Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a breathing mask. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing the autonomous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and they occupy a very important position in the field of modern medicine. A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. Respiratory masks are widely used in non-invasive breathing with ventilators, but existing respiratory masks can only be used for patient respiratory support, because inserting a gastric tube and then wearing a respiratory mask will cause the respiratory mask to leak, and the patient needs to be fed and watered. When feeding, the respiratory mask often needs to be unplugged, which affects the effect of respiratory treatment and easily causes the patient to hold his breath and lack of oxygen.

[0003] The utility model application document with application number 201820390723.0 discloses a ventilator mask with a gastric tube groove, in which the gastric tube drainage port is designed as a curved tube, passing through the breathing mask, and the connection edge is sealed by a sealing gasket. However, the drainage port designed as a curved tube is not conducive to food drainage when feeding patients, and is prone to blockage at the curved tube. A single sealing gasket is used at the connection between the breathing mask and the gastric tube, which has poor sealing performance and the gastric tube is very easy to fall out of the breathing mask during clinical use.

[0004] The utility model application document with application number 201721597794.X discloses a breathing mask that can be inserted with a gastric tube. A through hole is opened on the oxygen mask, and the gastric tube is inserted into the patient's nasal cavity through the through hole and enters the patient's tail. When not in use, the through hole is sealed by a seal so as not to affect the patient's breathing. However, the gastric tube in the utility model cannot be connected to the breathing mask, that is, the gastric tube must be inserted every time the patient needs to eat, which increases the patient's pain. For this reason, an improved breathing mask is designed. Utility Model Content

[0040] Embodiment 1:

[0041] like Figure 1-6 Specifically, a breathing mask comprises a mask body 1 that can be worn on the face of a patient, a breathing tube connector 11 that is detachably connected to a breathing tube is provided on the mask body 1, and a stomach tube connector 2 that is detachably connected to a stomach tube 01 is also provided. The stomach tube connector 2 comprises;

[0042] A first connector 21 fixedly connected to the mask body 1, the end of the first connector 21 close to the patient's face is the rear end, and the rear end of the first connector 21 is connected to a gastric tube 01 that needs to be inserted into the patient's stomach;

[0043] A second connector 22, one end of which is sealed and detachably connected to the front end of the first connector 21, and the other end of the second connector 22 is connected to another stomach tube 01;

[0044] The cover cap 23 is threadedly connected to one end of the two connectors connected to the stomach tube 01.

[0045] The breathing mask is provided with a stomach tube connection part 2 which is detachably connected to the stomach tube 01. The stomach tube connection part 2 includes a second connector 22 and a first connector 21, wherein one end of the first connector 21 is connected to the stomach tube 01 inserted into the patient's stomach, and the other end is detachably connected to the second connector 22. The other end of the second connector 22 is also connected to a stomach tube 01, and the stomach tube 01 can be connected to liquid food. The liquid food enters the stomach tube connection part 2 through the stomach tube 01 and then enters the patient's stomach through the stomach tube 01. Since the second connector 22 and the first connector 21 are detachably connected, the second connector 22 can be connected to the first connector 21 when eating to deliver liquid food. After eating, the second connector 22 and the associated stomach tube 01 can be removed and connected the next time you eat. In this way, there is no need to insert a stomach tube every time you eat, thereby reducing the pain of the patient.

[0046] In this example, the first connector 21 includes: a first base 211, the first base 211 is sealed and connected to the mask body 1, and part of the first base 211 is exposed on the inner side of the mask body 1; a connecting pipe 212 integrally connected to the first base 211, two locking blocks 213 are symmetrically arranged on the outer wall of the front end of the connecting pipe 212, and a slot 2131 is opened on the locking block 213 along its length direction, and the rear end of the connecting pipe 212 is provided with a nozzle 214 connected to the gastric tube 01. The connection method between the gastric tube 01 and the nozzle 214 adopts a conventional setting method similar to the connection method between the infusion syringe and the infusion tube, so it will not be described in detail. When not eating, the port of the connecting pipe 212 of the first connector 21 can be blocked by a plugging head, and the specific plugging head can be a commonly used rubber plug or medical cotton.

[0047] In this example, the second connector 22 includes: a second base 221; a guide tube 222, which is integrally connected to the second base 221 and can extend into the interior of the connecting pipe 212. The guide tube 222 is connected to a nozzle (not shown in the figure) connected to the stomach tube 01, and the structure is the same as the nozzle 214 on the first connector 21; a sealing ring seat 223, which is arranged at the connection between the guide tube 222 and the second base 221 and can seal the pipe opening of the connecting pipe 212; and plug connectors 224 symmetrically arranged on both sides of the guide tube 222, which can be inserted into the slot 2131. The slot 2131 is a rectangular slot, and the plug connector 224 includes a plate-like portion 2241 and a stopper 2242. One end of the plate-like portion 2241 is fixedly connected to the second base 221, and the stopper 2242 is integrally connected to the other end of the plate-like portion 2241. The plug connector 224 is made of medical plastic and has elasticity. A locking block 213 is arranged on the outer periphery of the connecting pipe 212, and a slot 2131 is designed on the locking block 213. Elastic plug connectors 224 are designed on both sides of the guide tube 222 of the second connector 22. The plug connector 224 and the slot 2131 are connected by a buckle connection to facilitate disassembly and connection. Specifically, a limit block 2242 with a triangular cross-sectional shape is arranged at the end of the plug connector 224. After the limit block 2242 is inserted into the slot 2131, it is reset under the action of elasticity to press against the end of the slot 2131 to limit and form a relatively stable connection. At the same time, a sealing ring seat 223 is arranged at the connection between the guide tube 222 and the second base 221, which can play a sealing role and ensure the sealing of the mask body (1).

[0048] In this example, a through hole is provided on the cap 23 for the stomach tube 01 to pass through. A silicone sealing ring 13 is provided circumferentially on the inner side of the mask body 1, and a mask fixing belt 12 is connected to both sides of the mask body 1.

[0049] Working principle: When in use, first loosen the cap 23 at the rear end of the first connecting head 21, then connect a gastric tube 01 to the nozzle 214 of the first connecting head 21 through the through hole of the cap 23, tighten the cap 23, and at the same time connect the other gastric tube 01 to the second connecting head 22 in the same way. When you need to eat, you only need to connect the second connecting head 22 to the first connecting head 21 to achieve the connection between the two gastric tubes 01 to deliver liquid food. The liquid food enters the gastric tube connecting part 2 through the gastric tube 01 and then enters the patient's stomach through the gastric tube 01. Since the second connecting head 22 and the first connecting head 21 are detachably connected, the second connecting head 22 and the associated gastric tube 01 can be removed after eating, and reconnected the next time you eat. In this way, there is no need to insert a gastric tube every time you eat, thereby reducing the pain of the patient.
