Abstract

The utility model discloses a negative pressure flow guide device for mastectomy, comprising a flow guide leading-in pipe 1 and a negative pressure bottle 2. The negative pressure flow guide device for the mastectomy is characterized in that one end of the flow guide leading-in pipe 1 is fixed in a cavity after the mastectomy, and the other end of the same is connected with a glass pipe 3 to be inserted into a blood bottle 4; one side of a bottle cap of the blood bottle 4 is provided with a connection pipe 5 communicated with the negative pressure bottle 2; the middle of the bottle cap of the negative pressure bottle 2 is provided with a pressure ball 6, and one side of the pressure ball 6 is provided with an air suction pipe 7; and the air suction pipe 7 is connected with an air suction ball 8. Compared with the existing negative pressure bottle, the negative pressure flow guide device for the mastectomy not only has backflow prevention function, but also prompts the level of negative pressure, prevents the guiding flows from stropping and has unimpeded guiding flows.

Description

The mammectomy negative pressure drainage device

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of mammectomy negative pressure drainage device.

Background technology

At the mastectomy postoperative, for preventing the generation of complication, the general subcutaneous drainage catheter of putting adopts negative pressure bottle that the blood and slime of intracavity is flowed out.Above-mentioned drainage method, because of being simple and easy to promote, but also have following problem: one is one bottle of attraction, can not prevent that blood and slime from backflowing; The 2nd, the drainage time of postoperative is long, in the drain process, holds because of the negative pressure of negative pressure bottle is difficult to support, and often insufficient pressure causes drain to stop, and blood and slime can not be discharged continuously; The 3rd, the check valve pressure of inhaling in the ball is controlled by spring, and susceptiveness is poor, and fault is many, the phenomenon of inadequate drainage often occurs.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-function of backflowing that both had, and has the prompting vacuum magnitude to prevent that drain from stopping and the check valve unimpeded mammectomy negative pressure drainage device of drain that is active in one's movements again.

For reaching above purpose, technical solution adopted in the utility model is: this mammectomy negative pressure drainage device, constitute by drain ingress pipe, negative pressure bottle, an end that it is characterized in that the drain ingress pipe is fixed on postmastectomy intracavity, the other end connects glass tubing and inserts in the blood and slime bottle, establishes connection tube in bottle cap one side of blood and slime bottle and is communicated with negative pressure bottle, establishes pressure ball in the middle of the bottle cap of negative pressure bottle, one side is established suction nozzle, and suction nozzle and air-breathing ball join.This utility model is also implemented by following measure: described air-breathing ball, constitute by elastic sphere, breather cheek valve seat, air-breathing taper spool, exhaust check valve seat, aerofluxus taper spool, stepped hole, the elastic sphere upper end is connected with the breather cheek valve seat, lower end and exhaust check valve seat join, all establish stepped hole in breather cheek valve seat and exhaust check valve seat, air-breathing taper spool and aerofluxus taper spool are limited in the stepped hole.When using this utility model, one end of drain ingress pipe is fixed on postmastectomy intracavity, operates air-breathing ball then, make and form negative pressure in the negative pressure bottle, blood and slime flows in the blood and slime bottle under the effect of negative pressure, prevent that blood and slime from backflowing, when pressure ball rising that negative pressure bottle covers, show the negative pressure deficiency in the negative pressure bottle, need further air-breathing, operate air-breathing ball again, increase the negative pressure in the negative pressure bottle, prevent that drain from stopping.

The beneficial effects of the utility model are: compare with the negative pressure bottle of present use, not only have anti-function of backflowing, but also have the prompting vacuum magnitude, prevent that drain from stopping the advantage unimpeded with drain.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,2.This mammectomy negative pressure drainage device, constitute by drain ingress pipe 1, negative pressure bottle 2, an end that it is characterized in that drain ingress pipe 1 is fixed on postmastectomy intracavity, the other end connects glass tubing 3 and inserts in the blood and slime bottle 4, establishing connection tube 5 in bottle cap one side of blood and slime bottle 4 is communicated with negative pressure bottle 2, establish pressure ball 6, one sides and establish suction nozzle 7 in the middle of the bottle cap of negative pressure bottle 2, suction nozzle 7 joins with air-breathing ball 8.Described air-breathing ball 8, constitute by elastic sphere 8a, breather cheek valve seat 8b, air-breathing taper spool 8c, exhaust check valve seat 8d, aerofluxus taper spool 8e, stepped hole 8f, elastic sphere 8a upper end is connected with breather cheek valve seat 8b, lower end and exhaust check valve seat 8d join, all establish stepped hole 8f in breather cheek valve seat 8b and exhaust check valve seat 8d, air-breathing taper spool 8c and aerofluxus taper spool 8e are limited in the stepped hole 8f.
