Problems solved by technology

However, in the current examination and treatment process, a set of catheters will be used for bronchoalveolar lavage and drug injection. If the patient needs to be brushed for inspection after lavage instead of drug injection, the lavage catheter needs to be taken out, and another set of brushing inspection should be taken. Examination with the catheter used increases the treatment cost and economic burden of the patient

Embodiment 1

[0036] like figure 2 and 6 As shown, in this embodiment, a through cavity 21 is provided in the inner tube 2, and the through cavity 21 is used as a lavage channel, a medicine injection channel or a brush delivery channel according to the needs of diagnosis and treatment. In the case that the interface of the irrigation equipment and the medicine spraying equipment are the same, the connection interface 5 of the present embodiment is provided with two inlets, which are respectively the brush feeding inlet 51 and the irrigation inlet (medicine spraying inlet) 52; The hairbrush feeds into the tunnel (through cavity 21) and is connected in a straight line, which facilitates the brush 7 to pass in and out. The brush feeds into the tunnel (through the cavity 21);

[0037] like Figure 4 As shown, this embodiment also includes an anti-pollution plug 6 . When the through-cavity 21 is used as a brush into the channel, the anti-pollution plug 6 is used to plug the outlet end of the...

Embodiment 2

[0042] like Figure 7As shown, in this embodiment, two independent through-cavities are provided in the inner tube 2, the irrigation channel and the injection channel share one through-cavity, and the brush feeding channel corresponds to the other through-cavity. All the other structures are the same as in Embodiment 1.

Embodiment 3

[0044] like Figure 8 As shown, in this embodiment, the inner tube 2 is provided with three independent through-cavities, and the lavage channel, drug injection channel and brush feeding channel correspond to one through-cavity respectively. All the other structures are the same as in Embodiment 1.

Abstract

The invention discloses a balloon catheter assembly for bronchoscope. The balloon catheter assembly comprises a hairbrush for brush biopsy, an inner catheter used for conveying lavage fluid, medicinefluid and the hairbrush from the external portion to a target bronchus, and an outer catheter which sleeves the inner catheter and is provided with a balloon. The outer catheter is in sealing connection with the inner catheter so that a sealed space can be formed between the inner catheter and the outer catheter, and the balloon can be inflated, wherein the outer catheter is communicated with an air inflation pipe. The inner catheter is provided with a lavage channel, a medicine injection channel and a hairbrush send-in channel, wherein two ends of the lavage channel are penetrating, the lavage channel is used for conveying the lavage fluid, the medicine injection channel is used for conveying the medicine fluid, and the hairbrush send-in channel is used for conveying the hairbrush. An anti-polluting plug used for blockwork is arranged at the outlet end of the hairbrush send-in channel. The balloon catheter assembly is used for bronchoalveolar lavage, medicine injection and hairbrush biopsy of the bronchus, improves the treatment efficiency and reduces the economical burdens of patients.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bronchoscopic balloon catheter assembly. Background technique [0002] Bronchoscopy is a commonly used means of examination and treatment in respiratory medicine. Using a catheter to lavage and brush the bronchoalveolar under the bronchoscope is a common inspection item at present, and using a catheter to inject medicine to the bronchoalveolar under the bronchoscope is the most commonly used treatment at present. method. However, in the current examination and treatment process, a set of catheters will be used for bronchoalveolar lavage and drug injection. If the patient needs to be brushed for inspection after lavage instead of drug injection, the lavage catheter needs to be taken out, and another set of brushing inspection should be taken. Examination of the catheter used increases the patient's treatment costs and economic burden. Contents of the invention ...
