Abstract

The utility model discloses a chest drainage tube. The chest drainage tube comprises a drainage tube, wherein a metal thread is arranged at the head end of the drainage tube; and a metal soft head with holes is arranged on the top of the metal thread. When the chest drainage tube is used, the metal soft head is deflected and the chest drainage tube is inserted into the deep part of a chest through a small hole on a chest wall; through unique design of the metal soft head with the holes, the chest drainage tube is guaranteed to be positioned at a lowest position always, so that blood in the chest can be effectively sucked out; through design of multiple holes, the blockage of the drainage tube can be effectively avoided; the chest drainage tube is made of a medical chest drainage tube, so that the foreign body reaction is small; and an end interface can be matched with an extracorporeal circulation pipeline and a chest drainage bottle pipeline and can be used for intraoperative and postoperative drainage, without a special external interface, so that the chest drainage tube is convenient and quick to use.

Description

Intrathoracic drain

Technical field

This utility model relates to a kind of medical apparatus and instruments, more specifically, uses when relating to the operation of a kind of minimally invasive heart and the intrathoracic drain of postoperative drainage.

Background technology

In cardiac thoracic surgery, need to use intrathoracic gas of chest drainage Tube Drain or liquid at present; Existing thoracoscope operation on heart is processed by medical plastic with intrathoracic drain; Usually float during use in light weight, and material hardness is low receives the external force bending easily, in case the drain tube head blocks or the pipe bending when negative pressure is excessive; Promptly influence in the art and the postoperative drainage effect, increase the risk that post-operative complication takes place greatly.Clinically need cooperate special-purpose plastics or glass connector to mate at present with corresponding pipeline with the breast skirt, not convenient during use.Medical treatment patent documentation CN2621707Y discloses a kind of intrathoracic drain that is provided with fixed sleeving, reaches fixed effect through the form that increases a positioning disk, though can make drainage tube fix inconvenient operation in the operation.

The medical polyurethane that this drainage tube uses, have good rub resistance wearing and tearing, outstanding tearing strength and anti-puncture can, high hydrolysis resistance can and antibiotic pollution capacity.Have characteristics such as excellent biological compatibility, excellent mechanical property, easy-formation processing because of it; Increasingly extensive in purposes medically in recent years, be applied in fields such as wound dressing agent, weaving coating, test tube, conduit, packing film and artificial hearts at present.

Summary of the invention

This utility model technical problem to be solved is, provides a kind of drainage tube head end to be positioned at the lowest part in thoracic cavity, the intrathoracic drain of sucking-off thoracic cavity inner blood effectively all the time.

In order to address the above problem, this utility model provides a kind of intrathoracic drain, comprises drainage tube, the head end of drainage tube be provided with one section metal threaded, there is the soft head of perforated metal on metal threaded top.

Said drainage tube material is used the medical grade polyurethane material.

The advantage of this utility model is that the intrathoracic drain of this utility model is easy to use, material have the wearing and tearing of good rub resistance, outstanding tearing strength and anti-puncture can, high hydrolysis resistance can and antibiotic pollution capacity.During use that metal is first partially; Insert the deep, thoracic cavity through the thoracic wall aperture; The soft head design of its unique band porous metals gravitate can guarantee that thoracic cavity stream pipe is positioned at the lowest part in thoracic cavity all the time; The intrathoracic blood of sucking-off effectively, its porous design can effectively avoid drainage tube to block, and drain can keep clear during continuous negative pressure suction.Metal threadedly can prevent that the endogenous cause of ill patient body position changes and bending takes place influence drainage effect drainage tube in the thoracic cavity, end interfaces can be mated with extracorporeal circulation pipeline and thoracic cavity drainage bottle pipeline, need not external particular interface, and is easy to use.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is elaborated, the purposes of embodiment only is to explain the present invention and non-limiting technical scheme.

Embodiment 1, intrathoracic drain

As shown in Figure 1, a kind of intrathoracic drain, the head end of drainage tube 3 be provided with one section metal threaded 5, there is soft 1 of perforated metal on metal threaded 5 tops, an aperture is established at center, soft 1 top of said metal, communicates with drainage tube head end aperture, makes things convenient for drain.On soft 1 on the metal a plurality of apertures 2 are set also, can effectively avoid drainage tube to block.Drainage tube end interfaces 4 is identical with conventional drainage tube, can mate with extracorporeal circulation pipeline and thoracic cavity drainage bottle pipeline, need not external particular interface, and is easy to use.During use that soft 1 one on metal is inclined to one side; Insert the deep, thoracic cavity through the thoracic wall aperture; The soft head design of its unique perforated metal can guarantee intrathoracic drain insert the thoracic cavity after gravitate make thoracic cavity stream pipe tube head be positioned at the lowest part in thoracic cavity all the time; The intrathoracic blood of sucking-off effectively, its porous design can effectively avoid drainage tube to block.Metal threaded 5 are about 4 centimetres at least, can prevent that the endogenous cause of ill patient body position changes and bending takes place influences drainage effect drainage tube in the thoracic cavity.

The whole material of drainage tube is used the medical grade polyurethane material, and the surface can be provided with graduation mark, grasps the degree of depth that drainage tube is inserted the thoracic cavity, is convenient to adjust the position of placement.This drainage tube is placed special technique and the instrument of need not simple to operate, can be used in the heart art and the thoracic surgery postoperative drainage.

The above only is the preferred implementation of this utility model, should be pointed out that for those skilled in the art; Under the prerequisite that does not break away from this utility model principle; Can also make some improvement and retouching, can also be a coil spring or a circle thrust such as the soft head of perforated metal, near top end one circular thrust arranged at conventional drainage tube head end metal spring; Increase spring weight, also strengthen drainage effect.These improvement and retouching also should be regarded as the protection domain of this utility model.

Claims (1)

1. an intrathoracic drain comprises drainage tube, it is characterized in that, the head end of drainage tube be provided with one section metal threaded, there is the soft head of perforated metal on metal threaded top.
