Catheter muchina wekurapa weKirasi II, chubhu inopinzwa mudundira neiyo urethra kuti ibvise weti, inonyanya kushandiswa kune varwere vane weti yekuchengeta kana dundira, incontinence, varwere vanoda mubhedha kwenguva refu kana chinzvimbo chekumanikidzwa, uye varwere. mu perioperative nguva yekuvhiya maitiro.Macatheter anowanzo kupatsanurwa kuita gumi nematatu mamodheru ane zvirevo kubva pa6F kusvika 30F zvinoenderana nedenderedzwa redhayamita rekunze, uye mamodheru mana e12F, 14F, 16F uye 18F anowanzoshandiswa kuvanhu vakuru.

Zvinhu zve catheter

Makateta anonyanya kugadzirwa ne polyvinyl chloride, silicone, latex, etc. Macatheter akagadzirwa nezvinhu zvakasiyana ane maitiro akasiyana:

Polyvinyl chloride (PVC): chigadzirwa chacho chakanyanya kuoma, chinogumbura, chakasimba chekune dzimwe nyika kunzwa uye chisingadhuri, Ichi chigadzirwa hachina mabharuni uye hachina kupindirana ne biocompatible, chinowanzo kunamatira, uye chinogona kusiiwa kwenguva pfupi chete.

Rubber: chigadzirwa chacho chakapfava, chinowedzera kutsamwa, hachina kugadzikana kune varwere, uye chiri nyore kukonzera kuzvimba kwemucous membrane ye urethra.Zvakare zvakareruka kune calcium, asi isingadhuri uye kazhinji isina mabharumu.

Silicone: chigadzirwa chakapfava, chinenge chisina kutsamwisa, biocompatible uye hapana kunze kwemuviri kunzwa kune varwere.Iyo yakafara yemukati dhayamita yesilicone catheter inokodzera yepakati uye kwenguva refu yekugara catheterization, iyo inogona kudzivirira akawanda intubations, kuderedza friction ne urethra, kuderedza marwadzo emurwere uye kuderedza kuitika kwehutachiona hwehutachiwana.Nekudaro, iyo yepamusoro panguva yekugadzira maitiro haisi nyore kuchengetedza yakatsetseka.Iyo ine mutengo wakakwira, kazhinji isina mabharumu.

Latex: chigadzirwa chakapfava, biocompatible uye yakasununguka kune varwere.Iyo ine yakanyanya kutsetseka pamusoro, kushoma kushatirwa uye mutengo wakakodzera, mazhinji ane mabharumu, ayo ari nyore kune inwelling catheterization uye inogona kusiiwa munguva pfupi.Asi kunyorova kwelatex catheter kunoita kuti zviome kuisa zvakanaka mudundira, uye zviri nyore kunyura calcium blockage uye zvine cytotoxic reactions.

Single-lumen catheter: ine chiteshi chimwe chete, kazhinji isina mabharuni, haisi nyore kugadzirisa, uye inogona kusiiwa kwenguva pfupi chete.Inoda kugadziriswa nematepi paunenge uchishandisa.

Double-lumen catheter: ine maviri lumen, jekiseni lumen uye mvura yekubuda, iri nyore kugadzirisa, yakachengeteka uye isiri nyore kusvibisa.Inowanzoshandiswa mukugara kwe catheterization.

Three-lumen catheter: kune matatu lumen-mvura jekiseni lumen, drainage lumen uye mushonga jekiseni lumen, ayo anonyanya kushandiswa kwenguva pfupi inwelling catheterization, intravesical drug drip, flushing uye drainage.

Four-lumen catheter ine mabharumu maviri: catheter ine mabharumu maviri: bharumu rinomira nechekumberi rinovhara mutsipa wedundira;Bharumu rinovhara rinogadzikwa kumashure kuvhara urethra uye kugadzira mhango yakavharwa kuti iwane kurapwa kwemishonga yemuno.Iwo malume maviri ari kunze kwebharumu anobvumira kudiridza dundira.Iyo yakakosha kuchipatara kupfuura matatu-lumen catheter ine mabharumu maviri

Innovation yekugadzira nzira

Nekuenderera mberi kwekuvandudza tekinoroji yekugadzira, catheter yakaona shanduko kubva mukugadzirwa kwechinyakare, kugadzirwa kwemazuva ano, kusvika kuzere otomatiki kugadzirwa.Mazuva ano, kuwedzera uye kuwedzera otomatiki michina uye chaiyo midziyo inoshandiswa pakugadzira catheter.Kugadzira otomatiki hakungodzikisire mutengo wekugadzira uye kuwedzera tekinoroji level, asi zvakare inovandudza mhando yechigadzirwa, kuwedzera huwandu, uye inomhanyisa kusimudzira indasitiri.

Hengxingli otomatiki PVC catheter gungano midziyo inogona kuita otomatiki maitiro ese ekugadzira: otomatiki yekudyisa zvinhu uye kuburitsa zvigadzirwa zvakapedzwa, welding catheter matipi, kuunganidza zvinobatanidza uye kuyedza zvigadzirwa zvakapedzwa, ne 99% goho.Kuenderana kwayo kwepamusoro kunoibvumira kugadzirisa saizi yechigadzirwa uye kureba zvinoenderana nezvinodiwa.Chii zvakare, kuwanda kwekugovera maitiro kunogona kuita kuti chigadzirwa chiwedzere kunaka uye chakasimba;High-frequency welding head inobvumira sleeker catheter tips kuumbwa.

(Otomatiki PVC catheter musangano mudziyo)

Kuti isangane nezvinodiwa zvakasiyana zvekugadzira, Hengxingli silicone catheter balloons musangano muchina unogona kunyatso kuunganidza mabharumu uye kushandisa kupisa-shrinkable chubhu kupisa uye chimiro, kuitira kuti slop yechubhu iite mushe uye zvinobudirira kuvandudza kunyaradza kwechigadzirwa.Uye zvakare, kupfapfaidza kweglue kwakanyatso uye kwakafanana, uye mushure mekuwedzera kwebharumu, inogona kuve nechokwadi kuti concentricity yemuviri wecatheter uye bharumu inopindirana, iyo inonyatso chengetedza kunaka kwechigadzirwa uye inosimudzira kugadzirwa kwecatheter kuti irambe iripo. nenguva.
