetrating skin, take out pressure fine needle piercing needle cartridge 1, according to the size of blood volume, further determine whether as Deep venou, after confirming as Deep venou, the telescopic mounting 4 of twisting thick needle 5 needle stand leading portion, makes thick needle 5 needle point just align with fine needle 3 needle point, then carries out next step operation.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model, and the technology contents of the most detailed description of this utility model is known technology.
