Hypodermic koobyog tsis txhais hais tias ib-loj-haum-tag nrho cov khoom siv. Hauv kev xyaum kho mob, lawv qhov ntev, ntsuas (G-tus nqi), kev teeb tsa cov lus qhia thiab txawm tias txoj kev sib txuas tau zoo sib txawv thiab ua kom zoo rau cov xwm txheej tshwj xeeb. Los ntawm kev txhaj tshuaj tiv thaiv kev noj qab haus huv loj rau pej xeem mus rau kev tswj hwm tus kheej tus kab mob, los ntawm kev sim tshuaj intradermal superficial mus rau kev txhaj tshuaj intramuscular sib sib zog nqus, kev xav tau kev kho mob sib txawv tau ua rau muaj tsev neeg tshwj xeeb ntawm koob. Kev nkag siab txog qhov kev hloov pauv no yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig kho tau zoo thiab txhim kho tus neeg mob kev nyab xeeb thiab kev nplij siab.

1. Kev txhaj tshuaj: Ib qho tseem ceeb ntawm kev noj qab haus huv rau pej xeem ntawm kev ua tau zoo thiab kev nyab xeeb

Kev txhaj tshuaj tiv thaiv yog qhov loj tshaj plaws ntawm daim ntawv thov ntawm cov txheej txheem txhaj tshuaj subcutaneous thiab intramuscular, nrog rau cov kev cai tseem ceeb ntawm kev nyab xeeb, kev ua haujlwm siab thiab kev tsim qauv.

Kev ntsuas thiab qhov ntev xaiv: Kev txhaj tshuaj intramuscular (xws li, COVID-19 thiab tshuaj tiv thaiv kab mob khaub thuas) feem ntau siv 22G-25G koob nrog qhov ntev ntawm 1-1.5 ntiv tes kom ntseeg tau tias cov tshuaj tiv thaiv tau xa mus tob rau hauv cov leeg deltoid lossis vastus lateralis. Cov koob luv luv (5/8 nti) tau txais yuav rau kev txhaj tshuaj subcutaneous (xws li, tshuaj tiv thaiv kab mob qhua pias) txhawm rau tsom rau cov txheej txheem rog subcutaneous.

Kev tsom xam: Kev nyab xeeb koob txhaj tshuaj yog qhov tseem ceeb hauv daim teb no. Txawm hais tias BD's auto-retractable design los yog sheath-shielded qauv los ntawm lwm tus neeg tsim khoom, lawv lub hom phiaj tseem ceeb yog tshem tawm cov kev raug mob ntawm rab koob, tiv thaiv cov neeg ua haujlwm kho mob thiab tiv thaiv kev sib kis ntawm cov kab mob hauv cov ntshav. Kev yuav khoom ntau los ntawm cov koom haum thoob ntiaj teb xws li Gavi, Lub Koom Haum Tshuaj Tiv Thaiv, tau txhawb nqa qhov kev nyiam ntawm kev txhaj tshuaj zoo.

2. Kev Tswj Mob Ntshav Qab Zib: Micro-Engineering rau Kev Nyuaj Siab Txhua Hnub

Rau cov neeg mob ntshav qab zib uas xav tau ntau yam tshuaj insulin txhua hnub, koob txhaj tshuaj yog qhov tseem ceeb uas txiav txim siab txog kev kho mob.

Ultra-fine gauge thiab ultra-thin-wall technology: Insulin cwj mem koob tau nkag mus rau kev sib tw nano-precision, nrog 33G (0.21 hli txheej txoj kab uas hla) thiab txawm tias 34G (0.18 hli txheej txoj kab uas hla) ua qauv rau cov khoom hwm. Terumo's Nano series thiab BD's Ultra-Fine series yog cov qauv kev lag luam. Los ntawm kev siv cov ntsuas zoo dua thiab cov phab ntsa nyias nyias, lawv tuav cov kab hauv lumen kom txaus rau cov tshuaj insulin txaus thaum txo qis kev raug mob thiab mob.

Precision-tswj ntev: Cov koob luv luv li 4 hli thiab 5 hli yog tsim tshwj xeeb rau kev txhaj tshuaj subcutaneous, kom ntseeg tau tias cov tshuaj insulin raug xa mus rau subcutaneous rog txheej rau cov neeg mob ntawm txhua hom lub cev (xws li cov menyuam yaus thiab cov neeg ntshiv) thiab zam kev nqus sai thiab cov ntshav-qabzib hloov pauv los ntawm kev xa tawm intramuscular.

