CN2657136Y - Special model for thoracocentesis training - Google Patents

Abstract

The utility model provides a special model that is used in thorax puncture training, which is characterized in that a flexible shell that is in the shape of human thorax and can be filled with liquid is made from latex and polyethylene foam material, and is lined inside with a stimulating rib skeleton of human thorax. The model solves the problem of a lack of thorax puncture training apparatuses in hospitals and medical schools, and reduces the tension of trainees because of unskillful clinical operation. Additionally, the utility model has the advantages of durability and low cost.

Description

A kind of thoracentesis training special purpose model

Technical field

The utility model relates to a kind of medical science model, especially a kind of thoracentesis training special purpose model.

Background technology

MED in present many hospitals or the clinician who has just worked, owing to lack clinical experience, carry out to produce nervous psychology in the thoracic drainage and thoracentesis surgical procedure for the first time, cause operation technique inaccurate, even produce iatrogenic pneumothorax, situation such as hemorrhage, patient's treatment there is harmful effect.Tracing it to its cause is owing to there is not the medicine equipment of thoracentesis exercise, thereby lacks the training on operation of prior thoracentesis.

Summary of the invention

The utility model provides a kind of thoracentesis training special purpose model of being convenient to practise for solving the technical matters that exists in the known technology.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

A kind of thoracentesis training special purpose model, but the lid that is the flexible closure casing of the filling liquid of human body thorax shape, liquid injection hole that housing top has filling liquid and sealing liquid injection hole by the profile that organic material is made is formed, it is characterized in that: the wall thickness of described housing constitutes by three layers, its extexine is the thick latex material layer of 1mm, its middle layer is the thick polyethylene foam material layer of 10mm, and its endosexine is the latex material layer of 3-5mm; The framing of the simulation thorax that is made of plastics also is installed in the described housing, and each frame spacing is 10mm.

The utility model can also adopt following technical measures:

The lid of described sealing liquid injection hole is a circular cork.

The lid of described sealing liquid injection hole is one and has the vinyl cover that externally threaded cross section is the T type, also is shaped on the internal thread that the external thread with vinyl cover is complementary in the described liquid injection hole.

Advantage and the good effect that the utlity model has are: but since adopt latex and polythene material make profile be the human body thorax filling liquid flexible shell and the framing of the simulation thorax of plastics is installed in housing, consistent with the anatomical physiology structure of human body thorax like this, replaced actual human body fully, be convenient to doctor's repeatable operation exercise of MED and new work, make them grasp the technical ability of thoracentesis operation easily, especially puncture in proper order, in addition, the utility model also has durable in use and the low advantage of cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a housing wall sectional drawing of the present utility model;

Fig. 3 is the another kind of structural representation of lid of the present utility model.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, for the practitioner who makes thoracentesis has sensation more really, flexible closure casing 1 is made simulation human body thorax shape, and simulation humanbody thorax framing 2 is installed in housing, and each frame spacing is 10mm.Have theliquid injection hole 4 of perfusion fluid on housing top, be closed withcork 3 on the liquid injection hole.Housing top also can have theliquid injection hole 6 of screw thread, and it is the band coupling threaded plastic lid 5 of T type that the cross section is housed in the threaded hole, reaches the purpose of sealing liquid injection hole equally, as shown in Figure 3.In order to make flexible shell that better human muscle's sensation be arranged, the wall thickness of housing is made of trilaminate material; Extexine is the thick emulsion layer of 1mm (skin layer) 11, and the middle layer is the polyethylene foam material layer (muscle layer) 12 of 10mm, and the endosexine is the thick emulsion layer of 3～5mm (pleura layer) 13, so more near actual human body, the practitioner is had better effect.

Using method:

1. from liquid injection hole tight cork of filling liquid bonnet in housing;

2. local anaesthesia: in syringe, adorn liquid, simulation hypodermic injection, the withdraw of the needle after inserting needle injection on the housing;

3. select the intercostal space of housing, inserting needle then is by " skin ", " muscle " and " pleura " (practitioner feels significantly);

4. the liquid (simulation pleural effusion) in the extraction housing;

5. extract out and extract syringe (because the characteristic pin hole of latex material not can overflowing liquid) after the desired liquid measure.

Claims (3)

1. thoracentesis training special purpose model, but the lid that is the flexible closure casing of the filling liquid of human body thorax shape, liquid injection hole that housing top has filling liquid and sealing liquid injection hole by the profile that organic material is made is formed, it is characterized in that: the wall thickness of described housing constitutes by three layers, its extexine is the thick latex material layer of 1mm, its middle layer is the thick polyethylene foam material layer of 10mm, and its endosexine is the latex material layer of 3-5mm; The framing of the simulation thorax that is made of plastics also is installed in the described housing, and each frame spacing is 10mm.

2. a kind of thoracentesis training special purpose model according to claim 1 is characterized in that: the lid of described sealing liquid injection hole is a circular cork.

3. a kind of thoracentesis training special purpose model according to claim 1, it is characterized in that: the lid of described sealing liquid injection hole is one and has the vinyl cover that externally threaded cross section is the T type, also is shaped on the internal thread that the external thread with vinyl cover is complementary in the described liquid injection hole.
