Description
Technical field
The utility model relates to medical drainage bag fields, more particularly, to the dedicated drainage bag of Lumbar catheter.
Background technique
Lumbar cistern drainage art is that drainage tube is placed in Lumbar catheter by one kind by lumbar puncture, is drained to cerebrospinal fluid
Treatment method, can both reduce intracranial pressure, can also by observation cerebrospinal fluid character, whether there is or not intracranial infections understanding, when necessary,
Therapeutic agent can also be injected to cavum subarachnoidale by drainage tube, relatively broad, effect affirmative is used in the nervous system disease.
Lumbar cistern drainage art has the advantages that wound is small, method is simple, success rate is high, can avoid puncturing repeatedly；It can continuous drainage
Blood contained cerebrospinal fluid reduces cerebral angiospasm and hydrocephalic incidence；And by the drainage to blood contained cerebrospinal fluid, accelerate cerebrospinal fluid
It generates, mitigates the stimulation of blood contained cerebrospinal fluid, promote the circulation of cerebrospinal fluid, alleviate cerebral angiospasm, improve cerebral ischemic condition；And it can
Sampling carries out cerebrospinal fluid laboratory examination at any time, and dynamic observation cerebrospinal fluid character is to understand encephalic situation.
It is at present on the market usually the dedicated drainage bag with Lumbar catheter to complete the drainage work of Lumbar catheter, existing draws
Stream scheme is generally two kinds, and one is drawn with the epidural catheter of caudal anaesthesia and its included connector with commonly medical
The shortcomings that stream bag linking, this scheme is to connect not closely, easily falls off, drainage tube is caused to pollute, and increase infection risk；It is another
It kind is using dedicated lumbar cistern drainage device, the shortcomings that this scheme is: 1. conduit materials are too soft, need wire guide when setting pipe
Lead into intraspinal tube, it is inconvenient, set pipe success rate it is not high and increase neurotrosis risk；2. being with drainage bag connection type
It is inserted by a metal joint in soft conduit, is easy to cause conduit break-through and link is not close, be easy de- pipe, equally cause
Drainage tube pollution, and increase infection risk.3. expensive.
Moreover, drainage scheme on the market has that one is not easy to ignore, it is exactly plugging, plugging tends to occur
24 hours after surgery, or even occur within a few hours.Main cause is that encephalic blood clot deposits plugging in waist pond, in addition encephalic
Necrotic brain tissues and infection focus are deposited on drainage tube head end blocking duct, are also to drain not there are also folding at drainage tube puncture point
Unobstructed reason；The problem of for plugging, above-mentioned two schemes deal with it is all very inconvenient, be required to disconnect drainage bag with
The connection of drainage tube, then washing pipe is carried out, increase a possibility that patient infects.

Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
It is described as shown in Figure 1 to Figure 4, a kind of dedicated drainage bag of Lumbar catheter, including sequentially connected drainage bag ontology 1, drainage group
Part 2, piercing assembly 3；The drainage bag ontology 1, drainage component 2, piercing assembly 3 are sequentially connected；Since piercing assembly 3 is existing
Routine techniques, in order to avoid narration burden, be just not described in detail here；Drainage bag ontology 1 is equipped with graduation mark, can be very
Total liquid volume in convenient observation drainage bag；Drainage component 2 includes the first drainage tube 21, the second drainage tube 22, detachable
Syringe needle 23 and connector 24；First drainage tube 21 and the second drainage tube 22 are connected with the both ends of connector 24 respectively；Even
The inside of connector 24 is equipped with a connexon 25, and the second drainage tube 22 passes through connexon 25 and is fixed on inside connector 24；The needle
In first 23 dismountable piercing connexons 25；Cylindrical cavity is equipped with inside syringe needle 23, the diameter of the internal cavities of syringe needle 23 omits
Greater than the outer diameter of the second drainage tube 22, the second drainage tube 22 can so freely moved in needle wall.
Connector 24 includes the first connector 241 and the second connector 242 that can mutually dismantle；First connector, 241 He
Second connector 242 is the environmentally-friendly plastic of hard, and one end of the first connector 241 is fixedly connected with the first drainage tube 21, the
One end of two connectors 242 is fixedly connected with connexon 25；The other end of first connector 241 is equipped with internal screw thread, the second connection
First 242 other end is equipped with external screw thread corresponding with the first connector 241, and they can mutually be screwed by screw thread.
Connexon 25 is made using solid rubber, cylindrical, length 10mm, and diameter 7mm possesses
Elasticity well, connexon 25 is fixed to be sealed in inside the second connector 242, is placed into second when syringe needle 23 is pierced into rubber
After drainage tube 22, syringe needle 23 is extracted, rubber automatically can be tightened to 22 surface of the second drainage tube due to the elasticity of itself, so that the
Two drainage tubes 22 and 25 opposing seal of connexon and it is capable of fixing the second drainage tube；One end of second drainage tube 22 exceeds connexon
10~15mm can guarantee that the end of the second drainage tube 22 will not enter connexon 25 in this way, ensure that the smooth of the second drainage tube 22
It is logical.
First drainage tube 21 is equipped with is it possible that formula dropper 211, described is it possible that formula dropper 211 is close to connector, structure was both
The flow of hydrops can be very easily observed, washing pipe can also be carried out to the place of plugging.When plugging phenomenon occurs for drainage bag
When, if the part of plugging present in the second drainage tube 22, can fold for the first drawing at drainage bag ontology 1 of drainage tube 21
Flow tube realizes pair the closing is it possible that 211 one end of formula dropper, then squeezes is it possible that formula dropper 211, realize to the second drainage tube 22
Washing pipe；Similarly, if the part of plugging is present in the first drainage tube 21, the second drainage tube 22 is folded at drainage bag ontology 1
Position, realize pair the closing is it possible that 211 one end of formula dropper, then squeeze is it possible that formula dropper 211, realize to the first drainage tube 21
Washing pipe.
For second drainage tube 22 using the epidural catheter that can be placed in Lumbar catheter, it is 1mm that this conduit, which selects diameter,
Lumbar vertebrae is pierced into from human body back by the piercing assembly of front end when in use, and is placed in Lumbar catheter, to cerebrospinal fluid into
Row drainage.
The internal diameter of second connector 242 is identical as the outer diameter of syringe nipple, is 4mm, when needing collect specimen or fiber crops
When liquor-saturated teacher needs to inject drug into lumbar vertebrae, the screw thread of connector 24 can be opened, syringe nipple is inserted into the second connection