3. Kev Txhaum Ntshav: Ib Qhov Kev Pib Ua Tau Zoo rau Kev Ntsuas

Cov koob sau ntshav muaj qhov sib txawv ntawm cov qauv tsim los ntawm cov koob txhaj tshuaj, ua qhov tseem ceeb kom tau txais cov txiaj ntsig zoo ntawm cov ntshav nrog tsawg heev hemolysis.

Npauj npaim koob: Haum rau cov menyuam yaus, cov neeg laus lossis cov neeg mob uas muaj vascular tsis zoo. Nruab nrog cov hlua txuas ntxiv tau yooj yim thiab tis-puab flanges ntawm ob sab ntawm lub hub kom yooj yim kho, lawv tso cai rau kev kho kom zoo ntawm cov kaum sab xis nrog kev puas tsuaj tsawg kawg ntawm cov hlab ntsha.

Nqus cov koob sau ntshav: Ua ke nrog lub tshuab nqus tsev nqus cov hlab ntshav, cov no yog cov khoom siv hauv cov chaw kuaj mob. Featuring ib tug ntse roj hmab pncturing spike nyob rau hauv lub rear kawg, lawv tho lub tshuab nqus tsev raj tom qab venipuncture. Cov ntshav tau txiav txim siab los ntawm qhov tsis zoo siab hauv lub raj, ua kom cov ntshav kaw tag nrho thiab tiv thaiv cov neeg ua haujlwm saib xyuas kev noj qab haus huv kev nyab xeeb thiab cov qauv kev ncaj ncees. BD's Vacutainer system yog tus qauv kub hauv ntu no.

4. Kev xa tshuaj siab kawg thiab cov xwm txheej tshwj xeeb

Kev txhaj tshuaj biologic: Ntau cov tshuaj monoclonal-antibody yog tus nqi siab, muaj kuab heev thiab xav tau kev tswj hwm subcutaneous. Pre-filled syringes tsim los rau kev siv xws li siv qhov chaw sib txuas ntawm rab koob (sawv cev los ntawm Nipro), zam kev sib cuam tshuam ntawm cov tshuaj nplaum thiab ua kom ruaj khov thiab nyab xeeb. Cov koob feem ntau yog nruab nrog cov khoom siv rov qab thim rov qab kev nyab xeeb rau kev tswj hwm tus kheej hauv tsev yooj yim.

Intradermal txhaj tshuaj thiab kev ua xua: Cov koob luv luv heev (feem ntau< 3 mm) with short bevels are used to penetrate the dermis at a shallow angle to form characteristic wheals. These are applied for tuberculin tests, local anaesthesia and certain allergen assessments.

High-pressure contrast-medium txhaj tshuaj: Contrast-enhanced CT scans yuav tsum tau hnyav-lub luag hauj lwm mob siab rau indwelling koob nrog loj gauges (piv txwv li, 18G-20G) tiv taus instantaneous siab flow rates los ntawm high-pressure injectors, kom ntseeg tau sai thiab uniformly xa ntawm qhov sib piv nruab nrab rau hauv cov ntshav.

Cov ntawv thov kho mob tau hloov mus rau qhov tseeb dua, kev sib koom ua ke thiab kev txawj ntse. Piv txwv li, auto-injectors koom ua ke cov tshuaj nrog cov koob zais, cia li ua tiav kev txhaj tshuaj thiab koob thim rov qab thaum lub pob nyem thiab ua kom yooj yim rau kev tswj hwm tus kheej ntawm biologics. Kev nyab xeeb ntawm cov ntshav sau cov cuab yeej suav nrog kev thim rov qab lossis cov txheej txheem blunting los tiv thaiv rab koob cov lus qhia tam sim tom qab kuaj. Hauv qab txhua rab koob tshwj xeeb yog qhov kev nkag siab tob rau hauv cov ntsiab lus mob tshwj xeeb - suav nrog kev pheej hmoo kis mob, mob tus neeg mob, kev ua haujlwm yooj yim thiab siv tshuaj sib raug zoo - nrog rau cov kev daws teeb meem. Xws li kev hloov kho txuas ntxiv mus thiab micro-innovation ua rau cov koob me me no tsis tuaj yeem cuam tshuam qhov tseeb cuam tshuam los ntawm kev txhawb nqa lub network loj ntawm kev kho mob niaj hnub no.
