Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical supplies, in particular to an artificial respiration isolation mask for distinguishing the front and back sides. Background Art
[0002] At present, during cardiopulmonary resuscitation training, it is necessary to use a manikin for practical exercises, and the training content mainly includes cardiac compression and artificial respiration. When conducting artificial respiration training, in order to avoid cross infection, a respiratory isolation mask will be placed between the trainee and the manikin; to avoid waste, usually one respiratory isolation mask will be issued to each trainee in each training course, and the respiratory isolation mask may be used multiple times in the same course. The existing respiratory isolation mask is generally composed of a plastic film and a double-layer dustproof cloth, and the dustproof cloth is thermoformed on the plastic film. The double-layer dustproof cloth plays the role of isolating saliva, air filtering, and preventing penetration. Since the front and back of the plastic film are both transparent and there are no obvious features to distinguish the front and back, many trainees are nervous and it is easy to ignore the front and back during training exercises. During multiple exercises, it is easy to cover the side that may contain saliva on the face of the manikin. During the next trainee's practice, because the front and back of the respiratory membrane are ignored, they will come into contact with the saliva of other trainees that previously remained around the simulated population; increasing the risk of cross infection, it is very necessary to improve it. Summary of the invention
[0003] The purpose of the utility model is to provide an artificial respiration isolation mask for distinguishing the front and back sides in view of the deficiencies in the above-mentioned prior art, which has the characteristics of being able to easily distinguish the front and back sides, thereby avoiding mutual infection between trainees.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an artificial respiration isolation mask for distinguishing the front and back sides, including a plastic film and a breathing filter cloth, wherein a vent is opened on the plastic film, and the breathing filter cloth is arranged on the vent; the front and back sides of the plastic film are respectively printed with identification coatings of different colors.
[0005] The plastic film is formed with a three-dimensional raised portion that matches the nose of the training simulator. The inner concave surface of the three-dimensional raised portion is located on the reverse side of the plastic film, and the raised surface is located on the front side of the plastic film.
[0006] The breathing filter cloth is composed of a hydrophobic layer, a filter layer and a water absorbing layer from the outside to the inside.
[0007] The marking coating covers the film area of the plastic film.
[0008] The upper end surface and the lower end surface of the breathing filter cloth are marked with different colors.
[0009] After adopting the above structure, the advantages of the utility model compared with the prior art are: the front and back sides of the plastic film of the utility model are marked with coatings of different colors, so that the front and back sides can be effectively identified during use, avoiding the occurrence of cross-infection of trainees due to misuse of the back side; the three-dimensional protrusion on the plastic film can fit the simulated human nose, so as to facilitate the alignment of the breathing filter cloth with the simulated human oral position, and at the same time, such a structure is also convenient for identifying the front and back sides of the plastic film; the breathing filter cloth is composed of a hydrophobic layer, a filter layer and a water-absorbing layer, and this structure further reduces the risk of cross-infection. In addition, the different color markings on its upper end face and lower end face are also conducive to the identification of the front and back sides. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a side structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0012] The following description is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention. The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0013] For example, see Figure 1 and Figure 2As shown: an artificial respiration isolation mask for distinguishing the front and back sides, including a plastic film 10 and a breathing filter cloth 11. The plastic film 10 is generally the size of the plane of the simulated person's head; a vent is opened on the plastic film 10, and the position of the vent corresponds to the position of the mouth of the simulated person. The breathing filter cloth 11 is thermoformed on the vent. In use, the position of the breathing filter cloth 11 is matched with the position of the simulated mouth. The breathing filter cloth 11 is composed of a hydrophobic layer, a filter layer and a water-absorbing layer from the outside to the inside. The hydrophobic layer and the water-absorbing layer are generally made of non-woven fabric materials, and the filter layer is generally made of melt-blown fabric materials; the hydrophobic layer will contact the mouth of the simulated person in use, and the water-absorbing layer will contact the mouth of the trainee to achieve a filtering effect. At the same time, since the outer layer is a hydrophobic layer, it is located on the back of the plastic film 10, so the front and back of the plastic film 10 can also be distinguished by the hydrophobic layer. The upper end face and the lower end face of the breathing filter cloth 11 are marked with different colors. Specifically, the hydrophobic layer and the water-absorbing layer are in different colors, so the front and back sides can also be identified by color. The front and back sides of the plastic film 10 are respectively printed with marking coatings 12 of different colors, and the marking coatings 12 cover the film area of the plastic film 10. Of course, it can also only cover the partial film area of the plastic film 10; specifically, when the front marking coating 12 of the plastic film 10 is a blue coating, the back marking coating 12 can be yellow or green or other non-blue coatings to effectively distinguish. A three-dimensional raised portion 13 is molded on the plastic film 10 to match the nose of the simulated person. When in use, the inner concave surface of the three-dimensional raised portion 13 is located on the back side of the plastic film 10, and the raised surface is located on the front side of the plastic film 10; in use, the three-dimensional raised portion 13 is embedded in the nose of the simulated person to make it fit better, and at the same time, the front and back sides of the plastic film 10 can also be distinguished by the concave and convex surface of the three-dimensional raised portion 13.
