The present invention provides a hollow tube for sputum suction, comprising: the pipe comprises a pipe body, wherein one end of the pipe body is provided with a negative pressure joint; the other end of the tube body is left empty as a suction end; a plurality of suction holes are formed in the part, close to the suction end, of the pipe body wall; and a small hole is formed in the part, close to the negative pressure joint, of the pipe body. Preferably, in the vacuum tube for sputum aspiration, the part of the tube body close to the negative pressure joint is provided with two small holes which are penetrated oppositely. Preferably, in the vacuum tube for sputum aspiration, the aperture of the small hole is 3 mm. Compared with the prior art, the utility model has simpler and more convenient operation, has less influence on the respiration of a patient and prolongs the service life of the hollow tube.

Description

Hollow tube for sputum suction

Technical Field

The utility model relates to a medical instrument, in particular to a hollow tube for sputum suction.

Background

Sputum suction is a common medical aid measure, and a sputum suction hollow tube is a medical device commonly used for sputum suction. The existing sputum suction hollow tube structure is shown in figure 1 and comprises a flexible tube body 1, and the length of the tube body is usually 50-55 cm. One end of the pipe body 1 is a negative pressure joint 2 which is used for connecting negative pressure equipment. The other end of the tube body 1 is reserved with a space as a suction end 3, and the tube body 1 is provided with a plurality of suction holes 4 (only one hole is shown as an illustration in figure 1) at the part close to the suction end 3.

When the device is used, the negative pressure connector 2 is connected to a negative pressure device (not shown), then the suction end 3 is inserted into the trachea of a patient, and sputum in the trachea and sputum attached to the trachea wall can be sucked out from the suction end 3 and the suction hole 4 respectively.

The sputum suction operation is intermittent and cannot always suck air from the trachea of a patient, because the respiration of the patient is seriously influenced, particularly, the patient needing the sputum suction measure is often a serious and unconscious patient, and the continuous suction of air in the trachea can even cause the life risk of the patient. The operation of inserting the tube body 1 into the trachea of the patient is not only complicated, but also causes extreme discomfort of the patient in the inserting process, so that the tube body is kept in the trachea of the patient after being inserted once in practice, and when sputum suction is not needed, the part of the tube body 1 close to the negative pressure joint is folded in half, so that the negative pressure of the suction end 3 disappears; when sputum suction is needed, the tube body 1 is recovered.

This practice of the prior art has the disadvantages: firstly, the folding of the tube body 1 can not completely eliminate the negative pressure at the suction end 3, but can also have some influence on the breathing of the patient. Secondly, the continuous doubling over also seriously influences the service life of the pipe body 1. Finally, the operations of folding and fixing are also complicated.

SUMMERY OF THE UTILITY MODEL

In view of the above-described drawbacks of the prior art, an object of the present invention is to provide a hollow tube for sputum suction, comprising: the pipe comprises a pipe body, wherein one end of the pipe body is provided with a negative pressure joint; the other end of the tube body is left empty as a suction end; a plurality of suction holes are formed in the part, close to the suction end, of the pipe body wall; and a small hole is formed in the part, close to the negative pressure joint, of the pipe body. Preferably, in the vacuum tube for sputum aspiration, the part of the tube body close to the negative pressure joint is provided with two small holes which are penetrated oppositely. Preferably, in the vacuum tube for sputum aspiration, the aperture of the small hole is 3 mm.

As mentioned above, compared with the prior art, the utility model has the advantages of simpler operation, less influence on the respiration of a patient and prolonged service life of the hollow tube.

Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.

Please refer to the attached drawings. It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.

Reference is first made to fig. 2. Fig. 2 is a schematic view of an embodiment of the present invention, and the same parts as those in the prior art are also denoted by the same reference numerals in fig. 2 for convenience of explanation. The improvement of the utility model over the prior art is that: the part of the pipe body 1 close to the negative pressure joint 2 is provided with a small hole 5. Thus, under normal conditions (when sputum suction is not needed), air can flow into the tube body 1 from the small hole 5, so that negative pressure does not exist at the suction end 3, and the breath of a patient is not influenced. When the suction end 3 needs negative pressure (namely when sputum is sucked), the small hole 5 only needs to be blocked temporarily, and the suction end 3 and the suction hole 4 can generate negative pressure, so that the sputum sucking function is realized. Therefore, the operation of folding the tube body 1 in half is avoided, and the operation of temporarily blocking the small hole 5 can be even completed by the fingers of medical personnel due to less time and short duration of sputum suction, so that the operation is simple and easy, and no excessive burden is caused. If the size of the small hole 5 is too small, the air quantity flowing into the tube body 1 through the small hole 5 is insufficient, and the suction end 3 still has negative pressure to influence the breathing of the patient; if aperture 5 enlarges, be favorable to reducing the influence of negative pressure to absorbing end 3, nevertheless if hole 5 is opened too big, influence the intensity of shaft of pipe 1 on the one hand, come to bring the degree of difficulty for the operation of blockking up the aperture, through the experiment, the diameter of aperture 5 can compromise the toughness of shaft of pipe 1 and the easy operability of blockking up aperture 5 when 3 mm. More preferably, two through holes 5 (as shown in fig. 2, the two through holes 5 are through up and down) may be provided at a portion of the tube body 1 close to the negative pressure connector 2, which not only increases the opening area of the holes 5, but also facilitates the medical staff to use the thumb and the forefinger to pinch and block the two holes 5 to complete the sputum suction operation.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
