Abstract
The utility model provides a honeycomb type local infiltration anesthesia needle, includes needle tubing, syringe needle, it has a liquid hole to open on the needle tubing wall, the syringe needle is the real core syringe needle of no through -hole. Go out the lower part of liquid pore size distribution at the needle tubing. Go out liquid hole regular spread, go out the distance of liquid hole between rather than the play liquid hole of periphery and equal. It is cellularly to go out the liquid pore size distribution. The problem of traditional multiple spot puncture method big to patient's cutaneous lesion, the wound is many, the infection probability is big is solved, the painful degree of patient is lower, simultaneously owing to go out liquid hole regular spread, go out the distance of liquid hole between rather than the play liquid hole of periphery and equal. The pore size distribution of play liquid is cellularly, and the narcotic disperse is soaked can be very even.
Description
Technical field
This utility model designs a kind of anesthetic needle, specifically a kind of honeycomb type local infiltration anesthesia pin.
Background technology
Local infiltration anesthesia system body surface minor operation and the ordinary anesthesia of body surface wound, Normal practice is clinically at present: carry out multiple spot puncture to operative site, fractional injection anesthetis.There is following shortcoming in this anesthesia:
One is multiple spot puncture, and large to patient skin damage, wound is many, add the probability of infection, and patient is very painful;
Two is that anesthetis disperse infiltration is uneven.
Summary of the invention
For above-mentioned technical problem, the utility model proposes a kind of honeycomb type local infiltration anesthesia pin, comprise needle tubing, syringe needle, described needle tubing wall has liquid outlet, described syringe needle is the real core syringe needle without through hole.Described liquid outlet is distributed in the bottom of needle tubing.Described liquid outlet is regularly arranged, and the distance between liquid outlet and the liquid outlet of its periphery is equal.Described liquid outlet distribution is in cellular.
Beneficial effect: owing to being provided with multiple liquid outlet on needle tubing wall, syringe needle is real core syringe needle, runs into the operation needing multiple spot to puncture clinically, can use this syringe needle, after once arriving assigned address from skin penetrating, inject anesthetis, anesthetis sprays from liquid outlet, achieves some puncture, solve traditional multiple spot puncture method large to patient skin damage, wound is many, infect the problem that probability is large, and patient's distress level is lower; Because liquid outlet is regularly arranged, the distance between liquid outlet and the liquid outlet of its periphery is equal.Described liquid outlet distribution is in cellular, and anesthetis disperse infiltrates can be very even.
figure of description
Fig. 1 is honeycomb type local infiltration anesthesia needle construction schematic diagram.
Wherein: needle tubing 1, syringe needle 2, liquid outlet 3.
detailed description of the invention:
Embodiment 1: as shown in Figure 1, a kind of honeycomb type local infiltration anesthesia pin, comprises needle tubing 1, syringe needle 2, and described needle tubing 1 wall has liquid outlet 3, and described syringe needle 2 is the real core syringe needle without through hole.Described liquid outlet 3 is distributed in the bottom of needle tubing.Described liquid outlet 3 is regularly arranged, and the distance between liquid outlet and the liquid outlet of its periphery is equal.Described liquid outlet 3 distributes in cellular.
Embodiment 2: as shown in Figure 1, a kind of honeycomb type local infiltration anesthesia pin, comprises needle tubing 1, syringe needle 2, and described needle tubing 1 wall has liquid outlet 3, and described syringe needle 2 is the real core syringe needle without through hole.Described liquid outlet 3 is distributed in the bottom of needle tubing.Described liquid outlet 3 is regularly arranged, and the distance between liquid outlet and the liquid outlet of its periphery is equal.Described liquid outlet 3 distributes in cellular.Owing to being provided with multiple liquid outlet 3 on needle tubing wall, syringe needle 2 is real core syringe needle, runs into the operation needing multiple spot to puncture clinically, can use this syringe needle, after once arriving assigned address from skin penetrating, inject anesthetis, anesthetis sprays from liquid outlet 3, achieves some puncture, solve traditional multiple spot puncture method large to patient skin damage, wound is many, infect the problem that probability is large, and patient's distress level is lower; Because liquid outlet is regularly arranged, the distance between liquid outlet and the liquid outlet of its periphery is equal.Described liquid outlet distribution is in cellular, and anesthetis disperse infiltrates can be very even.
