Description

A kind of improved at the uniform velocity Lumbar catheter external drainage device

Technical field

The utility model relates to Encephalic drainage technical field, specifically a kind of improved at the uniform velocity Lumbar catheter external drainage device.

Background technique

Subarachnoid hemorrhage (subarachnoid hemorrhage, SAH) be clinical common cranial vascular disease it One, morbidity is an important factor for aggravating subsequent brain damage, case fatality rate is up to 25% suddenly, rapidly.It clinically generally adopts at present It is replaced with Lumbar puncture CSF and Lumbar cistern tube continuing drainage treatment is carried out using lumbar cistern drainage external member (as shown in Figure 1) SAH, the former need to puncture repeatedly, cause the damage and spiritual pain of patient site of puncture, and increase the work of medical staff Amount；And the latter then due in existing lumbar cistern drainage external member without regulating device, the control of drainage of cerebrospinal fluid amount and drainage speed, mesh It is preceding only to be controlled by setting liquid-collection bag with human body head relative height differential, this method because affected by many factors, if any Accidentally, it would be possible to cause Cerebrospinal Fluid in Patients drainage is excessively too fast hernia cerebri or intracranial hypotension syndrome occur.

Summary of the invention

It is improved at the uniform velocity to provide one kind for the shortcomings that the purpose of the utility model is to overcome existing Lumbar catheter external drainage devices Lumbar catheter external drainage device.

The utility model, including the first drainage tube, the second drainage tube, third drainage tube and liquid-collection bag, the first drainage tube are logical It crosses two connectors to connect with the second drainage tube, the three-way device and third drainage tube that the other end of the second drainage tube passes through belt switch The other end of connection, third drainage tube is connect by liquid-collection bag pipe fitting with liquid-collection bag, and improvements are drawn in the third Infusion pump is set in flow tube, and third drainage tube is adapted with infusion pump.

Infusion pump (also referred to as infusion measurement pump) is a kind of mature common therapy instrument, it by act on transfusion catheter ( Claim perfusion tube) achieve the purpose that control transfusion speed.It is usually used in the case where needing strict control amount of infusion and dose, is such as applying Boost drug, antiarrhymic drug, when venous transfusion of infantile or Intravenous Anesthesia etc..

Infusion pump is applied in lumbar cistern drainage device by the utility model, while will be by acting on leading for infusion pump For pipe using (or being changed to) perfusion tube compatible with infusion pump, this is a kind of technical solution the simplest and practical.

The utility model has the advantage that (1) since infusion pump is designed according to perfusion tube, in perfusion tube Liquid, which has, centainly to be pushed away suction and can accurately measure, so one section of drainage tube of lumbar cistern drainage external member is changed to (or connecting) infusion Pipe, then infusion pump is set on perfusion tube, have many advantages, such as at the uniform velocity to flow, accurately measure, avoid plugging, and connects simply, It is at low cost, it is clinical easy to operate.(2) amount of drainage of cerebrospinal fluid is not by the height of drainage bag, the Body Position Change of patient and moment encephalic The influence of the factors such as pressure raising, had both avoided the speed and amount that drainage of cerebrospinal fluid is influenced because of Body Position Change.It (3) can be according to encephalic The drainage of cerebrospinal fluid of pressure smoothly, safe, and cerebrospinal fluid adverse current can be prevented, the incidence of retrograde infection is reduced, improves and controls Treat the clinical efficacy and quality of life of patient.(4) can accurately according to intracranial pressure adjust drainage of cerebrospinal fluid speed and Amount.(5) reduce nursing work load, the progress of convenient nursing work, can accurately dynamic observation intracranial pressure variation.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of prior art lumbar cistern drainage external member；Fig. 2 is that the structure of the utility model embodiment is shown It is intended to.

In figure, the 1, first drainage tube；2, two connectors；3, the second drainage tube；4, the three-way device of belt switch；5, third is drawn Flow tube；6, liquid-collection bag；7, liquid-collection bag pipe fitting；8, infusion pump.

Specific embodiment

Referring to Fig. 2, a kind of improved at the uniform velocity Lumbar catheter external drainage device, including the first drainage tube 1, the second drainage tube 3, the Three drainage tubes 5 and liquid-collection bag 6, the first drainage tube 1 are connect by two connectors 2 with the second drainage tube 3, the second drainage tube 3 The other end is connect by the three-way device 4 of belt switch with third drainage tube 5, and the other end of third drainage tube 5 is connect by liquid-collection bag pipe First 7 connect with liquid-collection bag 6, and improvements are the setting infusion pump 8 on the third drainage tube 5, third drainage tube 5 and infusion Pump 8 is adapted.When using existing commercially available infusion pump 8, third drainage tube 5 is changed to existing perfusion tube, be allowed to it is existing defeated Liquid pump 8 is adapted；Or one section of existing perfusion tube is connected on third drainage tube 5, infusion pump 8 is arranged in perfusion tube It is upper.
