Description
Technical field:
This utility model relates to a kind of ring first membrane orienting anaesthetic puncture needle, belongs to medical apparatus and instruments.
Background technology:
Thyrocricoid puncture method is in a large number for the anesthesia of fiberoptic bronchoscopy and treatment.Current ring first film is threaded a needle and in use be there is following defect: sharp keen needle point is always at tracheal strips in administration, and to after the stimulation of trachea during administration, the stress of patient can cause accidentally injuring; Syringe needle directly faces toward tunica mucosa tracheae at tracheal strips, if administration is very fast, pressure has unnecessary damage compared with great Yi to mucosa; Medicine-feeding part is inaccurate, this site of anesthesia mainly more than ring first film, below glottis: needle section porose person herbal sprinkling, at flat ring first film and with lower portion, does not reach ideal effect; Porose and the person that has side opening of needle section: main flow is also in needle section, and side opening upwards pressure deficiency, still can not arrive effective site of anesthesia; In order to reach anaesthetic effect, meeting administration is very fast, intensified pressure, virtually add dosage, but effective dose is less, and dosage is inaccurate.
Utility model content:
The purpose of this utility model is to provide a kind of directed anesthesia, accurate positioning; Evade accidental injury when administration stimulates; Less to mucosa injury; Little but a kind of ring first membrane orienting anaesthetic puncture needle that effective dose is relatively large of dosage.
This utility model is implemented by following technical scheme: a kind of ring first membrane orienting anaesthetic puncture needle, and it comprises stylophore and the nook closing member inserted in described stylophore that slides, and is provided with stylophore seat, is provided with sealing sponge in described stylophore seat at the end of described stylophore; Slide through the described sealing sponge in described stylophore seat and insert in described stylophore in described nook closing member top, described nook closing member top passes from described stylophore top, is provided with the nook closing member deck of rotary clamping in described stylophore seat at described nook closing member end; Be provided with in described nook closing member into medicine blind hole, described in enter the opening of medicine blind hole as on described nook closing member deck; The outer wall of described stylophore top and bottom is respectively equipped with one and above medicine outlet, the described medicine outlet quantity of described stylophore top exterior walls is more than the described medicine outlet quantity of described stylophore bottom outer wall, and the described medicine outlet bore of described stylophore top exterior walls is greater than the described medicine outlet bore of described stylophore bottom outer wall; On described nook closing member outer wall in described stylophore corresponding be provided be communicated with described medicine outlet and described enter the drug delivery port of medicine blind hole.
Preferred, described stylophore seat is provided with the medicine outlet labelling corresponding with the described medicine outlet of stylophore top exterior walls protruding.
Advantage of the present utility model: directed anesthesia, accurate positioning; Evade accidental injury when administration stimulates; Less to mucosa injury; Dosage is little but effective dose is relatively large; Structure is simple, easy to use, is easy to produce.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of stylophore.
Fig. 3 is the structural representation of nook closing member.
Stylophore 1, nook closing member 2, stylophore seat 3, sealing sponge 4, nook closing member deck 5, enter medicine blind hole 6, medicine outlet 7, medicine outlet labelling projection 8, drug delivery port 9.
Detailed description of the invention:
As shown in Figure 1 to Figure 3, a kind of ring first membrane orienting anaesthetic puncture needle, it comprises stylophore 1 and the nook closing member 2 inserted in stylophore 1 that slides, and is provided with stylophore seat 3, is provided with sealing sponge 4 in stylophore seat 3 at the end of stylophore 1; Slide through the sealing sponge 4 in stylophore seat 3 and insert in stylophore 1 in nook closing member 2 top, nook closing member 2 top passes from stylophore 1 top, is provided with the nook closing member deck 5 of rotary clamping in stylophore seat 3 at nook closing member 2 end; Be provided with into medicine blind hole 6 in nook closing member 2, enter the opening of medicine blind hole 6 as on nook closing member deck 5; The outer wall at stylophore 1 top is provided with two medicine outlets 7, the outer wall bottom stylophore 1 is provided with a medicine outlet 7, medicine outlet 7 bore of stylophore 1 top exterior walls is greater than medicine outlet 7 bore of stylophore 1 bottom outer wall; Stylophore seat 3 is provided with the medicine outlet labelling projection 8 corresponding with the medicine outlet 7 of stylophore top exterior walls; On nook closing member 2 outer wall in stylophore 1, corresponding being provided with is communicated with medicine outlet 7 and the drug delivery port 9 entering medicine blind hole 6.
Using method: use the nook closing member 2 couples of patients be enclosed within stylophore 1 to carry out thyrocricoid puncture, after completing puncture, rotate nook closing member deck 5, the pointed tip of nook closing member 2 is returned in stylophore 1, prevent from, in administration because the emergency reaction of patient causes accidental injury, the top of stylophore 1 being blocked simultaneously; Drug delivery port 9 after rotating on nook closing member 2 outer wall will enter medicine blind hole 6 and be communicated with medicine outlet 7, anaesthetic is injected from entering medicine blind hole 6, anaesthetic is from ejection in medicine outlet 7 setting up and down, the medicine outlet 7 that bore is greater than stylophore 1 top exterior walls of the medicine outlet 7 of stylophore 1 bottom outer wall sprays mouth as main anaesthetic, realizes the little but relatively large effect of effective dose of dosage; The administration direction of mouth is sprayed for the anaesthetic of pointing out medical personnel main in the medicine outlet labelling projection 8 of stylophore seat 3; Sealing sponge 4 in stylophore seat 3 prevents the gap of the anaesthetic in nook closing member 2 between nook closing member 2 and stylophore 1 from flowing out between stylophore seat 3 and nook closing member deck 5, and plays the stability of maintenance nook closing member 2 in stylophore 1, avoids accidentally injuring.
