Abstract

The utility model discloses a disposable multifunction tracheal catheter. The closed profile at the front head with a tube joint(1) is provided with a catheter(2) with a through hole. The tracheal catheter is characterized in that the external wall of the catheter has a scale(4) for indicating the length and a back marking line(5) for marking the position. The utility model has the advantages that the scale(4) is capable of indicating the inserted depth of the catheter, and the back marking line(5) can display the direction and position when the front end of the catheter is inserted in the bronchia, in order to favor the doctor to confirm the position accurately and improve the reliability and success rate of intubatton treatment.

Description

A kind of disposable multifunction endotracheal tube

Technical field this utility model belongs to medical apparatus and instruments, is specially adapted to the endotracheal tube of respiratory system treatment.

The endotracheal tube that background technology is used at present, because it is slick soft plastic pipe, when operation technique, the doctor complete by rule of thumb with the trachea of estimating to the patient, insert conduit in the bronchus, when particularly in bronchus, plugging in conduit and since misjudgment with can not judge that the definite position (as left side, right side bronchus) of conduit causes intubation defeat, the waste that causes suffering and treat for the patient.The design people has proposed task of the present utility model after having carried out conscientious research for endotracheal tube for this reason, designs a kind of disposable multifunction endotracheal tube.

This disposable multifunction endotracheal tube of summary of the invention, it has the front end closed end of a pipe joint [1], the side has the conduit [2] of through hole, it is characterized in that having the scale [4] of expression catheter length and the dorsal part graticule [5] of marker location on the outer wall of this conduit.The utility model has the advantages that in operation process and can clearly be inserted into bronchial position by dorsal part graticule [5] indication conduit, whether the degree of depth by scale [4] indication conduit inserts arrives therapentic part with the judgement conduit.Use by scale and sign line can help the doctor to carry out location positioning accurately.Improve the reliability and the success rate of infusion therapy.Reduce in the therapeutic process because patient suffering and waste that intubation defeat causes.

Appended drawings 1 is a cutaway view of the present utility model, and accompanying drawing 2 is side views of accompanying drawing 1, and accompanying drawing 3 is that front end has slight curving structural representation.The expression meaning of sequence number in the accompanying drawings is: 1, joint, 2, conduit, 3, the hole, 4, scale, 5, graticule.

The specific embodiment is with reference to accompanying drawing, the disposable multifunction endotracheal tube, its front end closed end side with pipe joint [1] has the conduit [2] of through hole, it is characterized in that having the scale [4] of expression length and the dorsal part graticule [5] of marker location on the outer wall of this conduit.The material of conduit can use transparent plastic cement or plastic material, and scale can be recessed on tube wall, perhaps adopts the technology of colored materials admixture to make.The graticule of dorsal part [5] can adopt technology and/or the material identical with scale [4].For convenience operation can be designed to one section slight curving arc with about 1/10th places of the front end of conduit, makes the front end of conduit slightly upwarp, and the graticule of dorsal part is at the opposite face of arc of curvature, i.e. limit, left side in the accompanying drawing 3.Can further improve the accuracy of its sign.Scale interval for simplicity, can be provided with every 5 millimeters be a graduation mark, be beneficial to that user converts or use.The length of this conduit is with 45 ± 5～8 centimetres, and external diameter is advisable at 3.5～4.5 millimeters at 5.5～6.5 millimeters, internal diameter.The use summary is: for the patient who needs infusion therapy, intubate of the present utility model is inserted in patient's the trachea or bronchus, the degree of depth by the scale on it [4] indication insertion, promptly need the position of the focus for the treatment of or the position that needs are inhaled expectorant, determine the direction position of intubate by graticule [5], be unlikely to cause conduit wrong plug position (for example bronchial mistake in the left and right sides), then, just can carry out such as: inhale expectorant, oxygen supply in the lung, feeding drug into pulmones, various lungs such as air flue humidification, trachea, the treatment of bronchopathy is particularly suitable for such as the I respiratory failure type, lung abscess, multiple treatment of diseases such as lung cyst.

Claims

1, a kind of disposable multifunction endotracheal tube, its front end closed end side with pipe joint [1] has the conduit [2] of through hole, it is characterized in that having the scale [4] of expression length and the dorsal part graticule [5] of marker location on the outer wall of this conduit.
