Description

Disposable proctoscope with light source

This utility model belongs to medical apparatus and instruments, is a kind of disposable rectoscope with light source.

Traditional rectoscope is a kind of metal medical appliance that uses repeatedly of not being with light source, its major defect is: do not have the illumination device 1., must add the light source facility during clinical use, these light source facilities be not heavy, complicated, loaded down with trivial details, price is expensive, just is to use inconvenience; 2. because this apparatus is repeatedly to use repeatedly, might cause nosocomial infection, as infectious disease such as property contagious disease (acquired immune deficiency syndrome (AIDS), gonorrhea etc.) and hepatitis B.In recent years, the unit that has has also produced disposable rectoscope device, but does not have the all-in-one-piece illuminator that is complementary, and still need add the light source facility.

The purpose of this utility model is to avoid above-mentioned shortcoming, proposes the disposable rectoscope of a kind of band light source, and its illuminator also can be done the daily inspection people that diagnoses a disease for each doctor of section and uses.

The purpose of this utility model reaches by following measure: this utility model comprises rectoscope inner core and rectoscope shell, also have a flashlight type to use interior specula as handle and illumination more, lid is arranged at many fore shell tops with interior specula, the T-shape joint tongue is arranged at the bottom, have a link slot on the tubaeform mirror edge of rectoscope shell, how with the joint tongue of interior specula with become detachable one after the link slot of rectoscope shell engages.

Below in conjunction with the embodiment accompanying drawing this utility model is described in further detail:

Fig. 1 is a cross-sectional schematic of the present utility model;

Fig. 2 for many A with interior specula among Fig. 1 to partial schematic diagram (not closing the lid);

Fig. 3 is many cross sectional representation that engages with loam cake, rectoscope shell with interior specula fore shell of the present utility model;

Fig. 4 is a rectoscope shell vertical view of the present utility model.

Among the figure, (1) rectoscope shell, (2) rectoscope inner core, (3) loam cake, (4) switch, (5) use interior specula more, (6) back cover, (7) bonnet, (8) fore shell, (8a) lamp bracket seat, (9) bulb, (10) bulb top conducting strip, (11) bulb sleeve electricity sheet, (12) slide plate, (13) lead, (14) lug plate.

How to make with aluminium alloy with the back cover (6) and the bonnet (7) of interior specula (5), in adorn two the joint No. 7 batteries; Fore shell (8) and loam cake (3) are made with ABS plastic, and fore shell (8) is connected with screw thread with back cover (6).One is with it arranged in the fore shell (8), have the lamp bracket seat (8a) of two grooves, bulb top conducting strip (10) and the bulb sleeve electricity sheet (11) made with metal (as copper sheet) are embedded in respectively in two grooves of lamp bracket seat (8a), bulb sleeve electricity sheet (11) often contacts with the slide plate (12) of switch (4), and lead (13) two is connected on respectively on bulb top conducting strip (10) and the lug plate (14).Adopt 2.2～3.0 volts of pea lamps.Fore shell (8) has seam to match with loam cake (3) edge, and loam cake (3) stop portion also has little raised line and the corresponding recess of fore shell (8) to interlock.Loam cake (3) is with after fore shell (8) combines, and loam cake (3) is the attitude that tilts to the front lower place, and the silvery reflection material is posted in loam cake (3) inwall front portion, to increase visual field illumination.The T-shape tenon is arranged at fore shell (8) bottom.The structure of rectoscope part is a traditional type, comprises shell (1) and inner core (2), does not have handle on the tubaeform mirror edge of shell (1), and for one of bar open slotted arm, groove is opened to the mirror edge.Inner core (2) and shell (1) are made with medical polyvinyl or medical high-density polyethylene material, and inner core (2) head is made the shell shape.How with the groove on the T-shape tenon of interior specula (5) and the rectoscope shell (1) mutually behind the fit, the rectoscope part has just become detachable one with the interior specula of many usefulness (5), many operating positions with interior specula (5) irradiation mouth are positioned at rectoscope and spy on aperture edge, as shown in Figure 1.In the use, in the time will from rectoscope shell (1), extracting inner core (2) out, will use interior specula (5) to remove backward more, just can avoid how contaminated with interior specula (5).Open loam cake (3), (9) easily can more change the bulb.

This utility model is rational in infrastructure, uses simple, convenient, safety, reliable, easy to carry, and the disease medical cross infection that can keep off infection, and how the disposable use of rectoscope part can repeatedly and separately be used with interior specula.
