Millar公司是固態(tài)微型壓力導(dǎo)管是一種導(dǎo)管式微型壓力傳感器帶有高精度固態(tài)壓力傳感器可直接通過插管的方式介入放置于信號源如左心室中高保真的記錄和分析有創(chuàng)壓力信號。
Millar Mikro-Tip® 導(dǎo)管是非常精確的生理壓力導(dǎo)管提供靈敏的壓力參數(shù)測量專門研究氣道壓力、椎管壓力或任一心血管壓力。
電生理導(dǎo)管可插入大小鼠等動(dòng)物的心臟內(nèi)部紀(jì)錄心房及心室的電生理信號傳導(dǎo)時(shí)間、不應(yīng)期、希氏束電位、竇房結(jié)和房室結(jié)功能、心律失常的誘導(dǎo)。
血壓測量導(dǎo)管
導(dǎo)管插入心腔后可直接測量不同部位的血壓數(shù)值更加準(zhǔn)確可靠廣泛用于心血管生理藥理研究。導(dǎo)管直徑有2F、3F、4F、5F、6F、7F部分規(guī)格如下
| 型號 | 材質(zhì) | 用途 | 尺寸F (1F = 0.33 mm) | 電極數(shù)量 | 長度 | 電極間距 |
| EPR-800 | Nylon and Polyimide | 少於25克之小鼠 | 1.1F (0.36 mm) | 8 | 4.5 cm | 1 mm |
| EPR-801 | Nylon and Polyimide | 小鼠 | 1.1F (0.36 mm) | 8 | 4.5 cm | 1 mm |
| EPR-802 | Nylon and Polyimide | 大鼠 | 1.6F (0.528 mm) | 8 | 12.5 cm | 1 mm |
與傳統(tǒng)的液體填充式PE導(dǎo)管相比這種新型壓力導(dǎo)管（傳感器）的優(yōu)點(diǎn)在于
(1)響應(yīng)頻率高壓力信號記錄完整波形無失幀特別適合于大小鼠心室壓的測量。
(2)無需液體填充信號無衰減
(3)無氣泡干擾的影響
(4)特殊工藝設(shè)計(jì)表面光滑硬度和柔韌度合適方便操作插管成功率高
(5)根據(jù)血管直徑的大小選擇合適的導(dǎo)管規(guī)格。從小鼠到大動(dòng)物尺寸1F到7F多種規(guī)格都可匹配。
壓力容積導(dǎo)管
壓力容積導(dǎo)管可以同時(shí)得到血壓和心室容積數(shù)值并繪制出壓力容積環(huán)從而進(jìn)一步評估心功能狀況。系統(tǒng)包括MILLAR P-V導(dǎo)管MPVS-300信號調(diào)節(jié)器,MP150數(shù)據(jù)采集系統(tǒng)PVAN軟件和計(jì)算機(jī)。導(dǎo)管外徑0.47-0.67 mm用于大鼠的SPR838為2F壓力容積導(dǎo)管兩對電極的間距是9mm有效長度12.5cm。用于小鼠的SPR839為1.4F壓力容積導(dǎo)管兩對電極的間距是4.5mm有效長度3.5cm。
We offers a minimally invasive octapolar (8 electrode) Electrophysiology Catheter for studying intracardiac electrical potentials in rodents. These unique EP Catheters allow for comprehensive analysis of potential propagation through the heart. Up to 4 intracardiac electrograms can be recorded simultaneously. The same Catheter can be used to pace the heart as well as record electrical activity.
