Description
Technical field
This utility model belongs to biological and medical art, is specifically related to a kind of rabbit pleura cavity puncture needle.
Background technology
Pleura cavity puncture is necessity operation of rabbit respiratory system experiment in the middle of Medical Function teaching and scientific research, and pleura cavity puncture needle is the basic device detecting rabbit intrapleural pressure under physiology and pathological model state.Traditional rabbit pleura cavity puncture needle adopts the diameter of cab-over design and pin less, after penetrating thoracic wall muscle in operation, syringe needle is very easy to be organized or blood clot blocks, therefore cannot be recorded to intrapleural pressure, the position repeatedly adjusting needle point can cause laboratory animal that thoracic cavity internal hemorrhage and pneumothorax occur thus cause the failure of testing; Because site of puncture is at rabbit thoracic wall, traditional puncture needle cannot be fixed, and this also carries out bringing very large difficulty to experiment.
Utility model content
The problem that this utility model easily blocks mainly for existing rabbit pleura cavity puncture needle syringe needle, cannot fix, provides the rabbit pleura cavity puncture needle that a kind of structure is simple, puncture wound is little, efficiency is high.
This utility model is the technical scheme taked that solves the problem:
A kind of rabbit pleura cavity puncture needle, comprise No. I silica gel tube, No. II silica gel tube, puncture needle, wherein: also comprise tee T, water manometer, ring for fixing and syringe, described puncture needle is arranged on one end of No. I silica gel tube, the other end of No. I silica gel tube is connected with tee T port, another port of tee T is connected with one end of No. II silica gel tube, the other end of No. II silica gel tube communicates with water manometer, 3rd port of tee T is provided with syringe, the needle point of described puncture needle is ramp structure, the top of puncture needle is helicitic texture, ring for fixing is arranged on puncture needle top and mates with helicitic texture, multiple side opening is offered in puncture needle lower circumference.
This utility model adopts technique scheme, the needle point of puncture needle is ramp structure and arranges side opening at puncture needle bottom different directions, the saturating thoracic wall of so easy thorn enters pleural space, after needle point enters rabbit pleural space, the inclined-plane of needle point and neighbouring side opening communicate with pleural space at once, namely detect by water decompression meter or pressure transducer and be recorded to intrapleural pressure, the damage avoiding traditional method repeatedly to regulate the position of puncture needle to cause and pneumothorax etc., puncture needle top is connected with helicitic texture, the degree of depth of piercing needle can with fixation clamp with the use of fixing puncture needle can be regulated by rotating ring for fixing, puncture needle afterbody is connected with silica gel tube, silica gel tube is connected with three-way valve, an interface of three-way valve is connected with a syringe, after pleura cavity puncture success, by the direction of the opening of regulating three-way valve with syringe is bled and gas injection, change various physiology and pathological model that rabbit is prepared in intrapleural pressure.Therefore, this utility model can be easy to puncture successfully and record intrapleural pressure, and the damage to family's rabbit chest when reducing puncture.Compared with traditional tack lancet puncture method, this utility model has the following advantages: rabbit pleura cavity puncture device, can be easy to puncture successfully and record intrapleural pressure, and the damage to family's rabbit chest when can reduce puncture.Compared with traditional tack lancet puncture method, have the following advantages: 1, pleura puncture success rate is high, because puncture needle adopts plagiocephaly and side opening design, greatly reduce syringe needle and organized the probability with blood clot blocking; 2, regulate the degree of depth of puncture needle by rotating fixed disk nut thus go for the different rabbit of body weight; 3, by fixation clamp and fixed disk, puncture needle is fixed on rabbit skin, prevents up and down or side coil moves; 4, the connected mode by tee T change thoracic puncture manufactures various pneumothorax model or detects intrapleural pressure power; 5, device is simple to operate, improves conventional efficient, reduces the risk of the failure of an experiment; 6. apparatus structure is simple, portable and cleaning and sterilizing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of rabbit pleura cavity puncture needle, comprise No. I silica gel tube 1, No. II silica gel tube 2, puncture needle 3, wherein: also comprise tee T 4, water manometer 5, ring for fixing 6 and syringe 7, described puncture needle 3 is arranged on one end of No. I silica gel tube 1, the other end of No. I silica gel tube 1 is connected with a port of tee T 4, another port of tee T 4 is connected with one end of No. II silica gel tube 2, the other end of No. II silica gel tube 2 communicates with water manometer 5, 3rd port of tee T 4 is provided with syringe 7, the needle point of described puncture needle 3 is ramp structure, the top of puncture needle 3 is helicitic texture 8, ring for fixing 6 is arranged on puncture needle 3 top and mates with helicitic texture 8, multiple side opening 9 is offered in puncture needle 3 lower circumference.
Use operating procedure of the present utility model is as follows: the first step: anaesthetize and fix rabbit, the needs experimentally required, determines required pleura cavity puncture position, and carries out the sterilization of preserved skin and site of puncture.Second step: experimentally the ring for fixing of the difference of animal large young pathbreaker rabbit pleura cavity puncture needle rotates the suitable position regulated.3rd step: connect a whole set of experimental provision, and the puncture needle position identical with tonotransducer or water manometer is adjusted in the position of three-way valve.4th step: the skin cutting site of puncture is separated subcutaneously selects the upper limb inserting needle of the lower rib of site of puncture to exposing thoracic wall muscle, is felt to have to fall through and namely be can be observed the change of pleural pressure after sense by tonotransducer or water manometer.5th step: ring for fixing is embedded in otch subcutaneous, can fix puncture needle with fixation clamp clamping skin.
In order to explain the technical solution of the utility model further, below by specific embodiment, utility model is described in detail.
Such as by one rabbit body weight 2.5Kg respiratory dysfunction experiment in pleura cavity puncture.First by family's rabbit anesthesia, be fixed on rabbit operating-table and choose site of puncture preserved skin sterilization.By being with side opening plagiocephaly puncture needle to be connected with adjusting nut in rabbit pleura cavity puncture needle, adjust the height of ring for fixing, and be connected successively with three-way valve, water manometer 7 or gas pressure transducer with silica gel tube, and three-way valve is transferred to shown in the location drawing 1 in figure.Cut the osculum that a 1cm is long in rabbit thoracic wall site of puncture, blunt separation subcutaneous tissue exposes thoracic wall muscle, and hand-held adjusting nut punctures thoracic wall muscle along rib upper limb under site of puncture.Now observe water manometer and can see that namely rabbit intrapleural pressure change punctures successfully.Wrap dish with otch surrounding skin, and clamp skin with fixation clamp and fix puncture needle, operation completes.
