Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of venous detaining needle with precision liquid medicine filter.
Background technology
Often need the venoclysis medicinal liquid in the clinical transfusion process; Some medicinal liquid such as ampicillin, ceftriaxone sodium etc.; Contain a large amount of rubber particles, fibre glass and insoluble drug particle in the medicinal liquid, existing venous detaining needle lacks secondary filter, direct socket syringe in the time of need quietly pushing away medicine; A large amount of rubber particles, fibre glass and insoluble drug particle just get into human vas with medicinal liquid, bring harm to patient.
The utility model content
The purpose of this utility model is the deficiency of the above-mentioned existence of customer service, and a kind of venous detaining needle of band precision liquid medicine filter of simple in structure, easy to operate, good filtration effect is provided.
The technical scheme that this utility model is adopted to achieve these goals is following:
A kind of venous detaining needle with precision liquid medicine filter; It comprises needle stand, long duct, flow-stopping clip, catheter block and calparine cap; It is characterized in that also comprising a precision liquid medicine filter; Said needle stand and catheter block are connected to the long duct two ends, also are provided with a flow-stopping clip on the long duct, and said precision liquid medicine filter is connected on the long duct between flow-stopping clip and the catheter block.
A kind of venous detaining needle with precision liquid medicine filter described in this utility model is characterized in that also being provided with on the said catheter block calparine cap and block.
A kind of venous detaining needle with precision liquid medicine filter described in this utility model is characterized in that said needle stand is connected to form by casing seat, batching pig, sleeve pipe rivet, sleeve pipe, needle tubing from the bottom up; Said needle tubing needle point is exposed at outside the sleeve pipe, and other parts of needle tubing are enclosed within the sleeve pipe.Said needle tubing and sleeve pipe all cover in the protective sleeve.
This utility model is through being provided with a precision liquid medicine filter on long duct; Thereby prevented that effectively a large amount of rubber particles, fibre glass and insoluble drug particle etc. from getting into human vas with medicinal liquid; Guarantee the healthy and safe of patient, therefore the utlity model has advantages such as simple in structure, easy to operate, that safety is good.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is the needle stand structural representation.
Among the figure: the 1-needle stand; The 2-casing seat; The 3-batching pig; 4-sleeve pipe rivet; The 5-sleeve pipe; The 6-needle tubing; The 7-protective sleeve; The 8-long duct; The 9-flow-stopping clip; The 10-precision liquid medicine filter; The 11-catheter block; The 12-calparine cap; The 13-block.
The specific embodiment
To combine accompanying drawing that the technical scheme of this utility model is further specified below.
Like Fig. 1, shown in 2: a kind of venous detaining needle with precision liquid medicine filter, it comprises needle stand 1, long duct 8, flow-stopping clip 9, catheter block 11 and calparine cap 12.Wherein said needle stand 1 is connected to form by casing seat 2, batching pig 3, sleeve pipe rivet 4, sleeve pipe 5, needle tubing 6 from the bottom up.Needle tubing 6 needle points are exposed at outside the sleeve pipe 5, and other parts of needle tubing 6 are enclosed within the sleeve pipe 5, and needle tubing 6 all covers in the protective sleeve 7 with sleeve pipe 5.Said needle stand 1 is connected to long duct 8 two ends with catheter block 11, also is provided with a flow-stopping clip 9 on the long duct 8.Wherein also be provided with calparine cap 12 and block 13 on the catheter block 11.The improvements of this utility model are on the long duct 8 between flow-stopping clip 9 and the catheter block 11, to set up a precision liquid medicine filter 10.
This utility model is being through being equipped with a precision liquid medicine filter on long duct, when giving that patient is quiet to push away the infusion medicinal liquid, can better rubber particle, fibre glass and insoluble drug particle be filled into externally, reduces the harm to patient.
